Ansible Ubuntu Box

Simple Ansible plays to configure a Ubuntu Server (14.04).

I find myself having to do the same setup each time I start a new server. Simple things like adding my public key to the authorized key file and configuring UFW to allow some ports.

Here are somethings that are automated now:

Creates and sets up a new user (newuser.yml)
- Creates new user
- Configures passwordless ssh access
- Adds user to sudoers
- Disable root ssh access
- Disable ssh access via passwords
Installs various things (main.yml)
- Apt (tasks/apt.yml)
  - Updates and upgrades apt-cache and installed packages
  - Installs Fail2ban
  - Installs unattended-upgrades
- UFW (tasks/ufw.yml)
  - Reject all incoming connections by default
  - Allow all outgoing connections by default
  - Allow 22, 80, 443
- Nodejs (tasks/nodejs.yml)
- Docker (tasks/docker.yml)
- Git
- pip (Python)

Usage

Add node ip to hosts file.
```
 echo NODE_ID > hosts
```

Create new user on the droplet

 ansible-playbook -i hosts newuser.yml -u root

Enter prompt for username and public key file.

Update hosts file to reflect new user

 // hosts
 NODE_ID ansible_ssh_private_key_file=PATH_TO_PRIVATE_KEY ansible_ssh_user=USERNAME

 // Alternatively, update your ~/.ssh/config file.

Run the main play.

 // Edit to exclude/include relevant tasks.
 ansible-playbook -i hosts main.yml

TODO

Add more tasks to install various things/dependencies
