If you need to copy and paste base64 encoded certificate data into yaml.
How would you do that without getting carriage returns and spaces every line?

I am currently doing it this way: cat user.crt | base64
Then paste in vi
then I have to remove \n and \s
so i do:
:%s/\n*//g
:%s/\s*//g
This is inconvinient because I have to paste in separate file for it to work
Removing \n and \s from terminal ouput with sed for some reason does not work

How to avoid this? Please advice

Jesus Arechiga Jimenez:
don’t copy, pass the value

#3

Jesus Arechiga Jimenez:
or try cat user.crt | base64 -n

#4

Alex Novik:
no such option as base64 -n but I found this in man base64
-w, --wrap=COLS wrap encoded lines after COLS character (default 76).
Use 0 to disable line wrapping
So when I did:
cat /etc/kubernetes/pki/ca.crt | base64 --wrap=0
It works! I appreciate you help @Jesus Arechiga Jimenez
