It gives developers a consistent runtime by bundling code and dependencies.

It automates deployment, scaling, networking, and availability of containers across clusters of machines. It handles load balancing, rolling updates, and restarts failed containers automatically.<\/p>\n<h2>Docker vs Kubernetes: Not Either\/Or<\/h2>\n<p>These tools are complementary. Kubernetes uses container runtimes (often containerd, which powers Docker) to run containers. A typical workflow: build images with Docker, then deploy those images using Kubernetes.<\/p>\n<h3>Key Differences at a Glance<\/h3>\n<ul>\n<li>Scope: Docker manages individual containers; Kubernetes manages entire fleets.<\/li>\n<li>Scaling: Docker scales manually or via Compose; Kubernetes auto-scales horizontally.<\/li>\n<li>Networking: Docker uses simple port mapping; Kubernetes offers advanced service discovery and ingress.<\/li>\n<li>Self-healing: Docker restarts single containers; K8s replaces failed nodes and reschedules workloads.<\/li>\n<\/ul>\n<h2>When to Use Which?<\/h2>\n<p>Use Docker for local development, small apps, or single-host deployments. Choose Kubernetes when you need high availability, auto-scaling, and complex microservices in production.<\/p>\n<p>In summary, Docker builds containers; Kubernetes runs them at scale. Most modern cloud-native stacks use both together.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kubernetes vs Docker: Understanding the Core Differences in Containerization Docker and Kubernetes are often mentioned together, but they solve different problems.
