1️⃣.𝙄𝙢𝙖𝙜𝙚𝘽𝙖𝙘𝙠𝙋𝙪𝙡𝙡𝙊𝙛𝙛 :-
We face this issue when the image is not present in registry or the given image tag is wrong.
Make sure you provide correct registry url, image name and image tag.
We might face authentication failures, when image is being stored in a private registry, make sure to create secret with private registry credentials and add created secret in Kubernetes Deployment File to pull docker image.
2️⃣.𝘾𝙧𝙖𝙨𝙝𝙇𝙤𝙤𝙥𝘽𝙖𝙘𝙠𝙊𝙛𝙛 :-
We face this issue when the process deployed inside container not running then the POD will be moved to CrashLoopBackOff.
POD might be running out of CPU or memory, POD should get enough resources allocated that’s cpu and memory for an application to be up and running, to fix that check in Resources Requests and Resources Limits.
3️⃣.𝙊𝙊𝙈 𝙆𝙞𝙡𝙡𝙚𝙙 - 𝙊𝙪𝙩 𝙊𝙛 𝙈𝙚𝙢𝙤𝙧𝙮 :-
We face this issue when PODs tries to utilise more memory than the limits we have set.
We can resolve it by setting appropriate resource request and resource limit.
4️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙋𝙚𝙣𝙙𝙞𝙣𝙜 :-
When nodes might not be ready and required resources like CPU and Memory may not be available in nodes for the PODs to be up and running.
5️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙒𝙖𝙞𝙩𝙞𝙣𝙜 :-
POD will be scheduled to a node but POD won’t be running in scheduled node.
We can fix this by providing correct image name, image tag and authentication to registry.
6️⃣.𝙋𝙊𝘿 𝙬𝙞𝙡𝙡 𝙗𝙚 𝙪𝙥 𝙖𝙣𝙙 𝙧𝙪𝙣𝙣𝙞𝙣𝙜 𝙖𝙣𝙙 𝙖𝙥𝙥𝙡𝙞𝙘𝙖𝙩𝙞𝙤𝙣 𝙞𝙨 𝙣𝙤𝙩 𝙖𝙘𝙘𝙚𝙨𝙨𝙞𝙗𝙡𝙚.
We can fix this by creating appropriate service.
If service is already created and application is still not accessible, make sure application and service are deployed in same namespace.
7️⃣.𝙋𝙊𝘿 𝙎𝙩𝙖𝙩𝙪𝙨 – 𝙀𝙫𝙞𝙘𝙩𝙚𝙙 :-
We can resolve this by setting appropriate resource requests and resource limits for the PODs and having enough resources in worker nodes.

📢 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:

🚀 Embrace Microservices on Azure Kubernetes Service (AKS) 🌐
Looking to harness the power of microservices in the cloud? Azure Kubernetes Service (AKS) offers an ideal platform. Here's a snapshot of this architecture:
🎯AKS: Managed Kubernetes cluster hosted in Azure. Focus on agent nodes while Azure handles the Kubernetes API service.
🎯Virtual Network: AKS sets up a virtual network for agent nodes. For advanced scenarios, set up your own network with control over subnet config and more.
🎯Ingress: Exposes HTTP(S) routes to services within the cluster, acting as an API Gateway.
🎯Azure Load Balancer: Routes internet traffic to the ingress controller, ensuring scalability and reliability.
🎯External Data Stores: Microservices often use external data stores like Azure SQL Database or Azure Cosmos DB for stateful operations.
🎯 Microsoft Entra ID: Used for creating and managing Azure resources and recommended for user authentication in client apps.
🎯Azure Container Registry: Store private Docker images for deployment. AKS can authenticate using its Microsoft Entra identity.
🎯Azure Pipelines: Part of Azure DevOps, automates builds, tests, and deployments. Also compatible with third-party CI/CD tools.
🎯Helm: A Kubernetes package manager that simplifies managing and deploying applications.
🎯Azure Monitor: Collects and stores metrics, logs, and telemetry data for monitoring, alerting, and root cause analysis.
🎯 Cost Optimization: Use the Azure pricing calculator to estimate costs, and refer to the Azure Well-Architected Framework for further insights.
🆘 Cost Considerations:
✔️ AKS: No direct cost, but you pay for underlying resources.
✔️ Azure Load Balancer: Charges for configured load-balancing rules.
✔️ Azure Pipelines: Free options with charges for extra jobs.
✔️ Azure Monitor: Costs based on data ingestion and retention.
Seize the potential of microservices on AKS, backed by the Azure cloud's robust infrastructure.
