In the previous post, I was trying to get my ssh to work with ansible.
So today, I decided to continue with automation with ansible. I explored the ansible-playbook package and created an inventory, roles and a playbook ultimately.
In the book, I was to automate two tasks:
- Create users
- Install some packages.
I had difficulties setting up the ssh again but well, I was able to fix it. The creating users tasks required the use of
sudo. I mean,
sudo is actually a bastard - shey it can't revert my mistakes ni.
Creating users & Doom...
My default user on my machine is Youngestdev, in the book, we're to create a user to have its own enviroment, ssh keys etc... I was like well, let's get to it. I was actually tired ( sleep deprived due to one or two things ) and I wanted to just finish the chapter so I can begin a new one tomorrow.
Mumu me went to use my default user name as the user to be created giving it new UID, GID, and file permissions.. I didn't realise until I woke up - I had granted a read-only permission to my disk".
I had shutdown already and when I restarted the laptop, I couldn't open applications except the terminal. I had to reinstall my OS, luckily, I don't have any important data ( I think.. ) as it's a fresh installation.
Now, I have a new OS installed and didn't download that book again for these reasons:
- Outdated information
- Lack of cautionary messages
- Not beginner friendly
I'll just tread carefully with these books and use more of documentations tbh, I should've known better than to run
sudo carelessly but, mistakes happens and that's a mistake I def won't make again.. hopefully.
I'll set up everything again - ssh, docker, ansible. I'll be taking my time more carefully to study books before executing commands and run to the documentation as those are the materials that have aided in the last few days.
I got a new book, and I'll take my time to review it before I decide to either keep it or trash it.
Thanks for reading, Etin!
