The name gitlab-runner clashes with a component of Gitlab CI with the
same name and only confuses people. It's now called gitlab-bundle and
a convenience-script gitlab-rake for easier invocation of rake tasks
was added. This was the primary use case of gitlab-runner.
Updates gitlab to the current stable version and fixes a lot of features that
were broken, at least with the current version and our configuration.
Quite a lot of sweat and tears has gone into testing nearly all features and
reading/patching the Gitlab source as we're about to deploy gitlab for our
whole company.
Things to note:
* The gitlab config is now written as a nix attribute set and will be
converted to JSON. Gitlab uses YAML but JSON is a subset of YAML.
The `extraConfig` opition is also an attribute set that will be merged
with the default config. This way *all* Gitlab options are supported.
* Some paths like uploads and configs are hardcoded in rails (at least
after my study of the Gitlab source). This is why they are linked from
the Gitlab root to /run/gitlab and then linked to the configurable
`statePath`.
* Backup & restore should work out of the box from another Gitlab instance.
* gitlab-git-http-server has been replaced by gitlab-workhorse upstream.
Push & pull over HTTPS works perfectly. Communication to gitlab is done
over unix sockets. An HTTP server is required to proxy requests to
gitlab-workhorse over another unix socket at
`/run/gitlab/gitlab-workhorse.socket`.
* The user & group running gitlab are now configurable. These can even be
changed for live instances.
* The initial email address & password of the root user can be configured.
Fixes #8598.
It turns out that installing therubytracer, with dependency on old v8, even
when using source libv8 version is problematic.
(see
http://stackoverflow.com/questions/21666379/problems-installing-gitlab-on-odroid-v8-lib-not-available).
But wait, rails does not even need therubytracer, just any kind of javascript
server side execution framework like nodejs. Well just use that, as also
suggested from different internet sources (look link above), it works just
fine.
I had to make several adjustments to make it work with nixos:
* Replace relative config file lookups with ENV variable.
* Modify gitlab-shell to not clear then environment when running
pre-receive.
* Modify gitlab-shell to write some environment variables into
the .authorized_keys file to make sure gitlab-shell reads the
correct config file.
* Log unicorn output to syslog.
I tried various ways of adding a syslog package but the bundler would
not pick them up. Please fix in a better way if possible.
* Gitlab-runner program wrapper.
This is useful to run e.g. backups etc. with the correct
environment set up.
