Kubectl — List all resources in same namespace
A publication for sharing projects, ideas, codes, and new theories.
Follow up on my Kubernetes blogs about
We all know to use kubectl -n <namespace> get all to list the resources in
To get a comprehensive list of all resources, you can use the following command:
kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -n <namespace>
For example, I’d like to list all resources in namespace loki I recently installed (follow my previous blog: my Research on Grafana Loki in conjunction with Kubernetes)
you can run the command
$ kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -n loki

- statefulset.apps
This command lists all API resources that support the list operation in the specified namespace, and then retrieves instances of each resource. Obviously, some monitoring resources are CRDs
If you want to know which resources are CRDs, you can double check with
kubectl get crds
If you use the command frequently, you can set alias on it, such as, put it in ~/.bash_profile
alias kl="kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -n"
# then you can run the short command
kl loki
