Hello,
I am using the Django rest framework to provide REST API to other
services.
All services have been packaged in docker. and all services are sharing
data via the docker network.
Let's say, App A is calling App B(Django) APIs.
because they are on the same docker network then App A can call it like
HTTP://server_B_container_name:8000/api/
But I got a DisallwedHost exception. The error message likes this:
"Invalid HTTP_HOST header: 'training_api'. The domain name provided is not
valid according to RFC 1034/1035."
I have set the settings like this.
DJANGO_ALLOWED_HOSTS=localhost,training_api,*
It works if I call it through localhost on the host, or container IP
inside App A container or a fully qualified domain name of the host(port
8000 is exposed to host) from other machines.
How can I call the Django via container name from App A, not the IP? the
IP will change every time it starts.
Thanks,
Robin
