Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

Thank you so much this is very helpful, I'll definitely be taking a run at it with all of this advice in mind this week. When you mention running the whole thing as a single stack does that mean getting all of it running inside a single docker container such that it only takes the 1 docker run command? Is it a requirement to get them able to talk or just a more elegant way to have the entirety of the server running in a singular container instead of spread across several?
A stack is a group of containers that were all started together via a docker-compose.yml file. You can name the stack and have all of the containers dropped down below it. Compose is simply a straightforward way to ensure your containers all boot with the same parameters each time.
Instead of needing to remember all of the various arguments for each container, you simply note them in the compose file and run that. Docker Compose reads the file and runs the containers with the various arguments.
Moving from docker to docker-compose is the single largest ease-of-use change I made in my setup. If you want some help in how to use it, I can post a quick example and some instructions on setting it up. You would use
cd [directory with your docker-compose.yml]
to select the proper directory, thendocker-compose up -d
to run the compose file.Updating would be
docker-compose down
to stop the stack,docker-compose pull
to pull updated images,docker-compose up -d
to start your stack again, thendocker image prune -f
to delete the old (now outdated and unused) images.
