Learning and adding cd.yaml

Today I spent some time working on my CD pipeline better for ProsteZapisy. It took me some time. I was so focus on adding more code to main app that I neglected CD/CI pipelines.

This was basic one: I push code to master, GitHub Actions connects to my server over SSH, pulls the newest code, rebuilds the API Docker container, and restarts it.

   push to master
   → GitHub Actions starts
   → SSH into server
   → git pull
   → docker compose up -d --build api
 

I learned couple of things. I also learned why it is better to pin GitHub Actions versions, for example:

   appleboy/ssh-action@v1.2.5
 

instead of using:

   appleboy/ssh-action@master
 

because master can change in the future and break the pipeline without me changing anything. Small but useful information.
