Nginx is a web server. Check the following link for the official web site.
NGINX | High Performance Load Balancer, Web Server, & Reverse Proxy
The only all‑in‑one load balancer, web server, content cache and API gateway At NGINX we're guided in all our actions…
Mainly we can use this Nginx usefully as following ways.
- Reverse proxy
- Load balancer
- Main proxy
- HTTP cache
In this article I will be explaining how I used Nginx to deploy my Rails application.
If you are not using Docker, you can install Nginx into your machine locally, or in the server you maintain.
To install Nginx
apt-get install -y nginx
and the config files can be seen in the following directory
Anyway…. I wanted to use these in Docker way.
Assume that the Rails application is already created and dockerized.
Next thing is to create the Nginx image.
I have created a Dockerfile with a config file to build my Nginx Image
Here is the Dockerfile
Config file for the Nginx. This example is about the Reverse Proxy
And that’s all I did to build my own Nginx file with a custom config file.
docker build -t admat/nginx:0.1 .
once the image is built I pushed the docker image to my Docker-hub account
docker push admat/nginx:0.1
Then, to have it with my Rails Application I added the image into my docker-compose file.
Here is the docker-compose file.
Finally , Up each containers one by one.
docker-compose up -d dbdocker-compose up -d rails-appdocker-compose up -d nginx
