Very informative Christian! So many dont provide the details on real world Ansible setup for many servers with different passwords. Thank You from Texas US!

Thanks for this great tutorial! It helped me a lot getting started with ansible. Keep up the extremely good work

Thank you, Christian, for making this video. It helped me to get started with Ansible. Trying to get started by just visiting the Ansible documentation is daunting.

Wow man that's a no crap goldmine! Thank you, enjoying the video quite a lot, and I have what I was searching for for the last 3 hours!! :p

good starting point for ansible, short and informative; thumbs up!

[MrHanSoL]

Excellent!! Just what I was looking for! You helped me tremendously with clarifying on using the ansible.cfg and inventory files correctly. Thank you for sharing 🙏 I forgot I had seen this and had to revert back 😁

10:17 you don't need the three hyphens.
It comes from the YAML spec. The hyphens are a separator, before are directives (like yaml version, yaml tags, ...) and after is the actual yaml content. If you have no yaml directives, then you *may* drop the 3 hyphens. Yaml directives are not really relevant for ansible, so feel free to drop the hyphens. Similarly, the yaml spec specifies 3 dots to end yaml content. That's when one document contains multiple yaml parts, or when the yaml is not a file but a stream and you want to signal your yaml processor to stop instead of waiting until the stream is closed. Again, not relevant for ansible, so drop the 3 dots. I think almost everyone is doing that already without knowing why.
I suggest to configure your yamlling to NOT check for --- or ...

I find it kinda funny to see old fashion ordner maps behind Christian.

Thanks for the great intro to Ansible. I have no experience in this area but interested to learn as much as possible. Do you use Nagios? I guess it is commonly used for monitoring.

[morikuldip]

please create a video playbook for installing ansible for install adminer in targeted server.

Entirely curious -- I really like your terminal layout. I see you're using powerline theme...what shell are you using? Zsh? and what terminal emulator? I really like the paste prompt.

My OCD is kicking in and I noticed on the right side of your prompt, you have some artifact bleedover in the symbols. I believe you need to use a different patched Powerline font to get rid of that. Of course, just because it bothers me doesn't mean it bothers you, or anyone else!

Thanks for the video! The best one of starting with Ansible I found :)

But I have one think to ask: Wouldn't it be safer to only add the user to the sudoers file and add the nopasswd instead of allow it for all users?

[madhavreddy]

Hi, I actually setup the Ansible master and server configuration in two docker containers. When I am executing the following command it is asking for sudo password:
```ansible-playbook <playbook-name>```
- My question is when it is asking for "SUDO" password, what I need to enter there
a. Root password of worker container ?
b. Password of the user that we defined in hosts file (ex: Madhav user) of worker container ?

Can you show how to automate Oracle database patch on Linux server using Ansible....please
