Deploying a Static Website In a Container and Ship it any Anywhere

What is Docker?

Ans: Docker is a set of platform as a service products that use virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files.

Steps that we are going to perform:

Creating Docker file
Create an image of our static website with use of Docker file
Push that image to Docker Hub
Run that container on Server

Creating Docker File:

FROM nginx:latest
COPY . /usr/share/nginx/html
EXPOSE 80
CMD [“nginx”,”-g”,”daemon off;”]

FROM — is where we are pulling our official image from nginx is an official image provided by Docker

COPY — is taking our all file from out local directory were are working in and moves it into the /usr/share/nginx/html directory(of NGINX) in our container.

EXPOSE- is a instruction letting the container know we are exposing the port 80 (TCP)

CMD- provide defaults for an executing container

Create an image of our static website with use of Docker file:

For that we have to execute command and that is:

docker build -t "<name of image you have to put>" .

This command means :

-t = Tag
"" = your image name
. = it will take dockerfile form present location.

So in my case, I am going to give image name as nipun2020/docker-community-rajkot

command will be for me :)

docker build -t nipun2020/docker-community-rajkot .

Push that image to Docker Hub

To push our image in docker hub for that we will use this command

docker push

in my case it will be ->

docker push nipun2020/docker-community-rajkot

Run that container on Server

and just hit this command and your container will be running on your server.

docker run -p 80:80 nipun2020/docker-community-rajkot

So by use of this command your static website will be running with the use of Docker.

Demo of static site is hosted:

CDN Invalidation using AWS Lambda Function

Nipun Parekh — Sat, 22 May 2021 08:29:42 +0000

Steps to create Invalidation using lambda function are:

Create a Lambda Function and write a code.
Create an API Gateway / API from which we are going to create Invalidation of CDN

Step:1
Creating a Lambda Function:

Just give a name of the function and use the Runtime of python 3.8 and put rest all things as it is.

Now Click on Create Button and Your Function is created.

When you go inside a function you will find this window.

Paste this code inside the code area.

from future import print_function

import boto3
import time

def lambda_handler(event, context):
client = boto3.client(‘cloudfront’)
path = “/*”
invalidation = client.create_invalidation(DistributionId=”Put your CDN ID”,
InvalidationBatch={
‘Paths’: {
‘Quantity’: 1,
‘Items’: [path]
},
‘CallerReference’: str(time.time())
})

You will get your CDN ID from Cloudfront Dashboard like this

Now attach the Cloudfront full access policy to our lambda policy like this.

We have completed step 1.

Step:2

Create an API for that you have to use AWS API Gateway Service.

Create HTTP API.

The Integration, section adds lambda and selects your lambda function in my case it is an invalidation name of the function.

And rest all thing keep as it is and create an API.

We have successfully completed all the steps.

Now come to the lambda function and reload our lambda function page and you will get our API Gateway in the trigger section like this

Now Click on API Gateway you will get something page like this:

Click on API Endpoint and execute this URL in the browser and here your CDN invalidation is created.

You can check it like this:

So here we Created a CND Invalidation using AWS Lambda Function.
