This repository contains an Ansible playbook and role to install and configure Docker and Docker Compose on both Ubuntu and CentOS systems.

The goal of this project is to provide a reusable, production-ready Ansible setup that:

• Installs Docker CE and Docker Compose.
• Supports Ubuntu (Debian family) and CentOS (RedHat family).
• Uses idempotent tasks and handlers for services.
• Can be extended with monitoring, Kubernetes, and other DevOps tools.

##  Supported Platforms

- Ubuntu (Debian-family)
- CentOS / RHEL (RedHat-family)

##  Usage

1. Clone the repository:
```bash
git clone https://github.com/Palachev/ansible-docker.git
cd ansible-docker

2. Edit inventory.ini to define your target hosts:

[linux]
ubuntu1 ansible_host=<IP_ADDRESS>
ubuntu2 ansible_host=<IP_ADDRESS>
centos1 ansible_host=<IP_ADDRESS>
Run the playbook:

3. Run the playbook:

ansible-playbook -i inventory.ini roles.yml --ask-become-pass

• --ask-become-pass will prompt for the sudo password.

• The playbook detects the OS family and executes appropriate tasks automatically.

You can modify default variables in roles/docker/defaults/main.yml: docker_version

docker_compose_version

Repository URLs, etc.

✅ Handlers Tasks notify the handler Restart docker whenever Docker is installed or updated. The handler runs only when changes occur, ensuring idempotent behavior.

💡 Extending the Playbook This role can be extended to:

Add monitoring (Grafana, Prometheus)

Deploy Kubernetes clusters

Automate container migrations

Configure alerts and backups
