Add docker documentation

[Arcelone]

Hi everyone,
I've found myself needing to create a local Mastodon instance for a Lab (something that's at test/demo level).
First of all, I browsed the documentation and the official repository and I saw that the debate on the need / desire to add documentation for docker.
However, as I haven't found a satisfactory tutorial or alternative on the Internet, I've taken the liberty of making a functional version, as detailed as possible, of what I'd like to find in the official documentation.
I'm sure it's not perfect, but if anyone would like to add or modify it, please don't hesitate.

PS: I didn't know what value to enter for "Weight", please feel free to modify it.

This will (at least partially) resolve these issues :

• resolve Add Docker setup to official documentation #1547
• resolve Documentation on using the provided docker image #770
• resolve Specify and issue a more container-centric approach for deployment (in documentation) #793

Can anyone review my PR or at least give me some areas for improvement. 😃

??? Insult, really? I see the community is benevolent. So why the thumbs-up?

Nevermind. It was to dump developers to look at it. It's not an insult. I agree with the content.

Ha ok mb, I did check the meaning, but I couldn't find any positive meaning.

Wow, I'm sorry that this slipped under my radar. I'll try to take a look within the next 10 days (I'm travelling so I don't want to commit to anything sooner, but I'm now paying attention!)

• I updated my last message with some additional information.
• Did a rebase
• After some reading of related issues the documentation was never push to main due to a very opinionated point of view of only one people.
