k8s-wait-for-multi

This is an implementation of k8s-wait-for that allows you to wait for multiple items in one process, so you only need to start one init container. This uses informers (wrapped in a sigs.k8s.io/controller-runtime/pkg/cache.Cache) to get the status updates for all the items that this application is waiting for.

It accepts arguments in the following formats:

• namespace,service,service-name
• namespace,job,job-name
• namespace,pod,pod-name
• service,service-name using the namespace from the --namespace, -n flag or default
• job,job-name using the namespace from the --namespace, -n flag or default
• pod,pod-name using the namespace from the --namespace, -n flag or default
• pod-name using the namespace from the --namespace, -n flag or default and the kind pod

For pods it waits until the pod is Ready (k8s.io/kubectl/pkg/util/podutils.IsPodReady) and Available (k8s.io/kubectl/pkg/util/podutils.IsPodAvailable).

For jobs it wait intil the Completed condition is true.

For services it will wait until all pods that match the service selector are Ready and Available (like above).
