I have been stuck for so long trying to configure the server blocks for my docker droplet. For a beginner like me who until today hadn't even heard of a server block, this was so much more informative than the digital ocean documentation on setting up nginx!!
Thank you so much for this. I have struggled with this, and with some tweaks to the firewall and certbot, it's finally working! Thank you again for the straightforward and uncomplicated directions.
How to access container without changing end point url... for example I have an web api. I will run my web api as 2 container like instance..I want to access.
Nice tutorial! Thank you! I was wondering if it's possible to do the same, but with php-fpm containers. Which would be the right configuration for nginx in this case?
You can do that with a free Let's Encrypt SSL and certbot: www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04
what about if i use nginx server as a container. mean my app deploy on one container and i have second container called nginx how i configure my nginx container as a reverse proxy? hope you understand my question. kindly reply
Nice video that help me so much. But it seen the reverse proxy i configure doesn't work. It doesn't work unless i type the port of my app. My context is : I dockerize a laravel app with 3 services(app, db , webserver(which is nginx)) and it host on hostinger vps.

Hi there, I setup A records for each subdomain name to point to the Droplet's IP address before the video. Here is how you could do that: www.digitalocean.com/docs/networking/dns/how-to/manage-records/
Thank you so much for the video. I have my intel NUC setup and i have domain name as well, do we need to also do port forwarding in router or Nginx will take care of it ?
In case that you are just getting started with Docker, I could suggest this free eBook here too: devdojo.com/bobbyiliev/free-introduction-to-docker-ebook
Hey! For the example I created the DNS records in my DNS zone beforehand, but you could use your hosts file on your local machine if it is just for testing too
does this works even if I'm using like 3 docker containers to run a single app with wordpress? I want to use nginx as a load balancer between the containers to run wordpress.
Yep, this should work with 3 WordPress containers as well. You might have to add some extra proxy rules in the Nginx Server Blocks to make it work for WordPress
i tried to follow this on a Centos vm, when i browse to docker1 url, it keeps taking me to welcome centos url page for somereason, i keep having to add the port number still even though i installed nginx
Hi, it sounds like that the Nginx server block configuration that you have is not correct. Feel free to post a question on the DigitalOcean community forum and include your current configuration files: www.digitalocean.com/community/questions
Hello, In this case I could suggest following the steps here on how to build a Node.js application with Docker: www.digitalocean.com/community/tutorials/how-to-build-a-node-js-application-with-docker
Hi, I ran into an issue while implementing this great solution. Let's say I run the Nginx server as a docker container and it remains up. Now I have a microservices container(dockerized), and is accessed via Nginx reverse proxy. In case when a microservice's container is down for sometime and then restarted, the Nginx throws an upstream error. The upstream error occurs even if the container is up and running. Would appreciate any solution for this issue
Hi there! This sounds like an interesting setup! Indeed running the Nginx service in a Docker container sounds like a better approach in some cases. In your Nginx configuration, are you using the Docker container IPs for the `server_block`? It sounds like that the docker container IP changes and then the Nginx service is no longer able to connect to the upstream. If this is the case I could suggest 2 things: - Make sure to create a docker network and use the container names rather than the container IPs: www.digitalocean.com/community/questions/how-to-ping-docker-container-from-another-container-by-name - Make sure to specify a restart policy so that if a service crashes, it would be restarted again: www.digitalocean.com/community/questions/how-to-start-docker-containers-automatically-after-a-reboot Finally if none of this helps, I would recommend checking your container logs for some more information on what is wrong: docker logs container_id_here Hope that this helps!
@@bobbyiliev_ Thanks for your response. I am referring to the containers through their container names. Digging deeper into this issue, looks like an issue not from Nginx. What I observed: I have two containers, one built on Phoenix-elixir, the other built on Flask-uWSGI. This upstream error doesnt occur when I tried stopping and restarting the phoenix container. The issue was specific to the flask container. This certainly seems to be an issue somewhere inside uWSGI. Will get back if i found a solution for this :)
Hi there, The approach is more or less the same, however of course there are some differences between the different Linux distros. For example to install Nginx on CetnOS you would use dnf or yum and not apt.

Why do you need apache? So isn't nginx enough to do that? Apache + nginx might be sacrificing nginx efficiency... Sounds like running linux on a windows machine.
The Apache containers were used only for the demo. You of course have to change them with your own application like NodeJS or whatever you are running Inside the container.

It's an httpd appache revers server not an Nginx one.
Not really, it is an Nginx Reverse proxy, in this case the Apache httpd was just the backend service, but it could be anything
