+### 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
+```
