I'm trying to create a ConfigMap with ArgoCD.
I've created a volumes.yaml file as such
---
apiVersion: v1
kind: ConfigMap
metadata:
name: persistent-volumes-argo
labels:
grafana_dashboard: "1"
project: "foo"
data:
kubernetes.json: |
{{ .Files.Get "dashboards/persistent-volumes.json" | indent 4 }}
But ArgoCD doesn't seem to be able to read the data, the way a standard Helm deployment would.
I've tried adding the data directly into the ConfigMap as such
(Data omitted for brevity)
---
apiVersion: v1
kind: ConfigMap
metadata:
name: persistent-volumes-argo
labels:
grafana_dashboard: "1"
project: "foo"
data:
kubernetes.json: |

Is there a way to pass in json data when creating a ConfigMap with ArgoCD, either as a template or by dumping the data in the file?
CodePudding user response：
To create configmap with argocd and helm
apiVersion: v1
kind: ConfigMap
metadata:
name: {{ include "helm-chart.fullname" . }}-configmap
data:
config.json : |
{{ toJson .Values.configmap | indent 4 }}
and the value file should be like this, which is our JSON but converted to YAML
configmap:
json:
- rigid
- better for data interchange
yaml:
- slim and flexible
- better for configuration
object:
key: value
array:
- null_value:
- boolean: true
- integer: 1
- alias: &example aliases are like variables
- alias: *example
paragraph: >
Blank lines denote
paragraph breaks
content: |-
Or we
can auto
convert line breaks
to save space
alias: &foo
bar: baz
alias_reuse: *foo
Make sure you also set
export ARGOCD_AUTH_TOKEN="tokeh
export ARGOCD_OPTS="--grpc-web"
export ARGOCD_SERVER="argocd.example.com"
added section for the configmap
