kubectl output

kubectl-output is a plugin for kubectl that allows users to set custom output format for specific resources/namespaces. Custom output format is based on custom-columns.

Example of how user can set custom output format for Pod resources in test namespace:

kubectl output set pods -n test -o custom-columns=NAME:.metadata.name,STATUS:.status.phase,NAMESPACE:.metadata.namespace

The config is stored in ~/.kube-output/resource_tmpl_map.yaml file. Which is later used to set custom output format for related requests made with kubectl output get command. For example:

kubectl output get pods -n test

Examples:

alias ko="kubectl output"

# create default template
ko set pod --name=test -c=NAME:.metadata.name

# create template for kube-system namespace from file
cat pod.tmpl
# NAME          RSRC
# metadata.name metadata.resourceVersion

ko set pod --name=test-file --namespace=kube-system -c=./pod.tmpl

# list all templates for pod
ko template pod -a
# test
# test-file

# get pods with default template
ko get pods -A
# NAME
# pod1

# override default template
ko get pods -A -o test-file
# NAME                 RSRC
# pod1                 123
