docker-stack-wait-deploy

A script waiting for docker stack deploy command to complete.

Why

Unfortunately, docker stack deploy always run in detached mode. It means it exits immediately and doesn't wait for services to actually update. This repo provides script that does the following:

  • waits for all services in stack are updated (or errored)
  • displays update progress per instance of each service
  • returns exit code 0 in case of success and 1 in case of errors

Usage

After calling docker stack deploy $STACK_NAME call the following:

docker run --rm vitalets/docker-stack-wait-deploy | bash /dev/stdin $STACK_NAME

Example output (progress):
