Kubernetes

The Subtopics every developer knows or uses under Kubernetes:

Pods:

Orchestrating containerized applications, Kubernetes manages Pods as the smallest deployable units, grouping one or more containers together.

Deployments:

Ensuring application availability, Kubernetes Deployments manage the lifecycle of Pods, providing scaling, rolling updates, and rollback capabilities.

Services:

Facilitating network communication, Kubernetes Services abstract Pod access, providing stable endpoints for inter-Pod communication within the cluster.

Ingress:

Routing external traffic, Kubernetes Ingress controllers manage incoming requests, enabling HTTP and HTTPS routing based on defined rules.

Persistent Volumes:

Managing storage, Kubernetes Persistent Volumes abstract underlying storage resources, providing persistent data storage for stateful applications.

ConfigMaps and Secrets:

Configuring applications securely, Kubernetes ConfigMaps and Secrets store configuration data and sensitive information, respectively, allowing applications to consume them as environment variables or mounted files.

Namespaces:

Organizing resources, Kubernetes Namespaces partition cluster resources, enabling multi-tenancy and resource isolation within a single cluster.

Horizontal Pod Autoscaling (HPA):

Scaling applications dynamically, Kubernetes HPA automatically adjusts the number of replica Pods based on resource utilization metrics, ensuring optimal performance and cost-efficiency.

Custom Resource Definitions (CRDs) and Operators:

Extending Kubernetes functionality, CRDs define custom resources and Operators automate management tasks, enabling custom controllers for complex application orchestration.

Kubernetes StatefulSets:

Deploying stateful applications, Kubernetes StatefulSets manage stateful Pods, providing ordered deployment, scaling, and persistent network identities for databases and other stateful workloads.
