K9s: Custom commands with pipes example?

[rahilb]

Hi folks,

just wanted to say this is a great tool and saves me tonnes of time!

I was wondering if it's possible/what the syntax is for a custom plugin with pipes? E.g. my pods log in json so I would like to pipe the output through JQ, I tried:

plugin:
  jlogs:
    shortCut: Ctrl-J
    description: "Json Pod logs"
    scopes:
    - po
    command: /bin/sh
    background: false
    args:
    - -c 
    - "kubectl logs -f $NAME -n $NAMESPACE --context $CONTEXT | jq -r '.message'"

But no joy. Has anyone done something similar?

@rahilb Sorry it's taking me a while to get back to you on this ;(

Please let me know if this works for you! Tx!!

I think you should be able to leverage kubectl plugins for that and get this working with K9s as a plugin as follows:

# Add kubectl-jq somewhere in your path and change to your shell of choice!
#!/bin/bash
/usr/local/bin/kubectl logs -f $1 -n $2 --context $3 | jq -r '.message'

Add the plugin as follows:

# $HOME/.k9s/plugin.yml
plugin:
  jlogs:
    shortCut: Ctrl-J
    description: "Json Pod logs"
    scopes:
    - po
    command: kubectl
    background: false
    args:
    - jq
    - $NAME
    - $NAMESPACE
    - $CONTEXT

Thanks @derailed it worked perfectly, there was a couple of typos in the code you pasted, here's the working solution:

/usr/local/bin/kubectl-jq

#!/bin/bash
/usr/local/bin/kubectl logs -f $1 -n $2 --context $3 | jq -r '.message'

$HOME/.k9s/plugin.yml

plugin:
  jlogs:
    shortCut: Ctrl-J
    description: "Json Pod logs"
    scopes:
    - po
    command: kubectl-jq
    background: false
    args:
    - $NAME
    - $NAMESPACE
    - $CONTEXT

Thanks again for making such a great tool!

@rahilb Cool!! Thank you for reporting back! Not a typo in the example I am leveraging kubectl plugins.
