PR Summary

• Introduction of a new GitHub Actions workflow

  • A new system process has been added which enables the automatic creation and updates of our software 'containers', a technology we use to package and deploy our software more easily. This process specifically applies to any updates labeled with "backend".
  • These improvements include steps for preparing the software building environment, connecting to the registry that hosts our software containers, determining the version name, and building/updating the software container for our backend system.
  • Every time a backend system update is made, an image of the software 'container' is stored, labeled with the specific version as well as a designation as the 'latest' version.

• Redundant command in the backend code

  • A particular comment in the backend source code which is meant to trigger our automatic testing and integration pipeline is now appearing twice, which is likely unintentional.
