ConvoStack Backend Dockerfile

Please find an reference Dockerfile that works with the ConvoStack backend below. It is also compatible with Fly.io.

Please note that you must set your env vars outside the Docker image.

Reference .dockerignore

The Dockerfile is important, but it's almost equally as important to exclude certain files from your Docker image:

# If you use SQLite for development, ensure that you're ignoring the *.db* files
sqlite-storage/*.db*
# If you are using dotenv in development for managing env vars, be sure to exclude these!
# They have no place in a Docker image and are a great way to accidentally leak secrets.
*.env
# Ignore the backend dist files. We want Docker to rebuild these during the image creation process.
dist/
