Ansible 101 - Get It Started

Step 1 of 3

Step 1

Ansible is a simple IT automation engine for configuration management and orchestration. It can automates cloud provisioning, system configuration, application deployment and much more.

Initialize workspace

Ansible needs to be installed on the control node. Packages are available for Ubuntu 16.04+, CentOS 7 and more distributions.

First add package repository for latest release: until apt-add-repository -y ppa:ansible/ansible; do sleep 3; done

After that install Ansible: apt-get update && apt-get install -y ansible

When executed, Ansible will lookup for target host that are listed in inventories. We will cover inventories in another tutorial. Let's start with a simple form of an inventory for now. After installation, there's an example inventory file you can reference at /etc/ansible/hosts. Move the default one so we can reference it later.

mv /etc/ansible/hosts /etc/ansible/hosts.default

Now create a hosts inventory file simply looked like this:

cat << ... > /etc/ansible/hosts
[local] ansible_connection=local

Now you can test your inventory. Simply ping all nodes for this. ansible all -m ping
