☸️Kubernetes

NEW

Also known as: K8s

An open-source platform that automates deployment, scaling, and management of containerized applications across clusters.

DESCRIPTION

Kubernetes schedules and orchestrates containers across nodes, providing declarative configuration for workloads and services. It standardizes scaling, rolling updates, self-healing, and service discovery. Extensibility via operators, CRDs, and the API enables complex platforms. Ecosystem tools like Helm, Istio, and Prometheus integrate with Kubernetes for packaging, service meshes, and observability. Kubernetes underpins modern microservices, data platforms, and ML deployment pipelines across clouds and on-premises.

TOP QUESTIONS

Why use Kubernetes in data and ML platforms?

It standardizes deployment, scaling, and resource management for services and batch jobs, enabling reproducibility and portability across environments.

Category: Relevancy

How does Kubernetes help with reliability?

Self-healing restarts failed containers, health checks manage rollouts, and declarative desired state ensures consistency.

Category: Example

What are common mistakes when adopting Kubernetes?

Ignoring observability, overcomplicating with too many operators, and underestimating access control and multi-tenant isolation.

Category: Mistakes

What is a risk of running Kubernetes at scale?

Complexity can increase operational overhead; misconfiguration may lead to security exposures or resource inefficiencies.

Category: Risks

How does Kubernetes compare to Docker Swarm or Nomad?

Kubernetes has broader ecosystem and features; Swarm and Nomad offer simpler models with different trade-offs.

Category: Alternatives

Where to start learning Kubernetes?

Begin with official docs and tutorials, then practice deploying workloads using Minikube or managed services like GKE or AKS.

Category: Requirements

How does Kubernetes integrate with CI/CD?

Use pipelines to build images, push to registries, and apply manifests via GitOps tools like Argo CD or Flux.

Category: Topic

Is Kubernetes suitable for stateful workloads?

Yes, with StatefulSets, persistent volumes, and operators, though design requires careful storage and failure handling.

Category: Opinion

What observability tools are common with Kubernetes?

Prometheus, Grafana, OpenTelemetry, and Kubernetes events/metrics provide comprehensive telemetry and alerting.
