I'm trying to setup nginx as a reverse proxy in a container for my containers (Docker Swarm) and static sites which are being hosted on Google Cloud Platform & Netlify
I'm actually able to run nginx in containers, but I'm really worried about the configurations.
How will I update my site configurations in nginx to all containers (add / remove location)?
Is attaching a disk is the best option to store logs?
Is there any fault in my architecture?

Hej Sanjay.
Have a look at:
https://github.com/jwilder/nginx-proxy
https://traefik.io/
The first one is a modified Nginx Reverse Proxy by J.Wilder.
The Second one is a new and native Reverse Proxy created specially for such use cases.
Both are able to listen to the docker.socks and dnynamicly add new containers to the reverse-proxy backend.
Regarding your Architecture:
Why not running the Reverse-Proxy Containers inside the Swarm Cluster?
Related to logging, have a Look at the Docker Log-Drivers.
You can collect the Logs of all Containers with eg. fluentd or splunk.

I am trying to build a container containing 3 applications, for example:
Grafana;
Node-RED;
NGINX.
So I will just need to expose one por, for example:
NGINX reverse proxy on port 3001/grafana redirects to grafana on port 3000 and;
NGINX reverse proxy on port 3001/nodered redirects to nodered on port 1880.
Does it make any sense in your vision? Or this architecture is not feasible if compared to docker compose?
If I understand correctly, your concern is about opening only one port publicly.
For this, you would be better off building 3 separate containers, each with their own service, and all in the same docker network. You could plug your services like you described within the virtual network instead of within the same container.
Why ? Because containers are specifically designed to hold the environment for a single application, in order to provide isolation and reduce compatibility issues, with all the network configuration done at a higher level, outside of the containers.
Having all your services inside the same container thwart these mentioned advantages of containerized applications. It's almost like you're not even using containers.
I have a django app. In front of that I want to setup 3 nginx proxies (docker containers) in local (MacOS) like:
browser-->proxy1-->proxy2-->proxy3-->(gunicorn):django-app
I have to check some IP related thing in my django app. So when I am logging the x_forwarded_for header in my django app I am getting it as: 'X-Forwarded-For': '172.17.0.1, 172.17.0.1, 172.17.0.1'
I want to give each of my nginx proxy container a different static IP. How to do that. What docker command I need to use ?
I want to be able to use traefik so that I can reverse proxy both container and non-container services. And I’d like to be able to use a docker-compose file so it is easily setup and torn down. I thought this would be a common request, but I can’t find a unified example. And since I’m still really new to docker, this is a little outside of my wheelhouse. Ideally the docker-compose file would:
install the traefik container, including authentication so that traefik can be managed with a WebUI
Have traefik use Let’s encrypt to generate and maintain SSL certificates that traefik will use to reverse proxy both docker and non-docker services
install a sample container (like Apache) that will be tagged so traefik will reverse proxy to https://apache.example.com (http automatically redirects)
reverse-proxy a non-container service at http://192.168.1.15:8085 to https://foobar.example.com (http automatically redirects)
I’ve seen plenty of examples on how to use traefik and to tag new containers so that they are reversed proxied, but precious few on how to reverse proxy non-docker services. I’m sure I’m not the only one who would appreciate an example that does both at the same time.
The Docker EE docs state you can use their built in load balancer to do path based routing:
https://docs.docker.com/ee/ucp/interlock/usage/context/
I would love to use this for our local devs to have a local container cluster to develop against since a lot of our apps are using host paths to route each service.
My original solution was to add another container to the compose service that would just be an nginx proxy doing path based routing, but then I stumbled on that Docker EE functionality.
Is there anything similar to that functionality without using Docker EE or should I stick with just using an nginx reverse proxy container?
EDIT: I should clarify, in our release environments, I use an ALB with AWS. This is for local dev workstations.
The Docker EE functionality is just them wrapping automation around an interlock container, which itself runs nginx I think. I recommend you just use nginx locally in your compose file, or better yet, use traefik, which is purpose-built for this exact purpose.
Trying to setup Apache NiFi docker container, with traefik as load balancer over docker swarm network, We are able to access web UI, while browsing through UI, it redirects to docker internal host instead of proxy host name, As per below thread from Nifi here looks we need to pass http headers from proxy, couldn't find a way to set it through Traefik, any help here is much appreciated.
On a side note tested Nifi with another reverse proxy, it works fine without any extra configurations needed.
Adding below label in docker-compose for the service resolved the issue.
traefik.frontend.headers.customRequestHeaders=X-ProxyScheme:https||X-ProxyHost:<Virtual HostName>||X-ProxyPort:<Virtual Port>
