Insights
- Kubernetes, an open-source system for automating deployment and management of containerized applications, is essential for software developers, DevOps engineers, and support engineers, designed for massive scale and offering features like auto-scaling, scheduling, and self-healing.
- The workshop covers Kubernetes basics, including pods, deployments, networking, authentication, secrets, and local setup, emphasizing the importance of Kubernetes for managing containers at scale and eliminating manual tasks.
- Kubernetes architecture involves the API server, controller manager, scheduler, and kubelet to execute user commands, with commands stored in etcd for cluster state, requiring three etcd nodes for high availability and leader election.
- YAML files in Kubernetes use specific syntax like dashes for lists, pipes for multi-line strings, and placeholders for environment variables, crucial for defining objects, metadata, and specifications in Kubernetes resources.
- Kubernetes namespaces isolate environments for different teams, aiding in resource organization, team isolation, and policy enforcement, with commands like `kubectl create namespace` and `kubectl delete namespace` for management.
