How do I excluded folder from sam deploy command?

Question

I run this to deploy my lambda:

sam package --template-file prod_template.yaml --s3-bucket mybucket --output-template-file packaged-template.yaml
sam deploy --template-file packaged-template.yaml --stack-name mystack --capabilities CAPABILITY_IAM

That works but this code is version controlled and sam is also uploading the .git folder. How do I have sam ignore some folders like I can with gitignore?

You need to check you're supplying a valid CodeUri path in your template, it should look something like this:

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Resources:
  Followers:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: ./src
      Handler: lambda.handler
      Runtime: nodejs12.x
      Timeout: 300

The AWS docs state that if the CodeUri is not supplied, the entire working directory will be zipped and uploaded (which I think is what you're experiencing).

If you specify a file [in CodeUri], the command directly uploads it to the S3 bucket. If you specify a folder, the command zips the folder and then uploads the .zip file. For most resources, if you don't specify a path, the command zips and uploads the current working directory.
