Kubernetes Engine

Descriptions:

• CaaS, acts as a Control Plane for Kubernetes
• Google Cloud’s load-balancing for GCP Virtual machines
• node pools to designate subsets of nodes within a cluster for additional flexibility
• Use GCP Marketplace for GKE templates
• In GKE, the load balancer is created as a network load balancer.
• Provide credentials
  • gcloud container cluster get-credentials [CLUSTER_NAME] --region [REGION_NAME]
  • only credentials for 1 cluster can be stored at a time
• kubectl config view
• gcloud container clusters
  • gcloud container clusters create bootcamp --machine-type e2-small --num-nodes 3
• Features:
  • Horitzontal Pod Autoscaler (HPA)
  • Vertical Pod Autoscaler (VPA)
  • Cluster Autoscaler (CA)
  • Node Auto Provisioning (NAP)

Costs:

• Pay for:
  • managed service
  • resources
  • networking
• There are a lot of add-ons, can be removed

Google Cloud Marketplace for GKE

1. Overview:

2. cluster

• Create Autopilot cluster:
  • auto manage:
    • Nodes: Automated node provisioning, scaling, and maintenance
    • Networking: VPC-native traffic routing for public or private clusters
    • Security: Shielded GKE Nodes and Workload Identity
    • Telemetry: Cloud Operations logging and monitoring
  • Only pays for pods, not nodes
  • No ssh
  • no priviledge escalation
• Create Standard cluster:
  • s

3. Workloads

• Deployment:
  • K8s deployment
  • Auto generate yaml file
  • Can check the events of the control plane
• Job
