System environment setup

1. Install Docker.

2. Configure userns-remap to map container user root to a host non-root user.

3. Configure the dev station as a Docker Swarm Manager.

4. Install a Postgresql database server.

You can use the Ansible playbook provided to install PostgreSQL locally with Docker, after configuring hosts.yaml:

make environment

Python environment setup

• It requires Python 3.8+.

• Pyenv should be used to choose the right version of Python, without breaking the default Python of the Operating System.

• A Python virtual environment should be created in a .venv folder.

    pyenv install 3.8.0
    pyenv shell 3.8.0
    python -m venv .venv 
    source .venv/bin/activate`
