Added sudo uniformly everywhere it required as it presence doesn't affect anything , but it help new user's of linux , docker or kubernetes who are not much familiar with internals and also for who doesn't read the documentation line by line and use the guides for command reference and just copy paste for their use.
Also , changed the way of writing or creating files , now using "tee" because previous way gives permission issue for non sudo users.
