Just migrated this #Mastodon server's #DockerCompose setup from #DockerDesktop to #Colima. (Also migrated #CalibreWeb.) On an 8 GB RAM M2 #Mac mini with 8 cores, you need all the memory and CPU savings you can get.

https://PhoenixTrap.com #blog post to come, because I ran into #database file permission problems with the #Docker Hardened Image for #PostgeSQL 17 and had to switch to the upstream official image.

Hosting 100 Linux dev environments on one VM using LXC

#nix people and / or #docker people and possibly also #kubernetes people - I'm having a think in my professional life about the problem of local environments on different OSes (Win / Mac / Linux) and a relatively junior team. The problem is broadly that someone picks up a project and struggles to get the stuff installed for it. One of the problems there is of 'needing' things like DBs setup - which I'm slowly moving to mock services (eg, an API with a mock DB that has training data in it).

My proposition is that Nix may solve the local environment problem - a flake on one computer should work the same on the next. This hasn't been the case with docker (for reasons I've yet to ascertain) and while (eg) localenv does some of the work there's still friction and I really like the idea of a single declarative file that does all the work of paralysing local environments _without_ faffing about with system-level installs (which is true for Node projects and Python projects which are pinned to specific versions of each).

The knock-on question is about CICD - whether or not a flake can do the work of pinning software versions for deployment and also the running of software (which docker and our cloud provider currently handles). I suspect that if Nix can't do that work then we'll need to stick with docker containers. Which in my head is muddying local dev with deployment config, which I don't like.

Thoughts appreciated #developers #devops

When Kubernetes starts throwing terms like Pods, Services, and Ingress at you, this cheat sheet helps you quickly translate the jargon into “what actually does what” so you can reason about your cluster instead of memorizing definitions 😎👇

We did the next step at clj-threats. With the new release we now separated the common knowledge from project specific part.

https://repo.prod.meissa.de/meissa/forgejo-threats

As you might see, you can now define project specific attacks and create project specific rules to apply them.

The common knowledge might be collected in the clj-threats library.
