This a Bash Script that will help you forget the kubectl's default, difficult to remember, sorting feature by making it simpler.
kubectl has its own --sort-by=json-path feature for sorting but kubesort will makes the sorting easier.
- It's simple and beginner-friendly.
- Helps you sort the results from
kubectleasily. - You don't have to type the long command
kubectl --sort-by=.status.containerStatuses[0].restartcount get poto sort the pod by theirRESTARTcount, just typekubesortin front of yourkubectl getcmd like thiskubesort kubectl get po restart, that's it.
Linux: Since kubesort is written in Bash, KUBESORT is expected to run on any POSIX environment that has Bash installed.
- Download the kubesort scripts:
git clone https://github.com/aathith/kubesort /usr/local/bin/kubesort - Make the script executable:
chmod +x /usr/local/bin/kubesort
