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.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

I use homepage and pretty happy with it. “Drag and drop configuration, no yaml” actually put me off.

I wish we would all start switching over to JSON for configuration files. It's so much easier to parse, and you can't screw it up with too many spaces or not enough.

I used to think that until I figured out yaml and now yaml isn't so bad.

It helps that text editors know what yaml is now so insert spaces when you hit tab etc

My biggest gripe with yaml (especially in docker-compose files) is that l, for me at least, it is absolutely not clear when I need to add dahes (-) in front of multiple entries and when it's just linebreaks.
And there are no easy accessible docker-compose validators...

Try the yaml language server by red hat, it comes with a docker compose validator.

But in general, off the top of my head, dashes = list. No dashes is a dictionary.

So this is a list:

thing:
    - 1
    - 2

And this is a dictionary:

dict:
    key1: value1
    key2: value2

And then when they can be combined into a list of dictionaries.

listofdicts:
    - key1dict1: value1dict1
    - key1dict2: value1dict2
      key2dict2: value2dict2

And then abother thing to note is that yaml wilL convert things into a string. So if you have ports 8080:80, this will be converted into a string, which is a clue that this is a string in a list, rather than a dictionary.
