copier

Replicates all Secrets in the copier namespace that have label copier set to 'true' to all other namespaces in given cluster. It's just a mildly modifed example from shell-operator, therefore all credit belongs to the authors of the original.

Difference from 104-secret-copier

• doesn't need a custom container image (better for clusters without a private registry)
• easily deployable as a Kustomize remote base/build
• deployed as Deployment instead of just a Pod, therefore doesn't die when Pod is rescheduled
• different label and namespace name (secret-copier -> copier)
