regsecret-operator automates the creation of image pull secrets for one or more private registries in your namespaces.

It works watching namespaces events (optionally matching a selector) and creating the configured kubernetes.io/dockerconfigjson secrets for you.

Create a configuration file (ie. config.json):

{
  "secrets": [
    {
      "secretName": "regsecret",
      "credentials": {
        "https://index.docker.io/v1/": {
          "username": "my-username",
          "password": "my-password",
          "email": "my-email"
        }
      }
    }
  ]
}

Upload it as a secret in kubernetes:

kubectl -n kube-system create secret generic regsecret-operator-config --from-file=config=./config.json

Finally apply the deployment.yaml file contained in this repo:

kubectl apply -f https://raw.githubusercontent.com/mcasimir/regsecret-operator/master/deployment.yaml

If you plan to use a namespaceSelector be aware that labeling a namespace with kubectl label will not trigger any event. In this case, the chosen selector may not match the namespace immediately but only after the next resync (which will eventually happen but not so immediately).

Adding/changing labels by editing the namespace resource directly (ie. with kubectl edit or kubectl apply) does not have the same issue.
