# keycloak-ext-operator
Creates OAuth clients in Keycloak and creates corresponding secrets in kubernetes.
Required environment:
| Environment variable | Purpose |
|-----------------------|-----------------------------------|
| `KEYCLOAK_URL` | URL to keycloak instance |
| `KEYCLOAK_USER` | Admin user name (usually `admin`) |
| `KEYCLOAK_PASSWORD` | Admin password |
By default, those values will be obtained from secret `keycloak` in `keycloak` namespace.
## Description
The operator:
- watches `KeycloakClient` manifests
- creates (or updates) OAuth private clients in Keycloak instance. If it's a new client, then secret will be randomly
generated
- creates secret with OAuth credentials
Tested on Keycloak 19. May not work on versions bellow 18 due to different API URLs.
**Example:**
Manifest (CRD)
```yaml
apiVersion: keycloak.k8s.reddec.net/v1alpha1
kind: KeycloakClient
metadata:
name: sample
namespace: default
spec:
secretName: "my-secret"
domain: "example.com"
realm: reddec
annotations:
foo: bar
labels:
alice: bob
```
- `secretName` is optional. If it is not set, then the name of CRD (`sample` in this case) will be used.
- `annotations` is optional. If set, all values will be copied to secret annotations.
- `labels` is optional. If set, all values will be copied to secret labels.
Generated secret
```yaml
apiVersion: v1
kind: Secret
metadata:
name: my-secret
namespace: default
immutable: true
type: Opaque
data:
clientID: ..... # unless copied from existent, it's equal to domain name
clientSecret: ..... # automatically generated secret (32 crypto random bytes represented as 64-bytes hex) or copied from existent client definition from keycloak.
realm: ..... # copied from spec
realmURL: ..... # full URL to realm: /realms/
discoveryURL: ..... # OIDC URL to realm: /realms//.well-known/openid-configuration
```
* unless `clientSecret` is copied from existent Keycloak client, it is automatically generated secret from 32 crypto
random bytes, and represented as 64-bytes hex
## Getting Started
* Install operator
```bash
curl -L https://github.com/reddec/keycloak-ext-operator/releases/latest/download/keycloak-ext-operator.yaml | \
kubectl apply -f -
```
* Setup credentials
```bash
kubectl -n keycloak create secret generic keycloak
kubectl -n keycloak edit secret keycloak
```
> values in `data` should be base64 encoded - see [kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret/)
example
```yaml
apiVersion: v1
kind: Secret
metadata:
name: keycloak
namespace: keycloak
data:
KEYCLOAK_URL: aHR0cHM6Ly9leGFtcGxlLmNvbQ==
KEYCLOAK_USER: YWRtaW4=
KEYCLOAK_PASSWORD: UEAkJHdvckQ=
```
