Here is a script I use to find out which namespaces have problem pods and what the problems might be. I call the script notrunning

kubectl get po -A --no-headers |
awk '
  BEGIN {
    SUBSEP=" "
    format = "%-20s %20s  %5s\n"
    printf format, "NAMESPACE", "STATUS", "COUNT"
  }
  !/Running/ {a[$1,$4]++}
  END {
    for (i in a) {split(i,t); printf format, t[1],t[2],a[i]}
  }
' | sort

I get results similar to this:

$ notrunning 

NAMESPACE                                                  STATUS  COUNT
namespace-01                                     InvalidImageName      2
namespace-02                                     InvalidImageName      1
namespace-02                                Init:ImagePullBackOff      1
namespace-03                                     CrashLoopBackOff      2
namespace-03                                     InvalidImageName      9
namespace-04                                    Init:ErrImagePull      1

You can go about it the kubectl way like Samuel suggested, or a more bash-oriented way.

Here are a few I use and when I use them

kubectl get po -A | grep Pending Looking for pods that have yet to schedule

kubectl get po -A | grep -v Running Looking for pods in a state other than Running

kubectl get po -A -o wide | grep <IP> Looking at all pods state for a given node

grep is a pretty powerful CLI tool with regex support that can help filter the output of kubectl commands.

Here's the man page for grep
