Http Request between two dockers and nginx
I'm tryin to build and aplication made of containers with a djanjo server, a REST API an an nginx server, but I'm not able to send a post HTTP request from django to rest api. In local everythong works fine, and in the conteinari This is my request, it always get a 400 error code: headers = {'content-type': 'application/json'} r = requests.post('http://brokkr:5000/action', params=data, headers=headers) And this is my docker-compose file: version: '3.7' services: loki: build: context: ./Loki dockerfile: Dockerfile.prod command: gunicorn server.wsgi:application --bind 0.0.0.0:8000 ports: - 8000:8000 networks: - my-network depends_on: - brokkr brokkr: build: context: ./Brokkr dockerfile: Dockerfile command: gunicorn -b 0.0.0.0:5000 api:api ports: - 5000:5000 networks: - my-network nginx: build: ./nginx ports: - 80:80 networks: - my-network depends_on: - loki - brokkr networks: my-network: driver: bridge All of the containers start with out problem and both servers(django and falcon) pront that they are both listening. I think that the problem has to do with my nginx conf: upstream server{ server loki:8000; } server { listen 80; location / { proxy_pass http://server; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } location /staticfiles/ { alias /home/server/web/staticfiles/; } } -

How did a hacker produce this GET request?
I am just about to go live with a website and am addressing security issues. The site has been public for some time but not linked to the search engines. I log all incoming requests and today noticed this one: GET /home/XXXXX/code/repositories/YYYYY-website/templates where XXXXX is a sudo user on my server and YYYYY is my company name. This is actually the structure of my Django project code. My website is coded using Django and runs under Apache2 on Ubuntu. My question is how can this guy possibly know the underlying code/directory structure on my server, in order to create this request? Their IP is : 66.249.65.221. They come up as 100% a hacker on https://ip-46.com Any contributions welcome. -

Django sphinx documentation does not read environment variables in settings file
I want to document my cookiecutter django project with sphinx. The problem is that when running make html sphinx gives me problems reading the config file. It says django.core.exceptions.ImproperlyConfigured: Set the USE_DOCKER environment variable When not calling django.setup() it also throws me an error with my envs: django.core.exceptions.ImproperlyConfigured: Set the POSTGRES_DB environment variable When I hardcode them, the error goes on to complain about the next environment variable. I can't hardcode them all into the config file, that is not an option. My environment variables are properly configured. When I print them out running my localhost they are there. It seems that somehow sphinx cannot process them. I am also using docker, so maybe that could interfere but I don't know. Here are parts of my sphinx config: sys.path.insert(0, os.path.abspath('..')) os.environ['DJANGO_SETTINGS_MODULE'] = 'config.settings.local' Here are parts of my local settings: INTERNAL_IPS = ['127.0.0.1', '10.0.2.2'] if env('USE_DOCKER') == 'yes': import socket hostname, _, ips = socket.gethostbyname_ex(socket.gethostname()) INTERNAL_IPS += [ip[:-1] + '1' for ip in ips] # django-extensions # ------------------------------------------------------------------------------ # https://django-extensions.readthedocs.io/en/latest/installation_instructions.html#configuration INSTALLED_APPS += ['django_extensions'] # noqa F405 # https://docs.djangoproject.com/en/dev/ref/settings/#databases DATABASES = { # 'default': env.db('DATABASE_URL'), # This was the default value, but modification below seemed necessary 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': … -
