- sets up a dev container that works in vscode dev containers and github codespaces - calls `local-deploy.sh` on start up to deploy opencodelists to an instance of dokku in a container - also deploys an otel-collector container so the trace messages have somewhere to go rather than filling the docker logs with http failures
- Runs most of the commands from main.yml - Needs to run the app on a different port (7001) for the smoke test because the local dokku instance is already using 7000
- This allows you to make changes to things like the Procfile or Dockerfile and then test the redeployment process. - Supports passing a branch name so you can test deploy any remote branch
- All local sqlite files were being bundled in the docker image - This was making the image 32GB and took ages - Ignoring them reduces the image to < 0.5GB

Closing as I don't think we need this older version of the proposed change any more. |

Based on the work by @StevenMaude here.
If you check out this branch you can simulate deploying production builds locally.

LOCAL_TEST_DEPLOYMENT.md.It still needs tidying up before merging, but works as-is.
Possible improvements:
local-ci-pipeline.shscript doesn't work when deploying a remote branch. This is because it relies on things in the justfile in this branch, but when deploying a remote branch it uses the justfile from that branch.
