系统与环境
vmware ubuntu18
linux
docker --> 我写的教程
k3d+kubectl --> 我写的教程
配置步骤
1.创建cluster，-p参数制定将host的8081端口映射到serverlb容器上的80端口，serverlb再代理到所有的server节点的80端口上
k3d cluster create -p "8081:80@loadbalancer" --agents 2
2.部署deployment
kubectl apply -f nginx.yaml
nginx.yaml 文件内容如下图
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
labels:
app: nginx
spec:
replicas: 1
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx
ports:
- containerPort: 80
3.部署service
kubectl apply -f nginx.yaml
nginx.yaml文件如下
apiVersion: v1
kind: Service
metadata:
name: nginx
spec:
selector:
app: nginx
ports:
- protocol: TCP
port: 80
targetPort: 80
4.部署ingress
kubectl apply -f nginx.yaml
nginx.yaml内容如下
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: nginx-ingress
annotations:
ingress.kubernetes.io/ssl-redirect: "false"
spec:
rules:
- http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: nginx
port:
number: 80
-
访问 hostport:8081
检查
通过describe ing/svc等指令可以看到整体是否流通
比如describe svc，后可以看到
Endpoints: 10.****
10.**** 如果和pod ip一致，则说明配置成功
