如何从flask应用程序的docker容器连接到本地mongodb

Question

I have a flask application which is running as docker container. Flask application uses local mongodb. This docker container is not able to connect to local mongodb.

I have tried following option :

• set --network="host" in docker run ... command

• set MONGO_URI = "mongodb://host-ip-address:27017/model-service-sample" ,

• set MONGO_URI = "mongodb://container-gateway-ip-address:27017/model-service-sample"

None of the above options worked.

Can anyone please suggest a way to accomplish this?

For MacOS you should use:

host.docker.internal or gateway.docker.internal

for connecting from a container to a service on the host.
