where can I see the lambda code that fit for example to this templete : https://github.com/Netflix/metaflow-tools/blob/master/aws/cloudformation/metaflow-cfn-template.yml or maybe I need to change the code base on my need another question : what is the contribution of VPC in this template?

many AWS services require a VPC (like Sagemaker notebooks) so some value is needed

thanks

if you want to have a custom lambda script. it is probably easiest to have it in a separate template. Metaflow doesn't use Lambdas for anything currently
