List all the kubernetes resources related to a helm deployment or chart

Question

I deployed a helm chart using helm install and after this I want to see if the pods/services/cms related to just this deployment have come up or failed. Is there a way to see this?

Using kubectl get pods and greping for the name works but it does not show the services and other resources that got deployed when this helm chart is deployed.

Answer 1

If you are using Helm3:

To list all resources managed by the helm, use label selector with label app.kubernetes.io/managed-by=Helm:

$ kubectl get all --all-namespaces -l='app.kubernetes.io/managed-by=Helm'

To list all resources managed by the helm and part of a specific release: (edit release-name)

kubectl get all --all-namespaces -l='app.kubernetes.io/managed-by=Helm,app.kubernetes.io/instance=release-name'

Update:

Labels key may vary over time, follow the official documentation for the latest labels.

Answer 2

helm get manifest RELEASE_NAME
helm get all RELEASE_NAME

https://helm.sh/docs/helm/helm_get_manifest/

Answer 3

I couldn't find anywhere that gave me what I wanted, so I wrote this one-liner using yq. It prints out all objects in Kind/name format. You might get some blank space if any manifests are nothing but comments.

helm get manifest $RELEASE_NAME | yq -N eval '[.kind, .metadata.name] | join("/")' - | sort
