I highly recommend Jeff’s book about Ansible: Ansible for DevOps, Server and configuration management for humans. Jeff is very casual and accessible in his videos, but trust me, he’s a real pro when it comes down to server automation. Collecting technical books is my hobby. Recently I was preparing a new category of books in my collection - Linux hardening and server automation. After a thorough research I decided to place Jeff’s book (I finished reading it a couple days ago) as a go to manual for Ansible in that list. Yes, it’s that good. It’s my first comment on this channel and I don’t comment much on YT in general, but - kudos to you, Geerling Guy! Great, great stuff. Keep up the good work.

I know exactly what you mean about using a tool you know a lot about for as many uses as possible. After a decade spent learning everything to know about my job when I was in the Army, I started using my M1A1 Heavy tank for hard drive destruction. Turns out that a 62-ton main battle tank is perfect for destroying 3.5" platter drives on concrete. Crushes 'em flat with very little damage to the tank's track pads. I also learned how to cook using the tank's jet turbine engine. Sure, the food tasted a little like diesel fuel but the overall effort was worth it to avoid having to eat another MRE. It also worked great for chasing bad guys through houses - just put the main gun tube over the back deck and charge after them. Now I'm a network engineer and life is boring as hell.

Jeff this was one of the--if not **THE** best presentation/video you have done. I knew we had a lot of interests in common, and this confirms it. Ansible is one of the best configuration and configuration management tools, and when combined with other leading-edge open-source (from Hashicorp, Docker, etc.), it allows one to manage many. My home "lab" depends on it to manage all of the servers, workstations, network routers and switches, and of course, IOT devices. You've earned a Sugar Fire lunch for this one for sure!

[@russoz]

hi Jeff, you might have seen me on the Ansible Community chat. Despite being active in the c.g collection, I actually started using Ansible little more than one year ago, and what drove me to it was almost the same motivation you had for your Mac setup. I am a Linux guy at heart, so last year when the laptop crashed for whatever reason and I had to reinstall it, I thought the same thing: "I should really automate that setup". That lead me to the `xfconf` module, which was in dire need of some TLC, which eventually made me the maintainer of that module. From that point on, I've start submitting many contributions and eventually became a co-maintainer of the collection. My personal configuration playbook has increased its size many times over since last year. Last run when through more then 500 tasks (overall, including roles and loops). Thanks for all the awesome work you have been doing with Ansible!

I built a fully automated VM deployment system using ansible. it's built atop a mysql dynamic inventory, it ingests yaml files for individual VM configs, creates a vm in the correct xcp-ng pool according to the yaml file, and adds it to the dynamic inventory. It then dynamically builds debian net install ISOs with templated vars that pull down the preseed files, and is set up so that it will automatically run postinstall playbooks after the OS install completes. it's kinda a frankenstein's monster of a platform, with some really ugly accounting for edge-cases, but it does work, and saves a ton of time over the many completely manual installations I had to do before I built it.

One of the things I ran into was the speed of ansible was less than ideal, because it did a python ssh connection for each and every step. There were certain things that were just much faster and more streamlined by the builtin module "script" where there were a LOT of steps. For example, we have an application install script that seems like it is built for ansible to run: creation, permission, and installation of files, directories, and packages. But the larger the build, the slower it was on ansible than it was to upload an install script and run that. Like ansible took 11 minutes versus the 5 from a bash script per server. The problem with "script" is the output of the job (its debug module) is very limited, littered with json garbage, and can't handle progress bars. So while I *could* use ansible, I realized it wasn't efficient enough where I *should* use it.

[@JeffGeerling]

I know some older versions didn't use a persistent SSH connection, but newer versions should by default, I think-meaning your SSH connection is shared among tasks in one playbook making it a bit faster. But even so, there are a lot of little performance issues that can add up, and I wish Red Hat took the performance more seriously :(

Any chances to see an updated version of Ansible Collections and testing roles with Molecule inside a collection with the dependencies from the same, sibling and external collections? I found it quite "interesting" to figure out, how dependencies should be listed in order for Molecule to work. Other thing i do quite often is tie Ansible and Terraform together. Like... i could run Terraform to provision servers and once servers is up Terraform runs Ansible to do the final configuration. On top of that i had integrated that into CI pipeline. If i need new machine, i just push the changes to the remote git, and after couple of minutes i have a new machine ready for a workload. Like this approach pretty much. The only downside of this is that initial infrastructure provisioning should be triggered manually. :) But i think i'm close to deploying Skynet soon. :)

[@JeffGeerling]

I'm actually working on some Terraform + Ansible work for my 2nd Ansible book, 'Ansible for Kubernetes'. It's been a long time coming though :O

[@Oswee]

@@JeffGeerling Oh, that's nice! Then i could potentially mention some particular things. The Secrets. Any kind of them! There is differences do you call Ansible with remote_exec from Terraform or the other way around. If you execute Terraform from Ansible itself, then you can just utilize Ansible's Vault and safely store secrets encrypted in repo itself. If you are executing Ansible from Terraform, then... you need to think how to manage secrets. What i did, was deploying Hashicorps Vault and injected secrets (keys, passwords, TLS, etc) at CI stage (Jenkins has extensions for that). Anyway... secret management i found to be quite "interesting". Other thing i could mention is environment management. You most likely want to provision staging, production and other environments. How do you structure you project for maximal module reusability? What i did, i made some "external" TF modules, which at local development stage i sourced as local files. But when they are done, i can just switch to sourcing directly from remote git (no need for terraform cloud). Also some was just local modules. In Ansible side i also did several environment directories, each containing it's own ssh config and group/host variables. Terraform global variables. Still not quite happy with my solution with feeding in some custom *.tfvars file. For example set of dns domains which are the same for different environments. Or some paths, links to storage, etc. I am even not sure if i do things right if i am reaching for some kind of global vars. Terraform random placeholders. For example you have module which provisions some resource. If user of the module does not provide explicit name of the resource, then you could use things like "random_pet" as fall-back/default/placeholder which you can do only in locals. But again, there are some caveats and bad/good practice rules. And lastly, i found really great way to test the whole setup by utilizing "dmacvicar/libvirt" provider, which allows to to spin up virtual environment without paying for Bezos space flights. :) Overall really interesting topic!
