Create job to perform daily image updates
What does this MR do and why?
We originally intended the analyzer image to only contain the analyzer binary (i.e. a scratch
image).
Unfortunately, the GitLab runner requires a shell and grep
to be available. Given our attestation requirements, it is easier to use a base image than to copy the necessary binaries.
Since we now use an upstream image, it becomes necessary to rebuild it regularly so that the analyzer image contains the latest security updates.
This MR introduces a new job image update
which runs when TRIGGER_UPDATE
is set for a pipeline on the default branch.
Once the MR is merged, we need to create the scheduled job.
