下载nexus3镜像sonatype/nexus3,该镜像使用教程

  Status: Downloaded newer image for sonatype/nexus3:latest
  zhouchunsong@JuGuang:/home$ docker volume create --name nexus-data

运行nexus

首次启动，注意home/docker/nexus/nexus-data目录权限需要修改为200:200，对应容器内部的nexus用户，不然会因权限不足导致启动失败；8081为网页端口，8082为镜像上传下载端口

  zhouchunsong@JuGuang:/home/docker/nexus$ sudo chown -R 200:200 /home/docker/nexus/nexus-data/		
  zhouchunsong@JuGuang:/home/docker/nexus$ docker run -d -p 8081:8081 -p 8082:8082 --name nexus -v /home/docker/nexus/nexus-data:/nexus-data sonatype/nexus3

  zhouchunsong@JuGuang:/home/docker/nexus$ docker ps

修改默认端口
- 修改容器内 /nexus-data/etc/nexus.properties 文件， application-port=[your port]，这里因为和其它应用冲突，所以修改为8092。
测试工作是否正常
- 命令行检测，正常运行时会输出pong
```
  zhouchunsong@JuGuang:/home/docker/nexus$ curl -u admin:admin123 http://localhost:8081/service/metrics/ping
  pong
```
- 浏览器打开http://192.168.1.56:8092，可正常显示网页
非首次启动，执行docer start nexus

添加docker hosted仓库

访问http://192.168.1.56:8092，使用默认账号/密码:admin/admin123登录
创建docker(hosted)仓库，名称docker-hosted，注意配置http端口，这里配置为8093，与启动参数一致

修改docker启动参数

由于我们添加的本地仓库只配置了http服务，而docker默认使用https，因此在docker启动文件/etc/docker/daemon.json中添加私有仓库地址："insecure-registries":["http://192.168.1.56:8093"]，daemon.json文件内容变为：
```
  {
    "registry-mirrors": ["https://7uko0u1b.mirror.aliyuncs.com"],
    "insecure-registries":["http://192.168.1.56:8093"]
  }
```
重启docker服务：service docker restart

向本地仓库push镜像

为待上传的镜像打标签，格式为docker tag <imageId or imageName> <nexus-hostname>:<repository-port>/<image>:<tag>
