### 一、下载$JDK21$

> https://download.oracle.com/java/21/latest/jdk-21_linux-x64_bin.tar.gz



### 二、利用阿里云的$ECS$制作私有镜像

```shell
在阿里云购买了一台ECS主机

8.147.134.252
用户名： root
密  码：DsideaL4r5t6y7u!@#
```



### 三、安装$Docker$

```shell
yum install -y yum-utils
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y

# 配置Docker加速器
sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://95lqrpjl.mirror.aliyuncs.com"]
}
EOF

systemctl daemon-reload
systemctl restart docker
```



### 四、生成$JDK$基础镜像

```shell
yum install lrzsz -y
rz -be 
选择：D:\SetupSoftware\JDK21\jdk-21_linux-x64_bin.tar.gz

```



```dockerfile
cat Dockerfile 


# 使用 Debian 11 slim 作为基础镜像
FROM debian:11-slim

# 设置环境变量
ENV jdk=jdk-21_linux-x64_bin.tar.gz
MAINTAINER bright "10402852@qq.com"

# 配置镜像源
RUN sed -i 's/deb.debian.org/mirrors.aliyun.com/g' /etc/apt/sources.list

# 更新软件包索引并安装必要的工具和依赖
RUN apt-get update && apt-get install -y \
    locales \
    tzdata \
    && rm -rf /var/lib/apt/lists/*

# 如果您需要某个特定的 locale，例如 en_US.UTF-8，则生成它
RUN locale-gen en_US.UTF-8


# 安装设置时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo "Asia/Shanghai" > /etc/timezone

# 添加 JDK 文件


COPY $jdk /usr/local/
RUN tar -zxvf /usr/local/$jdk -C /usr/local/ && rm /usr/local/$jdk

# 设置环境变量
ENV JAVA_HOME=/usr/local/jdk-21.0.1
ENV PATH=$JAVA_HOME/bin:$PATH
```



```shell
docker build -t dsideal/jdk:21 .
```



### 五、查看$JDK$信息

```shell
#测试镜像
docker run --rm -it --name test dsideal/jdk:21
#进入临时镜像测试是否成功
java -version
```



### 六、上传到黄海的个人私有仓库

```shell
# 登录黄海的个人镜像仓库
docker login --username=东师黄海 registry.cn-hangzhou.aliyuncs.com --password DsideaL4r5t6y7u
 
# 修改tag标签 
docker tag dsideal/jdk:21 registry.cn-hangzhou.aliyuncs.com/dsideal/jdk:21

# 上传镜像
docker push registry.cn-hangzhou.aliyuncs.com/dsideal/jdk:21

# 测试拉取
docker pull registry.cn-hangzhou.aliyuncs.com/dsideal/jdk:21
```
