15.11-stable, Restore unavailable

[supar]

The entrypoint.sh script currently does not include any available restore methods. Having a restore method is essential for server migration purposes.
If you attempt to perform a migration from a container using the shell command docker compose exec gitlab sh, you may encounter the following error:

Backup::Error: gitaly-backup binary not found and gitaly_backup_path is not configured

This error occurs because the GitLab main image does not include the gitaly_backup binary from the gitaly image, which is required for the restore process.

Please note that in the prepare_dirs() method, the following directories are also required for installation during the restore scenario:

/home/git/gitlab/shared/terraform_state
/home/git/gitlab/shared/packages

I've never used the restore feature of gitlab, so I'd have to look into how to support that.

I have a makeshift solution

But there is problem with tar utility. While gitlab restores data it fails

rake aborted!

But if install full version of tar (add to setup.sh)

# add runtime dependencies
apk add --no-cache --virtual .gitlab-runtime \
        tar \
        git \

than build image fails

This is some kind of mystery. May be You know how to resolve this?

You need to install xz as well to be able to unpack tar.xz

[supar]

Yes, it works
