Documentation for running Caddy in Docker

[lodi-g]

Problem I have not installed Caddy on my dev machine and do not wish to do so. However, I still want to use caddy fmt. It's easy to run it manually via Docker but doesn't leverage the full features of this extension.

Solution I wrote a super simple wrapper script to make this extension work with a dockerized Caddy. It could be interesting to add it to the documentation. It works on MacOS (and most likely on Linux, not tested).

#!/usr/bin/env bash

cat /dev/stdin | docker run --rm -i --entrypoint caddy caddy:2.6-alpine "$@"

Once the script is set up somewhere, just point caddy.executable to it and it works.

I tested it on a Remote SSH editor and it doesn't work well. Not sure why.

After reading the code about using caddy fmt and tested on my vm, i think cat /dev/stdin isn't necessary in this case.

I am tying this too:

this is my code:

cat >/usr/bin/caddy <<EOF
#!/usr/bin/env bash
# -*- coding: utf-8 -*-
podman run --rm -i docker.io/caddy:latest caddy "$@"
EOF

chmod +x /usr/bin/caddy

this will create a file reference for caddy, using this with the extension work

pwd: ${HOME}/caddytxt

inside this folder I have a Caddyfile and executing

caddy fmt --overwrite will edit the file and fix the format.
