1、什么是Docker
docker是一门容器技术，其作用是解决软件跨环境迁移的问题
2、三大概念
仓库:一个总的仓库，包含所有的镜像，使用时可以从库拉取镜像到本地。 镜像:从库中拉取下来的应用，比如mysql 容器:镜像运行之后就是容器，容器和镜像可以互相转换 3、Docker安装
yum update yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo yum install -y docker-ce docker -v 4、常用指令
docker pull xx:5.6 docker run xx docker stop xx docker images docker ps docker run --name smartpark -p 8081:8081 -d smartpark # --name 别名 --env 环境变量 -d 后台执行 --link ip映射 -p 端口映射 docker run --name mywordpress --link db:mysql -p 8080:80 -d wordpress docker logs -f smartpark docker rm 27dfa1fc17bc docker port CONTAINER_ID docker top name 5、Dockerfile
Dockerfile 是一个用来构建镜像的文本文件，文本内容包含了一条条构建镜像所需的指令和说明。
//Dockerfile文件 FROM java:8 MAINTAINER itfeng<xxxxxx666@163.com> ADD ./group5-0.0.1-SNAPSHOT.jar app.jar CMD java -jar app.jar Dockerfile构建镜像
docker build -f ./Dockerfile -t app . 创建容器
docker run -id -p 7777:7777 app 6、compose
一个方便维护多个容器的yaml文件，docker认为一个容器对应一个进程，但一个应用会有多个进程，例如上面的mysql和wordpress。类似于shell脚本，访问的是docker的一些api。
docker-compose logs docker exec -it name /bin/sh 编写 docker-compose.yml 文件
