Add alpine 3.15 as new runner/helper-image flavor
What does this MR do?
Partially related to !3184 (closed). This commit adds alpine 3.15 as new
runner/helper-image flavor option in addition to the existing
alpine 3.12
, 3.13
and 3.14
ones. Alpine 3.15 is the
latest stable release from November 2021 and the only one
which still actively receives bug-fixes:
https://alpinelinux.org/posts/Alpine-3.15.0-released.html
This release also contains a new Git version (from 2.32.0
to
2.34.1
) as well as a new Git-LFS version (from 2.13.1
to 3.0.2
) when comparing to alpine 3.14, containing
various new features and bug-fixes.
Why was this MR needed?
Git-LFS versions prior to 3.0.0
had an issue with improperly
handling GitLab's rate-limit header
(see the upstream PR addressing this topic).
MR !3184 (closed) already tries to address this partially yet based on
the gitlab-runner helper image's Dockerfile (see here),
it seems that the installed Git-LFS version is not derived from
the global version configuration (like it's done for the runner
image itself, see here)
but taken directly from alpine's package feed. The alpine 3.15
package feed already includes updated versions and hence resolves
the issue.
Besides that, the currently supported alpine 3.12
version
will be deprecated on the 1st of May 2022
and hence no longer receive any security updates. Having the
latest stable alpine version available as an option allows
users to already validate the new release and jump to it
directly instead of using an in-between version.
What's the best way to test this MR?
- Run a new CI pipeline using this MR and open the
helper images: [alpine3.15]
artefacts page. - Download the correct Docker image for your local platform (e.g.
prebuilt-alpine3.15-x86_64.tar.xz
) - Use
docker import
to import the packaged image and make it available locally, e.g:docker import ./prebuilt-alpine3.15-x86_64.tar.xz gitlab-runner-helper:alpine3.15-v14.6.0
. - Configure a local GitLab-Runner with the Docker executor to use the previously imported image as helper image, e.g:
helper_image = "gitlab-runner-helper:alpine3.15-v14.6.0"
. - Trigger various GitLab-CI pipelines with Git/Git-LFS objects to run on this local GitLab-Runner instance.
- Observe that the builds are successful and that the right helper image (see jobs logs) is used.
