# Build a Lambda function !cargo lambda build --release # Deploy to AWS !cargo lambda deploy --iam-role arn:aws:iam::123456789012:role/lambda-role # Invoke locally !cargo lambda invoke --data-file payload.json

cargo lambda --version

Debug

Known issues

gotchacargo-lambda requires Zig for cross-compilation to AWS Lambda's Amazon Linux 2 environment. Without Zig, builds may fail or produce incompatible binaries.

fix

Install Zig (e.g., via brew install zig or download from ziglang.org) and ensure it's in PATH.

affects: all

breakingIn v1.8.0, the '--iam-role' flag for 'cargo lambda deploy' changed behavior: it now only sets the role on initial creation, not on subsequent updates. To update an existing function's role, use 'cargo lambda update --iam-role'.

fix

Use 'cargo lambda update --iam-role arn:aws:iam::...' instead of 'deploy' for existing functions.

affects: >=1.8.0
