docker swarm create service failed when pull images from private registry

Question

As a docker beginner, I have built a swarm cluster on 5 Linux server. (docker version 17.12.0-ce)

But when I create a service, I see docker service ps command shows "pulling image failed" error="pull access denied for registry.xxxx.xxx.

I'm using a private registry which should be use docker login at first.

So, how to do the login action when creating a swarm service ?

Answer 1

You need to pass the --with-registry-auth flag on docker service create to pass your credentials.

1. Authenticate if you're not logged in to your private registry (docker login ..)
2. Create your service: docker service create --with-registry-auth --name my-service my_repo/image:latest
