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 url 0.0.0.0:80, 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

Run the following command in Terminal from directory – nginx-app, to create image file.
$ 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.
root@arjun-VPCEH26EN:/home/arjun/workspace/docker/nginx-app# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 1a2ddec91961 nginx-application "nginx -g 'daemon ..." About an hour ago Up About an hour 0.0.0.0:80->80/tcp docker-nginx
Hit the url 0.0.0.0:80/index.html in any of your browser.
Conclusion
In this NGINX Tutorial – Docker NGINX, we have learnt to deploy NGINX with Docker
