Why you need kubesort:

• kubesort helps you sort the results from kubectl get in an easy way.
• You don't have to type kubectl --sort-by=.status.containerStatuses[0].restartcount get po to sort the pod by their STATUS, just type kubesort status that's it.
• kubectl has its own --sort-by=json-path feature for sorting but kubesort will make the sorting easier.

Installation:

Linux Since kubectx/kubens are written in Bash, you should be able to install them to any POSIX environment that has Bash installed.

1. Download the kubesort scripts:
   sudo git clone https://github.com/aathith/kubesort /path/kubesort
2. Make the script executable:
   chmod +x /path/kubesort
3. Create symlinks to kubesort:
   sudo ln -s /path/kubesort /usr/local/bin/kubesort

Usage:

  kubesort sortby namespace_name
 
          sortby: name      # kubectl --sort-by=.metadata.name get po
                  status    # kubectl --sort-by=.status.phase get po
                  restarts  # kubectl --sort-by=.status.containerStatuses[0].restartcount get po
                  age       # kubectl --sort-by=.status.startTime get po
                  ip        # kubectl --sort-by=.status.podIP get po
                  node      # kubectl --sort-by=.spec.nodeName get po
                  help      # List available commands
  namespace_name: all              # kubectl --sort-by=option get po --all-namespaces
                  namespace_name   # kubectl --sort-by=option get po -n namespace_name

v0.1.0 Limitations:

1. As for now you can only sort for kubectl get pod.
2. You need bash in your system.(will add more ways to install in upcomming versions).

v0.1.0 Release notes:

1. Sort by name, status, restarts, age, ip and node for pod.
2. Sort across Namespaces for pod.

v0.2.0 roadmap:

1. Sort for resource Deployments, services, namespaces will be included.
2. Bash auto-completion will be included.
3. more install options.

Tried and Tested:

In k8: v1.15
kubectl: v1.15
ubuntu: 18.04
bash: v4.4
