I'm trying to upgrade my Flagger installation using Helm from 0.12.0 to 0.15.0 and I'm getting this error:

Error: failed to create patch: merging an object in json but data type is not struct, instead is: map

Apparently this is an issue upgrading CRDs (see helm/helm#5853).

Upgrade workaround:

  • uninstall Flagger (the CRD and the canary resources will be left untouched):
helm delete flagger --purge
  • update the CRD with kubectl:
kubectl apply -f https://raw.githubusercontent.com/weaveworks/flagger/master/artifacts/flagger/crd.yaml
  • reinstall Flagger with Helm without the CRD:
helm upgrade -i flagger --set crd.create=false

This has been fixed in Helm v2.14.3, I've tested it by upgrading from Flagger 0.12.0 to 0.15.0 to 0.18.1 🎉
