Upgrade indy-test-automation to support Ubuntu 22.04

[WadeBarnes]

Indy Node is being upgraded to support Ubuntu 22.04. To support the testing and release process for indy-node, which integrates indy-test-automation to perform all of the functional testing, indy-test-automation needs to be updated to run the nodes using Ubuntu 22.04 containers.

There are two containers involved in the testing:

• Client
  • The container that executes the tests which remotely spin up and control the nodes and execute the tests against the nodes.
  • This is a docker in docker container, which is build using the teracyhq/docker-files GitHub repo. The repo has not been maintained in a while and the Ubuntu dockerfile only supports Ubuntu 20.04. The upgrade should consider a replacement for this container.
  • This container does not need to be running the same OS version used for the nodes, however for consistency it would be advisable.
• Node
  • The container on which the indy-node code under test is deployed.
  • This container utilizes a container supporting systemd to accurately replicate an actual Ubuntu server.
  • The source for the container is maintained in the fauust/docker-systemd GitHub repo, and images for Ubuntu 22.04 and even 24.04 can be found in the GHCR (https://github.com/fauust/docker-systemd/pkgs/container/docker-systemd) and DockerHub (https://hub.docker.com/r/fauust/docker-systemd).

Upgrading indy-test-automation involves:

• Updating the Node container on which indy-node will be installed to the expected version of Ubuntu the code will be running - 22.04 in this case. It would be advisable to make this configurable.
• Upgrading the Client container on which the tests will run.
• Updating the tests as needed to support the newer version of Python running on that container.
• Updating and refining workflows as needed.
• Updating the integration with the indy-node workflows as needed.

An ubuntu-22.04 branch has been created in this repo for the work.
