Ansible Roles

Collect Ansible roles for automatic deployment.

Requirements

---

1. Ansible (version 2.5.6) should be installed first. In addition, we should also prepare an Ansible inventory file to run this playbook.

   Inventory File Example:

   [servers]
   servers ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 ansible_ssh_user=vagrant ansible_ssh_private_key_file=.vagrant/machines/default/virtualbox/private_key
   

2. All roles are developed base on CentOS 6.7, ensure remote machines have the same OS.

Usage

---

1. Modify your Ansible playbook as needed.

   Playbook Example:

     ---
     - hosts: servers
       roles:
         - { role: dropwizard-api, become: yes }
       	- { role: hubot, become: yes }

2. Copy vault-example.yml to vault.yml, modify values as necessary, and encrypt vault.yml:

$ ansible-vault encrypt vault.yml

and enter a password for the encrypted file when prompted.

3. Run the Ansible playbook:

$ ansible-playbook -i inventory example-main.yml

and add --vault-id /path/to/vault/password-file to specify vault password file or --vault-id @prompt to be prompted for vault password
