docker 连接私有仓库，并向私有仓库推送镜像
一、检查是否已经配置私有仓库
docker info

Docker Root Dir: /var/lib/docker
Debug Mode (client): false
Debug Mode (server): false
Registry: https://index.docker.io/v1/

# 检查此项
Insecure Registries:
127.0.0.0/8
Registry Mirrors:
https://pak31uuv.mirror.aliyuncs.com/
https://registry.docker-cn.com/
Live Restore Enabled: false
Product License: Community Engine
- Insecure Registries：表示私有仓库地址，本次案例配置的私有仓库地址为 192.168.80.135
二、配置私有仓库
2.1 编辑配置文件（不存在则新建）
vim /etc/docker/daemon.json
# 添加配置
"insecure-registries": [
"192.168.80.135"
]
2.2 配置完成的内容
{
"registry-mirrors": [
"https://pak31uuv.mirror.aliyuncs.com",
"https://registry.docker-cn.com"
],
"insecure-registries": [
"10.1.119.12"
]
}
- registry-mirrors : 配置镜像加速服务（本次案例是使用的tanxingsong的阿里云镜像加速服务，读者在配置的时候，可以自行去阿里云申请免费镜像加速服务，如果嫌麻烦，也可以先用着笔者的镜像加速）
- insecure-registries : 配置远程仓库
2.3 重启docker
systemctl restart docker
2.4 检查是否配置成功
docker info

# 如果存在 192.168.80.135 ，则说明配置成功

三、将镜像推送至私有仓库
3.1 登录私有仓库
docker login 192.168.80.135 -u admin -p Harbor12345
# 输出如下
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
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
- 出现 Login Succeeded 则说明登录成功
3.2 重命名镜像（我们自己的工程推送，项目为basic，即，镜像名应为：192.168.80.135/basic/openjdk:8）
docker tag openjdk:8 192.168.80.135/basic/openjdk:8
3.3 将镜像推送至私有仓库
docker push 192.168.80.135/basic/openjdk:8
# 输出如下
The push refers to repository [10.1.119.12/basic/openjdk]

3.4 检查镜像
