1. Specialized Kubernetes Scenarios

Implementing Blue-Green Deployments

• Strategies for zero-downtime deployments.

  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: my-app-blue
  

Handling Batch Jobs and CronJobs

• Scheduling and managing batch processes.

  apiVersion: batch/v1
  kind: Job
  metadata:
    name: my-batch-job
  

Using Kubernetes in Hybrid Cloud Environments

• Integrating Kubernetes with multiple cloud providers.

  kubectl config set-context my-hybrid-cloud --cluster=cluster1
  

2. Custom Configurations and Extensions

Helm Charts for Complex Applications

• Deploying multi-component apps with Helm.

  helm install my-app-chart my-chart-repo/my-app
  

Kubernetes Operators

• Automating application management with Operators.

  kubectl apply -f my-operator.yaml
  

Advanced Networking with CNI Plugins

• Configuring network policies and plugins for advanced networking needs.

  apiVersion: networking.k8s.io/v1
  kind: NetworkPolicy
  

3. Kubernetes Cluster Administration

Upgrading and Maintaining Clusters

• Best practices for upgrading and maintaining Kubernetes clusters.

  kubectl drain node1 --ignore-daemonsets
