Nexus號(hào)稱是世界上最流行的私服管理軟件(The world"s most popular repository),可以搭建幾乎目前所有常見(jiàn)的倉(cāng)庫(kù)如npm,maven,yum等,Nexus3更是增加了對(duì)docker倉(cāng)庫(kù)的支持 ,應(yīng)該是搭建私服的唯一選擇.

Nexus有兩個(gè)版本 Nexus Repository OSS和Nexus Repository Pro,其中OSS版本是免費(fèi),Pro專業(yè)版需要收費(fèi).OSS對(duì)于日常的倉(cāng)庫(kù)管理已經(jīng)足夠用.

Nexus OSS支持二進(jìn)制文件安裝和docker安裝,這里選擇docker安裝,簡(jiǎn)單方便.

運(yùn)行以下命令即可完成安裝

$ docker run -d -p 8081:8081 sonatype/nexus3
#可以掛載本地目錄做數(shù)據(jù)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倉(cāng)庫(kù)說(shuō)明文檔里掛載目錄設(shè)置的權(quán)限為200但實(shí)際安裝的時(shí)候無(wú)法啟動(dòng),權(quán)限不夠,錯(cuò)誤如下:

修改為757后正常啟動(dòng).等待啟動(dòng)完,訪問(wèn)http://host:8081測(cè)試是否安裝成功.

Nextus3倉(cāng)庫(kù)都有三種類型

hosted(本地類型)資產(chǎn)的提交和拉取都基于本地存儲(chǔ)

proxy(代理類型)本地不做數(shù)據(jù)存儲(chǔ),可以和hosted配合

group(組合類型)可以組合多個(gè)hosted和proxy并按順序,并提供統(tǒng)一訪問(wèn)地址

訪問(wèn)http://host:8081登陸,默認(rèn)用戶名密碼admin/admin123

點(diǎn)擊Repository->Blob Stores->Create blob store創(chuàng)建本地存儲(chǔ)

Type:file
Name:definesys-docker-store
Path:/nexus-data/blobs/definesys-docker-store

因?yàn)橐鎯?chǔ)鏡像請(qǐng)保證該目錄下有足夠空間,可以掛在NAS到該目錄下.

點(diǎn)擊Repositories->Create repositories->docker(hosted)創(chuàng)建本地倉(cāng)庫(kù)

Name(倉(cāng)庫(kù)名稱):definesys-docker-repo
Http(倉(cāng)庫(kù)開(kāi)放端口):8001
Docker Registry API Support:必須選上
Storage:選擇剛創(chuàng)建的definesys-docker-store
其余選項(xiàng)默認(rèn)即可

這樣就完成一個(gè)docker私有倉(cāng)庫(kù)的創(chuàng)建,過(guò)程還是很簡(jiǎn)單的.

編輯daemon.json文件

$ vi /etc/docker/daemon.json
{
    "insecure-registries": [
        "http://localhost:7001",
        "http://localhost:7002",
        "http://localhost:7003"
    ],
    "disable-legacy-registry": true
}

重啟docker

$ systemctl restart docker

啟動(dòng)Nexus3容器,將三個(gè)端口映射到主機(jī)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.分別登陸三個(gè)倉(cāng)庫(kù)

$ 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會(huì)將登陸信息記錄在~/.docker/config.json,這樣下次就不用再次登陸:

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

將本地鏡像打tag(這里以u(píng)buntu鏡像為例)上傳到hosted倉(cāng)庫(kù)(8001)

$ docker tag docker.io/ubuntu:15.10 localhost:8001/defiensys-ubuntu:15.10
$ docker push localhost:8001/defiensys-ubuntu:15.10

登陸Nexus3查看結(jié)果

通過(guò)group倉(cāng)庫(kù)

#拉取docker hub上鏡像
$ docker pull localhost:8003/mysql
#拉取私服鏡像
$ docker pull localhost:8003/defiensys-ubuntu:15.10

待續(xù)...

待續(xù)...

無(wú)法通過(guò)group上傳鏡像,報(bào)以下錯(cuò)誤

$ docker push localhost:8003/oraclelinux:v1.0
The push refers to a repository [localhost:8003/oraclelinux]
