Release Procedures

Some Rules

  • No releases after hours unless previously negotiated
  • Reponsible parties need to be present during the release
    • ie, Developer and Ops
  • Different systems have different release requirements
    • All have dependencies
    • Need to know roll back procedure
    • And, how to know if a roll back is necessary
  • The release may have ‘other‘ tasks. These should be documented and have been previously tested
    • Any env settings, configuration setting changes
    • Database changes
    • Systems that need to be stopped and started as part of the release
    • The ‘recipe‘ should be published
    • The ‘recipe‘ should have been followed in a ‘testing/staging‘ environment

Source Control

  • Use Git Flow
  • Releases are from release/VERSION_NUMBER branches
  • All code should be reviewed if necessary and merged to ‘develop‘ prior to release
    • ie, releases are branched from a stable state
  • Releases are numbered with a x.x.x format
    • Each release should increment intelligently
    • If any confusion get it sorted out ahead of time
  • DevOps will deploy the branch unless previously negotiated
