Pete KeenSo I built out this whole thing to manage <a href="https://hachyderm.io/tags/k8s" class="mention hashtag" rel="nofollow noopener" target="_blank">#k8s</a> pods like a DaemonSet except with predictable templated names and an auto-generate service. Tests work, everything looks like it should work, except... it doesn't.Turns out I've been foiled by a limitation built into Metacontroller since forever: namespaced metacontrollers can't talk to cluster-scoped objects.Cool. Cool cool cool. I guess I'll just do this with a cron?

Elias ProbstAnger-inducing bullcrap of the day: projects that package their Ansible collection in a way, where the only way to use it is, to execute the included playbooks standalone.Instead of just using multiple roles within the collection - or multiple entrypoints within the role.You know, just like normal people do.This breaks every sane architectural convention and composability 🤬🤬Looking at you, <a href="https://mastodon.social/tags/kubespray" class="mention hashtag" rel="nofollow noopener" target="_blank">#kubespray</a> <a href="https://mastodon.social/tags/Kubernetes" class="mention hashtag" rel="nofollow noopener" target="_blank">#Kubernetes</a> <a href="https://mastodon.social/tags/Ansible" class="mention hashtag" rel="nofollow noopener" target="_blank">#Ansible</a> <a href="https://mastodon.social/tags/K8S" class="mention hashtag" rel="nofollow noopener" target="_blank">#K8S</a>

Tero Keski-ValkamaSo, having a home <a href="https://rukii.net/tags/k8s" class="mention hashtag" rel="nofollow noopener" target="_blank">#k8s</a> cluster something about Posgres HA has been bugging me a lot. When there's an electric blackout (this is <a href="https://rukii.net/tags/Spain" class="mention hashtag" rel="nofollow noopener" target="_blank">#Spain</a> after all), all the pods go down. But what happens with Postgres is that the replicas go into a process to sync and elect a new master, and this takes time.Meanwhile, the pgpool will give successful database connections to apps in pods, but only read-only.What happens with an app like <a href="https://rukii.net/tags/Matrix" class="mention hashtag" rel="nofollow noopener" target="_blank">#Matrix</a> <a href="https://rukii.net/tags/Synapse" class="mention hashtag" rel="nofollow noopener" target="_blank">#Synapse</a> is that I think it gets database connections in a pool at start-up, and as it succeeds, it just continues. However, when it actually tries to make updates and inserts, it will get errors, but now it will only log them; they aren't fatal. Or would log them unless the logs were by default off because of privacy and security.The initial read-only database connections are never upgraded to read-write because the application doesn't expect this kind of a failure, even when the new master is chosen.Meanwhile the Matrix server continues in a highly degraded mode without being able to persist messages sent. It will only be able to relay them to currently connected online clients. This leads to users getting diverging views to the messages on channels.I solved this by adding an initContainer to check for read-write connection to Postgres before the Synapse pod start-up, but it's a hack.<a href="https://rukii.net/tags/SelfHosting" class="mention hashtag" rel="nofollow noopener" target="_blank">#SelfHosting</a>
