Docker Compose: how to wait for the MySQL server container to be ready?
python:3.10.5-slim-buster is a Debian GNU/Linux 10 (buster). Follow the Debian package link given by wait-for-it, we'll eventually find this link https://packages.debian.org/source/oldoldstable/wait-for-it, I downloaded the wait-for-it_0.0~git20160501.orig.tar.gz file and extracted wait-for-it.sh out to the project root directory where setup.py, app.py, .dockerignore, Dockerfile and docker-compose.yml are.

How to disable nginx DNS check?
I haven’t done it, but maybe you can use something like this in an ExecStartPre on the nginx systemd service, or if that doesnt work, as a separate service that nginx’s systemd service starts after

How to deploy postgres db with go in docker-compose?
When start to build docker-compose, it tried to connect db first, but it seems that db didn't become reachable yet. Even added wait-for-it doesn't work.

5/28 TIL: Docker Compose, Volumes, cURL
executes 'wait-for-it.sh' to wait on the availability of port 3306 before running 'air'--using wait-for-it.sh is just an example and this shell script has to be installed as part of the Dockerfilehttps://github.com/vishnubob/wait-for-it

Compose service that depends on a service from another compose
Yeah dockerize seems to achieve your second suggestion, someone also suggested my wait-for-it https://github.com/vishnubob/wait-for-it which seems to be similar but a bit more popular and also used in the official documentation https://docs.docker.com/compose/startup-order/ I think I'll go this route, the first option doesn't quite match what I need as all compose aren't necessarily to be started simultaneously.

How to make Django fail if it cannot connect to Redis?
Can't you use something like this? : https://github.com/vishnubob/wait-for-it . Essentially wait until you can ping redis port and then run wsgi runserver for django. However, are you sure that you can resolve redis host on swarm? Redis starts so fast that it makes me think it might be something else.

Colima k8s nix setup
What about the docker-cli? colima also ships with a docker-compatible cli to interact with containerd called nerdctl. We can execute the same docker cli commands like:
- Nerdctl v2 Beta

Nginx Unit – Universal web app server
Using nerdctl: https://github.com/containerd/nerdctl
I'd really disagree that compose files are somehow one-shot, or blindly modified. To the contrary, really, we have them checked in with the source code. Upon deployment to the cluster, the (running) services will be intelligently updated or replaced (in a rolling manner, causing zero downtime). LXC might be more elegant, but I have no idea what simple, file-based format I could use to let engineers describe the environment their app should run in without compose.
I need something that even junior devs can start up with a single command, that can be placed in the VCS along with the code, and that will not require deep Linux knowledge to get running. Open for suggestions here, really.

Jenkins Agents On Kubernetes
Now since Kubernetes works off of containerd I'll be taking a different approach on handling container builds by using nerdctl and the buildkit that comes bundled with it. I'll do this on the amd64 control plane node since it's beefier than my Raspberry Pi workers for handling builds and build related services. Go ahead and download and unpack the latest nerdctl release as of writing (make sure to check the release page in case there's a new one):

Going through a Kubernetes training with autogenerated captions and about half are coming up like this.
That's why nerdctl, their cli binary, is so well named.

Python + containerd? Who might be interested?
Well, it is indeed a good option. However, containerd is a good alternative that is growing even among developers. Please see: https://github.com/containerd/nerdctl

How to own your own Docker Registry address

DockerHub replacement stratagy and options
nerdctl supports IPFS for both image pulling and pushing, including encrypted images and eStargz lazy pulling. For building, the current method is a locally hosted translator so that the traditional pulls can be converted to work over IPFS. They even have docs on running it on k8s node, though if my reading is correct this isn't exactly a cloud native approach (running systemd services on each node...).
