What are Lambda layers and how does versioning work?
Lambda layers are a way to package and share code and dependencies across multiple Lambda functions. Versioning allows you to manage different iterations of a layer, ensuring that your functions can use the specific version they need.
How do I create a new version of a Lambda layer?
To create a new version of a Lambda layer, you can use the AWS Management Console, AWS CLI, or SDKs. You upload your layer code and dependencies, and then publish it as a new version.
Can I roll back to a previous version of a Lambda layer?
Yes, you can roll back to a previous version of a Lambda layer by updating your Lambda function to use the specific version ARN of the layer you want to revert to.
Are there any limits on the number of versions I can create?
Yes, AWS has limits on the number of versions you can create for a Lambda layer, typically up to 50 versions per layer.
