🚀 ansibleRoboshop: My Ansible Automation Journey 🛠️✨

Welcome! This repository showcases my hands-on automation of the Roboshop microservices stack using Ansible.
Each playbook reflects my growth, troubleshooting wins, and practical DevOps experience. 🌱

📚 How I Learned

• 📝 Official Ansible Documentation for best practices and syntax.
• 🤖 ChatGPT for debugging help and YAML tips.
• 🔍 Trial and error with MongoDB and MySQL data loading.

🗂️ What’s Inside

📦 Playbooks for Microservices & Components

• 🍃 mongodb.yaml – Install & configure MongoDB
• 🐬 mysql.yaml – Install & secure MySQL
• 🧊 redis.yaml – Setup Redis
• 🐇 rabbitmq.yaml – Setup RabbitMQ
• 📦 catalogue.yaml – Node.js app with MongoDB
• 👤 user.yaml – Node.js with MongoDB & Redis
• 🛒 cart.yaml – Node.js with Redis & Catalogue
• 🚚 shipping.yaml – Java app with MySQL
• 💳 payment.yaml – Python app with RabbitMQ
• 🌐 frontend.yaml – Nginx static frontend

🐞 Troubleshooting & Key Learnings

• Module Usage:

  • Used ansible.builtin.* modules for most tasks (install, copy, user, file, service).
  • Leveraged community.general.npm for Node.js dependencies and community.mysql.mysql_db for MySQL data import.

• Loading Data Challenges:

  • MongoDB:

    • Loading initial data required using the shell module and careful handling of command output and conditions.
    • Example:

      - name: check products loaded or not
        ansible.builtin.command: mongosh --host mongodb.srivenkata.shop --eval 'db.getMongo().getDBNames().indexOf("catalogue")'
        register: catalogue_output
      
      - name: load products
        ansible.builtin.shell: mongosh --host mongodb.srivenkata.shop < /app/db/master-data.js
        when: catalogue_output.stdout | int < 0

    • Faced issues with string/integer conversion and learned to use Jinja2 filters (| int).

  • MySQL:

    • Used community.mysql.mysql_db to import SQL files.
    • Had to ensure MySQL was running and credentials were correct.

• Common Errors & Fixes:

  • User Module:
    • Learned about system: true and create_home options for system users.
  • File Paths:
    • Used remote_src: yes for unarchiving files already present on the remote host.
  • Service Reloads:
    • Always reloaded systemd after copying new service files.

• Debugging Approach:

  • Checked Ansible output for failed tasks.
  • Used ansible.builtin.debug to print variables and outputs.
  • Searched Ansible docs and asked ChatGPT for error explanations.

🏁 How to Use This Repo

1. Clone the repository:

   git clone https://github.com/yourusername/ansibleRoboshop.git
   cd ansibleRoboshop

2. Edit inventory.ini with your hostnames.

3. Run a playbook a specific component:

ansible-playbook -i inventory.ini -e "ansible_user=<user>" -e "ansible_password=<password>" <component-playbook>.yaml

Replace <component-playbook> with e.g., catalogue.yaml. -Example 🌟

ansible-playbook -i inventory.ini -e "ansible_user=<user>" -e "ansible_password=<password>" catalogue.yaml

🌟 My Favorite Moments

• 🎉 The first time all services started without errors!
• 🐞 Debugging and finally loading data into MongoDB and MySQL.
• 🤩 Seeing the Roboshop app running end-to-end, fully automated!
