前提條件:
- 有一臺電腦 安裝了maven
- 安裝了jdk1.8 以上版本
- 安裝了 git
- 安裝了intellij idea
- 電腦能上網
- 有一臺nexus 服務器，如果沒有可以參考我的另一篇文章:Sonatype Nexus 自動化部署實踐 https://blog.csdn.net/happyfreeangel/article/details/89481720
我的nexus 服務器器是支持https的，可以 端口是:上傳鏡像端口是1443, 下載鏡像端口是2443，
域名是nexus.linkaixin.com
spotify docker-maven-plugin 官方源代碼地址:
https://github.com/spotify/docker-maven-plugin
下面是一個大型網上商店的源代碼，用於測試鏡像打包，上傳nexus.
https://github.com/HappyFreeAngel/mall.git
git clone https://github.com/HappyFreeAngel/mall.git
cd mall
mvn clean compile package docker:build -DpushImage
實現了編譯，打包，封裝docker 鏡像，推送docker 鏡像到nexus 倉庫。
結果如下:
本地鏡像結果如下:
docker images | grep ‘nexus.linkaixin.com:1443/mall’
遠程倉庫查看： 結果如下
看起來很簡單的插件，使用起來其實坑很多。
我後來查看了源代碼，通過幾種測試方法，才發現問題所在。
需要配置的文件: 1. .m2/settings.xml

踩到的坑如下:
問題1:
[ERROR] No plugin found for prefix ‘docker’ in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/Users/linyingjie/.m2/repository), alimaven (http://maven.aliyun.com/nexus/content/groups/public/)] -> [Help 1]
解決辦法: .m2/settings.xml 添加 com.spotify

<pluginGroup>io.fabric8</pluginGroup>

問題2:

這個原因是因爲這個插件優先使用了.docker/config.json，但是這個會超時失敗，不知道是什麼原因
刪除裏面的nexus.linkaixin.com 的2條記錄，就正常了。
{
"auths": {
"nexus.linkaixin.com:1443": {},
"nexus.linkaixin.com:2443": {}
},
"HttpHeaders": {
"User-Agent": "Docker-Client/18.09.2 (darwin)"
},
"credsStore": "osxkeychain",
"stackOrchestrator": "swarm"
}
改成下面:
{
"auths": {
},
"HttpHeaders": {
"User-Agent": "Docker-Client/18.09.2 (darwin)"
},
"credsStore": "osxkeychain",
"stackOrchestrator": "swarm"
}
這個其實就是讓docker-maven-plugin 在config.json 裏找不到關於nexus.linkaixin.com賬號配置,
讓它搜索settings.xml 裏的配置賬號信息。
