What should a beginner Linux/DevOps admin use to learn and how to make something that can be shown as a portfolio?

Question

PHP

Good afternoon. For example, a front-end developer can make websites, make up landing pages, maintain a rich account on github to upload successful and unsuccessful work there. And he can attach all this in the form of links to his resume, and his future employer will see and say: Wow!
What can a linux admin do? Just put in the resume little clear names? Perhaps he can also maintain an account on github and upload his bash scripts there. But that's not all. And for training, you also need to use something (I currently use a bunch of virtual machines and docker). Maybe there is something interesting for admins to do their training projects in a cloud like Cloud9 and upload something somewhere that people can look at? Doesn't this profession force you to remain in the shadows, against the backdrop of beautiful fashionable pieces of front-enders and other specialists? :)

Answer 1

while($row = $result->fetch_assoc()){
    $row['type'] = 'album';
    $r[] = $row;
  }

Answer 2

First of all, you should not be limited to one tower.
You can start a rap on the github and upload scripts in Python, possibly in Ruby (for a change), just as, for example, there are difficult multi-way steps on the same bash, for example, for backup, which is not at all embarrassing to post on github.
Virtual machines and dockers can be hosted on AWS, create an interesting system and show it at an interview if there is a need.
Plus, write articles \ blog \ branches on any resources, the same habr, start a branch, for example, on SpiceWorks (like that they are called, haven’t been to them for a long time) in English, tell something, describe. This will also be a definite plus.
PS It is unlikely that it will be possible to simply indicate the names, you must at least somehow tell about what you did. Most likely if you didn’t do anything, it will be visible immediately.

Answer 3

Why would your employer say wow?
He doesn't care about that.
The main thing for him is that you work properly.
Or do you think that a KAMAZ driver, when getting a job, is obliged to demonstrate races at a speed of 250 km / h and show skills in drifting?
If you know how to work, say so in your resume. And list the main skills.

Answer 4

The easiest option is to write something on the control system. configurations. Here is a portfolio option on Ansible .
