helmfile

Helmfile - "needs" keyword has no effect

I have been trying to make use of the keyword needs (following the doc) to control the order of installation of the releases.

Here is my helmfile:

helmDefaults:
  createNamespace: false
  timeout: 600

helmBinary: /usr/local/bin/helm

releases:
- name: dev-sjs-pg
  chart: ../helm_charts/sjs-pg
- name: dev-sjs
  chart: ../helm_charts/sjs
  needs: ['dev-sjs-pgg']

Regarding versions:

When I run helmfile sync , both releases are installed simultaneously. In particular, there is no error due to my spelling error (dev-sjs-pgg instead of dev-sjs-pg). It is like needs is just not read.

Could you help me understanding what I am doing wrong please ?

Solution

  • I tried to reproduce this. When executing helmfile --log-level=debug sync I see in the debug log:

    processing 2 groups of releases in this order:

    GROUP RELEASES
1     dev-sjs-pg
2     dev-sjs

    I also see these are deployed one after another (just a few seconds difference because I am deploying a fast nginx chart):
