## Java 环境

270+
基于 `openjdk:11` 创建一个包含 `Maven` 的自定义 Docker 镜像
271+
272+
```dockerfile
273+
FROM --platform=linux/amd64 openjdk:11
274+
275+
# 安装 Maven 3.8.7
276+
ENV MAVEN_VERSION=3.8.7

278+
&& wget https://archive.apache.org/dist/maven/maven-3/${MAVEN_VERSION}/binaries/apache-maven-${MAVEN_VERSION}-bin.tar.gz \
279+
&& tar xzf apache-maven-${MAVEN_VERSION}-bin.tar.gz -C /opt \
280+
&& ln -s /opt/apache-maven-${MAVEN_VERSION} /opt/maven \
281+
&& rm apache-maven-${MAVEN_VERSION}-bin.tar.gz
282+
283+
# 设置 Maven 环境变量
284+
ENV MAVEN_HOME=/opt/maven
285+
ENV PATH="${MAVEN_HOME}/bin:${PATH}"
286+
287+
# 创建非 root 用户并设置权限
288+
RUN useradd -u 1000 -ms /bin/bash jenkins \
289+
&& mkdir -p /home/jenkins/.m2/repository \
290+
&& chown -R jenkins:jenkins /home/jenkins/.m2
291+
292+
# 切换到非 root 用户
293+
USER jenkins
294+
295+
# 验证 Maven 版本
296+
RUN mvn -version
297+
```
298+
299+
构建 `openjdk` 新的镜像，命名为 `my-openjdk-maven`
300+
301+
```sh
302+
docker build -t my-openjdk-maven:3.8.7 .
303+
# 保存 Docker 镜像到本地文件
304+
docker save -o my-openjdk-maven.3.8.7.tar my-openjdk-maven:3.8.7
305+
docker save -o my-openjdk-maven.3.8.8.tar my-openjdk-maven:3.8.8
306+
# 上传到服务器
307+
scp -P 2222 my-openjdk-maven.3.8.7.tar root@106.55.8.163:/home/docker-images
308+
```
309+
310+
加载 docker 自定义镜像
311+
312+
```sh
313+
docker load -i ./my-openjdk-maven.3.8.7.tar
314+
```
315+
316+
这事缓存下载的 maven 的包
317+
318+
```sh
319+
docker run -it --rm my-openjdk-maven:3.8.7 /bin/bash
320+
# 在【容器】内运行
321+
id jenkins
322+
# uid=1000(jenkins) gid=1000(jenkins) groups=1000(jenkins)
323+
# 在【宿主机】上使用这些 ID 来更改目录的拥有者
324+
sudo chown -R 1000:1000 /root/.m2/
325+
# 将目录权限设置为可读写
326+
sudo chmod -R 777 /root/.m2/
