etcd-cloud-operator\n\n[![Docker Repository on Quay](https://quay.io/repository/quentin_m/etcd-cloud-operator/status \"Docker Repository on Quay\")](https://quay.io/repository/quentin_m/etcd-cloud-operator)\n\nMaintained by a former CoreOS engineer and inspired from the [etcd-operator](https://github.com/coreos/etcd-operator)\ndesigned for Kubernetes, the etcd-cloud-operator automatically bootstraps,\nmonitors, snapshots and recovers etcd clusters on cloud providers.\n\nUsed in place of the etcd binary and with minimal configuration, the operator\nhandles the configuration and lifecycle of etcd, based on data gathered from\nthe cloud provider and the status of the etcd cluster itself.\n\nIn other words, the operator operator is meant to help human operators sleep\nat night, while their mysterious etcd data store keeps running safely, even\nin the event of process, instance, network, or even availability-zone wide\nfailures.\n\n## Features\n\n-   _Resize_: By abstracting cluster management, resizing the cluster becomes\n    straightforward as the underlying auto-scaling group can simply be scaled as\n    desired.\n\n-   _Snapshots_: Periodically, snapshots of the entire key-value space are\n    captured, from each of the etcd members and uploaded to an encrypted external\n    storage, allowing the etcd (or human) operator to restore the store at a later\n    time, in any etcd cluster or instance.\n\n-   _Failure recovery_: Upon failure of a minority of the etcd members, the\n    managed members automatically restarts and rejoins the cluster without\n    breaking quorum or causing visible downtime - First by simply trying to rejoin\n    with their existing data set, otherwise trying to join as a new member with a\n    clean state, or by replacing the entire instance if necessary.\n\n-   _Disaster recovery_: In the event of a quorum loss, consequence of the\n    simultaneous failure of a majority of the members, the operator coordinates\n    to snapshot any live members and cleanly stop then, before seeding a new cluster\n    from the latest data revision available once the expected amount of instances\n    are ready to start again.\n\n-   _ACL support_: A user can configure the ACL of etcd by providing an **init-acl** config\n    in the config file. See [init-acl.md](./docs/init-acl.md) for more information.\n\n-   _JWT auth token support_: JWT auth token can be enabled by specifying the\n    `jwt-auth-token-config` in the config file, similar to the etcd \n    [-auth-token](https://etcd.io/docs/v3.3/op-guide/configuration/#--auth-token) flag.\n    The JWT auth token is **HIGHLY** recommended for \n    [production deployment](https://etcd.io/docs/v3.2/learning/auth_design/#two-types-of-tokens-simple-and-jwt),\n    especially when the **init-acl** config is also enabled, the JWT auth token can help\n    avoid the potential [invalid auth token issue](https://github.com/etcd-io/etcd/issues/9629).\n\nThe operator and etcd cluster can be easily configured using a [YAML file](config.example.yaml). The\nconfiguration notably includes clients/peers TLS encryption/authentication, with\nthe ability to automatically generate self-signed certificates if encryption\nis desired but authentication is not.\n\n## How to try it?\n\nRunning a managed etcd cluster using the operator is simply a matter of running\nthe operator binary in a supported auto-scaling group (as of today, AWS and Kubernetes only).\n\n-   _Docker_: Head over to [docs/docker-testing](docs/docker-testing) for a single-line local 3-nodes deployment.\n\n-   _AWS_: A Terraform [module](terraform/platforms/aws) is available to easily bring up production-grade etcd clusters\n    managed by the operator within AWS.\n\n-   _Kubernetes_: A basic [Helm chart](chart/etcd-cloud-operator) is available to quickly get started with a 3-nodes \n    StatefulSet.\n","funding_links":[],"categories":["Operator"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FQuentin-M%2Fetcd-cloud-operator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FQuentin-M%2Fetcd-cloud-operator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FQuentin-M%2Fetcd-cloud-operator/lists"}
