Where's the right place to enable ALLOW_ALL_HOSTS?

[steeeeev0]

I'm using docker (with GPU) and can't seem to find the right spot to enable ALLOW_ALL_HOSTS

When I clone the repo and start the containers using docker-compose -f docker-compose.gpu.yml -f docker-compose.prod.yml -f docker-compose.prod.selfhost.yml up the following error appears in the docker logs when attempting to visit http://10.0.80.10:80 (IP address of the docker host running Spleeter-web):

api_1          | django.core.exceptions.DisallowedHost: Invalid HTTP_HOST header: '10.0.80.10'. You may need to add '10.0.80.10' to ALLOWED_HOSTS.

The browser on my laptop shows: Bad Request (400)

Makes sense. However, when I add =1 to - ALLOW_ALL_HOSTS under the api service in docker-compose.gpu.yaml, the container won't start:

ERROR: for spleeter-web_api_1  'ContainerConfig'

ERROR: for api  'ContainerConfig'

Removing =1 and starting the containers again gets the app to start, but I still cannot access it from a remote host.

Where's the right spot to enable ALLOW_ALL_HOSTS?

Thanks!

I have also used $ export ALLOW_ALL_HOSTS=1 before starting the docker containers, and the same api service start error keeps the containers from starting. Using $ export ALLOW_ALL_HOSTS=0 also caused the startup error, I had to use unset ALLOW_ALL_HOSTS for the app to come back up.

I also tried $ export ALLOWED_HOSTS=10.0.80.10 and $ export ALLOWED_HOSTS=0.0.0.0 and $ export ALLOWED_HOSTS=[*] the app started, but I still got the 400 error in the browser.

$ env | grep ALLOWED_HOSTS
ALLOWED_HOSTS=0.0.0.0

[steeeeev0]

I have also tried editing both settings.py and settings_docker.py in django_react/:

ALLOW_ALL_HOSTS = '1'
ALLOWED_HOSTS = ['*']

#ALLOW_ALL_HOSTS = os.getenv('ALLOW_ALL_HOSTS', '0') == '1'
#if ALLOW_ALL_HOSTS:
#    ALLOWED_HOSTS = ['*']
#else:
#    ALLOWED_HOSTS_SET = {'0.0.0.0', '127.0.0.1', 'localhost'}
#    if os.getenv('APP_HOST'):
#        ALLOWED_HOSTS_SET = ALLOWED_HOSTS_SET.union(set(os.getenv('APP_HOST').split(',')))
#    ALLOWED_HOSTS = list(ALLOWED_HOSTS_SET)

Still cannot load the frontend, 400

Here is more context for the error about headers:

I was able to build manually and can access everything through the browser.

The only environment variable I set was ALLOWED_HOSTS=[*] and retained the edits I made to the settings*.py files.

I'm curious why $ export ALLOW_ALL_HOSTS=1 caused the KeyError: 'ContainerConfig' issue at startup?

[steeeeev0]

Since I've got this up and running, I am having the "Error writing file" issue. I posted in the existing issue.

To answer your original question, if you revert any edits, you should be able to either export ALLOW_ALL_HOSTS=1 or add ALLOW_ALL_HOSTS=1 to an .env file at the root of the checked out repo.

Alternatively, you can export APP_HOST=10.0.80.10 or add APP_HOST=10.0.80.10 to .env.

ALLOWED_HOSTS is used by Django only and isn't configurable directly, which I understand can be confusing.

Regarding the ContainerConfig error, can you try running docker compose (v2) instead of docker-compose (v1)? I should update the README.md to reflect this.
