Basic 📱 Git Flow in DevOps ♾ CI-CD!

1️⃣. Developer Creates Feature Branch: The developer creates a new feature branch and is used to work on a new feature or a specific task.

2️⃣. Developer Writes Code: The developer writes the necessary code for the feature in their local development environment.

3️⃣. Developer Commits Changes: Once the developer is satisfied with the changes, they commit the changes to the feature branch in the local Git repository.

4️⃣. Developer Creates Pull Request: The developer pushes the committed changes by creating a pull request to merge the feature branch into the main branch.

5️⃣. Code Review by Team: The pull request initiates a code review process where team members review the changes.

6️⃣. Approval of Pull Request: After addressing any feedback and making necessary adjustments, the pull request is approved by the reviewers.

7️⃣. Merge to Main Branch: The approved pull request is merged into the main branch of the Git repository.

8️⃣. Triggers CI/CD Pipeline: This automation ensures that the changes are continuously integrated and deployed.

9️⃣. Then we follow the procedure for building and testing the code, deploying to staging env. Once the tests in the staging environment pass, a manual approval is required to deploy the changes to the production environment. Once the code is deployed to production env, the prod env is monitored using Prometheus to track the performance and health of the application. The collected metrics are visualized using Grafana. Finally alerts are configured.

Fed up with the "it works on my machine" dilemma? Docker could be your salvation!

Docker revolutionizes software development and deployment by bundling your app and its dependencies into portable containers. These containers are isolated from each other, so you can run diverse apps with different settings on a single host without conflicts.

Docker containers also share the host OS kernel, making them much faster and more efficient than VMs. And because Docker is rooted in Linux, it works on Windows too, thanks to Docker Desktop for Windows.

Here are the essentials of Docker:

👉 Bundle Everything: Docker packs your app and its dependencies into a portable container, including code, runtime, tools, libraries, and settings. This makes it easy to deploy your app anywhere, on any machine.

👉 Virtual Isolation: Docker containers are isolated from each other, thanks to Linux namespaces and cgroups. This means that you can run multiple apps on the same host without worrying about conflicts.

👉 Not VMs: Docker containers share the host OS kernel, unlike VMs, which have their own kernel. This makes Docker containers much faster and more efficient.

👉 Windows Compatibility: Docker works on Windows too, thanks to Docker Desktop for Windows. This means that you can containerize your Windows apps and deploy them anywhere.

➡️ The best way to become a DevOps Engineer is to work on practical projects.

➡️ Just watching tutorials or reading ebooks will not make you employable.

➡️ You do not have a job to gain practical exposure.

➡️ Just create a cloud account and spin up a Kubernetes Cluster.

➡️ Deploy a sample application and play with it.

➡️ Then Build CI/CD pipelines using Github Actions and ArgoCD or Flux CD.

✅ Always the best approach to learning a new technology or concept is by using the technology to build something useful.
