Test application

go test ./...

Build application

• <os> should contain the target OS, examples: linux, darwin and windows.
• <arch> should contain the target architecture, examples: amd64 and arm64.

CGO_ENABLED=0 GOOS=<os> GOARCH=<arch> go build -o endpoint -o build/endpoint main.go

Build Dockerfile

• <version> should contain a version number, example: 1.0.0.

docker build -t endpoint:<version> .

Run application

Run application with Go

Run the application without compiling it with Go:

go run main.go

Run application from binary

Run the application from the binary file (assuming it is built):

cd build
./endpoint

# Or
./build/endpoint

Run application with Docker

• <version> should contain a version number, example: 1.0.0. The same as used when building the Dockerfile.
