This container is intended to ease the pain of installing alembic and it's dependencies on your host in order to run alembic migrations in a Python project.
To successfully run the migrations you should have previously created the database and initialized alembic. You achieve this with the same container:
docker container run --rm -v /path/to/dir/:/srv contre95/alembic init /srv
The Alembic migration environment would be created on the specified path.
You would like to configure the alembic.ini in order to set the database connection. (Please make sure you use 127.0.0.1 instead of localhost)
To run the migration or any other alembic command simply run:
docker container run --rm --network=host -v /alembic/migrations/env/path:/srv contre95/alembic <alembic-command>
