What could be wrong with this yaml ???
Am I missing something ?

I correct it to

But now I am getting ,

thor@jump_host ~$ kubectl apply --validate=true -f /home/thor/mysql_deployment1.yml
error: error parsing /home/thor/mysql_deployment1.yml: error converting YAML to JSON: yaml: line 74: mapping values are not allowed in this context

Hello, @iVaibhav
Can you please use triple backtick to explore the YAML?
start with triple backtick(```)

YAML HERE

end with triple backtick (```)

It would be easy to read and understand the indentation issues.

Thanks @Tej-Singh-Rana for the trick

I updated the post and now it looks much better

I corrected it. There are so many indentation issues. Please correct your .vimrc file to escape from indentation issues.

Thanks @Tej-Singh-Rana ,

I will compare this with what I tried in lab.

I dont think i will ever be able to come to terms with indentation in python and yaml :roll_eyes: . Wish they were better designed.
