# Installing Docker on Servers With Ansible
|
|
|
|
## Overview
|
|
|
|
This is a simple playbook to install Docker on a server. This is really useful for getting docker installed on servers before running a dockerised workload.
|
|
|
|
## Pre-requisites
|
|
|
|
You will need ansible already installed on your machine and a ansible inventory file, check out the sample below:
|
|
|
|
```yml
|
|
playbook-hosts:
|
|
hosts:
|
|
host1:
|
|
ansible_host: <ip-address>
|
|
```
|
|
|
|
This playbook also assumes that you have a user with sudo privileges on the remote machine, and you can use ssh keys to authenticate.
|
|
|
|
## The playbook
|
|
|
|
The playbook to install docker is below:
|
|
|
|
```yml
|

|
```
|
|
|
|
::: tip
|
|
|
|
Apitude is used to install the packages as it is more reliable than apt-get, and also preferred by Ansible.
