Docker NGINX
Docker NGINX Tutorial – We shall learn to run NGINX in a Docker Container on Ubuntu. Following is a step by step guide to dockerize NGINX :
1. Install Docker Engine
Docker is the prerequisite.
Follow the tutorial, Install Docker on Ubuntu, to install docker on your computer with Ubuntu.
2. Pull NGINX from Docker Hub
Run the following command to pull NGINX from Docker Hub to Docker Host.
$ sudo docker pull nginx
arjun@arjun-VPCEH26EN:~$ sudo docker pull nginx [sudo] password for arjun: Using default tag: latest latest: Pulling from library/nginx afeb2bfd31c0: Pull complete 7ff5d10493db: Pull complete d2562f1ae1d0: Pull complete Digest: sha256:aa1c5b5f864508ef5ad472c45c8d3b6ba34e5c0fb34aaea24acf4b0cee33187e Status: Downloaded newer image for nginx:latest
3. Run Docker with nginx
Run the following command as root user.
$ docker run --name docker-nginx -p 80:80 -d nginx
–name docker-nginx : Name given to the container that is run is docker-nginx-p 80:80 : the port we are exposing and mapping from local machine port number to that of container, in the format local_machine_port:container_port-d : Detached mode – Runs the container in background
root@arjun-VPCEH26EN:/home/arjun# docker run --name docker-nginx -p 80:80 -d nginx 26676407c03db63a74b7ccf17796d034bcd2ffd909a568585f3047e2d52d091c
Now the NGINX is running in its default configuration. If you open a browser and hit the url0.0.0.0:80, you would get following welcome page from NGINX Web Server.
4. Include a static Web Application in the Docker with NGINX
To include our static Web Application into the Docker Image with NGINX, we shall create a Dockerfile (including commands to build image) and an html file with name index.html (acting as our web application) in a directory named nginx-app.
FROM nginx COPY . /usr/share/nginx/html

$ docker build -t nginx-application .

Run the following command in Terminal from directory, to run the image file in a container.
$ docker run --name docker-nginx -p 80:80 -d nginx-application
nginx-application – Docker Image file name.
root@arjun-VPCEH26EN:/home/arjun/workspace/docker/nginx-app# docker run --name docker-nginx -p 80:80 -d nginx-application 1a2ddec91961b76b73e19af28db06e658afcbe2a44e3ae01205d55f9d910922f
The container docker-nginx is running.

Hit the url0.0.0.0:80/index.html in any of your browser.
Conclusion
In this NGINX Tutorial – Docker NGINX, we have learnt to deploy NGINX with Docker
