Ingress 部署
- Ngnix 部署（前面文章有部署过在此忽略）
kubectl create deployment nginx --image=nginx
kubectl expose deployment nginx --port=80 --target-port=80 --type=NodePort
- Ingress Nginx 部署
首先修改apiserver 启动参数vi /etc/kubernetes/manifests/kube-apiserver.yaml
把- --enable-admission-plugins=NodeRestriction修改为- --enable-admission-plugins=NodeRestriction,MutatingAdmissionWebhook,ValidatingAdmissionWebhook
打开官方部署https://kubernetes.github.io/ingress-nginx/deploy/
下载控制器wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.1/deploy/static/provider/baremetal/deploy.yaml
第一个编辑 vi deploy.yaml 搜索内容 controller:v1.1.1
minReadySeconds: 0
template:
metadata:
labels:
app.kubernetes.io/name: ingress-nginx
app.kubernetes.io/instance: ingress-nginx
app.kubernetes.io/component: controller
spec:
dnsPolicy: ClusterFirst
containers:
- name: controller
image: k8s.gcr.io/ingress-nginx/controller:v1.1.1@sha256:0bc88eb15f9e7f84e8e56c14fa5735aaa488b840983f87bd79b1054190e660de
#上面image修改为下面image
image: registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:v1.1.1
imagePullPolicy: IfNotPresent
lifecycle:
preStop:
exec:
command:
- /wait-shutdown
args:
- /nginx-ingress-controller
阿里云镜像登录搜索 https://cr.console.aliyun.com/cn-hangzhou/instances/images
google_containers/nginx-ingress-controller
第二个编辑 vi deploy.yaml 搜索内容 kube-webhook-certgen:v1.1.1
image: k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660
改成
image: registry.cn-hangzhou.aliyuncs.com/google_containers/kube-webhook-certgen:v1.1.1
注意：有两个相同的地方都需要修改
k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1
第三个编辑 vi deploy.yaml 搜索内容 Deployment
