Figure 1-1

In the tasks section, the name ‘Install config file’ has the following statement: “notify: restart nginx” but in the handlers section, the name is “notify nginx”. The name of the handler should probably be changed to match the notify directive.

Note from the Author or Editor:
This was caught before the 3rd edition went to print.

Chapter 2, Example 2-9. playbooks/webservers-tls.yml

A task to enable the web server configuration, by linking /etc/nginx/sites-enabled/default to /etc/nginx/sites-available/default (or "{{ conf_file }}"), is omitted from playbooks/webservers-tls.yml. If the reader has run webservers.yml and webservers2.yml playbooks from earlier in the chapter then this isn't an issue, but if not, or the Vagrant VM has since been destroyed, the playbook will fail to fully-configure the web server.

This was caught before the 3rd edition went to print.

Chapter 3, Example 3-3. Vagrantfile with three servers (https://learning.oreilly.com/library/view/ansible-up-and/9781098109141/ch03.html#ex3_vagrantfile)

The first line of the Vagrantfile in Example 3-3 is missing underscores ("_") between the words in the variable name. Replace:

VAGRANTFILE API VERSION = "2"

with:

VAGRANTFILE_API_VERSION = "2"

This is correct in the ansiblebook repository at https://github.com/ansiblebook/ansiblebook/blob/3rd-edition/ch03/Vagrantfile

Note from the Author or Editor:
This was caught before the 3rd edition went to print.

9. Customizing Hosts, Runs, And Handlers Running on a Batch of Hosts at a Time the description under figure Example 9-8

In the preceding play, with 30 CDN hosts, Ansible would run against one host on the first batch run, and on each subsequent batch run it would run against at most 30% of the hosts (for instance, 1, 10, 10, and 9).

=> "1, 9, 9, 9, and 2" is correct, not "1, 10, 10, and 9".

Note from the Author or Editor:
This was fixed before going to print with the 3rd edition.
