Kubernetes for Serverless Applications

By: Russ McKendrick

Overview of this book

Kubernetes has established itself as the standard platform for container management, orchestration, and deployment. It has been adopted by companies such as Google, its original developers, and Microsoft as an integral part of their public cloud platforms, so that you can develop for Kubernetes and not worry about being locked into a single vendor. This book will initially start by introducing serverless functions. Then you will configure tools such as Minikube to run Kubernetes. Once you are up-and-running, you will install and configure Kubeless, your first step towards running Function as a Service (FaaS) on Kubernetes. Then you will gradually move towards running Fission, a framework used for managing serverless functions on Kubernetes environments. Towards the end of the book, you will also work with Kubernetes functions on public and private clouds. By the end of this book, we will have mastered using Function as a Service on Kubernetes environments.

Running Fission locally

Now that we have the prerequisites installed we can look at creating our first function. To do this we are going to use Minikube. To launch the single node cluster we simply need to run the following:

$ minikube start
$ kubectl get nodes

This should launch your Minikube cluster and also confirm that your local version has been reconfigured to communicate with it:

Once we have our cluster running and accessible we need to complete the Helm installation by installing Tiller. To do this we need to run the following:

$ helm init

You should see something like the following message:

Launching Fission using Helm

Helm is now configured and we can use it to deploy the remote components of Fission. This can...
