Get all Images running in cluster

List all Container images in all namespaces

if you'd like to get a list of the images running in a given cluster...

kubectl get pods --all-namespaces -o jsonpath="{.items[*].spec.containers[*].image}"

The jsonpath is interpreted as follows:

• .items[*]: for each returned value

• .spec: get the spec

• .containers[*]: for each container

• .image: get the image
