V-242414 For any of the pods that are using ports below 1024,
|
||
|
reconfigure the pod to use a service to map a host non-privileged
|
||
|
port to the pod port or reconfigure the image to use non-privileged ports.
|
||
|
|
||
|
V-242442 To view all pods and the images used to create the pods, from the Master node, run the following command:
|
||
|
kubectl get pods --all-namespaces -o jsonpath="{..image}" | \
|
||
|
tr -s '[[:space:]]' '\n' | \
|
||
|
sort | \
|
