Ansible Galaxy
What is Ansible Galaxy?
Ansible Galaxy is a galaxy website where users can share roles and to a command-line tool for installing, creating, and managing roles.
Ansible Galaxy gives greater visibility to one of Ansible's most exciting features, such as application installation or reusable roles for server configuration. Lots of people share roles in the Ansible Galaxy.
To work with Ansible Galaxy, you need to use the ansible-galaxy command and its templates. Roles must be downloaded before they used in the playbooks. They are placed into the default directory that is /etc/ansible/roles, also depends on your version, they might placed in your current user home directory.
Currently we don't have any roles in default place:
[user1@controller demo-galaxy]$ ls /etc/ansible/roles/Search on Galaxy
ansible-galaxy search searches for roles on the Ansible Galaxy server. Lets search for apache for example:
[user1@controller demo-galaxy]$ ansible-galaxy search apache
Found 3237 roles matching your search. Showing first 1000.

- geerlingguy.mysql (3.3.2) was installed successfullyLets take look at what it has downloaded:
[user1@controller demo-galaxy]$
[user1@controller demo-galaxy]$ ls /home/user1/.ansible/roles/
geerlingguy.apache geerlingguy.mysql
[user1@controller demo-galaxy]$
[user1@controller demo-galaxy]$ cd /home/user1/.ansible/roles/
[user1@controller roles]$
[user1@controller roles]$ cd geerlingguy.apache/
[user1@controller geerlingguy.apache]$ ls
defaults handlers LICENSE meta molecule README.md tasks templates vars
[user1@controller demo-galaxy]$
[user1@controller geerlingguy.apache]$ cd ~/demo-galaxy/
[user1@controller demo-galaxy]$For using downloaded role, we have to create a simple playbook:
---
#Sample playbook for galaxy and roles galaxy-playbook.yaml
- hosts: all
