Support: Help needed using private Docker registry with Swarm

[matthewdolman]

Expected Behaviour

I am developing the function locally, I build locally and push the image to my git repository. Then I deploy to open-faas server. The open-faas server should pull the image from the git repository and deploy the function.

Current Behaviour

The image for the function should be pulled by the faas server and the function deployed.

Possible Solution

Steps to Reproduce (for bugs)

1. In stack.yml image for the function is my.gitlab.com/project/function:latest
   2 .faas-cli up -f stack.yml -g http://my-gateway:8080

Context

It seems that this should be pretty standard behaviour and I do not know if I am doing something wrong.

Hi,

Thanks for using OpenFaaS.

This functionality is a core feature of OpenFaaS. I'm not aware of any issues.

Do you use authentication with your registry? If so you'll need to send your registry authentication over the wire on each deployment, see faas-cli deploy --help

  -a, --send-registry-auth       send registryAuth from Docker credentials manager with the request

Can we clarify some terminology here, please? The image should be pushed to and pulled from a container registry, rather than a git repo. Are you using the container registry feature of Gitlab?

What is the output of faas-cli up -f stack.yml -g http://my-gateway:8080?

Alex's response fixed the issue.

GitLab has a container registry as well as being a git repo.

Derek close: resolved

Thanks for closing Richard.

FYI -a, --send-registry-auth is only required for Swarm. Kubernetes handles registry auth in a more decoupled way. (more in the docs)
