official deployment executed

Planned scope

Project Name (link)Overall description of the project's increment in the particular release
  • Dependent on: projects, on which this increment relay on
  • Affect: projects which depend on this increment


  1. Releases MUST have a web/wiki page that explains exactly what is in the release
    1. The page SHOULD be automatically generated if at all possible
  2. Releases MUST be in the form of docker images stored in DockerHub
    1. Releases MUST be architected as microservices and be Kubernetes compatible
  3. Releases MUST have a regular cadence
    1. Ideally releases WOULD happen every month
    2. The minimum cadence velocity MUST be 3 months, not 6 months
  4. Releases MUST have some form of labels, tags, or branching scheme that allows for mapping included features and bug fixes into a CHANGELOG and RELEASE NOTES
    1. See #1 above
    2. The scheme MUST be documented here in the Wiki
  5. There MUST be a variety of release types for various purposes to be determined; a starting point might be:
    1. Experimental releases for nightly or high interval testing looking for build breakages
      1. Lightly tested builds
    2. Stable regular builds for doing downstream integration testing into commercial distributions
      1. Standard testing
    3. Production builds that can be used for official releases
      1. Extensive scalability and performance testing (as possible)
  6. SHOULD develop a scheme for LTS builds based on production builds (above)
    1. QUESTION: what does an LTS build mean for an open source project that has no official support?
  • No labels
