docker build fails

[lupino3]

Problem/Motivation

Running docker build on the current main branch generates the following errors:

Trying to install the add-on also generates the same errors, since docker build is part of the installation process.

The key part seems to be:

There is a Python version conflict.

Expected behavior

The docker container image should be built.

Actual behavior

The image is not built.

Steps to reproduce

Clone the repository and run docker build.

Proposed changes

I got it to build by patching the Python version in the Dockerfile, and I'll send a PR with this change:

diff --git a/prometheus/Dockerfile b/prometheus/Dockerfile
index 99f4800..804ac52 100755

Not sure if there is a systemic fix there: why do we have such a conflict here and how can it be avoided?

Note: I can reproduce the issue in the following environments:

• Windows dev box
• WSL environment on the same Windows dev box
• my main HA installation (HAOS on Raspberry Pi 3B+)

Note that currently the CI GitHub action is failing because of this problem: https://github.com/hassio-addons/addon-prometheus/actions/workflows/ci.yaml.

It would be useful to run CI on a daily or weekly basis to catch these conflicts as they crop up.
