Nexus3私有仓库搭建 docker+maven+npm - yaya平台 - SegmentFault 思否

安装

Nexus号称是世界上最流行的私服管理软件(The world's most popular repository),可以搭建几乎目前所有常见的仓库如npm,maven,yum等,Nexus3更是增加了对docker仓库的支持 ,应该是搭建私服的唯一选择.

Nexus有两个版本 Nexus Repository OSS和Nexus Repository Pro,其中OSS版本是免费,Pro专业版需要收费.OSS对于日常的仓库管理已经足够用.

Nexus OSS支持二进制文件安装和docker安装,这里选择docker安装,简单方便.

运行以下命令即可完成安装

$ docker run -d -p 8081:8081 sonatype/nexus3
#可以挂载本地目录做数据持久化
$ mkdir /some/dir/nexus-data && chown -R 757 /some/dir/nexus-data
$ docker run -d -p 8081:8081 -v /some/dir/nexus-data:/nexus-data sonatype/nexus3

在nexus3官方docker仓库说明文档里挂载目录设置的权限为200但实际安装的时候无法启动,权限不够,错误如下:

mkdir: cannot create directory '../sonatype-work/nexus3': Permission denied
mkdir: cannot create directory '../sonatype-work/nexus3': Permission denied
Java HotSpot(TM) 64-Bit Server VM warning: Cannot open file ../sonatype-work/nexus3/log/jvm.log due to Permission denied

    at java.util.prefs.FileSystemPreferences.access$1200(FileSystemPreferences.java:50)
    at java.util.prefs.FileSystemPreferences$4$1.run(FileSystemPreferences.java:442)

修改为757后正常启动.等待启动完,访问http://host:8081测试是否安装成功.

Nextus3搭建docker私有仓库

Nextus3仓库都有三种类型

  1. hosted(本地类型)资产的提交和拉取都基于本地存储
  2. proxy(代理类型)本地不做数据存储,可以和hosted配合
  3. group(组合类型)可以组合多个hosted和proxy并按顺序,并提供统一访问地址

docker本地仓库(hosted)搭建

  1. 访问http://host:8081登陆,默认用户名密码admin/admin123
  2. 点击Repository->Blob Stores->Create blob store创建本地存储
Type:file
Name:definesys-docker-store
Path:/nexus-data/blobs/definesys-docker-store

因为要存储镜像请保证该目录下有足够空间,可以挂在NAS到该目录下.

  1. 点击Repositories->Create repositories->docker(hosted)创建本地仓库
Name(仓库名称):definesys-docker-repo
Http(仓库开放端口):8001
Docker Registry API Support:必须选上
Storage:选择刚创建的definesys-docker-store
其余选项默认即可

这样就完成一个docker私有仓库的创建,过程还是很简单的.

docker代理仓库(proxy)搭建

  1. 点击Repositories->Create repositories->docker(proxy)创建代理仓库
Name(仓库名称):definesys-docker-proxy
Http(仓库开放端口):8002
Docker Registry API Support:必须选上
Proxy->remote storage:https://registry-1.docker.io/
Docker index选择Use Docker Hub
Storage:选择刚创建的definesys-docker-store这样就可以和hosted共用一个存储实现本地优先本地拉取本地找不到再从远程仓库拉取
其余选项默认即可

docker组合仓库(group)搭建

Name(仓库名称):definesys-docker-group
Http(仓库开放端口):8003
Docker Registry API Support:必须选上
Storage:选择刚创建的definesys-docker-store
Group:
definesys-docker-repo
definesys-docker-proxy
其余选项默认即可

docker客户端配置

  1. 编辑daemon.json文件
$ vi /etc/docker/daemon.json
{
    "insecure-registries": [
        "http://localhost:7001",
        "http://localhost:7002",
        "http://localhost:7003"
    ],
    "disable-legacy-registry": true
}
  1. 重启docker
$ systemctl restart docker
  1. 启动Nexus3容器,将三个端口映射到主机上
$ docker run -d -p 8081:8081 -p 8001:8001 -p 8003:8003 -p 8002:8002  -v /root/u01/nexus-data:/nexus-data sonatype/nexus3

4.分别登陆三个仓库

$ docker login -u admin -p admin123 http://localhost:8001
$ docker login -u admin -p admin123 http://localhost:8002
$ docker login -u admin -p admin123 http://localhost:8003

Nexus会将登陆信息记录在~/.docker/config.json,这样下次就不用再次登陆:

{
        "auths": {
                "http://localhost:8003": {
                        "auth": "YWRtaW46YWRtaW4xMjM="
                },
                "http://localhost:8001": {
                        "auth": "YWRtaW46YWRtaW4xMjM="
                },
                "http://localhost:8002": {
                        "auth": "YWRtaW46YWRtaW4xMjM="
                }
        }
}

docker镜像上传

  1. 将本地镜像打tag(这里以ubuntu镜像为例)上传到hosted仓库(8001)
$ docker tag docker.io/ubuntu:15.10 localhost:8001/defiensys-ubuntu:15.10
$ docker push localhost:8001/defiensys-ubuntu:15.10
  1. 登陆Nexus3查看结果

docker镜像拉取

  • 通过group仓库
#拉取docker hub上镜像
$ docker pull localhost:8003/mysql
#拉取私服镜像
$ docker pull localhost:8003/defiensys-ubuntu:15.10

遗留问题

  1. 无法通过group上传镜像,报以下错误
$ docker push localhost:8003/oraclelinux:v1.0
The push refers to a repository [localhost:8003/oraclelinux]
