Setup Provisioned Concurrency GitHub Action

This GitHub Action sets up and cleans up provisioned concurrency for a specified AWS Lambda function. It automatically publishes a new version of the Lambda function, sets up provisioned concurrency for that version, and deletes older versions along with their provisioned concurrency configurations.

Prerequisites

• The AWS Lambda function must already exist.
• AWS credentials must be configured before running this action.
• We recommend using aws-actions/configure-aws-credentials for this.

IAM Permissions

The AWS credentials used must have the following IAM permissions:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "lambda:PublishVersion",
        "lambda:PutProvisionedConcurrencyConfig",
        "lambda:ListVersionsByFunction",
        "lambda:DeleteProvisionedConcurrencyConfig",
        "lambda:DeleteFunction"
      ],
      "Resource": "arn:aws:lambda:REGION:ACCOUNT_ID:function:FUNCTION_NAME"
    }
  ]
}

Replace REGION, ACCOUNT_ID, and FUNCTION_NAME with your AWS region, account ID, and the name of your Lambda function, respectively.

Usage

Here's a sample workflow to demonstrate how to use this action:

name: Setup Provisioned Concurrency

on:
  push:
    branches:
      - main

jobs:
  setup:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout code
      uses: actions/checkout@v3

    - name: Configure AWS credentials
      uses: aws-actions/configure-aws-credentials@v3
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: us-west-2

    - name: Deploy Chalice App
      run: |
        cd my-app/
        chalice deploy        

    - name: Setup Provisioned Concurrency
      uses: IronCloud/setup-provisioned-concurrency@v2
      with:
        function-name: 'your-lambda-function-name'
        provisioned-concurrency: 5

Replace your-github-username with your GitHub username and your-lambda-function-name with the name of your Lambda function.
