Setting Up AWS

Amazon Web Services (AWS) is the backbone of our PySpark deployment, and we’ll use two essential services, Elastic Container Registry (ECR) and Elastic Compute Cloud (EC2), to create a dynamic cloud environment.

"

AWS Account Registration

If you haven’t already, head to the AWS sign-up page to create an account. Please follow the registration process, provide the necessary information, and be ready with your payment details if you’d like to explore beyond the AWS Free Tier.

AWS Free Tier

For those new to AWS, take advantage of the AWS Free Tier, which offers limited resources and services at no cost for 12 months. This is an excellent way to explore AWS without incurring charges.

AWS Access Key and Secret Key

You’ll need an Access Key ID and Secret Access Key to interact with AWS programmatically. Follow these steps to generate them:

  • Log in to the AWS Management Console.
  • Navigate to the Identity & Access Management (IAM) service.
  • Click on “Users” in the left navigation pane.
  • Create a new user or select an existing one.
  • Under the “Security credentials” tab, generate an Access Key.
  • Note down the Access Key ID and Secret Access Key, as we’ll use them later
  • After click user
"

Elastic Container Registry (ECR)

ECR is a managed Docker container registry service provided by AWS. It will be our repository for storing Docker images. You can set up your ECR by following these steps:

  • In the AWS Management Console, navigate to the Amazon ECR service.
  • Please create a new repository, give it a name, and configure the repository settings.
  • Note down the URI of your ECR repository; you’ll need it for Docker image pushes.

Elastic Compute Cloud (EC2)

EC2 provides scalable computing capacity in the cloud and will host your PySpark applications. To set up an EC2 instance:

  • In the AWS Management Console, navigate to the EC2 service.
  • Launch a new EC2 instance, choosing the instance type that suits your workload.
  • Configure the instance details and storage options.
  • Create or select an existing key pair to securely connect to your EC2 instance.

Storing Your AWS Setup Values for Future Use

AWS_ACCESS_KEY_ID: AKIAYOURSAMPLEACCESSKEY
AWS_ECR_LOGIN_URI: 123456789012.dkr.ecr.region.amazonaws.com
AWS_REGION: us-east-1
AWS_SECRET_ACCESS_KEY: YOURSAMPLESECRETACCESSKEY12345
ECR_REPOSITORY_NAME: your-ecr-repository-name

Setting Up GitHub Secrets and Variables

Now that you have your AWS setup values ready, it’s time to securely configure them in your GitHub repository using GitHub secrets and variables. This adds an extra layer of security and convenience to your PySpark deployment process.

Follow these steps to set up your AWS values:

Access Your GitHub Repository

  • You can just navigate to your GitHub repository, where you’re hosting your PySpark project.
"

Access Repository Settings

  • Inside your repository, click on the “Settings” tab.

Secrets Management

  • In the left sidebar, you’ll find an option called “Secrets.” Click on it to access the GitHub secrets management interface.
"

Add a New Secret

  • Here, you can add your AWS setup values as secrets.
  • Click on “New Repository Secret” to create a new secret.
  • For each AWS value, create a secret with a name that corresponds to the value’s purpose (e.g., “AWS_ACCESS_KEY_ID,” “AWS_SECRET_ACCESS_KEY,” “AWS_REGION,” etc.).
  • Enter the actual value in the “Value” field.
"

Save Your Secrets

  • Click the “Add secret” button for each value to save it as a GitHub secret.

With your AWS secrets securely stored in GitHub, you can easily reference them in your GitHub Actions workflows and securely access AWS services during deployment.

Best Practice

  • GitHub secrets are encrypted and can only be accessed by authorized users with the necessary permissions. This ensures the security of your sensitive AWS values.
  • Using GitHub secrets, you avoid exposing sensitive information directly in your code or configuration files, enhancing your project’s security.

Your AWS setup values are now safely configured in your GitHub repository, making them readily available for your PySpark deployment workflow.

  • They automate the build, testing, and deployment processes.
  • Workflow files, such as main.yml, outline the steps to execute when specific events occur, such as code pushes or pull requests.

Build  py_sparkmanager.py

import os
from dotenv import load_dotenv
from pyspark.sql import SparkSession

# Load environment variables from .env
load_dotenv()

access_key_id = os.getenv("AWS_ACCESS_KEY_ID")
secret_access_key = os.getenv("AWS_SECRET_ACCESS_KEY")

# Initialize SparkSession
spark_session = SparkSession.builder.master('local[*]').appName('consumer_complaint') \
    .config("spark.executor.instances", "1") \
    .config("spark.executor.memory", "6g") \
    .config("spark.driver.memory", "6g") \
    .config("spark.executor.memoryOverhead", "8g") \
    .config('spark.jars.packages', "com.amazonaws:aws-java-sdk:1.7.4,
	org.apache.hadoop:hadoop-aws:2.7.3") \
    .getOrCreate()

# Configure SparkSession for AWS S3 access
spark_session._jsc.hadoopConfiguration().set("fs.s3a.awsAccessKeyId", access_key_id)
spark_session._jsc.hadoopConfiguration().set("fs.s3a.awsSecretAccessKey", secret_access_key)
spark_session._jsc.hadoopConfiguration().set("fs.s3a.impl", 
				"org.apache.hadoop.fs.s3a.S3AFileSystem")
spark_session._jsc.hadoopConfiguration().set("com.amazonaws.services.s3.enableV4", "true")
spark_session._jsc.hadoopConfiguration().set("fs.s3a.aws.credentials.provider",

spark_session._jsc.hadoopConfiguration().set("fs.s3a.endpoint", "ap-south-1.amazonaws.com")
spark_session._jsc.hadoopConfiguration().set("fs.s3.buffer.dir", "tmp")

This code sets up your SparkSession, configures it for AWS S3 access, and loads AWS credentials from environment variables, allowing you to work with AWS services seamlessly in your PySpark application

Preparing PySpark Docker Images(IMP)

This section will explore how to create Docker images that encapsulate your PySpark application, making it portable, scalable, and ready for deployment on AWS. Docker containers provide a consistent environment for your PySpark applications, ensuring seamless execution in various settings.

Dockerfile

The key to building Docker images for PySpark is a well-defined Dockerfile. This file specifies the instructions for setting up the container environment, including Python and PySpark dependencies.

FROM python:3.8.5-slim-buster
# Use an Ubuntu base image
FROM ubuntu:20.04

# Set JAVA_HOME and install OpenJDK 8
ENV JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/
RUN apt-get update -y \
    && apt-get install -y openjdk-8-jdk \
    && apt-get install python3-pip -y \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

# Set environment variables for your application
ENV AIRFLOW_HOME="/app/airflow"
ENV PYSPARK_PYTHON=/usr/bin/python3
ENV PYSPARK_DRIVER_PYTHON=/usr/bin/python3

# Create a directory for your application and set it as the working directory
WORKDIR /app

# Copy the contents of the current directory to the working directory in the container
COPY . /app

# Install Python dependencies from requirements.txt
RUN pip3 install -r requirements.txt

# Set the entry point to run your app.py script
CMD ["python3", "app.py"]

Building the Docker Image

Once you have your Dockerfile ready, you can build the Docker image using the following command:

docker build -t your-image-name

Replace your-image-name with the desired name and version for your Docker image.

Verifying the Local Image

After building the image, you can list your local Docker images using the following command:

docker images

docker ps -a 

docker system df

Running PySpark in Docker

With your Docker image prepared, you can go ahead and run your PySpark application in a Docker container. Use the following command:

docker run -your-image-name

“”” SOMETIME docker run COMMAND NOT WORK FOLLOW BELOW COMMAND. “””

docker run 80:8080 your-image-name

docker run 8080:8080 your-image-name

Deploying PySpark on AWS

This section will walk through deploying your PySpark application on AWS using Docker containers. This deployment will involve launching Amazon Elastic Compute Cloud (EC2) instances for creating a PySpark cluster.

Launch EC2 Instances

  • In the EC2 Dashboard, click “Launch Instances.”
  • You can select an Amazon Machine Image (AMI) that suits your needs, often Linux-based.
  • Depending on your workload, choose the instance type (e.g., m5.large, c5.xlarge).
  • Configure instance details, including the number of instances in your cluster.
  • Add storage, tags, and security groups as needed.

This is all I mentioned above.

Connect to EC2 Instances

  • Once the instances run, you can SSH into them to manage your PySpark cluster.

Building a GitHub Self-Hosted Runner

We’ll set up a self-hosted runner for GitHub Actions, responsible for executing your CI/CD workflows. A self-hosted runner runs on your infrastructure and is a good choice for running workflows that require specific configurations or access to local resources.

Setting Up the Self-Hosted Runner

  • Click Setting
  • Click Action -> Runner
"
  • Click New self-hosted Runner

Write the below command on the EC2 machine

  • Create a folder: This command creates a directory named actions-runner and changes the current directory to this newly created folder.
$ mkdir actions-runner && cd actions-runner
  • Download the latest runner package: This command downloads the GitHub Actions runner package for Linux x64. It specifies the URL of the package to download and saves it with the filename actions-runner-linux-x64-2.309.0.tar.gz.
$ curl -o actions-runner-linux-x64-2.309.0.tar.gz -L 
https://github.com/actions/runner/releases/download/v2.309.0/actions-runner-linux-x64-2.309.0.tar.gz
  • Optional: Validate the hash: This command checks the integrity of the downloaded package by validating its hash. It computes the SHA-256 hash of the downloaded package and compares it to a known, expected hash. If they match, the package is considered valid.
$ echo "2974243bab2a282349ac833475d241d5273605d3628f0685bd07fb5530f9bb1a
  actions-runner-linux-x64-2.309.0.tar.gz" | shasum -a 256 -c
  • Extract the installer: This command extracts the contents of the downloaded package, which is a tarball (compressed archive).
$ tar xzf ./actions-runner-linux-x64-2.309.0.tar.gz
  • Last step, run it: This command starts the runner with the provided configuration settings. It sets up the runner to execute GitHub Actions workflows for the specified repository.
$ ./run.sh

Continuous Integration and Continuous Delivery (CICD) Workflow Configuration

In a CI/CD pipeline, the build.yaml file is crucial in defining the steps required to build and deploy your application. This configuration file specifies the workflow for your CI/CD process, including how code is built, tested, and deployed. Let’s dive into the critical aspects of the build.yaml configuration and its importance:

Workflow Overview

The build.yaml file outlines the tasks executed during the CI/CD pipeline. It defines the steps for continuous integration, which involves building and testing your application and continuous delivery, where the application is deployed to various environments.

Continuous Integration (CI)

This phase typically includes tasks like code compilation, unit testing, and code quality checks. The build.yaml file specifies the tools, scripts, and commands required to perform these tasks. For example, it might trigger the execution of unit tests to ensure code quality.

Continuous Delivery (CD)

After successful CI, the CD phase involves deploying the application to different environments, such as staging or production. The build.yaml file specifies how the deployment should happen, including where and when to deploy and which configurations to use.

"

Dependency Management

The build.yaml file often includes details about project dependencies. It defines where to fetch external libraries or dependencies from, which can be crucial for the successful build and deployment of the application.

Environment Variables

CI/CD workflows often require environment-specific configurations, such as API keys or connection strings. The build.yaml file may define how these environment variables are set for each pipeline stage.

Notifications and Alerts

In case of failures or issues during the CI/CD process, notifications and alerts are essential. The build.yaml file can configure how and to whom these alerts are sent, ensuring that problems are addressed promptly.

Artifacts and Outputs

Depending on the CI/CD workflow, the build.yaml file may specify what artifacts or build outputs should be generated and where they should be stored. These artifacts can be used for deployments or further testing.

By understanding the build.yaml file and its components, you can effectively manage and customize your CI/CD workflow to meet the needs of your project. It is the blueprint for the entire automation process, from code changes to production deployments.

CI/CD Pipeline

You can customize the content further based on the specific details of your build.yaml configuration and how it fits into your CI/CD pipeline.
