Caddy: reinvigoration of caddyserver/caddy docker image

[grooverdan]

I noticed on your main download site the options for cross compiled images are extensive. Wondering if you'd consider extending concept to bring multiarch base images to https://hub.docker.com/r/caddyserver/caddy. This would help simplify some use rather than some convoluted builds.

The below script based on github released images generates a multiarch manifest http://soaphub.org/imagehub/?q=caddy&n=danielblack&p=0 with the intent that a user would extend the image with FROM caddyserver/caddy:v1.0.1 and this would fetch the architecture image required. The caddyserver/caddy:latest is also pushed with this image and this is usually a mature release rather than a bleeding edge.

Notes:

• Windows image generation on Linux seem to fail at the base image (even with docker pull --platform windows/amd64 mcr.microsoft.com/windows/servercore) maybe need to need azure
• Arm(32) variants can use the --variant with v3 .. v8 identifiers (https://github.com/containerd/containerd/blob/master/platforms/cpuinfo.go#L99)
• Individual base images are autotagged with amd64/linux as the base system as docker push can't specify a platform.

I recommend using https://github.com/abiosoft/caddy-docker. It's maintained quite diligently by @abiosoft and is quite flexible. It's as close to an official docker image as you'll get for the time being.

Thanks for the tip. I might get around to looking cross-building there. We'll see if the outstanding PR gets merged.

We're trying to publish official images for v2, but Docker has been silent to our support emails and this forum thread: https://forums.docker.com/t/organization-name-already-exists-but-is-empty/82483

What a pity. FWIW, they have done it in the past. See openresty/docker-openresty#4. Good luck with it.

We finally got the name and are now finishing up the Docker image. @Ilyes512 would probably have an update on that!

Please provide documentation about using inside docker (like examples of Dockerfile, commands to execute, docker-compose, swarm & k8s)

I've been looking without much success to find an official docker image for caddy.

Is there perhaps an update to this thread, or direction to which is the preferred docker to use?

Thanks.

[francislavoie]

Yep! https://github.com/caddyserver/caddy-docker

There's also an open PR to add it as official image! https://github.com/docker-library/official-images/pull/7574

I'll close this now - nothing actionable left here.
