构建镜像
- 1、创建文本文件并命名为Dockerfile
-
2、编写内容（以nginx为例）
FROM nginx RUN echo '<h1>hello world</h1>' > /usr/share/nginx/html/index.html -
3、编译
docker build -t nginx:v1 . -
4、查看制作好的镜像
docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx v1 bc19667caea3 6 seconds ago 109MB nginx latest c82521676580 4 weeks ago 109MB -
5、运行制作好的镜像
docker run --name web2 -d -p 81:80 nginx:v1 - 6、Dockerfile指令
#FROM：指定基础镜像 #RUN：执行命令（shell格式、exec格式） #COPY：复制文件 #ADD：更高级的复制文件 #CMD：容器启动命令 #ENTRYPOINT：入口点 #ENV：设置环境变量 #ARG：构建参数 #VOLUME：定义匿名卷 #EXPOSE：声明端口 #WORKDIR：指定工作目录 #USER：指定当前用户 #HEALTHCHECK 健康检查
