⚙️ DevOps Simplified: Automating Fullstack Deployment with Ansible in Under 5 Minutes

🧩 Overview

In the dynamic world of DevOps, repeatable infrastructure is gold. A few days ago, I faced a challenge as a DevOps engineer: wipe a cluttered VPS and redeploy a fullstack application on Hostinger from scratch. Instead of falling into the manual trap, I decided to automate everything using Ansible, the lightweight yet powerful automation engine.

This article walks through a real-world DevOps story—how I went from a messy server to a fully provisioned, production-ready environment in minutes, using Ansible playbooks.

🚀 Why Use Ansible?

Ansible is an open-source IT automation tool designed for configuration management, application deployment, and orchestration. What makes it stand out?

✅ Agentless (no software required on the server)
✅ Simple YAML syntax (human-readable)
✅ Powerful at scale (from 1 server to 10,000+)

🛠️ Prerequisites

You’ll need:

• A local machine with Ansible installed

• A remote VPS (e.g., Hostinger KVM server) with SSH or password access

• SSH communication between master and host must work

  ⚠️ If your server uses a private IP (e.g., behind a NAT or firewall), or you're on a different network, you may need a VPN to establish connectivity.
  Ensure that your master machine can ssh into the host — otherwise, Ansible playbooks will not execute.

🏗️ Step 1: Installing Ansible

On Ubuntu / Debian:

sudo apt update && sudo apt install ansible -y

On Arch Linux / EndeavourOS:

sudo pacman -S ansible

On macOS:

brew install ansible

Verify the installation:

ansible --version

📡 Step 2: Define Your Inventory

Create an inventory file to define your remote servers:

# inventory/hosts.yml
all:
  hosts:
    appserver:
      ansible_host: 1.2.3.4
      ansible_user: root
      ansible_ssh_pass: "your_password"
  children:
    webservers:
      hosts:
        appserver:

📝 You can later switch to SSH keys or add multiple servers here for mass deployments.

📶 Step 3: Test Connectivity

Let’s ensure Ansible can communicate with your server:

# ping.yml
- name: Test server connectivity
  hosts: webservers
  gather_facts: false
  tasks:
    - name: Ping the server
      ansible.builtin.ping:

    - name: Confirm reachability
      ansible.builtin.debug:
        msg: "Server is reachable and ready!"

Run the playbook:

ansible-playbook -i inventory/hosts.yml ping.yml

✅ You should see a success response—Ansible is ready to roll!

---

📦 Step 4: Bootstrap the Server with Essential Tools

Now, let’s install Git, Docker, and other useful packages:

# playbooks/bootstrap.yml
- name: Install essential DevOps tools
  hosts: webservers
  become: yes
  tasks:
    - name: Update APT cache
      ansible.builtin.apt:
        update_cache: yes

    - name: Install core packages
      ansible.builtin.apt:
        name:
          - git
          - curl
          - ca-certificates
          - gnupg
          - lsb-release
        state: present

    - name: Add Docker’s GPG key
      ansible.builtin.apt_key:
        url: https://download.docker.com/linux/ubuntu/gpg
        state: present

    - name: Add Docker repo
      ansible.builtin.apt_repository:
        repo: "deb [arch=amd64] https://download.docker.com/linux/ubuntu {{ ansible_distribution_release | lower }} stable"
        state: present

    - name: Install Docker and Compose
      ansible.builtin.apt:
        name:
          - docker-ce
          - docker-ce-cli
          - containerd.io
          - docker-compose-plugin
        state: latest

    - name: Add user to docker group
      ansible.builtin.user:
        name: "{{ ansible_user }}"
        groups: docker
        append: yes

Run it:

ansible-playbook -i inventory/hosts.yml playbooks/bootstrap.yml

⏱️ In under 4 minutes, your server is ready to host applications.

🚀 Step 5: Deploy the Fullstack Application

Here’s a playbook to clone your GitHub repo and run docker compose up.

# playbooks/deploy.yml
- name: Deploy fullstack app
  hosts: webservers
  become: yes
  vars:
    project_dir: /opt/fullstack-app
    repo_url: https://github.com/your/repo.git
  tasks:
    - name: Ensure project directory exists
      ansible.builtin.file:
        path: "{{ project_dir }}"
        state: directory
        mode: '0755'

    - name: Clone repository
      ansible.builtin.git:
        repo: "{{ repo_url }}"
        dest: "{{ project_dir }}"
        force: yes

    - name: Start app with Docker Compose
      ansible.builtin.shell: docker compose up -d
      args:
        chdir: "{{ project_dir }}"

Run the deployment:

ansible-playbook -i inventory/hosts.yml playbooks/deploy.yml

🎯 Boom! You now have a working fullstack app up and running.

📁 BONUS: Copy Local Files to the Server

Sometimes you need to ship custom config files or scripts with your playbooks.

Step 1: Create a files/ directory

mkdir -p files
echo "ENV=production" > files/.env

Step 2: Add a copy task in your playbook

- name: Copy .env file to server
  ansible.builtin.copy:
    src: files/.env
    dest: "{{ project_dir }}/.env"
    owner: root
    group: root
    mode: '0644'

You can also copy whole folders:

- name: Copy scripts directory
  ansible.builtin.copy:
    src: files/scripts/
    dest: "{{ project_dir }}/scripts/"
    owner: root
    group: root
    mode: '0755'
    recurse: yes

🛡️ This ensures all custom files are shipped with your deployment—secure, consistent, and version-controlled.
