ARM64 #57

Closed aterreno closed 2 years ago

aterreno commented 2 years ago

Am I right in saying that the lambda extension layer won't work on ARM64/graviton processors?

Thanks

A Lambda extension layer is just files. If the files within the layer are compatible with ARM64/Graviton2 then the extension will work. Interpreted languages like Node/Python work without modification. If you're building extensions using binaries, these will need to be rebuild for arm64.

thanks @julianwood - I tried the lambda extension layer some time ago (in combination with datadog layer) and I had issues

we got back:

fork/exec /opt/extensions/cloudwatch_lambda_agent: exec format error

Although this might not be the right repository, I can't find where else I should raise this with AWS

Are you using CloudWatch Lambda Insights? The extension for this was only updated yesterday to work with Graviton2. Currently we're waiting for CloudFormation and CDK/SAM support to be rolled out. You should be able to deselect in the console and select again which will add the correct Graviton2 supported Lambda layer.

Oh amazing news, I had to remove it to be able to move all our lambdas to Graviton

Just in case anyone else stumbles here and they are using terraform or pulumi to manage their infra, the arn for the layer is:

arn:aws:lambda:us-east-1:580247275435:layer:LambdaInsightsExtension-Arm64:1

or whatever region your lambda is deployed into :)

Thanks, glad you're sorted!
