POC automated updates

Setup

1. Create venv python3 -m venv ./venv
2. Install dependencies venv/bin/pip install -r requirements.txt

Update dependency file

venv/bin/pip3 freeze > requirements.txt

Execute

venv/bin/python3 executable/linux_updating.py executable/config.yml --create-test-env --destroy-test

Flow

Need 3 files:

Updating Linux

There are two modes(prod & test mode) (for poc reasons just implement the test mode)

• prod mode will have more features like backup/rollback...

• Create tmp test env

• Use existing ansible roles to provision env

• Now the state of the tmp test env, should be the same as the prod env

• Get running systemd services from prod and test env and compare?

• Anyways definitly get running systemd services from test env

• Check health of tmp test env with prometheus alertmanager

• Execute upgrade (Where does this code lays? is it in infra_config? an own branch?)

• Execute dist upgrade

• Get running systemd services and compare with list before update, if it does not match, show the difference
