🔴 On Kubernetes platforms, traffic may come from an internal source (between workloads within the cluster), or an 𝗲𝘅𝘁𝗲𝗿𝗻𝗮𝗹 𝘀𝗼𝘂𝗿𝗰𝗲 (from an outside client to a workload in the cluster). List all objects 𝗶𝗻𝘃𝗼𝗹𝘃𝗲𝗱 𝗶𝗻 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝘁𝗿𝗮𝗳𝗳𝗶𝗰 𝗿𝗼𝘂𝘁𝗶𝗻𝗴:

✅ External Load Balancer - Distribute external traffic
✅ Ingress Controller - Responsible for implementing these rules
✅ Ingress - Incoming traffic to the pod
✅ Service - Exposing a network application
✅ Pod - Collection of one or more containers

🔴 HTTP is a protocol that enables data transmission via the world wide web, HTTPS is essentially a 𝗺𝗼𝗿𝗲 𝘀𝗲𝗰𝘂𝗿𝗲 𝘃𝗲𝗿𝘀𝗶𝗼𝗻.

🔴 SSL & TLS are the same. SSL is the old name. TLS is the 𝐮𝐩𝐝𝐚𝐭𝐞𝐝 𝐯𝐞𝐫𝐬𝐢𝐨𝐧 𝐨𝐟 𝐒𝐒𝐋.

🔴 The basic requirement for ingress TLS is a 𝗧𝗟𝗦/𝗦𝗦𝗟 𝗰𝗲𝗿𝘁𝗶𝗳𝗶𝗰𝗮𝘁𝗲. You can obtain these certificates in the following ways.

☑️ Self-Signed Certificates
☑️ Purchase an SSL Certificate
☑️ Use Letsencrpt Certificate - Non trusted certificate

𝗧𝘆𝗽𝗲𝘀 𝗼𝗳 𝗜𝗻𝗴𝗿𝗲𝘀𝘀
☑️ Single service Ingress ➡️ All traffic is routed to a single default backend.
☑️ Simple fanout Ingress ➡️ Sends traffic from a single IP address to multiple Services depending on the requested HTTP.
☑️ Name-based virtual hosting ➡️ Support steering HTTP traffic to various hostnames at a similar IP address.

🔴 A Kubernetes Secret is an object that contains a 𝘀𝗺𝗮𝗹𝗹 𝗮𝗺𝗼𝘂𝗻𝘁 𝗼𝗳 𝘀𝗲𝗻𝘀𝗶𝘁𝗶𝘃𝗲 𝗱𝗮𝘁𝗮 such as a password, a token, or a key.

🔴 When you create a secret, it needs to be referenced by the pod that will use it. To make a secret available for a pod.
✔️ Mount the secret as a file in a volume available to any number of containers in a pod.
✔️ Import the secret as an environment variable to a container.

Kubernetes Design Patterns are reusable solutions to common problems encountered when deploying applications on Kubernetes. They help in structuring and organizing applications for scalability, resilience, and maintainability. Some key Kubernetes design patterns include:

🛡 Sidecar Pattern: Involves deploying an additional container alongside the main application container to extend its functionality without altering the main container.
🛡 Ambassador Pattern: Conceals complexity by providing a unified interface to the outside world for a container, simplifying communication with external services.
🛡 Adapter Pattern: Allows a pod to present a consistent interface to the external world by transforming requests and responses as necessary.
🛡 Initialize Pattern: Separates initialization-specific tasks from the main application logic, ensuring that containers are initialized properly before serving requests.
🛡 Work-Queue Pattern: Enables the processing of arbitrary code within containers and facilitates the implementation of work-queue systems using Kubernetes primitives.
🛡 Custom-Controller Pattern: Implements custom logic to observe changes in Kubernetes objects and ensures that the cluster reaches the desired state based on these modifications.
🛡 Self-Awareness Patterns: Enable applications to gather metadata and understand their runtime environment, facilitating dynamic configuration and adaptation.

By leveraging these design patterns, developers can design more robust and scalable applications that effectively utilize the capabilities of the K8s platform.

🚨 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.
