Add extra custom labels to existing helm chart-CodePudding

I am using an existing helm chart repo https://github.com/kubecost/cost-analyzer-helm-chart

For deployment I am using custom helm chart, have created tgz of the repo and put it under my own charts/ directory and then i put my own certain templates which deploys some resources related to cost-analyzer.

I want to assign some custom labels to the resources which are coming from that tgz.

Is there something/someway that i can add custom labels to all the resources which are deployed using my custom helm chart including the resource which are from tgz.

CodePudding user response：

There is nothing built into Helm for doing that.

You can set the additionalLabels field in their Helm chart values.yaml file (there are multiple places this needs to be done).

A potential kludge could be to pull the manifests after deploying, get the name and type of every resource, and pump that into a kubectl command to label everything, for example:

HELM_RELEASE="???"
NAMESPACE="???"
LABEL="???"
helm get manifest $HELM_RELEASE -n $NAMESPACE \
  | kubectl get -n $NAMESPACE -f - \
  | grep -vE '^$|^NAME' \
  | cut -d' ' -f1 \
  | xargs -I {} kubectl label {} $LABEL
