weeve Kubernetes

shell commands:

• Get K8s context gcloud container clusters get-credentials <cluster name>
• list kubectl contexts: kubectl config get-contexts
• set kubectl context: kubectl config use-context <context name>

Concepts:

• Pod - bundle of (Docker) containers that share a "localhost" scope
• Deployment - template definition for pods
• NodePort - service that externally exposes pods by provisioning a random "high port" (30000+)
• ClusterIP - service that internally exposes pods to each other
• Ingress - externally facing load balancer that proxies internal services
