如何通过撰写文件将服务器配置传递给 postgres docker？

  • 772

我正在使用 Postgres docker 14.4。我想将服务器配置（比方说idle_session_timeout）传递给 postgres docker。该文档给出了一个使用 docker run 的示例

docker run -d --name test-db -e POSTGRES_PASSWORD=postgres postgres -c idle_session_timeout=900000

如何在 docker-compose 中传递此选项？我的 docker-compose 文件现在如下所示 -

version: '3'
services:
  pgadmin:
    container_name: pgadmin
    image: dpage/pgadmin4
    ports:
      - "6555:80"       # pg admin
      - "6432:6432"     # postgres-db
    environment:
      PGADMIN_DEFAULT_EMAIL: [email protected]
      PGADMIN_DEFAULT_PASSWORD: admin

  postgres-db:
    container_name: test-db
    image: postgres:14.4
    network_mode: "service:pgadmin"
    command: -p 6432
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      PGUSER: postgres
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -p 6432"]
      interval: 5s
      timeout: 5s
      retries: 3

    它可以在command部分中传递。设置为 15 分钟的更新的 docker-compose 文件idle_session_timeout如下所示

    version: '3'
services:
  # IMPORTANT NOTE: All other services will share the network on pgadmin service (network_mode: "service:pgadmin"), so ports need to be opened here instead of other the services.
  # It is added for debugging purpose & may be removed in future when the tests using docker container looks stable
  pgadmin:
    container_name: pgadmin
    image: dpage/pgadmin4
    ports:
      - "6555:80"       # pg admin
      - "6432:6432"     # postgres-db
    environment:
      PGADMIN_DEFAULT_EMAIL: [email protected]
      PGADMIN_DEFAULT_PASSWORD: admin

  postgres-db:
    # Postgres version should be compatible with Aurora:
    # https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraPostgreSQL.Updates.20180305.html
    container_name: test-db
    image: postgres:14.4
    network_mode: "service:pgadmin"
    command: -p 6432 -c idle_session_timeout=900000
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      PGUSER: postgres
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -p 6432"]
      interval: 5s
      timeout: 5s
      retries: 3
