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

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

Perhaps you could try this:

kubectl get `kubectl api-resources -o name | tr '\n' ',' | sed 's/.$//'`
