NGSI Go tutorial

Getting Started with NGSI Go

Start

git clone https://github.com/lets-fiware/ngsi-go.git
cd ngsi-go
script/tutorial.sh start

If CrateDB exits immediately with a max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] error, this can be fixed by running the sudo sysctl -w vm.max_map_count=262144 command on the host machine. For further information look within the CrateDB documentation and Docker troubleshooting guide
