Docker编写气流2(版本2.0.0)的文件 [英] Docker compose file for airflow 2 ( version 2.0.0 )

问题描述

我希望编写docker compose文件，以在类似环境的生产环境中本地执行气流.

I am looking to write docker compose file to locally execute airflow in production similar environent.

对于较老的气流v1.10.14，泊坞窗compose运行良好.但是，相同的docker compose不适用于最新的稳定版本，airflow Scheduler&Web服务连续失败.错误消息看起来像无法创建审核表.

For older airflow v1.10.14, docker compose is working fine. But same docker compose is not working for latest stable version, airflow scheduler & webservice is failing continuously. error message looks like unable to create audit tables.

docker-compose.yaml :

 version: "2.1"
services:
  postgres:
    image: postgres:12
    environment:
      - POSTGRES_USER=airflow
      - POSTGRES_PASSWORD=airflow
      - POSTGRES_DB=airflow
    ports:
      - "5433:5432"

  scheduler:
    image: apache/airflow:1.10.14
    restart: always
    depends_on:
      - postgres
      - webserver
    env_file:
      - .env
    ports:
      - "8793:8793"
    volumes:
      - ./dags:/opt/airflow/dags
      - ./airflow-logs:/opt/airflow/logs
      - ./plugins:/opt/airflow/plugins
    command: scheduler
    healthcheck:
      test: ["CMD-SHELL", "[ -f /usr/local/airflow/airflow-webserver.pid ]"]
      interval: 30s
      timeout: 30s
      retries: 5

  webserver:
    image: apache/airflow:1.10.14
    hostname: webserver
    restart: always
    depends_on:
      - postgres
    env_file:

      interval: 30s
      timeout: 30s
      retries: 5
