Configurable devevelopment port & documentation updates

[spwoodcock]

Problem

• The docker compose setup for development uses Traefik on port 80.
• On many machines port 80 is not an option: either in use, or not available in rootless mode.
• The container names are also a mix of conventions: two being automatically generated, two being manually specified.
• The development setup guide is also missing a few things to get started easily.

Solution

• Added a TM_DEV_PORT variable to the dotenv options, so the port can be configured.
• Updated all containers to have consistent names. I prepended tm- to prevent conflict with other tools that may have containers named backend and frontend.
• Updated the development setup guide:
  • Info on running via docker.
  • How to set up OSM OAuth creds.

Context

• @robsavoye was having some issues setting up Tasking Manager for testing.
• I realised there isn't actually a guide for running the entire stack in Docker during development, which I assume some people would want to do.

2024-02-02 15:35 Update/Edit:

• I removed info about using pep582, as this was blocked by the python steering comity (😢)
• I noticed an unpinned pdm version during functional tests in CI. I pinned to the same as others in the repo.
• Clarified info about running backend api only.

There are two different docs on using docker with TM, but since docker wasn't working, I could update and merge the two docs.

[spwoodcock]

Where is the second doc? I couldn't find it.

I found a guide for installing TM via docker for deployment, but no complete guide for running via docker during development.

[robsavoye]

one is in docs-old, the other in in an old PR from Outreachy last year. I'm trying to get rid of docs-old by updating the docs, and moving them all to docs. Once I can get docker to work, I can merge and update a single doc.

[robsavoye]

The old one I was planning to merge in is here: #5621. You're welcome to update a doc on docker usage for TM. :-)

[spwoodcock]

Looks fine to me - that one is for deployment specifically though.

I know they are similar, but we need a doc for how to deploy, and a doc for how to develop using docker.

[robsavoye]

For a doc on docker, I was thinking about a simple howto user guide. Basically an interested contributor should be able to clone the TM git repo, run docker-compose, and try TM in a self-hosted environment. I do this all the time when evaluating other projects, and if it doesn't work out of the box, that ends the evaluation most of the time.

To do that I think we should just update the example.env to use defaults for the docker based setup.

Then change the port binded to traefik by default to any >1024.

After that a user could simply:

git clone https://github.com/hotosm/tasking-manager

cp example.env tasking-manager.env

docker compose up -d

I like making it really easy for people to download and evaluate TM locally using docker.

I will make another PR (next week) updating as above & adding some info to the docs then 👍
