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

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

Run the following command in Terminal from directory – nginx-app, to create image file.

$ docker build -t nginx-application .
root@arjun-VPCEH26EN:/home/arjun/workspace/docker/nginx-app# 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

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

Hit the url0.0.0.0:80/index.html in any of your browser.
