Nexus3私有倉庫搭建 docker+maven+npm

安裝

Nexus號稱是世界上最流行的私服管理軟件(The world's most popular repository),能夠搭建幾乎目前全部常見的倉庫如npm,maven,yum等,Nexus3更是增長了對docker倉庫的支持 ,應該是搭建私服的惟一選擇.

Nexus有兩個版本 Nexus Repository OSS和Nexus Repository Pro,其中OSS版本是免費,Pro專業版須要收費.OSS對於平常的倉庫管理已經足夠用.

Nexus OSS支持二進制文件安裝和docker安裝,這裏選擇docker安裝,簡單方便.

運行如下命令便可完成安裝

$ docker run -d -p 8081:8081 sonatype/nexus3
#能夠掛載本地目錄作數據持久化
$ 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倉庫說明文檔裏掛載目錄設置的權限爲200但實際安裝的時候沒法啓動,權限不夠,錯誤以下:

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)

修改成757後正常啓動.等待啓動完,訪問http://host:8081測試是否安裝成功.

Nextus3搭建docker私有倉庫

Nextus3倉庫都有三種類型

1. hosted(本地類型)資產的提交和拉取都基於本地存儲
2. proxy(代理類型)本地不作數據存儲,能夠和hosted配合
3. group(組合類型)能夠組合多個hosted和proxy並按順序,並提供統一訪問地址

docker本地倉庫(hosted)搭建

1. 訪問http://host:8081登錄,默認用戶名密碼admin/admin123
2. 點擊Repository->Blob Stores->Create blob store建立本地存儲

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

由於要存儲鏡像請保證該目錄下有足夠空間,能夠掛在NAS到該目錄下.

1. 點擊Repositories->Create repositories->docker(hosted)建立本地倉庫

Name(倉庫名稱):definesys-docker-repo
Http(倉庫開放端口):8001
Docker Registry API Support:必須選上
Storage:選擇剛建立的definesys-docker-store
其他選項默認便可

這樣就完成一個docker私有倉庫的建立,過程仍是很簡單的.

docker代理倉庫(proxy)搭建

1. 點擊Repositories->Create repositories->docker(proxy)建立代理倉庫

Name(倉庫名稱):definesys-docker-proxy
Http(倉庫開放端口):8002
Docker Registry API Support:必須選上
Proxy->remote storage:https://registry-1.docker.io/
Docker index選擇Use Docker Hub
Storage:選擇剛建立的definesys-docker-store這樣就能夠和hosted共用一個存儲實現本地優先本地拉取本地找不到再從遠程倉庫拉取
其他選項默認便可

docker組合倉庫(group)搭建

Name(倉庫名稱):definesys-docker-group
Http(倉庫開放端口):8003
Docker Registry API Support:必須選上
Storage:選擇剛建立的definesys-docker-store
Group:
definesys-docker-repo
definesys-docker-proxy
其他選項默認便可

docker客戶端配置

1. 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
}

1. 重啓docker

$ systemctl restart docker

1. 啓動Nexus3容器,將三個端口映射到主機上

$ 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.分別登錄三個倉庫

$ 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會將登錄信息記錄在~/.docker/config.json,這樣下次就不用再次登錄:

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

docker鏡像上傳

1. 將本地鏡像打tag(這裏以ubuntu鏡像爲例)上傳到hosted倉庫(8001)

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

1. 登錄Nexus3查看結果

docker鏡像拉取

• 經過group倉庫

#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...

遺留問題

1. 沒法經過group上傳鏡像,報如下錯誤

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