What it does

kubectl get is the primary read command for K8s. It lists resources with status. Output formats range from human-friendly tables to machine-parseable JSON/YAML. The -w flag watches for changes. Mastering -o and --field-selector transforms kubectl from a query tool into an automation backbone.

Common flags

Flag	Meaning
`-n` `--namespace`	Target namespace
`-A` `--all-namespaces`	All namespaces
`-o` `--output`	Format: json, yaml, wide, jsonpath, custom-columns
`-w` `--watch`	Watch for changes
`--field-selector`	Filter by field values
`-l` `--selector`	Filter by label

Examples

kubectl get pods -A -o wideAll pods across namespaces with node info · explain & risk-check →

kubectl get pods -l app=nginx -wWatch nginx pods for changes · explain & risk-check →

kubectl get pods -o jsonpath='{.items[*].metadata.name}'Extract pod names for scripting · explain & risk-check →

kubectl get nodes -o custom-columns=NODE:.metadata.name,STATUS:.status.conditions[-1].typeCustom columns output · explain & risk-check →

kubectl get events -A --sort-by='.lastTimestamp' | tail -20Recent cluster events · explain & risk-check →

Pro tip

Use `kubectl get pods -o json | jq -r '.items[] | select(.status.phase!="Running") | .metadata.name'` to programmatically find non-running pods — far more reliable than parsing tabular output.
