Tail log for kubernetes pod by geting list of pods and filter by substring

kubectl-log-tail.sh

#!/bin/bash
namespace=mynamespace
pods=$(kubectl get po -n $namespace -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{end}')

for i in $(echo $pods | sed "s/\t/ /g")
do
  case $i in *"$1"*)
    kubectl logs -n $namespace $i --follow;;
  esac
done

Got bored of listing kubernetes pods and then geting the generated name to get a tail log.
call script by:
sh kubectl-log-tail.sh some-service
