Bootstrap a Go Cobra application with Go Modules

To bootstrap a Go application using Cobra Generator and Go Modules, start by installing the Cobra command line:

# Install Cobra
go get github.com/spf13/cobra/cobra

Initialize your Cobra project, but remember to use your package’s fully qualified name, as in: github.com/laurybueno/kubectl-hoggers. Don’t worry if your package is not publicly available yet. And there is no need to put your source code inside GOPATH anymore (since Go 1.11 at least):

cobra init --pkg-name <fully_qualified_package_name>

Initialize your new module:

go mod init <fully_qualified_package_name>

Get recursively all its dependencies and install it:

go get -d -v ./...
go install -v ./...

Your app’s command line is now ready to be used:

kubectl-hoggers
