One day, we just started using Ansible at work. This series is helping tremendously for me to learn and understand quick. Thanks!

[@kalitsiadischaritos4685]

I love your accent & your vocabulary, your channel is the only one that I don't use subtitles.

[@StevenBates-l2f]

Well done! Excellent resource for those learning (like me). Well thought out. Presented in a clear, easy-to-follow manner. Highly recommended. 😃

[@cruepprich]

Excellent tutarials: Clear, concise, well presented, and excellent, simple examples.👌

[@name1355_0ne]

Thank you very much. You did a great job producing the whole Ansible tutorial series! This technology is very handy, so I can't imagine myself without using it from now on )

[@BrotherKaif]

Your tutorials are some of the best on KZbin for Linux. Thank you so much for putting this out there for free.

[@ugetwhenugive]

Your video guides are extremely helpful, you explain things very well and give appropriate examples! Thank you for your work, appreciate it!

[@carlosalonsosouza6439]

What a great video !! I just came to say I love your videos and I plan to say it again cause it's the twelveth and it's been a master class so far. So inpiring in so many ways. God bless you.

[@mathewkargarzadeh3158]

My man this tutorial is getting better and better. my admiration to you for investing your time educating everyone. Thank you !!. Mat.

[@wamiedabdel-rahman5389]

I really appreciate your effort. Simple, basic and to the point. Thanks

[@LearnLinuxTV]

Glad it was helpful!

[@MarkusEicher70]

Thanks Jay. Again a very helpful explanation on how to manage services with Ansible. For this part I will need a lot of practice, especially with the lineinfile and service variable stuff. Very powerful, but also error prone, if not done right, I guess. It's a blast to follow your lessons and I'm looking forward to the rest of the playlist.

[@jgranahan]

great stuff, sir. i love being in the nitty-gritty of plays and ansible commands, but as i was running the playbook, i was thinking "i'm running ansible to 5 vm's"!! cool!

[@realrobin82]

I really appreciate your efforts on making these tutorials. I find them very useful and practical. Keep them up. Also can you create video tutorials for Kubernetes?

[@osswriter]

He does have a Raspberry Pi 4 Kubernetes cluster tutorial.

[@jaecheokkim99]

really helpful video! Thank you so much!

[@AkebonoRadio]

Thank You Jay!!!!

[@jimbrannlund4677]

This video series is awesome! I have one question tho, how come the email change only happens the first time? You're only "grepping" for "ServerAdmin" with the regex, shouldn't that match on every run? Or does Ansible store the state somehow? Ah, I guess it actually compares it to the "line:" value to see if it's already that?

[@carlolucido1187]

Would you have automated the 'sudo firewall-cmd --add-port=80/tcp' as well or just the 'sudo systemctl start httpd'?

[@mihai6564]

good video

[@luke421]

genius!

[@imnottellingyoumyname3050]

I don't understand why restarting the service ENABLED the service on my rhel server?

[@KifKroker]

how come the second time it doesn't fire run, the line starts with ServerAdmin just the same no ?

[@assgex]

Yep, I was asking me the same question...

[@AR-ly5zt]

@@assgex The tasks are guaranteed to be idempotent by Ansible, which means they will alter the file only when necessary

[@antonsurviyanto5896]

Sir, request tutorial about ansible with raspberrypi cluster super computer :) Thank you
