ansible-deployer for Debian/Ubuntu

Ansible role for adding a deployment user named deployer to the system.

Overwrite Default Variables

The vars/main.yml file should contain your list of packages you want to install in order to override defaults found in defaults/main.yml.

---
deployer_username: deployer
deployer_password: some_password
deployer_public_key: "{{ lookup('file', '/home/user/.ssh/id_rsa.pub' ) }}"

groups_to_join:
  - sudo
  - ssh
  - www-data

Additionally, you can overwrite the variables as part of your playbook.

---
...
  vars:
    deployer_username: deployer
    deployer_password: $1$BYnbBLbt$uPcFu8SPIZdxqPh61
    deployer_public_key: "{{ lookup('file', '/home/user/.ssh/id_rsa.pub' ) }}"
    groups_to_join:
      - sudo
      - ssh
      - www-data
...

The lookup

This method, will get a value of a given file from anywhere on the system. Just replace the /path/to/public/key with an actual path to a ssh key file.

For example:

"{{ lookup('file', '/home/username/.ssh/id_rsa.key' ) }}"

Generating User Passwords

Originally copied from Servers For Hackers - Ansible User Example

Linux passwords are encrypted using SHA-512. Ansible's documentation on generated encrypted passwords point out the command mkpasswd --method=SHA-512. This asks for a password and returns the encrypted version of it after encrypting it used the SHA-512 method.

On Ubuntu 14.04, the mkpasswd command comes with package whois:

sudo apt-get install -y whois

After installing whois, you can use the mkpasswd command.

mkpasswd --method=SHA-512
Password: <enter your password here>

This generated hash should be what you set as your admin_password and deploy_password values.

Alternatively, you can use openssl passwd -salt <salt> -1 <plaintext>

Deployment SSH Key

As part of the playbook, a ssh key will be auto generated for the user located at ~/.ssh/id_rsa.

Don't forget to add ~/.ssh/id_rsa.pub to your Github.com/Bitbucket/Other repository.

Debugging

If you run into errors, uncomment the - debug: msg="{{ ... }}" statements.
