➡️ How do companies ship code to production?

The diagram above illustrates the typical workflow.

➡️Step 1: The process starts with a product owner creating user stories based on requirements.

➡️Step 2: The dev team picks up the user stories from the backlog and puts them into a sprint for a two-week dev cycle.

➡️Step 3: The developers commit source code into the code repository Git.

➡️Step 4: A build is triggered in Jenkins. The source code must pass unit tests, code coverage threshold, and gates in SonarQube.

➡️Step 5: Once the build is successful, the build is stored in artifactory. Then the build is deployed into the dev environment.

➡️Step 6: There might be multiple dev teams working on different features. The features need to be tested independently, so they are deployed to QA1 and QA2.

➡️Step 7: The QA team picks up the new QA environments and performs QA testing, regression testing, and performance testing.

➡️Steps 8: Once the QA builds pass the QA team’s verification, they are deployed to the UAT environment.

➡️Step 9: If the UAT testing is successful, the builds become release candidates and will be deployed to the production environment on schedule.

➡️Step 10: SRE (Site Reliability Engineering) team is responsible for prod monitoring.

▶️ Bloated vs. Optimized Docker 🐬 Image

Let’s talk Docker images – nobody likes them big and slow, right? I had an image that was 879MB (way too big!), and I got it down to 150MB. Here’s how I did it:

[🔢] Multi-Stage Builds – Think of this like packing only what you need. You build everything in one stage, then copy over just the essentials to the final image. This keeps things simple and small.

[🔢] Use Slim Base Images – I switched to node:14-slim, which has everything you need to run the app but without the extra stuff. It made a big difference.

[🔢] Clean Up as You Go – I removed any files or packages I didn’t need after installing. Less clutter = smaller image!

[🔢] Skip Dev Dependencies – For production, you only need what’s required to run the app, not to build it. So, I left out the development tools.

[🔢] Try Alpine Images – If you’re looking to save even more, Alpine images are tiny. They need a bit more setup, but they’re worth it if you want to go super light.

Making Docker images smaller isn’t hard, and it’s worth it.

Faster builds, quicker deployments, and less storage needed. Give it a try!

The general process of using Docker. 🐬

Give it a read.

⚡️𝐃𝐨 𝐲𝐨𝐮 𝐤𝐧𝐨𝐰?

Docker emerged from dotCloud, a Platform-as-a-Service (PaaS) company.

It started as an internal project by Solomon Hykes in France, aimed at simplifying application deployment.

2013 => Docker was first unveiled at PyCon.

It quickly gained popularity due to its innovative approach to containerization.

Docker was released as open-source in March 2013.

⚡️𝐃𝐫𝐢𝐯𝐢𝐧𝐠 𝐅𝐨𝐫𝐜𝐞𝐬 -
◾️ Developer Pain Points => developers struggled with inconsistent application environments across different stages
◾️ Operational Efficiency
◾️ Cloud Adoption

Alright,

🔖 Let's understand the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐖𝐨𝐫𝐤𝐟𝐥𝐨𝐰 -

[1.] Develop
◾️ Write your application code.

[2.] Dockerfile
◾️ Create a Dockerfile that defines the environment and dependencies for your application.

[3.] Build Image
◾️ Use docker build to create a Docker image from your Dockerfile.

[4.] Run Container
◾️ Use docker run to launch a container from your image.
◾️ The container is an isolated instance of your application.

[5.] Test
◾️ Test your application within the container.
◾️ If you make changes, rebuild the image and recreate the container.

[6.] Push => This is Optional
◾️ Use docker push to share your image on a registry (e.g. Docker Hub).

[7.] Pull => This is Optional
◾️ Others can use docker pull to download your image and run your application in their own environments.

👉 Writing Ansible playbooks involves more than just defining tasks. Here are best practices to follow when creating effective and maintainable Ansible playbooks:

1. Modularity and Reusability:
Break down your playbook into smaller roles and tasks. Each role should have a specific purpose (e.g., installing packages, configuring services). This makes it easier to reuse and maintain code.
Use Ansible roles to organize your tasks. Roles allow you to encapsulate functionality and share it across different playbooks.

2. Idempotence:
Ansible playbooks should be idempotent, meaning they can be run multiple times without causing unintended changes.
Use Ansible modules that support idempotence (most built-in modules do).
Avoid using shell commands directly unless necessary.

3. Use YAML Syntax Correctly:
YAML indentation matters! Be consistent with spaces (preferably 2 spaces) and avoid tabs.
Use proper YAML syntax for lists, dictionaries, and variables.

4. Separate Variables from Playbooks:
Store variables in separate files (e.g., vars\.yml, defaults/main\.yml within roles).
Avoid hardcoding values directly in playbooks.

5. Use Descriptive Variable Names:
Choose meaningful variable names that convey their purpose.
Avoid generic names like var1, var2, etc.

6. Document Your Playbooks:
Add comments to explain the purpose of each task.
Use # for single-line comments and | for multiline comments.

7. Error Handling and Failure Conditions:
Include error handling tasks (using failed_when or ignore_errors) to gracefully handle failures.
Use block and rescue to group tasks and handle exceptions.

8. Secrets and Sensitive Data:
Use Ansible Vault to encrypt sensitive data (passwords, API keys, etc.) within playbooks.
Never hardcode secrets directly in playbooks.

9. Testing and Validation:
Test your playbooks in a safe environment (e.g., staging) before deploying to production.
Use --check mode to validate changes without applying them.

10. Inventory Management:
- Maintain a well-organized inventory file (hosts) with clear host groups.
- Use dynamic inventories if your infrastructure is dynamic (e.g., AWS, Azure).

11. Use Roles for Common Tasks:
- Create reusable roles for common tasks (e.g., setting up Nginx, configuring databases).
- Roles allow you to share functionality across different playbooks.

12. Version Control and Git:
- Store your playbooks in version control (e.g., Git).
- Commit frequently and write meaningful commit messages.

13. Testing Frameworks:
- Explore testing frameworks like Molecule or Ansible Test Kitchen for automated testing of your playbooks.

14. Performance Optimization:
- Optimize playbooks for performance by minimizing unnecessary tasks.
- Use async and poll for long-running tasks.

15. Keep Playbooks Simple:
- Avoid complex logic within playbooks. If needed, move it to custom Ansible modules or scripts.

Remember that practice and experience are key to mastering Ansible playbooks. Happy automating! 🚀🔧
