Deploy manifest action for Kubernetes

Use this action to bake and deploy manifests to Kubernetes clusters.

Assumes that the deployment target K8s cluster context was set earlier in the workflow by using either azure/k8s-actions/aks-set-context or azure/k8s-actions/k8s-set-context

Artifact substitution

The deploy action takes as input a list of container images which can be specified along with their tags or digests. The same is substituted into the non-templatized version of manifest files before applying to the cluster to ensure that the right version of the image is pulled by the cluster nodes.

Manifest stability

Rollout status is checked for the Kubernetes objects deployed. This is done to incorporate stability checks while computing the task status as success/failure.

Secret handling

The manifest files specfied as inputs are augmented with appropriate imagePullSecrets before deploying to the cluster.
