This is a simple go program to demonstrate using the modules feature of golang.

• latest golang version with support for go modules (1.12.6)

• Access to internet to clone the github project

• Development machine

1. Run git clone https://github.com/jfrogtraining/go-swampup-service and change to the go-swampup-service directory

2. git checkout -b

3. go build -v ./...

4. You can manually run the service by typing ./go-swampup-service

5. Test by running a GET on http://localhost:7888

3. go mod tidy

4. Edit main.go and uncomment the lines as instructed.

5. Also comment out as instructed.

7. git add main.go; git add go.mod; git add go.sum

8. git commit -m "go modules test"
