Update a Lambda function

Use GitHub Actions to deploy a Lambda Image or S3 bucket update

Instead of deploying your Lambda code in the same pipeline as your infrastructure, you can use CI/CD and GitHub Actions pipelines. With DuploCloud's GitHub Actions integration, you can build and deploy Lambda functions in your AWS account by deploying a Lambda image or by a package uploaded to an S3 bucket.

For general information about deploying serverless applications with GitHub Actions in AWS, reference this blog.

Update a Function Using an Image

Use the following code as a template to update a Lambda container image with GitHub Actions. In this example, the Lambda container image in the dev01 The tenant is updated and redeployed.

You must ensure the following are configured in your environment and your specific situation.

The name of lambda is set on the action to your actual lambda

Update Lambda based on a package in Amazon S3

Use the following code as a template to deploy your Lambda functions to an S3 bucket with GitHub Actions. In this example, the Lambda in the dev01 The tenant is updated using an S3 bucket that contains mylambda-v1.zip

You must ensure the following are configured in your environment and your specific situation.
