Running nginx in a container as reverse proxy with dynamic configuration

Question

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.

1. How will I update my site configurations in nginx to all containers (add / remove location)?
2. Is attaching a disk is the best option to store logs?
3. 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.
