python-rasenmaeher-miniwerk's Introduction

miniwerk

Minimal KRAFTWERK amulation to be able to run a RASENMAEHER+products deployment on any VM

There are some required ENV configs check out example_env.sh for them (.env file is also supported)

Docker

For more controlled deployments and to get rid of "works on my computer" -syndrome, we always make sure our software works under docker.

It's also a quick way to get started with a standard development environment.

SSH agent forwarding

We need buildkit:

export DOCKER_BUILDKIT=1

And also the exact way for forwarding agent to running instance is different on OSX:

export DOCKER_SSHAGENT="-v /run/host-services/ssh-auth.sock:/run/host-services/ssh-auth.sock -e SSH_AUTH_SOCK=/run/host-services/ssh-auth.sock"

and Linux:

export DOCKER_SSHAGENT="-v $SSH_AUTH_SOCK:$SSH_AUTH_SOCK -e SSH_AUTH_SOCK"

Creating a development container

Build image, create container and start it:

docker build --ssh default --target devel_shell -t miniwerk:devel_shell .
docker create --name miniwerk_devel -v `pwd`":/app" -p 80:80 -it `echo $DOCKER_SSHAGENT` miniwerk:devel_shell
docker start -i miniwerk_devel

pre-commit considerations

If working in Docker instead of native env you need to run the pre-commit checks in docker too:

docker exec -i miniwerk_devel /bin/bash -c "pre-commit install"
docker exec -i miniwerk_devel /bin/bash -c "pre-commit run --all-files"

You need to have the container running, see above. Or alternatively use the docker run syntax but using the running container is faster:

docker run --rm -it -v `pwd`":/app" miniwerk:devel_shell -c "pre-commit run --all-files"

Test suite

You can use the devel shell to run py.test when doing development, for CI use the "tox" target in the Dockerfile:

docker build --ssh default --target tox -t miniwerk:tox .
docker run --rm -it -v `pwd`":/app" `echo $DOCKER_SSHAGENT` miniwerk:tox

Production docker

There's a "production" target as well for running the application, remember to change that architecture tag to arm64 if building on ARM:

docker build --ssh default --target production -t miniwerk:amd64-latest .
docker run -it --name miniwerk miniwerk:amd64-latest

Development

TLDR:

Create and activate a Python 3.11 virtualenv (assuming virtualenvwrapper):
```
mkvirtualenv -p `which python3.11` my_virtualenv
```
change to a branch:
```
git checkout -b my_branch
```
install Poetry: https://python-poetry.org/docs/#installation

Install project deps and pre-commit hooks:

poetry install
pre-commit install
pre-commit run --all-files

Ready to go.

Remember to activate your virtualenv whenever working on the repo, this is needed because pylint and mypy pre-commit hooks use the "system" python for now (because reasons).
