Unable to make a "Get" call to a django app residing in a docker container from a flask app in another docker container

Question

I am referring to the tutorial, https://www.youtube.com/watch?v=0iB5IPoTDts. At from 1:18:09 in the tutorial, I am supposed to implement this code below

[Api call from a flask app in a docker container to a django app residing in another docker container][1]

But I keep getting maximum retry error. [Error image][2]

It seems like the get request is failing. I referred to the following link How to get the IP address of the docker host from inside a docker container, and tried solutions present in answer 1 and 2, but they give an error 400.

I am quite novice in flask and django. Please help. Thanks in advance. [1]: https://i.stack.imgur.com/O0tZf.png [2]: https://i.stack.imgur.com/UozYE.png

Answer 1

Adding the host to "allowed hosts" in settings.py resolved the error.

Reference: Invalid http_host header
