On version 2.7.0 the REDIS section in the configuration file changed.

Old Redis configuration:

REDIS = {
    'HOST': 'localhost',
    'PORT': 6379,
    'PASSWORD': '',
    'DATABASE': 0,
    'CACHE_DATABASE': 1,
    'DEFAULT_TIMEOUT': 300,
    'SSL': False,
}

New Redis configuration:

REDIS = {
    'webhooks': {
        'HOST': 'redis.example.com',
        'PORT': 1234,
        'PASSWORD': 'foobar',
        'DATABASE': 0,
        'DEFAULT_TIMEOUT': 300,
        'SSL': False,
    },
    'caching': {
        'HOST': 'localhost',
        'PORT': 6379,
        'PASSWORD': '',
        'DATABASE': 1,
        'DEFAULT_TIMEOUT': 300,
        'SSL': False,
    }
}

So, before the build this need to be changed in the file:

/configuration/configuration.py

On version 2.7.0 the REDIS section in the configuration file changed.

I don't think that this is the problem here. The error would be "REDIS section in configuration.py is missing webhooks subsection.", but I don't see that in the logs.

Can you add the output of docker inspect netboxcommunity/netbox:latest here (or in a gist and a link here), so that we know exactly which Docker Image is running on your machine?

Also, you're local repository seems to be on a weird commit (4e25b8a). Please update either to the release branch or to a specific release:

# 1: Update to a specific release of Netbox Docker
# (I've chosen 0.19.3 here, because you've opened the bug report before we released 0.20.0)
git fetch -p
git checkout 0.19.3

# 2: Get latest v2.6 image
docker pull netboxcommunity/netbox:v2.6
VERSION=v2.6 docker-compose up
