Log user's writes in the TTY

[llaoj]

Sometimes, we want see the operations log in the terminal when enabled -w.

Write log

If you set --write-log option, user's writes in the TTY can be Logged. for example:

if you run gotty like this:

./gotty -w --write-log --permit-arguments ./test.sh

this is test.sh:

#!/bin/bash

echo "Welcome: $4"
kubectl -n $1 exec -it $2 -c $3 -- sh

visit http://127.0.0.1:8080/?arg=without-istio&arg=sleep-7b6d569576-57sjq&arg=sleep&arg=21001713 and input your commands in shell, and you will see user's writes in the log (operation logs):

...
2022/11/13 10:48:12 [write-log] {"arg":["without-istio","sleep-7b6d569576-57sjq","sleep","21001713"]} lsCR
2022/11/13 10:48:14 [write-log] {"arg":["without-istio","sleep-7b6d569576-57sjq","sleep","21001713"]} pwdCR
...

Using the [write-log] flag, you can collect and store these logs persistently. All args are in the log, including the userID.
