  • I’ll try that, but since I haven’t been able to find any related issues I’m pretty sure it’s a configuration error on my part. Hehe the regretfully long post. Next step will probably be to open an issue on authentik’s GitHub but since I think it’s a pebkac I would prefer not to waste their time.

Hello self hosters! I am hoping some of you wizards can help me troubleshoot my setup with authentik and traefik.

First about my setup. I have a synology nas that is running a docker compose stack. Synology is notoriously bad at keeping their docker version fresh, but hopefully that isn’t relevant to this issue. I’m running traefik for reverse proxy, and authentik for auth. In authentik land I’ve split the outpost work into its own container, named authentikproxy. Any request to a service with the authentik-basic@file or authentik@file middleware labels applied should be routed through the authentikproxy service for auth. If it detects that one isn’t authed, it will in turn send you to the authentik frontend for SSO.

The issue is that authentik randomly stops working for random routes, or randomly fails to start working for random routes. Every time this happens I need to restart my authentikproxy and traefik containers over and over until it randomly decides to work for all my routes. When this happens I am just sent straight to the app unauthenticated. I’ll have to either input http basic credentials or use the app’s login page, whichever it has. I have found nothing in the logs after months of this going on, neither authentik nor traefik seem to be aware that anything is amiss.

I suspect the issue is to do with the docker networks but that’s honestly just a hunch.

My docker-compose file is hundreds of lines long, so I’ve stripped environment and volume info while preserving traefik labels to try to keep the info more or less concise. It is certainly still too much info but I did not want to accidentally delete something crucial. Here follows my setup.

  • If you want to do this, what you probably want is to pump your logs into a log drain, something like betterstack is good. They then allow you to set up discrepancy thresholds and can send you emails when something seems to be out of the ordinary. There’s probably a self hosted thing that works the same way but I’ve never found a simple setup. You can do the whole Prometheus, influxdb, grafana setup but imo it’s too much work, and then you still have to set up email smtp separate from that.

  • That would fill the same role as watchtower I guess? I’ve previously tried to have a look at having portainer manage the docker compose stack that it’s running inside but at least back then it seemed to be a dead end and not really what portainer is meant to do. I’m not interested in moving away from docker compose at this time.

  • I’d be a bit concerned with having the git repo also be hosted on the machine itself. If the drives break it’s all gone. I could of course have two remotes but then pushing changes still becomes a multi step procedure.

Hello nerds! I’m hosting a lot of things on my home lab using docker compose. I have a private repo in GitHub for the config files. This is working fine for me, but every time I want to make a change I have to push the changes, then ssh to the lab, pull the changes, and run docker compose up. This is of course working fine, but I want to automate it. Does anyone have a similar setup and know of a good tool? I know I could use watchtower to update existing images, but this is more for if I change a setting or add a new service.

I’ve considered roughly four approaches.

  1. A new container that mounts the whole running directory and the docker socket. It will register a webhook in GitHub to receive notifications when I push to the repo, run git pull and docker up. My worries here are the usual dind gotchas.

  2. Same as 1, but don’t mount anything, instead ssh from container to host and run the steps there. This solves any dind issues, but I don’t love giving the container an ssh key to the host.

  3. Have a service running on the host outside of docker. This is probably the correct approach, but very annoying since my host is a Synology nas and it doesn’t have systemd or anything like that afaik.

  4. Have a GitHub action ssh to the machine and do the steps. Honestly the easiest way but I would prefer to not open ssh to the internet.

Any feedback or tips are much appreciated. I don’t feel like any of my options are very good and I feel like I am probably missing something obvious.

  • You should definitely figure out some infra as code system now while it’s manageable. Normally I’d recommend docker-compose as it’s very easy to learn and has a huge ecosystem, but since you’re using proxmox you might need to look at ansible like the other commenter said. Having IaC with git makes it so much easier to test new stuff, roll changes back, and all that good stuff, in addition to solving your original problem of forgetting what is running where.

    Just find the simplest IaC solution possible. Unless you are gunning for a job in infrastructure you don’t need to go into kubernetes or terraform or anything like that, you just need something reproducible that you can easily understand and modify.

  • Thought you were OP for a second there, as they were talking about composability. Whether it’s dependency injection or not depends on what shape your parameters take. If you’re doing functional programming and you’re passing handlers and connections etc. as params, that’s dependency injection. If you’re only passing strings and objects and such and the function has to do a bunch of logic to decide how to handle its params, that’s not dependency injection.

  • You’re gonna have a tough time talking to others about your code if you don’t agree on common terminology. Function invocation is just function invocation, it doesn’t say anything about the form of the parameters or composition. Dependency injection is a well known and commonly understood method of facilitating decoupling and composition by passing a function’s dependencies as parameters. From your comments you’re talking about the second, but refusing the name, for… reasons?
