Multiple docker sockets?

[andyloree]

Would it be possible to add support for multiple, remote docker hosts? Instead of having to create static files, ability to support multiple docker instances via something like docker-socket-proxy would allow for a non-swarm, stand-alone docker hosts configured via labels. Homepage does this today with labels approach, via a single config file, adding entries for each docker socket: https://gethomepage.dev/v0.8.0/configs/docker/#using-docker-socket-proxy

AUTOKUMA__DOCKER__HOSTS="tcp://host_1:2375;tcp://host_2:2375" should work.

Also make sure you're on the master tag and have pulled the latest image (or use ghcr.io/bigboot/autokuma:sha-11b6c5d) for the specific build.

Thanks, mistakenly thought latest was getting tagged as the build :)

I got the latest running, but now having an issue with it not liking "tcp://" hosts, it keeps prepending "unix://" schema

# export AUTOKUMA__DOCKER__HOSTS="tcp://apps.[redacted]:2375"
# autokuma
...
WARN [kuma_client::util] Using DOCKER_HOST=unix://tcp://apps.[redacted].com:2375
WARN [autokuma::sync] Encountered error during sync: Error in the hyper legacy client: client error (Connect)

Seems like no matter what is in the env value, its putting unix:// schema on it. I tried a few different variations but no luck.

Looks like code at issue is here, hard-coded to prepend unix://

Hi,

I'm facing exact same issue and it's quite a coincidence that you were working on this at the same time. I have created PR here to fix this: https://github.com/BigBoot/AutoKuma/pull/64. I'm not a programmer and have not written Rust before. Please review/test before merging.

My Docker Swarm config file:

services:
  docker_host:
    image: ghcr.io/tecnativa/docker-socket-proxy:latest
    ports:

I get the following error:
