docker私服搭建nexus3

docker私服搭建有官方的registry鏡像,也有改版後的NexusOss3.x,由於maven的緣由搭建了nexus,因此一併將docker私服也搭建到nexus上。node

nexus的安裝過程就單獨說了,若是是2.x系列須要升級到2.14版本再升級到3.y系列,若是3.x到3.y直接升級就能夠。docker

從3.0版本開始,nexus再也不只是一個maven倉庫,還能夠是docker、npm、bower的私有倉庫。shell

配置SSL

docker的倉庫連接是基於HTTPS的,故通常狀況下須要將nexus的訪問方式改成支持https。
配置SSL主要的難點在於證書,證書能夠用公網證書,而通常狀況下,私服部署在內網,沒有域名,用內網IP訪問,這種狀況下用自簽名的證書是最好的選擇。證書生成工具用jdk自帶的就能夠。
配置過程,進入${nexus}/etc/ssl目錄下面,執行命令過程當中會輸入屢次密碼,記下密碼,後面有用處:npm

$ keytool -genkeypair -keystore example.jks -storepass password -alias example.com \
>  -keyalg RSA -keysize 2048 -validity 5000 -keypass password \
>  -dname 'CN=*.example.com, OU=Sonatype, O=Sonatype, L=Unspecified, ST=Unspecified, C=US' \
>  -ext 'SAN=DNS:nexus.example.com,DNS:clm.example.com,DNS:repo.example.com,DNS:www.example.com'

Warning:
The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore example.jks -destkeystore example.jks -deststoretype pkcs12".
$ keytool -exportcert -keystore example.jks -alias example.com -rfc > example.cert
Enter keystore password:  password

修改配置文件:etc/nexus.propertiesjson

原:
nexus-args=${jetty.etc}/jetty.xml,${jetty.etc}/jetty-http.xml,${jetty.etc}/jetty-requestlog.xml
修改後:
application-port-ssl=8433
nexus-args=${jetty.etc}/jetty.xml,${jetty.etc}/jetty-http.xml,${jetty.etc}/jetty-https.xml,${jetty.etc}/jetty-requestlog.xml

修改配置文件:etc/jetty/jetty-https.xml瀏覽器

<New id="sslContextFactory" class="org.eclipse.jetty.util.ssl.SslContextFactory">
    <Set name="KeyStorePath"><Property name="ssl.etc"/>/keystore.jks</Set> // 文件名和前面證書的一致
    <Set name="KeyStorePassword">password</Set> // 密碼用前面的
    <Set name="KeyManagerPassword">password</Set>

    <Set name="TrustStorePassword">password</Set>

        <Item>SSL_DHE_DSS_WITH_DES_CBC_SHA</Item>

      </Array>
    </Set>
  </New>

重啓nexus,打開瀏覽器訪問,https://ip:8443/ 會提示出來證書籤名有問題,直接略過就行。app

建立倉庫(私有,代理,組合)

建立三個倉庫,若是須要代理多個來源,能夠建立多個代理庫。
私有倉庫:注意將http或者https的端口打開。eclipse

代理中央庫的注意地址:
remote: https://registry-1.docker.io
docer index : use Docker hubmaven

組合倉庫將剛創建的Hosted和Proxy倉庫都加入就能夠了。工具

 配置docker本地

本地配置最主要的是配置insecure-registries和docker login。

配置daemon.json

/etc/docker/daemon.json

{
  "registry-mirrors": ["https://IP:18443"],
  "insecure-registries":["IP:18443","IP:18444"]
}

爲何須要兩個insecure-registry呢?由於group倉庫不能夠做爲push倉庫,若是單純的進行pull,能夠只配置一個。

docker login

分別login兩個insecure-registry。

$ docker login IP:18444
Username (admin): admin
Password: 
Login Succeeded
$ docker login IP:18443
Username (admin): admin
Password: 
Login Succeeded

這樣能夠愉快的進行push和pull操做了。

push和pull的坑

nexus有一個設定,push只能對Hosted,pull從三種倉庫均可以。由於push的操做給proxy的,是沒法推送給被代理庫的。group的倉庫接受push後,沒法肯定是給proxy仍是hosted。
可是nexus能夠經過push給hosted的倉庫,可是經過group倉庫pull。

完成。
