دانلود کتاب Ansible -راهنمای عملی برای مدیران و تیم‌های Devops

It must have been 2014 when I first became aware of Ansible. At that time, I had no experience with configuration management systems; where necessary, I used shell scripts or Perl when more complex logic was required. So, I kept it in the back of my mind for a while, as old habits die hard. Eventually, the time came for a new installation of a private server, and I took that as an opportunity to learn a bit more about this tool—via learning by doing, which is still the best method for me. And lo and behold: after developing about 240 tasks (individual steps), some of which were very tedious and distributed across several YAML files, I had the complete description in hand with which I could fully automate my server from the barebones delivery state to production-ready status. Fascinating! (I also enjoyed resetting the server during testing and watching the playbook run while sipping my coffee.) So, alongside Perl (and Linux in general), I found a new favorite tool. When it was announced at the end of 2015 that Red Hat had acquired Ansible Inc., I was also quite sure that the topic would not be a flash in the pan. Since I’d always had a side job as an IT trainer, I began to develop and offer a training course on the topic of Ansible. (As trainers say, “If you want to learn more about a topic, then teach a course on it.”). That also was very successful and educational. At the same time, I successfully utilized Ansible in several projects and thus gained additional experience with it. When you discover something valuable, you naturally want to share it—and I wanted to publish something on the topic of Ansible, which led me to contact Rheinwerk Verlag, a publisher in Germany. The result was a chapter in the fifth edition of the popular Linux-Server handbook, which was published at the end of 2018. I had to fit the topic into only 80 pages due to space constraints, but in hindsight, that was enough for a start. (Writing books is more work than you think, and this one wasn’t even my own.) By the end of 2019, we all thought it would be a good idea to dedicate a book to the topic of Ansible—and in September 2020, the first edition actually appeared and I was ready for a vacation. Of course, time hasn’t stood still since then—especially not in IT. That’s why you are now holding an updated and expanded English edition in your hands. What’s new since it first published in German? I have “dusted off” many areas, reassessed things, and incorporated new experiences from my practice. A completely new topic I added is the Proxmox virtualization platform and its management via Ansible. Additionally, I have become very fond of the Python programming language over the past few years, so the example scripts are now consistently implemented in Python. (Goodbye Perl! I loved our time together!) What remains is definitely fun with Ansible—an extremely successful tool. I know of no other software that does so many useful things while annoying me so rarely.
