## Note

1. We need use cross build for Go app to build then run on a different environment.

```sh
# for local dev: build on local machine(MacOS) and run on VM server (Linux-CentOS)
GOOS=linux GOARCH=amd64 go build -o webapp

# for workflow: build in Github actions runner (latest-Ubuntu) and run on VM server (Linux-CentOS)
# use static linking to create a standalone binary that doesn't depend on dynamic libraries.
go build -ldflags="-linkmode external -extldflags -static" -o webapp
