Requirements

• dep
• go 1.12 or higher
• docker

Building Go Binary

dep ensure
make

Output is saved to bin, and the shared library will be compatible with your local environment. If you want to build a linux compatible binary, you will need to use docker, (setting GOOS/GOARCH enviornment variable doesn't work for shared libraries).

./scripts/build_linux_go_bin.sh

Lambda Layer

Building Lambda Layer

You can build the lambda layer with the following command

./scripts/build_layers.sh

Publishing to staging

./scripts/publish_staging.sh

Publishing to prod

./scripts/publish_prod.sh
