My Most Used Commands for Kubernetes

And how you can find yours

Thought it might be a silly exercise to see which commands I’ve run the most, maybe they’ll be helpful for your Kubernetes journey.

Let’s take a look!

How Do You Query for Them?

The history command will spit out your old commands but it also includes nubers to refer back to the command. I was able to instead grep my ~/.bash_history file for certain commands, and then cut the output so that I could see what commands I issued the most by the relevant pieces.

The Results

Just the first field, i.e. which command do I use most, kubectl or its alias, k (which I highly recommend to save yourself some typing)

cat ~/.bash_history | grep -v '#' | grep -E '(^k |^kubectl)' \
    | cut -d" " -f1 | sort | uniq -c | sort
 177 kubectl
3052 k

Clearly k wins.

Now for the second field

cat ~/.bash_history | grep -v '#' | grep -E '(^k |^kubectl)' \
    | cut -d" " -f1-2 | sort | uniq -c | sort
  32 k run
  36 k top
  66 k port-forward
  74 k config
  80 kubectl get <--- same as `k get`
 106 k exec
 124 k delete
 289 k describe
 339 k logs
1902 k get
