I am using this chart : https://github.com/helm/charts/tree/master/stable/prometheus-mongodb-exporter
This chart requires MONGODB_URI
environment variable or mongodb.uri
populated in values.yaml
file,
Since this is a connection string I don't want to check-in that into git.
I was thinking of kubernetes secrets and provide the connection string from kubernetes secrets. I have not been able to successfully find a solution for this one.
I also tried creating another helm chart and using this one as a dependency for that chart and provide value for MONGODB_URI
from secrets.yaml
but that also didn't work because in prometheus-mongodb-exporter
chart MONGODB_URI
is defined as a required value which is then passed into secrets.yaml
file within that chart, so dependency chart never gets installed because of that.
What would be the best way of achieving this?
secret.yaml
from chart's template directory.secret
on your own, maybe named cumstom-secret
deployment.yaml
: here - name: MONGODB_URI
valueFrom:
secretKeyRef:
name: custom-secret ## {{ include "prometheus-mongodb-exporter.fullname" . }}##
key: mongodb-uri
mongodb.uri
in value.yaml
.--set
flag to overwrite the dummy value with original while installing the chart. So, your git
won't have the history.$ helm install prometheus-mongodb-exporter stable/prometheus-mongodb-exporter --set mongodb.uri=******
so I have to copy original chart when creating custom chart? it's not possible to create a custom chart with original chart added as dependency?
@AsavPatel no, by custom chart I meant, copy the chart some directory, edit it. And then deploy it from there. Just go to the chart directory and use
helm install <name> <chart-name>
. No need userepo
name likestable
