Docker Compose 备忘

1。docker-compose.yml
 

services:air-web:build: .ports:- "1027:1027"volumes:- .:/codedepends_on:- air-redisair-redis:image: "redis:alpine"
2. Dockerfile

FROM python:3.12-slim-bookworm
#设置工作目录
WORKDIR /code
#将当前目录内容拷贝到容器中的code目录
COPY . /code
#安装依赖
RUN pip install --no-cache-dir -r requirements.txt
#暴露端口
EXPOSE 1027
#运行应用
CMD ["python","app.py"]

3.requirements.txt

flask
redis
faker

4.app.py

from flask import Flask
from redis import Redis
from faker import Fakerapp = Flask(__name__)
redis = Redis(host='redis', port=6379)@app.route('/')
def home():count = redis.incr('hits')faker = Faker(locale='zh_CN')return 'Hi {},我被点击了：{}次'.format(faker.name(), count)if (__name__ == '__main__'):app.run(host="0.0.0.0", port=1027, debug=True)

5.命令：

docker compose up        初次运行，修改Dockerfile后用：

docker compose up --build -d 强制后台及重新编译

docker compose ps    查看当前状态

docker compose down   关闭当前的项目，如果修改过services name后，用

docker compose  down -p projname  强制关闭之前的项目
