有谁看见我的剑了？2023-11-16 11:25

拉取java:8-jdk-alpine镜像作为基础镜像
复制代码
```
 docker pull java:8-jdk-alpine
```

编写Dockerfile

复制代码

 mkdir  /root/Dockerfile
 cd /root/Dockerfile

vim repositories

powershell 复制代码

http://mirrors.aliyun.com/alpine/v3.8/main/
http://mirrors.aliyun.com/alpine/v3.8/community/

vim Dockerfile

powershell 复制代码

FROM  java:8-jdk-alpine
COPY repositories /etc/apk/repositories
RUN apk update && apk add tzdata 
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime 
RUN echo "Asia/Shanghai" > /etc/timezone

构建镜像
复制代码
```
 docker build -t java:8 . 
```
运行测试
复制代码
```
 docker run --rm -it  java:8 sh
```
