tl;dr
Environment variables set in a zappa_settings.json don't upload as environment variables to AWS Lambda. Where do they go?
ts;wm
I have a Lambda function configured, deployed and managed using the Zappa framework. In the zappa_settings.json I have set a number of environment variables. These variables are definitely present as my application successfully runs however, when trying to inspect the Lambda function environment variables in the console or AWS CLI I see no environment variables have been uploaded to the Lambda function itself.
Extract from zappa_settings.json:
{
"stage-dev": {
"app_function": "project.app",
"project_name": "my-project",
"runtime": "python3.7",
"s3_bucket": "my-project-zappa",
"slim_handler": true,
"environment_variables": {
"SECRET": "mysecretvalue"
}
}
}
Output of aws lambda get-function-configuration --function-name my-project-stage-dev:
{
"Configuration": {
"FunctionName": "my-project-stage-dev",
"FunctionArn": "arn:aws:lambda:eu-west-1:000000000000:function:my-project-stage-dev",
"Runtime": "python3.7",
"Role": "arn:aws:iam::000000000000:role/lambda-execution-role",
"Handler": "handler.lambda_handler",
"CodeSize": 12333025,
"Description": "Zappa Deployment",
"Timeout": 30,
"MemorySize": 512,
"LastModified": "...",
"CodeSha256": "...",
"Version": "$LATEST",
"TracingConfig": {
"Mode": "PassThrough"
},
"RevisionId": "..."
},
"Code": {
"RepositoryType": "S3",
"Location": "..."
}
}
Environment is absent from the output despite being included in the zappa_settings and the AWS documentation indicating it should be included if present, this is confirmed by checking in the console. I want to know where zappa is uploading the environment variables to, and if possible why it is doing so over using Lambda's in-built environment?
