docker安装nexus,搭建docker镜像代理仓库

一、安装Nexus

docker run -d --name nexus \
--restart=always \
--privileged=true \
-p 30024:8081 \
-p 30025:8082 \
-v /home/$USER/dockerfile/nexus/data/nexus-data:/nexus-data \
sonatype/nexus3:3.45.0

二、创建docker镜像仓库

1.创建

2.选择代理仓库

3.填写信息

4.添加docker权限

5.创建角色和用户（仅使用代理功能无需创建）

6.配置/etc/docker/daemon.json文件

{
    "registry-mirrors": [
           "https://hub-mirror.c.163.com",
           "http://10.10.11.100:30025"
        ],
        "insecure-registries": ["10.10.11.100:30025"]
}

重载配置

systemctl daemon-reload

重启docker服务

systemctl restart docker

三、测试

myuser@ubuntu:/etc/docker$ docker pull 10.10.11.100:30025/helloz/transmission:v1.3
