NDS Labs API/CLI requirements

Starting the API server

eval $(docker run --rm -t ndslabs/system-shell usage docker)
git clone https://github.com/craig-willis/ndslabs-startup
cd ndslabs-startup
./kube-up.sh
If needed, download the latest copy of ndslabsctl
- wget https://github.
/ndslabs-up.sh

The ndslabs-up.sh will create a ~/bin directory and download the latest version of the ndslabsctl binary. A file ~/.ndslabsctl.yaml is also created containing the API server address from Kubernetes.

If you are not using the ndslabs-startup.sh script, you will need to manually download the ndslabsctl from Github: https://github.com/nds-org/ndslabs/releases/tag/v1.0-alpha.

If the API server is running under docker or Kubernetes, you will need to specify the server address. This can be done on the commandline using the --server flag or by creating a .ndslabsctl.yaml file in your home directory. For example:

APISERVER=`kubectl describe svc ndslabs-apiserver | grep ^IP | awk '{print $2}'`

echo "server: http://$APISERVER:8083" > ~/.ndslabsctl.yaml

Global preconditions
