List all objects from a given namespace using kubectl

Question

I would like to list all objects that are present in a specific namespace in kubernetes.

kubectl get all -n <namespace>

the above command doesn't list all available objects from the given namespace. Is there a way to list them using kubectl?

i can list all objects that i want by passing them to kubectl. but i dont want that.

kubectl -n <namespace> get deployment,rs,sts,ds,job,cronjobs -oyaml

Answer 1

First of all these following rules decide if the resource will be part of the all Category or not.

Here are the rules to add a new resource to the kubectl get all output.

• No cluster scoped resources

• No namespace admin level resources (limits, quota, policy,
  authorization rules)

• No resources that are potentially unrecoverable (secrets and pvc)

• Resources that are considered "similar" to #3 should be grouped the
  same (configmaps)

To Answer your question This is taken from rcorre's Answer

kubectl api-resources --verbs=list --namespaced -o name \
  | xargs -n 1 kubectl get --show-kind --ignore-not-found -l <label>=<value> -n <namespace>

Lastly, If you want to add a Custom Resource in all category, you need to provide these field in your CRD spec. custom-resource-definitions:categories

# categories is a list of grouped resources the custom resource belongs to.
    categories:
    - all
