K8s容器初始化和负载均衡

1. 首先，在kubernetes集群中部署一个Nginx Ingress Controller，用于处理HTTP（s）流量并提供负载均衡服务。以下是yaml文件的示例：

apiVersion: extensions/v1beta1 kind: Deployment metadata: name: nginx-ingress-controller spec: replicas: 1 template: metadata: labels: app: nginx-ingress spec: nodeSelector: kubernetes.io/os: linux containers: - name: nginx-ingress-controller image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.14.0 args: - /nginx-ingress-controller - --configmap=$(POD_NAMESPACE)/nginx-configuration - --tcp-services-configmap=$(POD_NAMESPACE)/tcp-services - --udp-services-configmap=$(POD_NAMESPACE)/udp-services env: - name: POD_NAME valueFrom: fieldRef: fieldPath: metadata.name - name: POD_NAMESPACE valueFrom: fieldRef: fieldPath: metadata.namespace ports: - name: http containerPort: 80 - name: https containerPort: 443 livenessProbe: httpGet: path: /healthz port: http initialDelaySeconds: 10 timeoutSeconds: 5 readinessProbe: httpGet: path: /healthz port: http initialDelaySeconds: 10 timeoutSeconds: 5

2. 接下来，在kubernetes集群中创建一个deployment，其中包含容器需要执行的命令。以下示例使用nginx作为容器图像：

apiVersion: apps/v1 kind: Deployment metadata: name: nginx-deployment spec: replicas: 3 selector: matchLabels: app: nginx template: metadata: labels: app: nginx spec: containers: - name: nginx image: nginx:1.14-alpine ports: - containerPort
