How do I create a service using an image from a private registry

Question

I have an image in a private registry,I wish to create a service from this image and deploy the service to docker-swarm. What's the way to achieve this?

Answer 1

Hey @Ruby, If your image is available on a private registry which requires login,use the --with-registry-auth flag with docker service create, after logging in. 

If your image is stored on registry.example.com, which is a private registry, use a command like the following:

$ docker login registry.example.com

$ docker service  create \
  --with-registry-auth \
  --name my_service \
  registry.example.com/acme/my_image:latest

This passes the login token from your local client to the swarm nodes where the service is deployed, using the encrypted WAL logs. With this information, the nodes are able to log into the registry and pull the image.

This will do!
