Renovate: Artifact update problem with Elixir/Mix Repos

[philihp]

What Renovate type are you using?

I'm using the public Renovate bug. Not self-hosted.

Describe the bug

In updating an Elixir dependency, the PRs always report failure with the message

File name: mix.lock

Command failed: docker run --rm -v /mnt/renovate/gh/philihp/renobug:/mnt/renovate/gh/philihp/renobug -w /mnt/renovate/gh/philihp/renobug renovate/mix mix deps.update math
Unable to find image 'renovate/mix:latest' locally
docker: Error response from daemon: pull access denied for renovate/mix, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

To Reproduce

I created an empty project, configured renovate, and added some dependencies:

https://github.com/philihp/renobug

Additional context

I believe the problem lies on this line https://github.com/renovatebot/renovate/blob/53ca913/lib/manager/mix/artifacts.ts#L57, which is trying to find the image renovate/mix, while in DockerHub there is only an image renovate/elixir, but it doesn't have any downloads.

In digging more, #4496 seems that the build was originally committed to use the renovate/mix image. @KonstantinKurganov or @Zharinov, do you recall if that's intentional? Perhaps that image existed at the time and was removed?

It looks like we could have had a typo/mismatch from the start. @viceice do you think https://github.com/renovatebot/docker-elixir is still the best location to build it, or do you suggest any changes from buildpack?

[viceice]

I'll check the buildpack and the elixir repo. mix is included in elixir buildpack install tool.
