The flag --recreate-pods was marked as deprecated in Helm 2 and was removed with Helm 3.

Helm suggests to either add checksums of other files which could have changed like this

      annotations:
        checksum/config: {{ include (print $.Template.BasePath "/configmap.yaml") . | sha256sum }}

or to add an annotation with a random number which forces an update on each rollout:

      annotations:
        rollme: {{ randAlphaNum 5 | quote }}
