I am new to Helm and see Helm chart values.yml with entries like:
extraEmptyDirMounts: []
# - name: provisioning-notifiers
# mountPath: /etc/grafana/provisioning/notifiers
I can't for the life of me figure out how to pass that in through the Helm overrides in the format of:
spec:
source:
helm:
parameters:
- name: extraEmptyDirMounts
value: ???
I've Googled around and am yet to find a clear example of this since it seems pretty common.
Somehow, this array of objects is supposed to be encoded in the single value parameter.
Argo CD supports passing in structured Helm values, either as a YAML object or as an encoded string. I'd use valuesObject:
over parameters:
here.
spec:
source:
helm:
valuesObject:
extraEmptyDirMounts:
- name: provisioning-notifiers
mountPath: /etc/grafana/provisioning/notifiers
parameters:
replicates the helm install --set
syntax. This is a little bit unusual format, and you can't effectively use it to provide an array of nested objects (it's possible but rather unpleasant).
