将Maven存储库挂载到Docker [英] Mounting Maven Repository to Docker

问题描述

我正在尝试构建一个Java应用程序并使用docker制作一个软件包.这个构建需要一个Maven存储库，因为它很大，所以我不想包含在映像中.我想尝试使用卷并将本地maven存储库安装到映像中的maven存储库.为了使maven可用，我使用了 apt-get install -y maven ，但是在图像 $ HOME 中找不到目录 .m2 .代码>.

I am trying to build a Java application and make a package using docker. This builds needs a maven repository which I don't want to include in the image, since it's very large. I wanted to try using volumes and mount my local maven repository to the maven repository in the image. I used apt-get install -y maven in order to have maven available, but I can't find the directory .m2 in the image $HOME.

我用 ls -la $ HOME ， ls -la 和 ls -la/root 查找行家，但是有那里没有 .m2 目录.

I used ls -la $HOME, ls -la and ls -la /root to find the maven home, but there is no .m2 directory there.

我在 Dockerfile 中有以下几行:

FROM ubuntu
MAINTAINER Zeinab Abbasimazar
# Install and configure required packages
RUN apt-get update; \
    apt-get install -y --no-install-recommends apt-utils; \
    apt-get install -y dialog; \
    apt-get install -y wget unzip curl maven; \
    mkdir $HOME/.m2/; \
    ls -la /usr/share/maven/conf/; \
    echo \
    "<settings xmlns='http://maven.apache.org/SETTINGS/1.0.0\' \
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' \
    xsi:schemaLocation='http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd'> \
        <localRepository>/root/.m2/repository</localRepository> \
        <interactiveMode>true</interactiveMode> \
        <usePluginRegistry>false</usePluginRegistry> \
        <offline>false</offline> \
    </settings>" \
    > /usr/share/maven/conf/settings.xml
VOLUME ["/home/zeinab/.m2/", "/root/.m2/"]
# Build
RUN mvn  -X clean install -pl components -P profile

将本地存储库配置放在映像的maven配置文件中，将本地maven存储库挂载到映像中的目录，最后执行构建.正如我在Maven构建日志中看到的那样，它正在使用我期望的本地存储库路径:

Which puts local repository configurations in image's maven configuration file, mounts my local maven repository to a directory in the image and finally performs the build. As I can see in the maven build log that it's using the local repository path I expected:

[DEBUG] Reading global settings from /usr/share/maven/conf/settings.xml
[DEBUG] Reading user settings from /root/.m2/settings.xml
[DEBUG] Using local repository at /root/.m2/repository

但是仍然无法检测到依赖关系.

But still can't detect dependencies.

推荐答案

我终于找到了在docker中挂载本地maven存储库的解决方案.我改变了解决方案；我将其安装在 run 阶段，而不是 build 阶段.这是我的 Dockerfile :

I finally found the solution for mounting my local maven repository in docker. I changed my solution; I am mounting it in the run phase instead of build phase. This is my Dockerfile:

FROM ubuntu
MAINTAINER Zeinab Abbasimazar
ADD gwr $HOME
RUN apt-get update; \
    apt-get install -y --no-install-recommends apt-utils; \
    apt-get install -y wget unzip curl maven git; \
    echo \
    "<settings xmlns='http://maven.apache.org/SETTINGS/1.0.0\' \
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' \
    xsi:schemaLocation='http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd'> \
        <localRepository>/root/.m2/repository</localRepository> \
        <interactiveMode>true</interactiveMode> \
        <usePluginRegistry>false</usePluginRegistry> \
        <offline>false</offline> \
    </settings>" \
    > /usr/share/maven/conf/settings.xml; \
    mkdir /root/.m2/; \
    echo \
    "<settings xmlns='http://maven.apache.org/SETTINGS/1.0.0\' \
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' \
    xsi:schemaLocation='http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd'> \
        <localRepository>/root/.m2/repository</localRepository> \
        <interactiveMode>true</interactiveMode> \
        <usePluginRegistry>false</usePluginRegistry> \
        <offline>false</offline> \
    </settings>" \
    > /root/.m2/settings.xml
WORKDIR .
CMD mvn  -X clean install -pl components -P profile

首先，我使用上面的 Dockerfile 构建映像:

At first, I build the image using above Dockerfile:

sudo docker build -t imageName:imageTag .

然后，我运行如下容器:

Then, I run a container as below:

sudo docker run -d -v /home/zeinab/.m2/:/root/.m2/ --name containerName imageName:imageTag
