Introduction

Release Automation is the cornerstone of modern Software Delivery. Well-established CI/CD pipelines are fundamental to every organization that wants to embrace DevOps/GitOps methodologies in order to achieve:

  • Frequent, rapid release cycles.
  • Fully automated deployment and rollback based on deployment strategies (Rolling Updates, Canary Releases, Blue/Green deployment).
  • Continuous-integration with automated testing.
  • More resources devoted to automated testing than manual testing.

Getting Alluxio to run on Nomad turned out to be a little more involved than I thought. One major issue I ran into quite early on in the exercise was that Nomad doesn’t yet support persistent storage natively (expected in the next release).
