[mcheck]

On p35 of 2nd Ed.:
ansible app -b -m package -a "name=git state=present"

Servers created as CentOS8s.

In the machine:

[vagrant@orc-app1 ~]$ sudo yum update -y
CentOS Linux 8 - AppStream                                          152  B/s |  38  B     00:00
Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

Stackexchange suggests this is a resolv.conf issue, but even replacing resolv.conf with

nameserver 8.8.8.8
nameserver 8.8.4.4

Same error results.

The error message you're receiving:

Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

is from yum, not Ansible - this is a problem with your app servers installation or configuration - you will need to ask on a CentOS support forum.

This seems to be the result of CentOS 8's EOL. At some point I may switch the examples to Rocky Linux 8 instead. (Yet another effect of the CentOS 8 rug-pull, grr...).

This seems to have started happening within the past week.

See geerlingguy/packer-boxes#80 — I'm planning on adding a rockylinux8 build soon.

Hey there, I'm really enjoying your book and videos :)

Wanted to add, that this issue is present in other places. I just faced it on page 20 and in the config file here on GitHub you have geerlingguy/centos8, but after in the book and in the videos on YouTube you talk about CentOS 7.

In the screenshot, line 8 in the code and the last line of text at the bottom.

I have these references fixed in the manuscript. I hope to have an update out tonight!
