[considering] Minimize dockerfiles

[DeanAyalon]

Current dockerfile variations

Ubuntu20 AMD64

• 19.6.4.402 (FROM amd64/ubuntu:20.04)

  FROM amd64/ubuntu:20.04

  Ubuntu22 AMD64

• 20.3.2.205
• 21.0.1.51

  FROM amd64/ubuntu:22.04
  # Some package updates

Ubuntu22 ARM64

• 20.3.2.205
• 21.0.1.51 (TODO - No difference expected)

  FROM arm64v8/ubuntu:22.04
  # Same package updates as u22amd64

Consideration

Split files into dockerfile.u20 and dockerfile.u22. Within prep/installations/fms, put the dockerfiles and all .deb packages the user may install

Obstacles

• [ ] Using the correct dockerfile for the correct FMS version
  • [ ] Check if FMS19 can be installed on Ubuntu22.04
• [ ] ARM vs AMD
  • [ ] Check if ubuntu can be used instead of amd64/ubuntu and arm64v8/ubuntu
• [ ] Future updates may become backward incompatible, which would require re-splitting the dockerfiles
  • [ ] I guess we cross that bridge when we get to it
