Docker 安装Jenkins并配置Maven

系统环境
系统版本：Centos7.9

docker安装参考此链接：

下载docker时候如果报错参考：

一、安装Maven

因为用到的docker镜像中不包含maven，所以要在容器里安装maven，把下载好的maven包传进服务器中

1.1 把下载好的maven包传进服务器中

dfc@BBC-xxc ~ % scp /Users/dfc/Library/Containers/com.tencent.xinWeChat/Data/Library/Application\ Support/com.tencent.xinWeChat/2.0b4.0.9/8f3459f55f57e8f624ecba5da6564b5f/Message/MessageTemp/6fcb9ab864d6f647e050d2ccfc35165a/File/apache-maven-3.8.5-bin.tar.gz root@192.168.10.34:/abb 

1.2 解压

tar -xzvf apache-maven-3.8.5-bin.tar.gz

1.3 拷贝进docker 中的Jenkins容器下的/maven/目录下

[root@redis02 ~]# docker cp /abb/apache-maven-3.8.5 Jenkins:/maven/

1.4 修改国内源，配置settings.xml
新建一个settings.xml文件

vim settings.xml

写入
<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
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <localRepository/>
    <interactiveMode/>
    <usePluginRegistry/>
    <offline/>
    <pluginGroups/>
    <servers/>
    <mirrors>
        <mirror>
            <id>aliyunmaven</id>
            <mirrorOf>central</mirrorOf>
            <name>阿里云公共仓库</name>
            <url>https://maven.aliyun.com/repository/central</url>
        </mirror>
        <mirror>
            <id>repo1</id>
            <mirrorOf>central</mirrorOf>
            <name>central repo</name>
            <url>http://repo1.maven.org/maven2/</url>
        </mirror>
        <mirror>
            <id>aliyunmaven</id>
            <mirrorOf>apache snapshots</mirrorOf>
            <name>阿里云阿帕奇仓库</name>
            <url>https://maven.aliyun.com/repository/apache-snapshots</url>
        </mirror>
    </mirrors>
    <proxies/>
    <activeProfiles/>
    <profiles>
        <profile>
            <repositories>
                <repository>
                    <id>aliyunmaven</id>
                    <name>aliyunmaven</name>
                    <url>https://maven.aliyun.com/repository/public</url>
                    <layout>default</layout>
                    <releases>
                        <enabled>true</enabled>
                    </releases>
                    <snapshots>
                        <enabled>true</enabled>
                    </snapshots>
                </repository>
                <repository>
                    <id>MavenCentral</id>
                    <url>http://repo1.maven.org/maven2/</url>
                </repository>
                <repository>
                    <id>aliyunmavenApache</id>
                    <url>https://maven.aliyun.com/repository/apache-snapshots</url>
                </repository>
            </repositories>
        </profile>
    </profiles>
</settings>

替换掉原来的settings.xml文件，原来的settings.xml文件在/maven/apache-maven-3.8.5/conf/ 下

[root@redis02 ~]# docker cp settings.xml jenkins:/maven/apache-maven-3.8.5/conf/ #同样的文件名，会覆盖掉之前的

在容器中进入

root@38d0cecdc58b:/etc# ls /maven/apache-maven-3.8.5/bin/

验证maven安装

root@38d0cecdc58b:/etc# /maven/apache-maven-3.8.5/bin/mvn -v
Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)
Maven home: /maven/apache-maven-3.8.5
Java version: 11.0.14.1, vendor: Eclipse Adoptium, runtime: /opt/java/openjdk
Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-1160.62.1.el7.x86_64", arch: "amd64", family: "unix"

创建软连接（不需要进入到原来的路径也可以验证Maven安装）

root@38d0cecdc58b:/etc# ln -s /maven/apache-maven-3.8.5/bin/mvn /usr/local/bin/

重新验证Maven安装

root@38d0cecdc58b:/etc# mvn  -v
