In this video we will learn how to #scale #docker container using #Nginx as reverse proxy, this nginx reverse proxy would also act as a load balancer at the very same time.
For example I have used a very basic Nodejs Express application to demonstrate the same.

Please include this in the "Production ready server" playlist. As horizontal auto-scaling is also a very useful feature in the production ready server. Amazing content. Thanks.

I have been scratching my head the whole day trying to figure out why my nginx wasn't working. I wasn't using docker-compose.yml; instead, I was creating separate containers for each server instance. On top of that, I was editing the main nginx configuration file (/etc/nginx/nginx.conf) instead of changing the virtual host configuration file (/etc/nginx/conf.d/default.conf) as you did. After watching your video, I figured out two issues. First, my containers were not communicating with each other because I hadn't created a custom network for them. After doing that, everything worked fine with reverse proxy and load balancing. Second, I still don't understand what the issue was with using the same upstream to specify the servers and the location with the proxy_pass directive to send them to the servers in round-robin. Maybe it's not a good practice to update the main nginx configuration file directly, but I'm not sure. Can you provide me with some resources to read more about nginx configurations? Thanks a lot; this video was a great help! 💕💕

Hi ! great video as usual !, is that a normal behavior that you can access the api container by its port without exposing the 3000 port in its Dockerfile?

Great explanation, thank you. I was just wondering, if we are running in same machine we can use cluster module as well right? The nginx with auto-scaling may become prominent when using multiple standalone servers, isn't that right?

@Xaero324 Жыл бұрын

Since there's no upstream definition in the nginx conf, we're pretty much stuck to a round-robin type of configuration with this setup right?

Great! Tank you ❤ Hey Bro, I'm scaling a Chatbot where the user's history is preserved. After scaling up I want the users second or forthcoming request to point to the First request Host. I can send the hostname to user and send it back as you shown. Can U guide how to map request to particular host?

Nice video but scaling horizontally means using different computers, and not a single one. Am I missing something here? Do you need to use Kubernetes to scale it horizontally across multiple computers?

Sir lets say i have three vps each of dual core processor and each vps will have two docker container running(of same image). How can we load balance and proxy using docker. Since the vps are different they will have different ip and container id how do we link all of them? Do we need to have another vps only for nginx to load balance or just puting nginx in vps1 it will do the job?

You're not using nginx here to load balance. You're using docker to load balancer. Tge nginx container is just a proxy in this setup.
