[Buildroot] [PATCH] support/misc/gitlab-ci.yml.in: specify image to use

[Yann E. MORIN <yann.morin.1998@free.fr>]

Arnout, All,

On 2020-09-15 21:38 +0200, Arnout Vandecappelle (Essensium/Mind) spake thusly:
> Commit 93a2870966 split off the generated gitlab-ci.yml into a child
> pipeline. However, the generated gitlab-ci.yml file no longer had an
> 'image' tag.

Commit 93a2870966 still kept the image tag in the template. The removal
of the iamge tag was done later, see below...

> The result is that the jobs will use whatever image happens
> to be configured on the runner - which leads to frequent pipeline
> failures.

Do you have an example of such a pipeline (and its parent)?

> Fix this by explicitly specifying the image to use (the same one as in
> top-level .gitlab-ci.yml).

I was the one to explicitly remove it, because it is now supposed to be
added bny the script, with commit bef6739094 (gitlab-ci: share the image
version with the child):

    +preamble() {
    +    local template="${1}"
    +
    +    cat - "${template}" <<-_EOF_
    +       # This file is generated; do not edit!
    +       # Builds appear on https://gitlab.com/buildroot.org/buildroot/pipelines
    +
    +       image: ${CI_JOB_IMAGE}
    +
    +_EOF_
    +}

So the preamble is supposed to now contain the image name, the the
template.

And indeed it works for me:

    $ CI_JOB_IMAGE=FOOO support/scripts/generate-gitlab-ci-yml \
        support/misc/gitlab-ci.yml.in
    [...]
    image: FOOO
    [...]

And it looks like the tests I had done were also successfull:

    https://gitlab.com/ymorin/buildroot/-/pipelines/186530918
    https://gitlab.com/ymorin/buildroot/-/jobs/723345502
    https://gitlab.com/ymorin/buildroot/-/jobs/723345502/artifacts/file/generated-gitlab-ci.yml
     -> image: buildroot/base:20200814.2228

And so the jobs in the child pipeline use the expected image:

    https://gitlab.com/ymorin/buildroot/-/pipelines/186531247
    https://gitlab.com/ymorin/buildroot/-/jobs/723346533
     -> Using Docker executor with image buildroot/base:20200814.2228 ...

So, I'm not in favour of restoring the hard-coded version in the child
pipeline.

Regards,
Yann E. MORIN.
