Summary

Builder base

• Switch builder base images to defi/ain-builder: https://github.com/DeFiCh/containers/blob/main/ain-builder/Dockerfile
• This is used to avoid re-doing the work of updating containers on each run.
  • This also often results in random errors due to Ubuntu repo timeouts. This avoids this by using a pre-warmed up base.
  • In addition, helps speed up the CI
• Note: There is no difference in how the post-base items are handled. They still go through the same dep installs - and follow the exact same procedure as they would on a fresh container.
  • This just provides it pre-warmed up, so they can be expected to take a faster path.
  • This ensure any changes that's made here are still executed, if the base deps are out of date, etc.

CI

• Fix tests failing due to incorrect init
• Enable EVM tests on master
• Cleanup workflows

make.sh

• Add PATH to ci-export-vars
• Switch to apt-get on automation.

• In addition, this also fixes defid 4.0.0.-beta1 not running with GLIBC 2.31 #2046
• Remove stale comment from docker images
