Listing all resources in a namespace

Question

I would like to see all resources in a namespace.

Doing kubectl get all will, despite of the name, not list things like services and ingresses.

Answer 1

Answer of rcorre is correct but for N resources it make N requests to cluster (so for a lot of resources this approach is very slow). Moreover, not found resources (that have not instances) are very slow for getting with kubectl get.

There is a better way to make a request for multiple resources:

kubectl get pods,svc,secrets

instead of

kubectl get pods
kubectl get svc
kubectl get secrets

---

So the answer is:

#!/usr/bin/env bash

# get all names and concatenate them with comma
NAMES="$(kubectl api-resources \
                 --namespaced \
                 --verbs list \
                 -o name \
           | tr '\n' ,)"

# ${NAMES:0:-1} -- because of `tr` command added trailing comma
# --show-kind is optional
kubectl get "${NAMES:0:-1}" --show-kind

or

#!/usr/bin/env bash

# get all names
NAMES=( $(kubectl api-resources \
                  --namespaced \
                  --verbs list \
                  -o name) )

# Now join names into single string delimited with comma
# Note *, not @
IFS=,
NAMES="${NAMES[*]}"
unset IFS

# --show-kind is enabled implicitly
kubectl get "$NAMES"
