helm install calico projectcalico/tigera-operator --version v3.22.1
watch kubectl get pods -n calico-system

安装参考:安装calico网络

安装helm

wget https://get.helm.sh/helm-v3.6.1-linux-amd64.tar.gz
tar xf helm-v3.6.1-linux-amd64.tar.gz
mv linux-amd64/helm  /usr/bin/

MetalLB

方式1: 导入yaml文件

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.12.1/manifests/namespace.yaml
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.12.1/manifests/metallb.yaml

方式2: helm

helm repo add metallb https://metallb.github.io/metallb
helm install metallb metallb/metallb
# helm install metallb metallb/metallb -f values.yaml

导入配置

kubectl apply -f -<<EOF
apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses:
      # 注意修改IP地址段
      - 20.88.9.100-20.88.9.200
EOF

Ingress

kubectl apply方式

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.1/deploy/static/provider/cloud/deploy.yaml

helm安装方式

helm upgrade --install ingress-nginx ingress-nginx \
  --repo https://kubernetes.github.io/ingress-nginx \
  --namespace ingress-nginx --create-namespace

第三方镜像库(helm)安装

helm repo add bitnami https://charts.bitnami.com/bitnami
helm install my-release bitnami/nginx-ingress-controller
# Read more about the installation in the NGINX Ingress Controller packaged by Bitnami Chart Github repository

安装完成后,会输出对应的提示,然后执行命令

kubectl get --namespace ingress-nginx svc -w ingress-nginx-ingress-controller

执行后会输出一个Service.我的Service绑定了一个LoadBalancer地址,所以将所有域名解析到这个IP.

获取ingress监听得IP地址:

    export SERVICE_IP=$(kubectl get svc --namespace ingress-nginx ingress-nginx-ingress-controller -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
    echo "Visit http://${SERVICE_IP} to access your application via HTTP."
    echo "Visit https://${SERVICE_IP} to access your application via HTTPS."

检查

kubectl get pods --namespace=ingress-nginx

ingress install
