Ansible-Tutorials / ansible-install-docker

Playbook used to install Docker on AWS EC2 using a basic Ansible yml file. It's will ensure Docker daemon is running and update all packages on the system

Installing Docker on AWS EC2 instance

Let's check how we can use and install Docker on EC2 instance.

1. First of all create your inventory file on /etc/ansible:

> /etc/ansible/hosts

Add your machines on inventory file

2. Now you can check if the host is accessible using ping module:

$ ansible local -m ping
localhost | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}

3. Enjoy the Ansible playbook to install the Docker on EC2:
