GitHub Actions - AWS Lambda deploy template

This is a template repository for quickly creating an Actions-deployed AWS Lambda function.

Every push to the master branch will be automatically deployed to AWS.

Setup

Go to AWS Lambda console and create a new function. Select runtime as Python 3.8 and configure triggers as needed. If you need a more detailed guide, check out my blog for configuring API Gateway with Lambda.

Go to AWS IAM console and create a new policy. Here's an example JSON that you can copy:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:PutObject",
        "iam:ListRoles",
        "lambda:UpdateFunctionCode",
        "lambda:CreateFunction"
      ],
      "Resource": "*"
    }
  ]
}

Also on the IAM console, create a new user and attach the policy from the above step. Create a pair of access keys for the new user.

Create a new repo from this template. Go to the Settings tab of your new repository and add the following secrets:

Name	Description
AWS_ACCESS_KEY_ID	AWS access key ID
AWS_SECRET_ACCESS_KEY	AWS secret access key
AWS_FUNCTION_NAME	Name of your Lambda function

Now write your code and push. GitHub Actions should automatically deploy your code to your specified function.

Be aware that non-secret environment variables configured for your Lambda function will be printed out. You can edit Makefile as needed.
