"Stage Push Docker Image" : the built image is pushed into the Docker Hub Registry. "Stage Clear Images" : the images are removed from the host node. "Stage Deploy/Upgrade" : if the application deployment does not exist in the kubernetes cluster, then it is created. If it exists, then the image is updated to the new version.
