docker - 如何使用官方 docker-compose 文件安装 Airflow 的附加要求

Question

我正在使用下面的 docker-compose.yml。对于我的一些狗，我需要安装额外的要求。是否可以在使用官方 docker compose 文件时指定要安装的其他 python 包？

Answer 1

扩展官方镜像非常简单。这是我所做的:

在 docker-compose.yml 中替换

  image: ...

通过

  build: ./airflow

然后，创建一个 airflow 文件夹，然后在其中创建一个 Dockerfile。这是我用来避免不必要警告的内容。

FROM apache/airflow:2.0.1
# this fixes a warning in the official image, with the Azure provider
# More info here https://github.com/apache/airflow/issues/14266#issuecomment-786298240
RUN pip uninstall  --yes azure-storage && pip install -U azure-storage-blob apache-airflow-providers-microsoft-azure==1.1.0
# add your dependencies here:
# RUN pip install package1 package2....

然后只需将 --build 开关添加到您的 docker-compose 命令

docker-compose up --build airflow-init
docker-compose up -d

尽情享受吧!
