Some useful playbooks for ansible.

Hosts can be defined inside /etc/ansible/hosts, e.g.,

[local]
localhost

Otherwise, you can use the -i hosts option to take the local hosts file.

Run ansible-playbook with given yaml file name, by default, will apply the stack on all host.

e.g.,

$ ansible-playbook web-server.yml

$ ansible-playbook site.yml --limit webserver

This will apply the role in yml file to all hosts. site.yml will apply the whole stack.

If you wanna run at localhost without ssh, then just add -c local, e.g.,

$ ansible-playbook -c local  common.yml

You can also modify the playbook to change the default role.

For instance.

- hosts: servers
  roles:
     - { role: web-server }

Some common tasks like

• Update system cache
• Install/Config ntp
• Install tmux.

Install docker to the system.

Will apply on the webserver type host.

• make sure Nginx is installed
• make sure Nginx is running

The project is highly inspired by the ansible-examples.
