Environment variables

A list of environment variables that are defined in the Cloud Functions runtime environment and can be used by functions.

Key Value
_HANDLER The handler location specified for the function.
AWS_LAMBDA_RUNTIME_API The runtime host and API port.
LAMBDA_RUNTIME_DIR The path to the runtime libraries.
LAMBDA_TASK_ROOT The path to your function code.
PATH The set of folders with executable files.

You can add environment variables in the management console.

User files

User files are stored in two directories:

  • /function/code: The user's working directory. It contains all the code of your function and all the files uploaded as a ZIP archive. You can use a relative path to access it.
  • /tmp: A directory to store temporary files used for optimizing repeated function instance calls. The maximum size of temporary files is limited to 512 MB.
