		Long: `This step allows you to update the deployment manifest for Kubernetes in a git repository.

It can for example be used for GitOps scenarios where the update of the manifests triggers an update of the corresponding deployment in Kubernetes.

As of today, it supports the update of deployment yaml files via kubectl patch, update a whole helm template and kustomize.

For *kubectl* the container inside the yaml must be described within the following hierarchy: ` + "`" + `{"spec":{"template":{"spec":{"containers":[{...}]}}}}` + "`" + `
For *helm* the whole template is generated into a single file (` + "`" + `filePath` + "`" + `) and uploaded into the repository.
For *kustomize* the ` + "`" + `images` + "`" + ` section will be update with the current image.`,
