📢 DevOps Project-23: ☁️ DevSecOps: Blue-Green Deployment of Swiggy-Clone on AWS ECS with AWS Code Pipeline


🔗 Project Link: HERE

📶 Project Overview :-
To demonstrate Blue-Green deployment, we’ll use AWS ECS to host our Swiggy-clone application. ECS is a highly scalable container orchestration service provided by AWS.

➡️Implementing Blue-Green Deployment with AWS CodePipeline:
AWS CodePipeline is a fully managed continuous integration and continuous delivery (CI/CD) service that automates the build, test, and deployment phases of your release process. Let’s see how to set up a Blue-Green deployment pipeline using AWS CodePipeline:
🔢. Source Stage: Connect your CodePipeline to your source code repository (e.g., GitHub). Trigger the pipeline when changes are detected in the repository.
🔢. Build Stage: Use AWS CodeBuild to build your Swiggy-clone Docker image from the source code. Run any necessary tests during this stage.
🔢. Deploy Stage: Configure AWS CodeDeploy for ECS to manage the deployment of your application to ECS clusters. Here’s where Blue-Green deployment strategy comes into play:

Linux 🐧File Permissions Explained

Linux file 💻 permissions are crucial for system security and management. Here's a quick overview to help you understand how they work.

Each file and directory in Linux has a set of permissions that determine who can read, write, or execute them. These permissions are represented by a string of characters, such as -rwxr-xr--.

➡️The permissions string is divided into 4 parts:

1. File Type: The first character indicates the type of file. A dash - means it's a regular file, while d denotes a directory.
2. Owner Permissions: The next three characters show the owner's permissions. In rwx, r stands for read, w for write, and x for execute.
3. Group Permissions: The following three characters represent the group's permissions.
4. Others Permissions: The last three characters indicate the permissions for all other users.

➡️Permissions can also be represented numerically using a three-digit code:
- 4 for read (r)
- 2 for write (w)
- 1 for execute (x)

Each digit sums the permissions for the owner, group, and others. For example, 755 translates to:
- Owner: rwx (4+2+1=7)
- Group: r-x (4+1=5)
- Others: r-x (4+1=5)

Use the chmod command to change permissions. For example, chmod 755 filename sets the file permissions to rwxr-xr-x.

➡️Key Takeaways

- Read (r): View file contents.
- Write (w): Modify file contents.
- Execute (x): Run the file as a program.

Understanding and managing file permissions is vital for maintaining system security and ensuring proper access control. Make sure you regularly check and update permissions to keep your Linux environment secure.

📣 ReplicaSet and Deployment :

ReplicaSet and Deployment are both Kubernetes resources used for managing and scaling application instances, but they serve different purposes and have distinct features:

🔖 ReplicaSet:
➡️A ReplicaSet ensures that a specified number of pod replicas are running at any given time.
It is a lower-level controller in Kubernetes.
It does not support declarative updates or rollback strategies.
➡️When using a ReplicaSet, you manage updates manually by creating new ReplicaSets with updated configurations and then deleting the old ReplicaSets.
It is often used directly only in advanced scenarios where finer control over scaling and updates is required.

🔖 Deployment:
➡️A Deployment is a higher-level resource that manages ReplicaSets and provides declarative updates and rollback strategies.
It is a higher-level abstraction built on top of ReplicaSets.
➡️Deployments allow you to describe the desired state of your application, and Kubernetes handles the process of creating and managing the ReplicaSets to achieve that state.

If you're a DevOps fresher looking to understand Azure Cloud, here's a brief introduction:


1⃣. Understanding DevOps:
- DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to improve collaboration, automate processes, and enhance software delivery.
- It emphasizes continuous integration, continuous delivery, and infrastructure as code.
- DevOps aims to break down silos between development and operations teams, fostering a culture of collaboration and agility.


2⃣. Key Concepts in DevOps:
➡️Agile Planning and Lean Project Management: Agile methodologies help manage work efficiently, while lean principles minimize waste.
➡️Version Control: Use tools like Git to manage code changes and collaborate effectively.
➡️Continuous Integration (CI): Automate code integration and testing to catch issues early.
➡️Continuous Delivery (CD): Automate deployment to ensure reliable and frequent releases.
➡️Infrastructure as Code (IaC): Define infrastructure using code (e.g., ARM templates in Azure).
➡️Monitoring and Logging: Monitor applications and infrastructure to identify issues promptly.
➡️Validated Learning: Use data and feedback to improve processes continuously.


3⃣. Building a DevOps Culture:
- Cultivating a DevOps culture involves more than just tools. It requires changes in team structures, workflows, and habits.
- Encourage collaboration, transparency, and shared responsibility.
- Focus on learning, adaptability, and continuous improvement.


⚠️ Remember, DevOps is about people, processes, and tools working together to deliver high-quality software efficiently. If you'd like to explore further, check out the Microsoft Azure DevOps tutorial for practical steps! 🚀 [1]

What is DevOps ♾ - Explained in Details

✅ We will start from the very beginning, when the software development was hard, and developers had to do everything on their own, and developing a simple app, took years.
📝 Developing software required at least two teams, developers (programmers) and the operations team.
📝 Developers had to plan, design and build the software, whereas the operations team, took the already built software, created the infrastructure and implemented the software there.

🚨 kubectl Command: Behind the scenes!

When you perform kubectl apply, Kubernetes executes a series of steps to manage the desired state of the resources defined in the provided configuration files. Here’s on what happens:

1️⃣. User issues the kubectl apply -f request.

2️⃣. The kubectl tool sends an API request to the Kubernetes API server to create or update the resource.

3️⃣. The server validates the user’s request. If all looks good, the server will write the new or modified resource into etcd.

4️⃣. The kube-controller-manager is a daemon that continually watches the kube-apiserver.

5️⃣. It will be notified of the new deployment and proceeds to create new pods to achieve the desired state through another call to the kube-apiserver.

6️⃣. Then we have kube-scheduler which is responsible for scheduling Kubernetes pods on worker nodes.

7️⃣. The kube-scheduler is then notified about the new pods that have been created and proceeds to determine which nodes are valid placements for the same. The scheduler’s primary task is to identify the create request and choose the best node for a pod that satisfies the requirements.

8️⃣. Finally, Kubelet is an agent component that runs on every node in the cluster that gets notified if a pod has been assigned to it. The assigned node then coordinates with the container runtime on the node to start the appropriate containers.
