how can i route from one nginx serve to another?
i have a containerized nginx server currently setup with https (nginx.main) and it's serving my django app that's in another container. unfortunately, django is not responding with the static files - and i've read that's a normal thing. so, what i'd like to do is setup another instance of nginx to do that for me (nginx.static) nginx.main default.conf config that i've tried: ...some stuff going to --> server { listen 4430 ssl; listen [::]:4430 ssl default ipv6only=on; server_name avnav.com; ssl_certificate /etc/nginx/_cert/etc/letsencrypt/live/avnav.com/fullchain.pem; ssl_certificate_key /etc/nginx/_cert/etc/letsencrypt/live/avnav.com/privkey.pem; ssl_dhparam /etc/nginx/_cert/etc/letsencrypt/live/dhparam.pem; ...some security stuff... location / { proxy_pass http://django_app; proxy_set_header Host avnav.com; } location /media { proxy_pass http://nginx_static; } } nginx.main nginx.conf config: upstream django_app { server droplet.ip:8000; } upstream nginx_static { server droplet.ip:8082; } nginx.static default.conf config: server { listen 8080 default; server_name localhost; location / { root /usr/share/nginx/static/; } at first i thought it was an issue with alias vs root, but not so. the volumes are setup so that the host static files are mounted to /usr/share/nginx/static in nginx.static. inside that folder, there are subfolders for css, js, etc. nginx.main runs on port 8081:8080 django runs on 8000 nginx.static runs on 8082:8080 -

How to connect AWS Elasticache Redis from a local machine for a Django project?
I've Redis chace installed on both my local and aws elasticache. My Django project runs well on my local machine with Redis. However, when I connect to my redis remotely on aws, I get the following error. Error 10060 connecting to xyz.0001.use2.cache.amazonaws.com:6379. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. I have the following Django settings for the local redis: CACHES = { 'default': { 'BACKEND': 'django_redis.cache.RedisCache', 'LOCATION': 'redis://127.0.0.1:6379/1', 'OPTIONS': { 'CLIENT_CLASS': 'django_redis.client.DefaultClient', } } } And this the Django settings for the remote redis instance: CACHES = { 'default': { 'BACKEND': 'django_redis.cache.RedisCache', 'LOCATION': 'redis://xyz.0001.use2.cache.amazonaws.com:6379', 'OPTIONS': { 'CLIENT_CLASS': 'django_redis.client.DefaultClient', } } } Again, when I switch from local to remote caches settings, I get that error above. I know that I it is not possible to connect ElastiCache outside AWS unless you have a vpn connection. So, I've set up the vpn client end point on aws and connected to it using the aws vpn client. I can successfully connect via vpn as shown below. Any idea why I still can't connect from my local machine to the remote redis … -

Handle requests that demand high RAM in Django
I have developed a geospatial app using Django. Users have the potential to draw a polygon and to get data analysis for the pixels included in the polygon. In order to get this data analysis, each request demands several GB and a couple of minutes to show the result. What if many users make a response at the same time? There will be a problem regarding the RAM. What I need is to put the requests into a queue, inform the user with a message about the waiting and execute one by one the requests.
