[英]How to install additional requirements for Airflow using official docker-compose file
我正在使用下面的 docker-compose.yml。 對於我的一些 dags,我需要安裝額外的要求。 在使用官方 docker 撰寫文件時,是否可以指定要安裝的其他 python 包?

擴展官方形象很容易。 這是我所做的:
在docker-compose.yml
替換
image: ...
經過
build: ./airflow
然后,創建一個airflow
文件夾,然后在其中創建一個Dockerfile
。 這是我用來避免不必要警告的方法。
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....
然后只需將--build
開關添加到您的 docker-compose 命令
docker-compose up --build airflow-init
docker-compose up -d
