Get pod IPs by label across all namespaces with kubectl JSONPath

Custom-columns is fine, but JSONPath gives you raw output you can pipe straight into other tooling.

#kubernetes
#kubectl
#jsonpath

Source.

bash

kubectl get pods -A -o jsonpath='{range .items[*]}{.metadata.namespace}{"	"}{.metadata.name}{"	"}{.status.podIP}{"
"}{end}' | grep -v NAMESPACE

# Filter to one deployment's pods + their nodeName:
kubectl get pods -l app=my-app -o jsonpath='{range .items[*]}{.metadata.name}{" -> "}{.spec.nodeName}{"
"}{end}'

Zero-friction retrieval.

Pipe it straight into your shell

$ curl -fsSL https://blog.harshhaareddy.com/raw/xx3ant2tzq5lut70fb0787pv | bash

Pipes the raw source straight into your shell. Review the raw output first if you are cautious.
