docker-compost with postgres与地理postgis不起作用

我正在使用运行flask应用程序的docker-compose容器。在该容器中,将启动具有Postgis扩展名的Postgres容器(mdillon/postgis图像)。一切运行正常,但单个Postgis扩展名(地理)无法正常工作,我无法解释。

我的docker-compose.yml:

version: '3.7'
services:
  flask:
    build: .
    entrypoint:
      - flask
      - run
      - --host=0.0.0.0
    environment:
      FLASK_DEBUG: 1
      FLASK_APP: app.py
    ports:
      - '5000:5000'
    volumes:
      - './app:/app'
    networks:
      - db_net
  db:
    image: mdillon/postgis
    networks:
      - db_net

networks:
  db_net:

运行sudo docker-compose up --build后,它将创建两个容器:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                     NAMES
1836d3d15765        img_flask         "flask run --host=0.…"   9 minutes ago       Up 9 minutes        80/tcp, 443/tcp, 0.0.0.0:5000->5000/tcp   img_flask_1
b25752af45ad        mdillon/postgis     "docker-entrypoint.s…"   13 minutes ago      Up 13 minutes       5432/tcp                                  img_db_1

打开flask应用程序或数据库日志时,它声明以下内容:

sqlalchemy.exc.ProgrammingError: (psycopg2.errors.UndefinedObject) type "geography" does not exist
LINE 7:  geom geography(POINT,4326)

检查postgis正确,并且在数据库中重新安装它不能解决问题。软件包如下:

                                            List of installed extensions
          Name          | Version |   Schema   |                             Description                             
------------------------+---------+------------+---------------------------------------------------------------------
 fuzzystrmatch          | 1.1     | public     | determine similarities and distance between strings
 plpgsql                | 1.0     | pg_catalog | PL/pgSQL procedural language
 postgis                | 2.5.0   | public     | PostGIS geometry, geography, and raster spatial types and functions
 postgis_tiger_geocoder | 2.5.0   | tiger      | PostGIS tiger geocoder and reverse geocoder
 postgis_topology       | 2.5.0   | topology   | PostGIS topology spatial types and functions
(5 rows)

总而言之,我的容器可以正常工作,并且Postgis安装得很好。但是当查询请求地理功能时会出现问题。是否有人可以提供有关如何解决此问题的建议?谢谢!

已修复,偶然在其他数据库中工作。 @杰里米,谢谢!
