## README

# Docker 使用


## 生成依赖包列表
```shell
pip freeze > requirements.txt
```

## 制作Dockerfile
```dockerfile
# 基于的环境
FROM python:3.8

#代码添加到code文件夹
ADD . /code

# 设置code文件夹是工作目录
WORKDIR /code

# 安装支持
RUN pip install -r requirements.txt
CMD ["python", "./src/main.py"]
```

## 制作Docker镜像
```shell
docker build -t image-docker .
```

## 打包Docker镜像
```shell
docker save -o out-image-docker.tar image-docker
```

## 打包容器
```shell
docker export dfc4d1182bac530ff0858c286c1b8f4161d8ce1e111ef02a82c3fb62007e1696 > container_middle-layer-manager.tar
```

## 解压Docker镜像
```shell
docker load < image_pack_middle-layer-manager.tar
```

## 镜像生成容器
```shell
docker run -itd --name container_middle-layer-manager image_middle-layer-manager
# 对外映射容器内8000端口到服务器端口80
docker run -it -d --name container_middle-layer-manager -p 80:8000 image_middle-layer-manager
```

## 运行Docker镜像(生成任意命名容器)
```shell
docker run -it image-docker
```

## 进入容器
```shell
docker exec -itd 702be9fac2d9bcdbb9f0159f8378e4fab92f09d2481c0c30904ad22b751daa97 /bin/sh
```

## 查看所有镜像
```shell
docker images
```

## 显示所有容器
```shell
docker ps -a
```

## 复制文件到Docker容器中
```shell
docker cp gui.py b6d0f85219ea:/usr/local/lib/python3.8/site-packages/remi
docker cp gui.py container_middle-layer-manager:/usr/local/lib/python3.8/site-packages/remi
```
