gURL - A cURL replacement developed in Go

This is developed because, the default curl binary provided via the Alpine packages registry doesn't support kerberos authentication.

NOTE: It supports just the GET method currently

---

gURL can be statically compiled for Linux

env CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -mod=vendor -a -installsuffix cgo -gcflags=all='-l -B' -ldflags '-s -w' -o gurl

Building the docker container

docker build --build-arg BASE_IMAGE_VERSION=3.16 --build-arg ALPINE_VERSION=3.16 --build-arg GO_VERSION=1.19 -t gurl:latest .
