Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kustomize

  • No packaging or distribution story, which is exactly what Helm charts provide
  • Deeply nested overlays become hard to follow, and reasoning about the final output requires building it
  • No release lifecycle: nothing tracks what is installed or supports rollback the way Helm does
  • Patch syntax is fiddly for anything beyond simple field replacement

Oracle Cloud

  • The free trial gives US$300 of credit that expires when consumed or after 30 days, whichever comes first
  • The US$300 cloud credit is available only in select countries
  • Only one Oracle Cloud Free Trial or Always Free account is permitted per person
  • Accounts left idle for 30 days or more are eligible for suspension or termination as abandoned
  • Always Free NoSQL Database is restricted to the Phoenix region
  • Free Tier availability is subject to capacity limits, and the published per-service capacity figures are estimates that assume the entire credit is spent on that one service
