安装
常用操作
1. 容器管理
查看运行容器
docker ps
查看所有容器
docker ps -a
停止运行容器
docker stop [容器名称或id]
运行容器
docker start [容器名称或id]
进入容器
docker exec -it [容器名称或id] /bin/bash
运行容器 随机分配端口（大写p）
docker run -d -P --name [容器名称] [镜像名]:[tag]
指定端口（小写p）80内部容器端口
docker run -d -p [本机端口]:[容器端口] --name [容器名称] [镜像名]:[tag]
删除已有容器
docker rm [容器id]
删除所有未运行容器
docker rm docker ps -a -q
查看容器日志
docker logs [容器id]
拷贝文件到容器
docker cp [源文件] [容器名称或id]:[目标路径]</pre>
2. 镜像管理
查看本地镜像
docker images
删除image镜像
docker rmi [镜像id多个空格隔开]
删除所有镜像
docker rmi docker images -a -q
导出导入容器
docker export [容器id] > [压缩包]
cat [压缩包] | docker import [压缩包] [镜像名]:[tag]
docker import http://example.com/exampleimage.tgz [镜像名]:[tag]
将现有容器创建成镜像
docker commit -a ["作者"] -m ["描述"] [容器名称或id] [镜像名]:[tag]</pre>
3. DockerFile制作

#del install files
RUN rm -rf /usr/local/src/*

EXPOSE 80 81 443
ADD entrypoint.sh /usr/local/src
RUN chmod -R 777 /usr/local/src/entrypoint.sh
ENTRYPOINT ["/usr/local/src/entrypoint.sh"]</pre>
- 镜像打包
docker build -t [镜像名]:[tag] .
4. 仓库管理
登入
docker login
登出
docker logout
镜像搜索拉取
docker search [镜像名称]
docker pull [镜像名称]
推送镜像
docker push [镜像名称]:[tag]</pre>
5. docker-compose制作
参考地址：https://www.runoob.com/docker/docker-compose.html
version: "3"
service01:
image: [镜像名称]:[tag]
container_name: [容器名称]
ports:
- "[本机端口]:[容器端口]"
- .....
volumes:
- [源文件地址]:[容器地址]
- .....
links:
- [service02]
- ...
network_mode: "host"
restart: always
service02:
6. docker备份迁移
容器保存为镜像
docker commit mynginx mynginx_i
镜像备份
docker save -o mynginx.tar mynginx_i
镜像恢复与迁移
docker load -i mynginx.tar
