Deploying Applications on Kubernetes

Deploying applications on Kubernetes allows you to manage and scale containerized applications efficiently. Kubernetes automates deployment processes, ensuring applications are resilient, easily updated, and capable of handling variable workloads.

Key Concepts

• Deployments
  A Deployment in Kubernetes defines the desired state for an application, including the number of replicas, update strategy, and container specifications. Deployments enable rolling updates, ensuring smooth upgrades with minimal downtime.

• Services
  Kubernetes Services expose applications to external or internal traffic, allowing communication between Pods and users. Services provide a stable network endpoint for applications, regardless of changes in Pods.

• ConfigMaps and Secrets
  ConfigMaps store non-sensitive configuration data, while Secrets handle sensitive data like passwords and API keys. These resources decouple configuration from code, making applications more flexible and secure.

• Namespaces
  Namespaces allow you to segment resources within a Kubernetes cluster. They are useful for organizing resources, managing access control, and isolating environments (e.g., development, staging, production).

• Ingress
  Ingress resources manage external access to applications, providing routing, load balancing, and SSL termination. Ingress is crucial for exposing HTTP/HTTPS routes to services within the cluster.

Why Deploy on Kubernetes?

Kubernetes streamlines the deployment, scaling, and maintenance of containerized applications, offering tools for high availability, quick rollbacks, and automated scaling. Mastering Kubernetes deployments allows you to deliver applications reliably and efficiently.
