Kubernetes: print namespace in helm status output

9/24/2019

In the output of helm status mychart, it show NAMESPACE in which chart is deployed that is NAMESPACE: default.

#=> helm status mychart
LAST DEPLOYED: Tue Sep 24 21:32:45 2019
NAMESPACE: default
STATUS: DEPLOYED
==> v1/Pod(related)
NAME                                     READY  STATUS   RESTARTS  AGE
nginx-web-stg-55f55958-v2cxm             0/1    Pending  0         28m
tomcat-api-stg-6d54498fdd-cqctr          1/1    Running  0         28m

and if I run kubectl get all -A, It show NAMESPACE along with resouces name-

#=> kubectl get all -A
NAMESPACE           NAME                             READY    STATUS  RESTARTS  AGE
nginx         pod/nginx-web-stg-55f55958-v2cxm        0/1     Pending    0      20m
tomcat        pod/tomcat-api-stg-6d54498fdd-cqctr     1/1     Running    0      20m

In the Kubectl output, column for NAMESPACE is included in output but not in helm status mychart. I wish to print resources along with NAMESPACE in helm status mychart output.

Helm helps you manage Kubernetes applications — Helm Charts help you define, install, and upgrade even the most complex Kubernetes application.

The Kubernetes command-line tool, kubectl, allows you to run commands against Kubernetes clusters. You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs.

According to issue simply execute:

$ kubectl api-resources -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -l release=your-chart-name --all-namespaces

Sample output:

user@home:~$ kubectl api-resources  -o name   | xargs -n 1 kubectl get --show-kind --ignore-not-found -l release=terrific-ferret --all-namespaces

We are using kubectl api-resources to list all supported resource types along with their shortnames.

Useful information you can find here: api-resources.

The output formats of kubectl and helm are completely unrelated. I'm not aware that you can modify the output of helm status in any way to make it display the namespace with each resource.
