While Kubeless comes up, install the Kubeless binary to launch functions in the Kubernetes cluster by running the following command:

export RELEASE=$(curl -s https://api.github.com/repos/kubeless/kubeless/releases/latest | grep tag_name | cut -d '"' -f 4)
export OS=$(uname -s| tr '[:upper:]' '[:lower:]')
curl -OL https://github.com/kubeless/kubeless/releases/download/$RELEASE/kubeless_$OS-amd64.zip &&   unzip kubeless_$OS-amd64.zip && mkdir -p ~/local/bin &&  mv bundles/kubeless_$OS-amd64/kubeless ~/local/bin/ && export PATH=$PATH:~/local/bin

Ensure that the kubeless framework is installed properly by running the following command:

kubeless --help

NOTES:

== Deploy function

In order to deploy a function you need the kubeless binary.
You can download it from the kubeless repo:

https://github.com/kubeless/kubeless

Great! We are good to go to deploy our first serverless function.
