Kubernetes Configuration Sync Operator

An operator to safely restart pods when configuration changes.

How it works

Configsyncop will watch your configmaps and secrets. If any annotated secret/configmap is modified, it will perform a rollout for any deployment, daemonset or statefulset using that secret/configmap.

Installation

1. Install RBAC permissions: kubectl apply -f rbac.yaml
2. Install main operator: kubectl apply -f deployment.yaml

Usage

1. Annotate your configmaps or secrets with k8s.config.sync.manage: "true".
2. Annotate your namespaces with k8s.config.sync.manage/Secret: "true" and/or k8s.config.sync.manage/ConfigMap: "true" to manage all Secrets or ConfigMaps in that namespace.

Examples

The folder example contains dummy secrets and configmaps. Just install them:

kubectl apply -f example/secret.yaml
kubectl apply -f example/configmap.yaml

Then you can install the deployments, daemonsets or statefulsets you want. There are four flavours:

• *-env-secret.yaml: uses the secret as an environment variable.
• *-volume-secret.yaml: uses the secret as a volume.
• *-env-cm.yaml: uses the configmap as an environment variable.
• *-volume-cm.yaml: uses the configmap as a volume.

Monitoring

Automatically exposes Prometheus metrics on port 9090.
