解决k8s无法拉取本地http镜像私服问题
在不同的集群都要加一下 docker的不安全 因为你不知道他会分配到哪台机器
vi /etc/docker/daemon.json

重启docker
systemctl daemon-reload
systemctl restart docker
推送docker容器镜像到harbor
docker login --usernameadmin 172.16.1.23:9010
docker login harbor所在服务器的IP:端口
输入前面注册的账号密码 [rootSR-OSDL-029 ~]# docker login --usernameyeweizheng 172.16.2.238:30020
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
[rootSR-OSDL-029 ~]#
# 不需要的情况下退出docker仓库
docker logout按照上述步骤应该是登陆成功如果失败注意检查网络账号密码防火墙等
5.推送镜像
对要推送的镜像按照格式打上tag然后docker push新tag的镜像
docker tag SOURCE_IMAGE[:TAG] 172.16.2.238:30020/test/REPOSITORY[:TAG]
docker push 172.16.2.238:30020/test/REPOSITORY[:TAG]
docker build -t hkbid:latest -f Dockerfile .
docker tag hkbid:latest 172.16.1.23:9010/hkbid/hkbid:latest
docker push 172.16.1.23:9010/hkbid/hkbid:latest
docker tag renren/fast_0517180414:latest 172.16.2.238:30020/test/renren/fast_0517180414:latest
docker tag server-gateway:latest 172.16.2.238:30020/test/server-gateway:latest
docker push 172.16.2.238:30020/test/renren/fast_0517180414
[rootSR-OSDL-029 test527]# docker tag server-gateway:latest 172.16.2.238:30020/test/server-gateway:latest
[rootSR-OSDL-029 test527]# docker images
[rootSR-OSDL-029 test527]# docker push 172.16.2.238:30020/test/server-gateway
Using default tag: latest
The push refers to repository [172.16.2.238:30020/test/server-gateway]

或者用下面标签的方式
docker pull 172.16.2.238:30020/test/server-gateway:latest
直接在dockerhub选项下 输入网址即可 6.获取镜像
不需要docker login直接docker pull 新tag的镜像即可
docker pull 172.16.2.238:30020/test/renren/fast_0517180414sha256:f3b88c731d5b4648d220ffe936cfb1e99a86d62f7e0ad745c414c3eddc54332c

以下为harbor推送镜像的命令
docker tag SOURCE_IMAGE[:TAG] 172.16.2.238:30020/test/REPOSITORY[:TAG]
docker push 172.16.2.238:30020/test/REPOSITORY[:TAG]Jenkinsfile

sh docker tag service-user:latest $REGISTRY/$DOCKERHUB_NAMESPACE/service-user:SNAPSHOT-$BUILD_NUMBER
sh docker push $REGISTRY/$DOCKERHUB_NAMESPACE/service-user:SNAPSHOT-$BUILD_NUMBER
}
