Print all resources in a Kubernetes namespace
TL;DR
A little helper to print all Kubernetes resources in a namespace.
Here it is:

#!/bin/sh
kga() {
local ns="${1:-"default"}"
local resource
for resource in $(
kubectl api-resources --verbs=list --namespaced -o name \
| grep -v "events.events.k8s.io" \
| grep -v "events" \
| sort -u
); do
outcome="$(kubectl -n "$ns" get --ignore-not-found "$resource")"
[ -n "$outcome" ] || continue
printf '%s/%s\n%s\n-------\n' "$ns" "$resource" "$outcome"
done
}
grep -- kubectl-get-all-in-a-namespace "$0" >/dev/null 2>&1 && kga "$@"It is actually a refinement of this answer on StackOverflow, with the following additions:
- defaults to namespace
default; - does not print anything if there are no resources of a given kind, producing a more compact output.
The downside of the second bullet is that it is most probably not exactly the best thing for very crowded namespaces.
The script doubles down as a library and a script that can be executed, in pure POSIX shell modulino spirit.
