如何解決使用Maven將Docker鏡像推送到私有存儲庫時的身份驗證問題

Question

我正嘗試將我在本地使用maven構建的docker鏡像推送到Docker Cloud/Docker Hub中的公共/私有存儲庫中。但是，索引響應在嘗試Push時沒有包含任何端點.Below是我的pom.xml的示例配置。

我不知道我錯過了哪個配置。

Answer 1

打開settings.xml並添加此服務器憑據。通常這個文件位於.m2文件夾，以便在這裏添加類似：

<servers> 
    <server> 
    <id>docker-hub</id> 
    <username>username</username> 
    <password>password</password> 
    </server> 
</servers> 

此設置不應該（和AFAIK不能定）pom.xml因爲安全問題。

如果您對更安全的選項感興趣，可以像例子here那樣加密您的密碼。

你太亂了pom.xml。嘗試從最簡單的pom.xml配置開始。檢查springio example並將springio物業更改爲您的docker hub回購。

<properties> 
    <docker.image.prefix>springio</docker.image.prefix> 
</properties> 
<build> 
    <plugins> 
     <plugin> 
      <groupId>com.spotify</groupId> 
      <artifactId>docker-maven-plugin</artifactId> 
      <version>0.4.11</version> 
      <configuration> 
       <imageName>${docker.image.prefix}/${project.artifactId}</imageName> 
       <dockerDirectory>src/main/docker</dockerDirectory> 
       <serverId>docker-hub</serverId> 
<!-- <registryUrl></registryUrl> is optional and defaults to https://index.docker.io/v1/ in the Spotify docker-client dependency. --> 
       <resources> 
        <resource> 
         <targetPath>/</targetPath>

         <include>${project.build.finalName}.jar</include>
