## Problem
The `lint-release-pr` workflow run for
https://github.com/neondatabase/neon/pull/11763 failed, because the new
action did not match the lint.
## Summary of changes
Include time in expected merge message regex.
## Problem
We've started sending slack notifications for failed container image
pushes that are being retried. There are more messages coming in than
expected, so clicking through the link to see what image failed is
happening more often than we hoped.
## Summary of changes
- Make slack notifications clearer, including whether the job succeeded
and what retries have happened.
- Log failures/retries in step more clearly, so that you can easily see
when something fails.
## Problem
We had a problem with https://github.com/neondatabase/neon/pull/11413
having e2e tests failing, because an e2e test
(8d271bed47)
depended on an unreleased pageserver fix
(0ee5bfa2fc).
This came up because neon release CI runs against the most recent
releases of the other components, but cloud e2e tests run against
latest, which is tagged from main.
## Summary of changes
Add an additional `released` tag for released versions.
## Alternative to consider
We could (and maybe should) instead switch to `latest` being used for
released versions and `main` being used where we use `latest` right now.
That'd also mean we don't have to adjust the CI in the cloud repo.
## Problem
We've seen quite a few CI failures related to pushes to docker hub
failing with weird error messages that indicate maybe docker hub is just
not reliable.
## Summary of changes
Retry container image pushing up to 10 times, and send a slack message
if we had to retry, regardless of the job succeeding or not.
## Problem
Docker Hub has new rate limits coming up, and to avoid problems coming
with those we're switching to GHCR.
## Summary of changes
- Push images to GHCR initially and distribute them from there
- Use images from GHCR in docker-compose
## Problem
A small adjustment in #11061 broke the lint-release-pr.sh script, and
the new version was neither tested nor linted. This has been done now,
the script is once again tested and passing `shellcheck`.
## Summary of changes
Add missing `el` of `elif` condition chain.
## Problem
When we release our components, we perform builds in the release PR,
then test the components, then merge the PR, and then build everything
*again*, run tests *again*, and only then start deployments.
To speed things up, we want to perform builds and run tests in the PR,
and start deployments using the existing artifacts from the release PR.
To make that possible, we need to have both CI pipelines running on the
same commit hash, which requires fast forwarding release. That only
works, if we have a commit in the PR that has the current release branch
state as an ancestor.
## Summary of changes
- Changes to release PR creation:
- Remove templates and automatic bodies for release PRs. The previous
template wasn't used anymore, and the automatic body we created in the
pipeline didn't contain any useful content anymore after the changees
here.
- Make it possible to select the source branch. For releases that aren't
cut from `main`, like https://github.com/neondatabase/neon/pull/11051,
we need a way to trigger the new flow from a different branch.
- Determine `release-branch` automatically from the component name
instead of passing that as well.
- Changes to the merge queue job:
- Rename `get-changed-files` to `meta` in preparation of additional data
being fetched as part of that job
- Fail the merge queue if we're trying to merge into a branch other than
main - this is to prevent non-fast-forward merges.
- Label PRs to branches other than main as `fast-forward`, to trigger
the fast-forward job
- Add a fast-forward job that can be triggered with the `fast-forward`
label that performs a fast-forward merge. This only happens if the PR
has `mergeable_state == clean`, so CI having passed.
- Build and Test on releases now skips building images, skips testing
images and skips triggering e2e tests. We add new tags to the images
from the release PR to tag them as release images, and we push them to
the prod registries.
## Problem
Release CI is slow, because we're doing unnecessary work, for example
building compute images on storage releases and vice versa.
## Summary of changes
- Extract tag generation into reusable workflow and extend it with
fetching of previous component releases
- Don't build neon images on compute releases and don't build compute
images on proxy and storage releases
- Reuse images from previous releases for tests on branches where we
don't build those images
## Open questions
- We differentiate between `TAG` and `COMPUTE_TAG` in a few places, but
we don't differentiate between storage and proxy releases. Since they
use the same image, this will continue to work, but I'm not sure this is
what we want.
