More information [here](https://github.com/external-secrets/kubernetes-external-secrets/issues/554#issuecomment-728984416).\n\n# Kubernetes External Secrets\n\nKubernetes External Secrets allows you to use external secret\nmanagement systems, like [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/) or\n[HashiCorp Vault](https://www.vaultproject.io/), to securely add secrets in\nKubernetes. Read more about the design and motivation for Kubernetes\nExternal Secrets on the [GoDaddy Engineering\nBlog](https://godaddy.github.io/2019/04/16/kubernetes-external-secrets/).\n\nThe community and maintainers of this project and related Kubernetes\nsecret management projects use the\n[`#external-secrets`](https://kubernetes.slack.com/archives/C017BF84G2Y)\nchannel on the Kubernetes slack for discussion and brainstorming.\n\n## How it works\n\nThe project extends the Kubernetes API by adding an `ExternalSecrets` object using [Custom Resource Definition](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) and a controller to implement the behavior of the object itself.\n\nAn `ExternalSecret` declares how to fetch the secret data, while the controller converts all `ExternalSecrets` to `Secrets`.\nThe conversion is completely transparent to `Pods` that can access `Secrets` normally.\n\nBy default `Secrets` are not encrypted at rest and are open to attack, either via the `etcd` server or via backups of `etcd` data.\nTo mitigate this risk, use an\n[external secret management system with a KMS plugin](https://kubernetes.io/docs/tasks/administer-cluster/kms-provider/)\nto encrypt `Secrets` stored in `etcd`.\n\n## System architecture\n\n![Architecture](architecture.png)\n\n1. `ExternalSecrets` are added in the cluster (e.g., `kubectl apply -f external-secret-example.yml`)\n1. Controller fetches `ExternalSecrets` using the Kubernetes API\n1. Controller uses `ExternalSecrets` to fetch secret data from external providers (e.g, AWS Secrets Manager)\n1. Controller upserts `Secrets`\n1. `Pods` can access `Secrets` normally\n\n## How to use it\n\n### Install with Helm\n\nThe official [helm chart](charts/kubernetes-external-secrets) can be used to create the `kubernetes-external-secrets` resources and `Deployment` on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.\n\n```bash\n$ helm repo add external-secrets https://external-secrets.github.io/kubernetes-external-secrets/\n$ helm install [RELEASE_NAME] external-secrets/kubernetes-external-secrets\n```\n\nFor more details about configuration see the [helm chart docs](charts/kubernetes-external-secrets/README.md)\n\n### Install with kubectl\n\nIf you don't want to install helm on your cluster and just want to use `kubectl` to install `kubernetes-external-secrets`, you could get the `helm` client cli first and then use the following sample command to generate kubernetes manifests:\n\n```bash\n$ helm template --include-crds --output-dir ./output_dir external-secrets/kubernetes-external-secrets\n```\n\nThe generated kubernetes manifests will be in `./output_dir` and can be applied to deploy `kubernetes-external-secrets` to the cluster.\n\n### Secrets Manager access\n\nFor `kubernetes-external-secrets` to be able to retrieve your secrets it will need access to your secret backend.\n\n#### AWS based backends\n\nAccess to AWS secrets backends (SSM \u0026 secrets manager) can be granted in various ways:\n\n1. Granting your nodes explicit access to your secrets using the [node instance role](https://docs.aws.amazon.com/eks/latest/userguide/worker_node_IAM_role.html) (easy for experimentation, not recommended)\n\n2. [IAM roles for service accounts](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html).\n\n3. Per pod IAM authentication: [kiam](https://github.com/uswitch/kiam) or [kube2iam](https://github.com/jtblin/kube2iam).\n\n4. Directly provide AWS access credentials to the `kubernetes-external-secrets` pod by environmental variables.\n\nOptionally configure custom endpoints using environment variables\n - [AWS_SM_ENDPOINT](https://docs.aws.amazon.com/general/latest/gr/asm.html) - Useful to set endpoints for FIPS compliance.\n - [AWS_STS_ENDPOINT](https://docs.aws.amazon.com/general/latest/gr/sts.html) - Useful to set endpoints for FIPS compliance or regional latency.\n - [AWS_SSM_ENDPOINT](https://docs.aws.amazon.com/general/latest/gr/ssm.html) - Useful to set endpoints for FIPS compliance or custom VPC endpoint.\n\n##### Using AWS access credentials\n\nSet `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` env vars in the `kubernetes-external-secrets` session/pod.\nYou can use `envVarsFromSecret` in the helm chart to create these env vars from existing k8s secrets.\n\nAdditionally, you can specify a `roleArn` which will be assumed before retrieving the secret.\nYou can limit the range of roles which can be assumed by this particular _namespace_ by using annotations on the namespace resource. The annotation key is configurable (see [above](#aws-based-backends)). The annotation value is evaluated as a regular expression and tries to match the `roleArn`.\n\n```yaml\nkind: Namespace\nmetadata:\n  name: iam-example\n  annotations:\n    # annotation key is configurable\n    iam.amazonaws.com/permitted: \"arn:aws:iam::123456789012:role/.*\"\n```\n\n### Add a secret\n\nAdd your secret data to your backend. For example, AWS Secrets Manager:\n\n```\naws secretsmanager create-secret --name hello-service/password --secret-string \"1234\"\n```\n\nAWS Parameter Store:\n\n```\naws ssm put-parameter --name \"/hello-service/password\" --type \"String\" --value \"1234\"\n```\n\nand then create a `hello-service-external-secret.yml` file:\n\n```yml\napiVersion: \"kubernetes-client.io/v1\"\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: secretsManager\n  # optional: specify role to assume when retrieving the data\n  roleArn: arn:aws:iam::123456789012:role/test-role\n  data:\n    - key: hello-service/password\n      name: password\n  # optional: specify a template with any additional markup you would like added to the downstream Secret resource.\n  # This template will be deep merged without mutating any existing fields. For example: you cannot override metadata.name.\n  template:\n    metadata:\n      annotations:\n        cat: cheese\n      labels:\n        dog: farfel\n```\n\nor\n\n```yml\napiVersion: \"kubernetes-client.io/v1\"\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: systemManager\n  data:\n    - key: /hello-service/password\n      name: password\n```\n\nThe following IAM policy allows a user or role to access parameters matching `prod-*`.\n\n```json\n{\n  \"Version\": \"2012-10-17\",\n  \"Statement\": [\n    {\n      \"Effect\": \"Allow\",\n      \"Action\": \"ssm:GetParameter\",\n      \"Resource\": \"arn:aws:ssm:us-west-2:123456789012:parameter/prod-*\"\n    }\n  ]\n}\n```\n\nThe IAM policy for Secrets Manager is similar ([see docs](https://docs.aws.amazon.com/mediaconnect/latest/ug/iam-policy-examples-asm-secrets.html)):\n\n```json\n{\n  \"Version\": \"2012-10-17\",\n  \"Statement\": [\n    {\n      \"Effect\": \"Allow\",\n      \"Action\": [\n        \"secretsmanager:GetResourcePolicy\",\n        \"secretsmanager:GetSecretValue\",\n        \"secretsmanager:DescribeSecret\",\n        \"secretsmanager:ListSecretVersionIds\"\n      ],\n      \"Resource\": [\n        \"arn:aws:secretsmanager:us-west-2:111122223333:secret:aes128-1a2b3c\",\n        \"arn:aws:secretsmanager:us-west-2:111122223333:secret:aes192-4D5e6F\",\n        \"arn:aws:secretsmanager:us-west-2:111122223333:secret:aes256-7g8H9i\"\n      ]\n    }\n  ]\n}\n```\n\nSave the file and run:\n\n```sh\nkubectl apply -f hello-service-external-secret.yml\n```\n\nWait a few minutes and verify that the associated `Secret` has been created:\n\n```sh\nkubectl get secret hello-service -o=yaml\n```\n\nThe `Secret` created by the controller should look like:\n\n```yml\napiVersion: v1\nkind: Secret\nmetadata:\n  name: hello-service\n  annotations:\n    cat: cheese\n  labels:\n    dog: farfel\ntype: Opaque\ndata:\n  password: MTIzNA==\n```\n\n### Create secrets of other types than opaque\n\nYou can override `ExternalSecret` type using `template`, for example:\n\n```yaml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-docker\nspec:\n  backendType: systemManager\n  template:\n    type: kubernetes.io/dockerconfigjson\n  data:\n    - key: /hello-service/hello-docker\n      name: .dockerconfigjson\n```\n\n### Templating\n\nKubernetes External Secrets supports templating in `ExternalSecret` using [lodash.template](https://lodash.com/docs/4.17.15#template).\n\nTemplate is applied to all `ExternalSecret.template` sections of the manifest.\nData retrieved from secure backend is available via the `data` variable.\nAdditonal object `yaml` of instance of [js-yaml](https://github.com/nodeca/js-yaml) is available in `lodash` templates.\nIt can be leveraged for easier YAML content manipulation.\n\nTemplating can be used for:\n\n- Generating K8S `Secret` keys:\n  - upserting plain text via `ExternalSecret.template.stringData`\n  - upserting base64 encoded content `ExternalSecret.template.data`\n- For creating dynamic labels, annotations and other fields available in K8S `Secret` object.\n\nTo demonstrate templating functionality let's assume the secure backend, e.g. Hashicorp Vault, contains the following data\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ekv/extsec/secret1\u003c/th\u003e\n\u003cth\u003ekv/extsec/secret2\u003c/th\n\u003c/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\n```json\n{\n  \"intKey\": 11,\n  \"objKey\": {\n    \"strKey\": \"hello world\"\n  }\n}\n```\n\n\u003c/td\u003e\n\u003ctd\u003e\n\n```json\n{\n  \"arrKey\": [1, 2, 3]\n}\n```\n\n\u003c/td\u003e\n\u003c/tr\u003e\n\u003c/table\u003e\n\nThen, one could create the following `ExternalSecret`\n\n```yaml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: tmpl-ext-sec\nspec:\n  backendType: vault\n  data:\n    - key: kv/data/extsec/secret1\n      name: s1\n    - key: kv/data/extsec/secret2\n      name: s2\n  kvVersion: 2\n  template:\n    data:\n      file.txt: |\n        \u003c%= Buffer.from(JSON.stringify(JSON.parse(data.s1).objKey)).toString(\"base64\") %\u003e\n    metadata:\n      labels:\n        label1: \u003c%= JSON.parse(data.s1).intKey %\u003e\n        label2: \u003c%= JSON.parse(data.s1).objKey.strKey.replace(\" \", \"-\") %\u003e\n    stringData:\n      file.yaml: |\n        \u003c%= yaml.dump(JSON.parse(data.s1)) %\u003e\n        \u003c% let s2 = JSON.parse(data.s2) %\u003e\u003c% s2.arrKey.forEach((e, i) =\u003e { %\u003earr_\u003c%= i %\u003e: \u003c%= e %\u003e\n        \u003c% }) %\u003e`\n  vaultMountPoint: kubernetes\n  vaultRole: demo\n```\n\nAfter applying this `ExternalSecret` to the K8S cluster, the operator will generate following `Secret`\n\n```yaml\napiVersion: v1\ndata:\n  file.txt: eyJzdHJLZXkiOiJoZWxsbyB3b3JsZCJ9\n  file.yaml: aW50S2V5OiAxMQpvYmpLZXk6CiAgc3RyS2V5OiBoZWxsbyB3b3JsZAoKYXJyXzA6IDEKYXJyXzE6IDIKYXJyXzI6IDMKYAo=\n  s1: eyJpbnRLZXkiOjExLCJvYmpLZXkiOnsic3RyS2V5IjoiaGVsbG8gd29ybGQifX0=\n  s2: eyJhcnJLZXkiOlsxLDIsM119\nkind: Secret\nmetadata:\n  name: tmpl-ext-sec\n  labels:\n    label1: \"11\"\n    label2: hello-world\ntype: Opaque\n```\n\nResulting `Secret` could be inspected to see that result is generated by `lodash` templating engine\n\n```bash\n$ kubectl get secret/tmpl-ext-sec -ogo-template='{{ index .data \"s1\" | base64decode }}'\n{\"intKey\":11,\"objKey\":{\"strKey\":\"hello world\"}}\n\n$ kubectl get secret/tmpl-ext-sec -ogo-template='{{ index .data \"s2\" | base64decode }}'\n{\"arrKey\":[1,2,3]}\n\n$ kubectl get secret/tmpl-ext-sec -ogo-template='{{ index .data \"file.txt\" | base64decode }}'\n{\"strKey\":\"hello world\"}\n\n$ kubectl get secret/tmpl-ext-sec -ogo-template='{{ index .data \"file.yaml\" | base64decode }}'\nintKey: 11\nobjKey:\n  strKey: hello world\n\narr_0: 1\narr_1: 2\narr_2: 3\n\n$ kubectl get secret/tmpl-ext-sec -ogo-template='{{ .metadata.labels }}'\nmap[label1:11 label2:hello-world]\n```\n\n## Scoping access\n\n### Using Namespace annotation\n\nEnforcing naming conventions for backend keys could be done by using namespace annotations.\nBy default an `ExternalSecret` may access arbitrary keys from the backend e.g.\n\n```yml\ndata:\n  - key: /dev/cluster1/core-namespace/hello-service/password\n    name: password\n```\n\nAn enforced naming convention helps to keep the structure tidy and limits the access according\nto your naming schema.\n\nConfigure the schema as a regular expression in the namespace using an annotation.\nThis allows `ExternalSecrets` in `core-namespace` only access to secrets that start with\n`/dev/cluster1/core-namespace/`:\n\n```yaml\nkind: Namespace\nmetadata:\n  name: core-namespace\n  annotations:\n    # annotation key is configurable\n    externalsecrets.kubernetes-client.io/permitted-key-name: \"/dev/cluster1/core-namespace/.*\"\n```\n\n### Using ExternalSecret controller config\n\nExternalSecret config allows scoping the access of kubernetes-external-secrets controller.\nThis allows deployment of multiple kubernetes-external-secrets instances in the same cluster\nand each instance can access a set of predefined namespaces.\n\nTo enable this option, set the env var in the controller side to a list of namespaces:\n\n```yaml\nenv:\n  WATCHED_NAMESPACES: \"default,qa,dev\"\n```\n\n### Using ExternalSecret config\n\nExternalSecret manifest allows scoping the access of kubernetes-external-secrets controller.\nThis allows deployment of multiple kubernetes-external-secrets instances at the same cluster\nand each instance can access a set of ExternalSecrets.\n\nTo enable this option, set the env var in the controller side:\n```yaml\nenv:\n  INSTANCE_ID: \"dev-team-instance\"\n```\n\nAnd in ExternalSecret side:\n```yaml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: foo\nspec:\n  controllerId: 'dev-team-instance'\n[...]\n```\n\n**Please note**\n\nScoping access by ExternalSecret config provides only a logical separation and it doesn't cover the security aspects.\ni.e it assumes that the security side is managed by another component like Kubernetes Network policies\nor Open Policy Agent.\n\n## Deprecations\n\nA few properties have changed name overtime, we still maintain backwards compatbility with these but they will eventually be removed, and they are not validated using the CRD validation.\n\n| Old                          | New                           |\n| ---------------------------- | ----------------------------- |\n| `secretDescriptor`           | `spec`                        |\n| `spec.type`                  | `spec.template.type`          |\n| `spec.properties`            | `spec.data`                   |\n| `backendType: secretManager` | `backendType: secretsManager` |\n\n## Backends\n\nkubernetes-external-secrets supports AWS Secrets Manager, AWS System Manager, Akeyless, Hashicorp Vault, Azure Key Vault, Google Secret Manager and Alibaba Cloud KMS Secret Manager.\n\n### AWS Secrets Manager\n\nkubernetes-external-secrets supports both JSON objects (\"Secret\nkey/value\" in the AWS console) or strings (\"Plaintext\" in the AWS\nconsole). Using JSON objects is useful when you need to atomically\nupdate multiple values. For example, when rotating a client\ncertificate and private key.\n\nWhen writing an ExternalSecret for a JSON object you must specify the\nproperties to use. For example, if we add our hello-service\ncredentials as a single JSON object:\n\n```\naws secretsmanager create-secret --region us-west-2 --name hello-service/credentials --secret-string '{\"username\":\"admin\",\"password\":\"1234\"}'\n```\n\nWe can declare which properties we want from `hello-service/credentials`:\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: secretsManager\n  # optional: specify role to assume when retrieving the data\n  roleArn: arn:aws:iam::123456789012:role/test-role\n  # optional: specify region\n  region: us-east-1\n  data:\n    - key: hello-service/credentials\n      name: password\n      property: password\n    - key: hello-service/credentials\n      name: username\n      property: username\n    - key: hello-service/credentials\n      name: password_previous\n      # Version Stage in Secrets Manager\n      versionStage: AWSPREVIOUS\n      property: password\n    - key: hello-service/credentials\n      name: password_versioned\n      # Version ID in Secrets Manager\n      versionId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\n      property: password\n```\n\nalternatively you can use `dataFrom` and get all the values from `hello-service/credentials`:\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: secretsManager\n  # optional: specify role to assume when retrieving the data\n  roleArn: arn:aws:iam::123456789012:role/test-role\n  # optional: specify region\n  region: us-east-1\n  dataFrom:\n    - hello-service/credentials\n```\n\n`dataFrom` by default retrieves the latest (`AWSCURRENT`) version of the backend secret, if you want to get values in bulk of a specific version, you can use `dataFromWithOptions`:\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: secretsManager\n  # optional: specify role to assume when retrieving the data\n  roleArn: arn:aws:iam::123456789012:role/test-role\n  # optional: specify region\n  region: us-east-1\n  dataFromWithOptions:\n    - key: hello-service/credentials\n      versionStage: AWSPREVIOUS\n    - key: hello-service/credentials\n      versionId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\n```\n\n`data`, `dataFrom` and `dataFromWithOptions` can of course be combined, any naming conflicts will use the last defined.   \nIn the below example `data` takes precedence over `dataFromWithOptions` and `dataFrom`.\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: secretsManager\n  # optional: specify role to assume when retrieving the data\n  roleArn: arn:aws:iam::123456789012:role/test-role\n  # optional: specify region\n  region: us-east-1\n  dataFrom:\n    - hello-service/credentials\n  dataFromWithOptions:\n    - key: hello-service/credentials\n      versionId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\n  data:\n    - key: hello-service/migration-credentials\n      name: password\n      property: password\n```\n\n### AWS SSM Parameter Store\n\nYou can scrape values from SSM Parameter Store individually or by providing a path to fetch all keys inside.\n\nWhen fetching all keys by path, you can also recursively scrape all the sub paths (child paths) if you need to. The default is not to scrape child paths.\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: systemManager\n  # optional: specify role to assume when retrieving the data\n  roleArn: arn:aws:iam::123456789012:role/test-role\n  # optional: specify region\n  region: us-east-1\n  data:\n    - key: /foo/name\n      name: fooName\n    - path: /extra-people/\n      recursive: false\n```\n\n`data` and `dataFrom` retrieve the latest version of the parameter by default. If you want to get values for a specific version, you can append the version number to the key:\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: systemManager\n  # optional: specify role to assume when retrieving the data\n  roleArn: arn:aws:iam::123456789012:role/test-role\n  # optional: specify region\n  region: us-east-1\n  dataFrom:\n    - hello-service/credentials:3\n  data:\n    - key: /foo/name\n      name: fooName:5\n```\n\n### Akeyless Vault\n\nkubernetes-external-secrets supports fetching secrets from [Akeyless Vault](https://www.akeyless.io/), .\nYou will need to set the following environment variables: \n\n```yml\nenv:\n  #akeyless rest-v2 endpoint \n  AKEYLESS_API_ENDPOINT:  https://api.akeyless.io \n  AKEYLESS_ACCESS_ID: \n  #AKEYLESS_ACCESS_TYPE can be one of the following: aws_iam/azure_ad/gcp/access_key\n  AKEYLESS_ACCESS_TYPE: \n  #AKEYLESS_ACCESS_TYPE_PARAM can be one of the following: gcp-audience/azure-obj-id/access-key\n  #AKEYLESS_ACCESS_TYPE_PARAM:\n\n```\n\nOnce you have kubernetes-external-secrets installed, you can create an external secret with YAML like the following:\n\n```yml\napiVersion: 'kubernetes-client.io/v1'\nkind: ExternalSecret\nmetadata:\n  name: hello-secret\nspec:\n  backendType: akeyless\n  data:\n    - key: path/secret-name\n      name: password\n\n```\n\n### Hashicorp Vault\n\nkubernetes-external-secrets supports fetching secrets from [Hashicorp Vault](https://www.vaultproject.io/), using the [Kubernetes authentication method](https://www.vaultproject.io/docs/auth/kubernetes).\n\n```yml\nenv:\n  VAULT_ADDR: https://vault.domain.tld\n  DEFAULT_VAULT_MOUNT_POINT: \"k8s-auth\" # optional, default value to be used if not specified in the ExternalSecret\n  DEFAULT_VAULT_ROLE: \"k8s-auth-role\" # optional, default value to be used if not specified in the ExternalSecret\n```\n\nYou will need to set the `VAULT_ADDR` environment variables so that kubernetes-external-secrets knows which endpoint to connect to, then create `ExternalSecret` definitions as follows:\n\n```yml\napiVersion: \"kubernetes-client.io/v1\"\nkind: ExternalSecret\nmetadata:\n  name: hello-vault-service\nspec:\n  backendType: vault\n  # Your authentication mount point, e.g. \"kubernetes\"\n  # Overrides cluster DEFAULT_VAULT_MOUNT_POINT\n  vaultMountPoint: my-kubernetes-vault-mount-point\n  # The vault role that will be used to fetch the secrets\n  # This role will need to be bound to kubernetes-external-secret's ServiceAccount; see Vault's documentation:\n  # https://www.vaultproject.io/docs/auth/kubernetes.html\n  # Overrides cluster DEFAULT_VAULT_ROLE\n  vaultRole: my-vault-role\n  data:\n    - name: password\n      # The full path of the secret to read, as in `vault read secret/data/hello-service/credentials`\n      key: secret/data/hello-service/credentials\n      property: password\n    # Vault values are matched individually. If you have several keys in your Vault secret, you will need to add them all separately\n    - name: api-key\n      key: secret/data/hello-service/credentials\n      property: api-key\n```\n\nIf you use Vault Namespaces (a Vault Enterprise feature) you can set the namespace to interact with via the `VAULT_NAMESPACE` environment variable.\n\nThe Vault token obtained by Kubernetes authentication will be renewed as needed. By default the token will be renewed three poller intervals (POLLER_INTERVAL_MILLISECONDS) before the token TTL expires. The default should be acceptable in most cases but the token renew threshold can also be customized by setting the `VAULT_TOKEN_RENEW_THRESHOLD` environment variable. The token renew threshold value is specified in seconds and tokens with remaining TTL less than this number of seconds will be renewed. In order to minimize token renewal load on the Vault server it is suggested that Kubernetes auth tokens issued by Vault have a TTL of at least ten times the poller interval so that they are renewed less frequently. A longer token TTL results in a lower token renewal load on Vault.\n\nIf Vault uses a certificate issued by a self-signed CA you will need to provide that certificate:\n\n```sh\n# Create secret with CA\nkubectl create secret generic vault-ca --from-file=./ca.pem\n```\n\n```yml\n# values.yaml\nenv:\n  VAULT_ADDR: https://vault.domain.tld\n  NODE_EXTRA_CA_CERTS: \"/usr/local/share/ca-certificates/ca.pem\"\n\nfilesFromSecret:\n  certificate-authority:\n    secret: vault-ca\n    mountPath: /usr/local/share/ca-certificates\n```\n\n### Azure Key Vault\n\nkubernetes-external-secrets supports fetching secrets from [Azure Key vault](https://azure.microsoft.com/en-ca/services/key-vault/)\n\nYou will need to set these env vars in the deployment of kubernetes-external-secrets:\n\n- `AZURE_TENANT_ID`\n- `AZURE_CLIENT_ID`\n- `AZURE_CLIENT_SECRET`\n  \nThe SP configured will require get and list access policies on the `AZURE_KEYVAULT_NAME`.\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-keyvault-service\nspec:\n  backendType: azureKeyVault\n  keyVaultName: hello-world\n  data:\n    - key: hello-service/credentials\n      name: password\n```\n\n### Alibaba Cloud KMS Secret Manager\n\nkubernetes-external-secrets supports fetching secrets from [Alibaba Cloud KMS Secret Manager](https://www.alibabacloud.com/help/doc-detail/152001.htm)\n\ncreate secret by using the [aliyun-cli](https://github.com/aliyun/aliyun-cli) command below:\n\n```bash\n# you need to configure aliyun-cli with a valid RAM user and proper permission\naliyun kms CreateSecret --SecretName my_secret --SecretData P@ssw0rd --VersionId 001\n```\n\nYou will need to set these env vars in the deployment of kubernetes-external-secrets:\n\n- `ALICLOUD_ACCESS_KEY_ID`\n- `ALICLOUD_ACCESS_KEY_SECRET`\n- `ALICLOUD_ENDPOINT`\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: alicloudSecretsManager\n  # optional: specify role to assume using provided access key ID and access key secret when retrieving the data\n  roleArn: acs:ram::{UID}:role/demo\n  data:\n    - key: hello-credentials1\n      name: password\n    - key: hello-credentials2\n      name: username\n      # Version Stage in Alibaba Cloud KMS Secrets Manager. Optional, default value is ACSCurrent\n      versionStage: ACSCurrent\n```\n\n### GCP Secret Manager\n\nkubernetes-external-secrets supports fetching secrets from [GCP Secret Manager](https://cloud.google.com/solutions/secrets-management)\n\nThe external secret will poll for changes to the secret according to the value set for `POLLER_INTERVAL_MILLISECONDS` in env. Depending on the time interval this is set to you may incur additional charges as Google Secret Manager [charges](https://cloud.google.com/secret-manager/pricing) per a set number of API calls.\n\nA service account is required to grant the controller access to pull secrets.\n\n#### Add a secret\n\nAdd your secret data to your backend using GCP SDK :\n\n```\necho -n '{\"value\": \"my-secret-value\"}' | gcloud secrets create my-gsm-secret-name --replication-policy=\"automatic\" --data-file=-\n```\n\nIf the secret needs to be updated :\n\n```\necho -n '{\"value\": \"my-secret-value-with-update\"}' | gcloud secrets versions add my-gsm-secret-name --data-file=-\n```\n\n##### Deploy kubernetes-external-secrets using Workload Identity\n\nInstructions are here: [Enable Workload Identity](https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity#enable_workload_identity_on_a_new_cluster). To enable workload identity on an existing cluster (which is not covered in that document), first enable it on the cluster like so:\n\n    gcloud container clusters update $CLUSTER_NAME --workload-pool=$PROJECT_NAME.svc.id.goog\n\nNext enable workload metadata config on the node pool in which the pod will run:\n\n    gcloud beta container node-pools update $POOL --cluster $CLUSTER_NAME --workload-metadata-from-node=GKE_METADATA_SERVER\n\nIf enabling it only for a particular pool, make sure to add any relevant tolerations or affinities:\n\n    tolerations:\n      - key: \"name\"\n        operator: \"Equal\"\n        effect: \"NoExecute\"\n        value: \"node-pool-taint\"\n      - key: \"name\"\n        operator: \"Equal\"\n        effect: \"NoSchedule\"\n        value: \"node-pool-taint\"\n\n    affinity:\n      nodeAffinity:\n        requiredDuringSchedulingIgnoredDuringExecution:\n          nodeSelectorTerms:\n            - matchExpressions:\n                - key: cloud.google.com/gke-nodepool\n                  operator: In\n                  values:\n                    - node-pool\n\nYou can add an annotation which is needed for workload identity by passing it in via Helm:\n\n    serviceAccount:\n      annotations:\n        iam.gke.io/gcp-service-account: my-secrets-sa@$PROJECT.iam.gserviceaccount.com\n\nCreate the policy binding:\n\n    gcloud iam service-accounts add-iam-policy-binding --role roles/iam.workloadIdentityUser --member \"serviceAccount:$CLUSTER_PROJECT.svc.id.goog[$SECRETS_NAMESPACE/kubernetes-external-secrets]\" my-secrets-sa@$PROJECT.iam.gserviceaccount.com\n\nGrant GCP service account access to secrets:\n\n    gcloud projects add-iam-policy-binding $PROJECT_ID --member=serviceAccount:my-secrets-sa@$PROJECT.iam.gserviceaccount.com --role=roles/secretmanager.secretAccessor\n\n##### Deploy kubernetes-external-secrets using a service account key\n\nAlternatively you can create and mount a kubernetes secret containing google service account credentials and set the `GOOGLE_APPLICATION_CREDENTIALS` env variable.\n\nCreate a Kubernetes secret called gcp-creds with a JSON keyfile from a service account with necessary credentials to access the secrets:\n\n    apiVersion: v1\n    kind: Secret\n    metadata:\n      name: mysecret\n    type: Opaque\n    stringData:\n      gcp-creds.json: |-\n        $KEYFILE_CONTENT\n\nUncomment `GOOGLE_APPLICATION_CREDENTIALS` in the values file as well as the following section:\n\n    env:\n      AWS_REGION: us-west-2\n      POLLER_INTERVAL_MILLISECONDS: 10000  # Caution, setting this frequency may incur additional charges on some platforms\n      LOG_LEVEL: info\n      METRICS_PORT: 3001\n      VAULT_ADDR: http://127.0.0.1:8200\n      GOOGLE_APPLICATION_CREDENTIALS: /app/gcp-creds/gcp-creds.json\n\n     filesFromSecret:\n       gcp-creds:\n         secret: gcp-creds\n         mountPath: /app/gcp-creds\n\nThis will mount the secret at `/app/gcp-creds/gcp-creds.json` and make it available via the `GOOGLE_APPLICATION_CREDENTIALS` environment variable.\n\n#### Usage\n\nOnce you have kubernetes-external-secrets installed, you can create an external secret with YAML like the following:\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: gcp-secrets-manager-example # name of the k8s external secret and the k8s secret\nspec:\n  backendType: gcpSecretsManager\n  projectId: my-gsm-secret-project\n  data:\n    - key: my-gsm-secret-name # name of the GCP secret\n      name: my-kubernetes-secret-name # key name in the k8s secret\n      version: latest # version of the GCP secret\n      property: value # name of the field in the GCP secret\n```\n\nThe field \"key\" is the name of the secret in Google Secret Manager. The field \"name\" is the name of the Kubernetes secret this external secret will generate. The metadata \"name\" field is the name of the external secret in Kubernetes.\n\nTo retrieve external secrets, you can use the following command:\n\n    kubectl get externalsecrets -n $NAMESPACE\n\nTo retrieve the secrets themselves, you can use the regular:\n\n    kubectl get secrets -n $NAMESPACE\n\nTo retrieve an individual secret's content, use the following where \"mysecret\" is the key to the secret content under the \"data\" field:\n\n    kubectl get secret my-secret -o 'go-template={{index .data \"mysecret\"}}' | base64 -D\n\nThe secrets will persist even if the helm installation is removed, although they will no longer sync to Google Secret Manager.\n\n### IBM Cloud Secrets Manager\n\nkubernetes-external-secrets supports fetching secrets from [IBM Cloud Secrets Manager](https://cloud.ibm.com/catalog/services/secrets-manager).\n\nCreate username_password secret by using the [UI, CLI or API](https://cloud.ibm.com/docs/secrets-manager?topic=secrets-manager-user-credentials).\nThe CLI option is illustrated below:\n\n```bash\n# You need to configure ibm cloud cli with a valid endpoint.\n# If you're using plug-in version 0.0.8 or later, export the following variable.\nexport SECRETS_MANAGER_URL=https://{instanceid}.{region}.secrets-manager.appdomain.cloud\n\n# If you're using plug-in version 0.0.6 or earlier, export the following variable.\nexport IBM_CLOUD_SECRETS_MANAGER_API_URL=https://{instance_ID}.{region}.secrets-manager.appdomain.cloud\n\nibmcloud secrets-manager secret-create --secret-type username_password \\\n  --metadata '{\"collection_type\": \"application/vnd.ibm.secrets-manager.secret+json\", \"collection_total\": 1}' \\\n  --resources '[{\"name\": \"example-username-password-secret\",\"description\": \"Extended description for my secret.\",\"username\": \"user123\",\"password\": \"cloudy-rainy-coffee-book\"}]'\n```\n\nYou will need to set these env vars in the deployment of kubernetes-external-secrets:\n\n- `IBM_CLOUD_SECRETS_MANAGER_API_APIKEY`\n- `IBM_CLOUD_SECRETS_MANAGER_API_ENDPOINT`\n- `IBM_CLOUD_SECRETS_MANAGER_API_AUTH_TYPE`\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: ibmcloud-secrets-manager-example\nspec:\n  backendType: ibmcloudSecretsManager\n  data:\n    # The guid id of the secret\n    - key: \u003cguid\u003e\n      name: username\n      property: username\n      secretType: username_password\n```\n\n\nAlternately, you can use `keyByName` on the spec to interpret keys as secret names, instead of IDs.\nUsing names is slightly less efficient than using IDs, but it makes your ExternalSecrets more robust, as they are not tied to a particular instance of a secret in a particular instance of Secrets Manager:\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: ibmcloud-secrets-manager-example\nspec:\n  backendType: ibmcloudSecretsManager\n  keyByName: true\n  data:\n    # The name of the secret\n    - key: my-creds\n      name: username\n      property: username\n      secretType: username_password\n```\n\n## Binary Secrets\n\nMost backends do not treat binary secrets any differently than text secrets. Since you typically store a binary secret as a base64-encoded string in the backend, you need to explicitly let the ExternalSecret know that the secret is binary, otherwise it will be encoded in base64 again.\nYou can do that with the `isBinary` field on the key. This is necessary for certificates and other secret binary files.\n\n```yml\napiVersion: kubernetes-client.io/v1\nkind: ExternalSecret\nmetadata:\n  name: hello-service\nspec:\n  backendType: anySupportedBackend\n  # ...\n  data:\n    - key: hello-service/archives/secrets_zip\n      name: secrets.zip\n      isBinary: true # Default: false\n    # also works with `property`\n    - key: hello-service/certificates\n      name: cert.p12\n      property: cert.p12\n      isBinary: true\n```\n\nAWS Secrets Manager is a notable exception to this. If you create/update a secret using [SecretBinary](https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_CreateSecret.html#API_CreateSecret_RequestSyntax) parameter of the API, then AWS API will return the secret data as `SecretBinary` in the response and ExternalSecret will handle it accordingly. In that case, you do not need to use the `isBinary` field.\n\nNote that `SecretBinary` parameter is not available when using the AWS Secrets Manager console. For any binary secrets (represented by a base64-encoded strings) created/updated via the AWS console, or stored in key-value pairs instead of text strings, you can just use the `isBinary` field explicitly as above.\n\n## Metrics\n\nkubernetes-external-secrets exposes the following metrics over a prometheus endpoint:\n\n| Metric                                             | Type    | Description                                                                                                                             | Example                                                                                                         |\n| -------------------------------------------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- |\n| `kubernetes_external_secrets_sync_calls_count`     | Counter | Number of sync operations by backend, secret name and status                                                                            | `kubernetes_external_secrets_sync_calls_count{name=\"foo\",namespace=\"example\",backend=\"foo\",status=\"success\"} 1` |\n| `kubernetes_external_secrets_last_sync_call_state` | Gauge   | State of last sync call of external secret, where -1 means the last sync_call was an error and 1 means the last sync_call was a success | `kubernetes_external_secrets_last_sync_call_state{name=\"foo\",namespace=\"example\",backend=\"foo\"} 1`              |\n\n## Development\n\n[Minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/) is a tool that makes it easy to run a Kubernetes cluster locally.\n\nStart minikube and the daemon.
