With increase of cloud applications in complexity and delivery cycles gets faster, teams reorganizes into a distributed micro-service architecture and software delivery cycles get faster.

Throughout this, DevOps engineers keep looking for ways to streamline and automate the continuous deployment of code using containers like Docker.

Docker simplifies and automate the deployment process of their application. it is an effective way of packaging software in a way that is predictable and consistent. You will experience the similar environment while using  both cloud and local environment.

You can expect the software to behave similarly whether you’re on a laptop or in the cloud.

Docker has become so mainstream in the short time since it debuted in 2013 that the big giants like Amazon, Cisco, Google, Microsoft Red Hat, VMWare, and others have created the Open Container Initiative to develop a common standard around it.

Steps to deploy custom docker Image

• Create a directory for the HTML (Example)
• Create a file called Dockerfile
• Build the Docker Image for the HTML Server
• Run the Docker Container
• Verify the container with cURL

Let’s do it!!

1. Create a Directory for the Website

Make sure that you have your HTML files already in the current directory

or You can download the sample html from GitHub repo,

Open your terminal

#git clone https://github.com/ashokkuikel/html-to-docker

# cd html-to-docker

And it should show you output something like this:

HTML Sample Code Repository

https://github.com/ashokkuikel/html-to-docker

2. Create a file called Dockerfile

Place the following contents into the Dockerfile

FROM nginx:alpine
COPY . /usr/share/nginx/html

These lines of code represent the image and we’re going to use along with copying the contents of the current directory into the container.

3. Build the Docker Image for the HTML Server

Run the following command:

docker build -t html-to-docker:v1 .

And it should show you output something like this:

You can confirm that this has worked by running the command:

docker images

And it should show you output something like this:

4. Run the Docker Container

Run the following command to run the HTML container server:

docker run -d -p 80:80 html-to-docker:v1

5. Verify the container with cURL

Run the following command to ensure the server is running:

curl localhost 

or

curl localhost:80

You can also view it in the browser now by going to localhost and you should see your HTML file, as shown below:

Congratulations !! Your Docker Image has been successfully  deployed.
