Deploying to AWS Lambda from GitHub Actions 🚀

Okay, so like, if you wanna deploy your cool project to AWS Lambda using GitHub Actions, here’s a step-by-step thingy that even a rookie can follow! No worries if you’re not a pro yet!

Step 1: Set Up AWS

First off, you gotta have an AWS account. Go to aws.amazon.com and create one if you don’t have it yet. Then, create a Lambda function. You can just choose the default options for now. Important!

Step 2: Get Your AWS Credentials

You’ll need some keys to talk to AWS. Go to the IAM (Identity and Access Management) section, create a user, and give it permissions to deploy to Lambda. You’ll get an access key and secret key. Save those somewhere safe!

Step 3: GitHub Secrets

Now, head over to your GitHub repo and click on “Settings”. Look for “Secrets” (under Security). You’ll add these secrets:

• AWS_ACCESS_KEY_ID: (your access key)
• AWS_SECRET_ACCESS_KEY: (your secret key)
• AWS_REGION: (like us-east-1, or whatever region you chose)
• AWS_FUNCTION_NAME: (the name of your Lambda function)

Step 4: Create Your GitHub Action

In your repo, make a folder named .github/workflows if it doesn’t exist. Now create a file inside called deploy.yml. Here’s a simple version of what it might look like:

    
name: Deploy to AWS Lambda

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Set up Node.js
        uses: actions/setup-node@v2
        with:
          node-version: '14'

      - name: Install dependencies
        run: npm install

      - name: Deploy to AWS Lambda
        uses: appleboy/scp-action@master
        env:
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          AWS_REGION: ${{ secrets.AWS_REGION }}
          AWS_FUNCTION_NAME: ${{ secrets.AWS_FUNCTION_NAME }}
        with:
          args: lambda update-function-code --function-name $AWS_FUNCTION_NAME --zip-file fileb://function.zip
    
  

Step 5: Zip Your Function

Make sure your Lambda function is zipped. If you’re using Node.js, you might need to do something like zip -r function.zip . on your code folder. Update the action if your file name is different!

Step 6: Push Your Code

Finally, push your code to GitHub! Just do a git add, git commit, and git push. If everything is right, GitHub Actions should start running and deploy your Lambda function! 🎉

Good Luck!

Do some testing to see if it all works. If it breaks, don’t sweat it! Just check the logs and keep tweaking. You got this!
