webservers.yml graphic |
The 'webservers.yml' graphic component describes the following playbook:
<...>
notify: restart nginx
handlers:
- name: notify nginx
<...>
As far as I know, these two should correspond. So either 'restart' or 'notify' on both occasions.
Kind regards,
P. Winkelmolen
Note from the Author or Editor:
The graphic Figure 1-1 must be changed: In the graphic, the part "- name: notify nginx" should be replaced by "- name: restart nginx" |

Chapter 2, Creating a Custom Home Page |
Following along with the examples in hm17 “Ansible: Up and Running,” 2nd Edition, Lorin Hochstein, Rene Moser, 2017,
hm17 > Playbooks: A Beginning > A Very Simple Playbook > Creating a Custom Home Page
https://www.safaribooksonline.com/library/view/ansible-up-and/9781491979792/ch02.html#idm140665331790880
the anticipated variable expansion with {{ ansible_managed }} does not occur.
Researching the problem I found a back level Ansible document reference
ansible-docs.readthedocs.io/zh/stable-2.0/rst/intro_configuration.html#ansible-managed
that suggest placing the following line in the ansible.cfg file
ansible_managed = Ansible managed: file modified on Y-m-d H:MS by uid on host
With that change, my results are congruent with the book’s “Figure 2-2. Rendered HTML”.
Note, the current Ansible documentation
docs.ansible.com/ansible/latest/intro_configuration.html#ansible-managed
does not provide the setting for ansible_managed used in the book.
Thank you for your consideration and a very useful book.
warm regards, Chris
Note from the Author or Editor:
Because of changes to the behavior of the ansible_managed variable, we're going to change this example, like so:
- <p>{{ ansible_managed }}</p>
+ <p>Running on {{ inventory_hostname }}</p> |

General Note |
You can find them in the code samples on GitHub... in the "roles" directory. There isn't a "ch08" directory.
Specific link: https://github.com/ansiblebook/ansiblebook/tree/master/roles/playbooks/roles/database/files
Note from the Author or Editor:
The github repository has been updated so that the "ch08" directory appears. |

Example 9-13, in task "copy SSL keys" |
SSL keys are transferred to remote host with permission mode 0644.
It would be more secure to use permissions 0600 or 0640 to limit who can read the private keys. Certainly they should not be readable for everyone.
Line as it is in the book:
mode: 0644
Note from the Author or Editor:
You're right, it would be more secure if instead the permission was set to:
mode: 0600 |

Last paragraph of code |
template:
src: "{{ item.domain }}.conf.j2"
dest: "/etc/nginx/conf.d/{{ item.domain }}.conf
There was a closing quote missing in the dest section, so the playbook cannot run, and the syntax highlight in the playbook already indicated that there was a quote missing.
Note from the Author or Editor:
Missing quote should be appended to dest, as mentioned (fixed in the source). |

Example 9-11 wrapped top of page |
Example 9-12 references variable vhosts_absent whereas example 9-11 defines absent_vhosts
Note from the Author or Editor:
Example 9-11 should be changed to vhosts_absent to be consistent. |
