Docker Image

pre

A postgreSQL db is running and reachable from within the contianer. I use postgresapp for example. https://postgresapp.com/documentation/

local build

version=0.0.6; docker build -t normansutorius/course:$version -f web.Dockerfile .

run it local

After you have build the image you can run course.

export DATABASE_URL=postgres://$(whoami)@host.docker.internal/postgres
version=0.0.6; docker run -it --network="host" -e DATABASE_URL normansutorius/course:$version

publish to dockerhub

docker push normansutorius/course

debug

If something went wrong with the database string for example you can overwrite the start command like this

version=0.0.6; docker run --entrypoint "/bin/bash" -it --network="host" -e DATABASE_URL normansutorius/course:$version

And you are able to debug if all the envs variables are set with the right values.
