Running the API outside of docker

For faster development and debugging you might want to run just the python API part on your local system instead of in a docker container. This is described in https://github.com/SUNET/cnaas-nms README

The docker image runs debian 10 which uses Python3.7.3. If your system python is not using this version you might want to use pyenv:

apt-get/dnf install pyenv
pyenv virtualenv 3.7.3 cnaas373
cd cnaas-nms/
cp etc/db_config.yml.sample /etc/cnaas-nms/db_config.yml
pyenv local cnaas373
python3 -m pip install -r requirements.txt
cd src/
python3 -m cnaas_nms.run

You will need to have postgres and redis running to be able to start the API. You can start just those containers with:

cd docker/
docker-compose up --no-deps -d cnaas_postgres
docker-compose up --no-deps -d cnaas_redis
