Just a lil tip for making all the folders and files for the structure in his example. Be inside the roles folder and type: mkdir -p {base,db_servers,web_servers,workstations,file_servers}/tasks This will make each folder in curly brackets contains a tasks folder in each.

[@MarkusEicher70]

Thanks for the handy tip, Ryan. 🤛

[@magnuslator4719]

Thanks for the tip. From the project root folder, the following command can be run to create the roles folder and sub-folders: mkdir -p roles/{base,db_servers,web_servers,workstations,file_servers}/tasks

[@bfrd9k]

for role in base db web workstation file ; do ansible-galaxy role init --offline "${role}" ; done

[@rafal9ck817]

can also do mkdir roles/{base,db_servers,file_servers,web_servers,workstations} ; cd roles ; for i in * ; do mkdir "$i/tasks" ; done ; cd - from repo root

[@jacksoncremean1664]

I always love how you break things down give people the basic tools they need to get started to then play around and familiarize themselves with the tool top quality as always!

[@fabrice9848]

You're an excellent teacher, and a perfect example of how the FOSS philosophy makes the world a better place.

[@MCSMIK]

This is probably the first new thing that I did in ansible after watching this video, which actually worked the first time. Really appreciate your effort in making this series!

[@bluekornchips]

Fantastic video. I gave a take home assignment for Ansible and your video series is a life saver. Easy to understand, well spoken, and explains concepts immediately when questions may arise. Thank you!

[@ice_tee]

I was wandering here and there trying to learn proper execution of ansible and my search ended here. Slow, practical explanation and each and every step explained. Thank you so much for this !!!

[@MarkusEicher70]

Cool stuff, Jay! Thanks for another great part in this series. That makes a much better structure and allows to define custom roles I need in my setup. Now I can't wait to see the further improvements of using host variables. This series was a blast so far! 💪

[@LearnLinuxTV]

Glad you enjoyed it!

[@dono42]

Why not simply use "ansible-galaxy init " to setup the folder structure for roles?

[@jaecheokkim99]

Jay. thank you for every videos :) it's definitely best ansible tutorial video.

[@jhred3315]

Definitely clear my confusion about role! Thank you so much!

[@hideyukikanazawa2761]

Very nice and concise explanation for a not so intuitive topic.

[@vialomur__vialomur5682]

The best series! This is great!

[@jgranahan]

Really great, Jay. This brings a lot together, letting me hone my TMUX and VIM skills as well!! Love it!

[@name1355_0ne]

Thank you very much for the explanation!

[@mathewkargarzadeh3158]

Thank you Jay !!!. gratitude to you.

[@cruepprich]

Excellent, as all the other videos in this series. Thanks!

[@ThePandaGuitar]

Clearly explained and easy to follow. Thank you very much!

[@shivakarki6887]

You have been very helpful, thank you sir. I wish to learn Jenkins from you too, someday.

[@stalinengoma7680]

Excellente vidéo. I’m speechless

[@debadutta75]

You are excellent Jay

[@muksyed]

Hi Jay. Great videos. BTW, IMHO the “tree” command helps to see the entire role structure.

[@mysydney71]

best Ansible roles explanation/example I have ever seen

[@randzioful]

/> mkdir -p roles/{first_role,second_role,third_role}/tasks

[@johannesmauser5465]

very good video :) Worked first time

[@ayencoscolfield3312]

Thank so much cant really thank you enough, you rock man

[@MrDominique1992]

So nobody knows the command ansible-galaxy? It creates all the role folder/subfolders/files in one command

[@majorgear1021]

Well done! Btw, I notice you have a System76 linux laptop. Have you done any videos about it? From purchase to setting it up, to features of both the laptop and popos? I’m currently a Mac user, As more and more apps go subscription, I’m thinking about switching to Linux as my daily driver instead of just a server OS.

[@JamesGreen-gv4yn]

I find it interesting that you start by making a copy so that you have the original when that is precisely why you are using 'git'. You can go back to the original or see your change at any time by using the git commands.

[@arunkumarkt8730]

superb explanation. Thanks a lot sir.

[@hamidja1537]

Thanks for sharing

[@samsonwong2397]

excellent explanation

[@miladvaziri3]

so useful, thanks for teaching me

[@SoulJah876]

This all worked with me leaving my html file inside the original files folder.

[@tsushima33]

Great, easy to follow

[@petermuia9519]

Hi Jay, I have religiously been following all the steps in all your labs for this Ansible series & have one query. After all the additions: copying & pasting into the relevant main.yml. Does one then remove the plays in the site.yml file that correspond to these copy & pastes. I took the liberty of removing these plays in my site.yml file & when I ran the new site.yml file, I got results not similar to your's. Example apache2 was installed on the other Ubuntu servers. To reiterate, until this Roles lab, all my previous labs corresponding to yours generate all results like your's

[@gurlalsidhu2503]

not just ansible, i got to learn linux too :)

[@AkebonoRadio]

Thanks Jay!!!

[@mihai6564]

thanks for the video

[@nixoncoronado5558]

Hello Jay, I want to create different roles to get status, start and stop supervisorctl. I would like to ask if possible to create one yml file to execute all those roles?

[@NH-ly7zc]

Thank you

[@Peet0103]

I understand now

[@karobarc]

i dont see the code for adding roles here

[@JackReacher1]

Liked it

[@tjbredow]

You must be very patient to do this all in nano.

[@pralaybagde4804]

Can u plz tell me , how to execute .sh file in ansible roles .

[@rohitreddy578]

- name: script execution command: sh /home/script.sh

[@miyalys]

explicitly calling sh should not be necessary if the hashbang line is set?

[@dylanevans2732]

Thanks. You spelled vim wrong.

[@fabrice9848]

Seeing you using nano when you'd rather use vim is truly painful!

[@alexanderpoplawski577]

Great series! I can't see the role where the user simone is created, like in the site_before_roles.yml. Did I miss that? EDIT: Found it, it is in the bootstrap.yml.

[@hamidja1537]
