Aligning RAILS_ENV, DD_ENV, Amplify Stage, Namespace Stage in AWS Deployments

Questions

  • should RAILS_ENV == DD_ENV
  • should DD_ENV == NAMESPACE_STAGE

how do we make these decisions?

current environment

  • lower level deployed heroku apps use 'staging' as RAILS_ENV.

eight bullet versioning and release process

releases

  • semantic versioning is used
  • a branch is created for every major release, e.g. release-1.x, release-2.x, &c.
  • when ready to make a release;
    • update any changelogs and documentation with release information, commit/merge to main. ensure CI passes.
    • if backporting fixes into past releases, follow the backporting procedure from containerd, else merge main into the current release branch. e.g. main -> release-2.x.
    • checkout current release branch and update files/version with the current point release, e.g. change 'main' to 2.1.18-rc1.
      • make a release commit (e.g. with message "RELEASE 2.1.18-rc1").
  • tag the release using v as a prefix, e.g. git tag v2.1.18-rc1 && git push --tags

convert Ubuntu AMI from MBR partitioning to GPT partitioning
// the following assumes AWS nitro (e.g. t3.*, m5.*, &c) instances (which use /dev/nvme0n1 as root disk)
// "safely" switches from MBR to GPT partitioning in Ubuntu < 21.04 or other AMIS.
// Tested using gdisk 1.0.3 from 18.04 / Bionic.
// after the change, you can use >2TB root disks. either initially, or by resizing a smaller one -- in nitro and non-nitro types
