Editing One Quick Way To Host A WebApp (section)

==== Registry ====

Originally, I used to just build the docker images on the server itself. This was simply out of convenience. After some time, it got to be a bit of a hassle and I found myself doing the annoying thing of just writing code on the server and building the image there. Well, that's a bit dopey, but it's very easy to fix. You can run a registry container on the server and just push images to it when you're ready.

<syntaxhighlight lang="ini">
ubuntu@kant:~$ cat ~/.config/containers/systemd/registry.container
[Unit]
Description=Container Registry
After=network-online.target
Wants=network-online.target

[Container]
Image=docker.io/library/registry:2
PublishPort=5000:5000
Volume=registry-data:/var/lib/registry
AutoUpdate=registry

[Service]
Restart=always
TimeoutStartSec=900

[Install]
WantedBy=default.target
</syntaxhighlight>

That's a systemd quadlet that runs the registry. I do the usual `docker build --platform=linux/amd64 .` on my Mac and then the `docker tag registry.blahblah.com` and then `docker push` to it and it all works just like you'd expect.
