@jit-1 lmk if you were able to setup pre-commit locally (as this isnt something the repo enforces but will be helpful to maintain code quality).

• Unable to find the package installation of pre-commit in the poetry setup
• Issue with docker '''sudo usermod -aG docker $USER'''

usermod: group 'docker' does not exist Based on closer inspection, I could not find at which step docker is being installed. Unable to use docker -v or anything to check the docker version

Maybe lets fix the docker stuff in another Pull request because I think you worked on that so Im not sure what you did there. In fact, I think there is a currently stale branch that has got some docker fixing being worked on (https://github.com/AQ-AI/openaq-engine/pull/12)

I have pushed the pre-commit addition to poetry packaging. please re-review.
