Pivotal Function Service (PFS) Hands on Workshop

Product Page | Knative | Kubernetes

This workshop will get a short and quick introduction to serverless programmin using PFS. PFS is based on knative.

K8s is Kubernetes
Knative is Kubernetes based serverless framework
Istio is a service mesh framework. It was initially designed for Kubernetes, but it can be used on other container platforms, example Cloud Foundry / Pivotal Application Service
Knative uses Istio to manage routing
PFS is based on Knative. It adds:
- Builds via Cloud Native Buildpack
- Spring Invoker

Requirement

Github account
Linux environment
(Optional) Codeanywhere Account
(Optional) Google Cloud Platform Account

Setup

You will need following tools to complete exercises in this workshop:

Linux or Mac environment (required)
git
kubectl
pfs
curl
Text Editor / IDE

If you do not have a linux/mac based machine, you can use one of the cloud based workspace.

Cloud Workspace: Google Cloud Shell

Google Cloud provides a very good browser based shell. It is free to use. You will need a Google account to access cloudshell. Just go to Google Cloud Console - Cloudshell and follow the instructions to start cloud shell.

Ones you are in the shell, follow instruction in the Linux based host section of this page to finish setup.

Cloud Workspace: CodeAnywhere

CodeAnywhere provides an excellent web based IDE with terminal. This should sufficient for our usage. Just go through the signup process. You will need to verify you email in order to start using the workspace.

Signup using you email, github or any other social account
Verify you email
Create a workspace and call it pfs
Run the setup commands in the Linux based host section to finish setting

Linux based host

Setup kubectl (skip for GCP cloudshell)

curl -sLO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
chmod a+x kubectl
sudo mv kubectl /usr/local/bin
kubectl completion bash | sudo tee /etc/bash_completion.d/kubectl > /dev/null

OR on Mac

curl -sLO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl
chmod a+x kubectl
sudo mv kubectl /usr/local/bin

Setup pfs

curl -sLO https://github.com/yogendra/pfs-workshop/raw/master/setup-environment/bin/pfs.linux
chmod a+x pfs.linux
sudo mv pfs.linux /usr/local/bin/pfs
pfs completion bash | sudo tee /etc/bash_completion.d/pfs > /dev/null

OR on Mac

curl -sLO https://github.com/yogendra/pfs-workshop/raw/master/setup-environment/bin/pfs.darwin
chmod a+x pfs.darwin
sudo mv pfs.linux /usr/local/bin/pfs

Fetch Kuberentes config for workshop.

# Change this to you own user id given by the instructor
export WS_USER=CHANGE_ME

Following lines can be copy pasted

mkdir -p $HOME/.kube
[[ -e $HOME/.kube/config ]] && cp $HOME/.kube/config $HOME/.kube/config.original
curl -sL https://github.com/yogendra/pfs-workshop/raw/master/setup-environment/users/$WS_USER/config -o $HOME/.kube/config

TIP: Use Cheatsheet for setting up your shell now or later at any point

Test Workspace Setup

To check that you environment is configured properly, you may run following commands.

> kubectl cluster-info
Kubernetes master is running at https://pfs-workshop-k8s.atwater.cf-app.com:8443
CoreDNS is running at https://pfs-workshop-k8s.atwater.cf-app.com:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

> pfs service list
