四、在k8s中使用harbor仓库  
修改每个node上的docker认证仓库

将每个node节点上的docker同样需要配置可信任仓库

vi /etc/docker/daemon.json

\#修改为  
\{"registry-mirrors": \["http://a58c8480.m.daocloud.io"\],  
"insecure-registries": \["10.1.210.33"\]\} (harbor地址)

\#重启docker  
systemctl restart docker

复制代码  
创建认证secret  
　　由于harbor采用了用户名密码认证，所以在镜像下载时需要配置sercet

\#创建  
kubectl create secret docker-registry registry-secret --namespace=default \\  
\--docker-server=10.1.210.33 \\  
\--docker-username=admin \\  
\--docker-password=Harbor12345

\#查看secret  
\[root@master demo\]\# kubectl get secret  
NAME TYPE DATA AGE  
default-token-gdwgn kubernetes.io/service-account-token 3 2d18h  
registry-secret kubernetes.io/dockerconfigjson 1 116s

\#删除  
kubectl delete secret registry-secret

以一个部署一个nginx为例子,其中需要把containers中的images镜像指定为harbor仓库镜像地址，并且使用创建的的secret。

\# kubectl create -f nginx.yml

apiVersion: apps/v1  
kind: Deployment  
metadata:  
name: nginx-deployment  
labels:  
appname: nginx  
spec:  
replicas: 3  
selector:  
matchLabels:  
appname: nginx  
template:  
metadata:  
labels:  
appname: nginx  
spec:  
containers:  
\- name: nginx  
image: 10.1.210.33/project1/nginx:latest \#镜像地址  
ports:  
\- containerPort: 80  
imagePullSecrets: \#使用的secret  
\- name: registry-secret
