[ChatLSE] Deployment Procedure

[Mayazure]

This is a follow-up of issue #40

For Rizzie server and services

• Create a chatlse group on the server and add relevant users to the group.
• Create folders to store project data, including docker data and static files for frontend app. Add permission to chatlse group.
• Recreate the Postgres and Ollama container using the new data folders.
• Create a new production instance of Postgres container. Set a special PORT number for this instance. The previous instance with default PORT number 5432 should be used as the testing instance.
• Write a docker-compose file to manage all services

For FastAPI APP

• Rewrite pyproject.toml and requirement.txt to lock dependencies.
• Figure out how to setup environment variables for deployment (write a start script)

For documentation

• Data location of Ollama and Postgres
• How to build installable Python package of the FastAPI APP
• How to build static files for frontend app
• How/where to upload built package and files to Rizzie

Testing environment

• We should also create a testing environment for the entire setup.

Ollama configurations

Check this: ollama/ollama#2146

• We need to figure out how to keep model in memory when using Ollama.

Here are some suggestions for differentiating test vs demo environments.

We can establish as a convention that:

• Every time we push to main, this means we want the test application to be updated.
• Every time we push a new tag (ideally from main), then this signals that we want the demo application to be updated

💡 As a good practice, check with the project leader + team members if a rebuild (e.g., because of a new schema) or update of the database is required. If the answer is yes, figure out what scripts to run or who will update the DB.

I've just got an interesting idea to setup a lightweight git server (e.g. gitea) on Rizzie. So we can create a mirror repo and add it as an extra git remote to our project. So whenever we push to main, we shall also push to Rizzie's git repo, which will then trigger an action to automatically update the server setup.

This could be an experiment to test out in the future.
