Get the image and SHA image ID of images in pod on Kubernetes deployment

问题

How can I get the image ID (the docker sha256 hash) of a image / container within a Kubernetes deployment?

回答1:

Something like this will do the trick (you must have jq installed):

$ kubectl get pod --namespace=xx yyyy -o json | jq '.status.containerStatuses[] | { "image": .image, "imageID": .imageID }'
{
  "image": "nginx:latest",
  "imageID": "docker://sha256:b8efb18f159bd948486f18bd8940b56fd2298b438229f5bd2bcf4cedcf037448"
}
{
  "image": "eu.gcr.io/zzzzzzz/php-fpm-5:latest",
  "imageID": "docker://sha256:6ba3fe274b6110d7310f164eaaaaaaaaaa707a69df7324a1a0817fe3b475566a"
}
