Use sh instead of bash for scripts/slack
What does this MR do and why?
This was originally implemented in !97249 (merged) targeting ruby3-sync
branch, which uses curlimages/curl
image which doesn't have bash
installed: https://gitlab.com/gitlab-org/gitlab/-/jobs/2991619602
It's proven working after switching to /bin/sh
: https://gitlab.com/gitlab-org/gitlab/-/jobs/3046126754
In the default branch, we're using alpine
which shouldn't have bash
installed either, but we're installing it in the job: https://gitlab.com/gitlab-org/gitlab/-/blob/bee7cc717ec820b47a8e619e2298e97d17723288/.gitlab/ci/notify.gitlab-ci.yml#L9
I think this should work with /bin/sh
, and maybe we don't need to install bash
anymore. Actually, it doesn't seem like we need git
either? Maybe we can just switch alpine
to curlimages/curl
and don't install any other packages. Happy to do that or we can just go with this first.
