A HELM INTRODUCTION OR WHY EVERYONE SHOULD BE USING HELM
What the HELM !?

SELF INTRODUCTION
▸ My open thinking and open techniques
ideology is driven by Open Source
technologies and the collaborative manner
deﬁning my M.O.
▸ My solution driven approach is strongly based on hands-on
and deep understanding of Operating Systems,
Applications stacks and Software languages, Networking,
Cloud in general and today more an more Cloud Native
solutions.

INTRODUCTION TO HELM
OUR “COMPLICATED” MICRO SERVICE APPLICATION
/ -> GET "pings"
/ping -> SET "pings" + 1
/isAlive -> return “It's aaaalive!”
{ pings: Int }

OUR “COMPLICATED” MICRO SERVICE APPLICATION
Status Poller
/ -> GET "pings"
{ pings: Int }
curl -s -X POST “${API_URL}/ping”
curl -s "${API_URL}/"
read every 1 sec
Increment by 1 every 1 sec

OUR “COMPLICATED” MICRO SERVICE APPLICATION - DOCKERIZED
Status Poller
/ -> GET "pings"
{ pings: Int }
curl -s -X POST “${API_URL}/ping”
curl -s "${API_URL}/"
read every 1 sec
Increment by 1 every 1 sec

GET THE DEMO CODE
▸ https://github.com/shelleg/msa-demo-app

PLANNING OUR DEPLOYMENT
▸ Each micro service has a build
process which pushes the container
to a docker registry.
▸ Docker registry is available to the k8s
cluster during deployment (with or
without authentication depending on
the deployment)

DEPLOYMENT SEQUENCE

DEPLOYMENT SEQUENCE
‣ redis deployment + service for redis

DEPLOYMENT SEQUENCE
‣ msa-api deployment + service for the msa-api

DEPLOYMENT SEQUENCE
‣ msa-pinger deployment

DEPLOYMENT SEQUENCE
‣ msa-poller deployment

DEPLOYMENT SEQUENCE
‣ msa-poller deployment ‣ msa-demo namespace

DEPLOYMENT SEQUENCE
‣ persistent volume for redis data

DEPLOYMENT SEQUENCE
‣ persistent volume for redis data
‣ conﬁgmaps / secrets for all components

KUBERNETES “NATIVE” WAY
▸ Create a namespace: 
kubectl create namespace msa-demo --dry-run -o yaml > msa-demo-ns.yml
▸ Create a deployment + service for redis: 
kubectl run redis --image=redis --port=6379 --expose --dry-run -o yaml > redis.yml
▸ Create a deployment + service for msa-api: 
kubectl run msa-api --image=shelleg/msa-api:conﬁg --port=8080 —expose --image-pull-
policy=Always --dry-run -o yaml > msa-api.yml

KUBERNETES “NATIVE” WAY
▸ Create a deployment for msa-pinger: 
kubectl run msa-pinger --image=shelleg/msa-pinger:latest --env="API_URL=msa-api:
8080" --env="DEBUG=true" --dry-run -o yaml > msa-pinger.yml
▸ Create a deployment for msa-poller: 
kubectl run msa-poller --image=shelleg/msa-poller:latest --env="API_URL=msa-api:8080"
--dry-run -o yaml > msa-pinger.yml

HANDS ON

WE NOW HAVE A BUNCH OF FILES DESCRIBING OUR APPLICATION

SO WHY DO WE NEED HELM ?!
▸ We want to better control “what goes where” e.g ports
▸ Container image versions ?! (is the only change between releases)
▸ Manage Dependencies
▸ Update components individually updating things like image
versions e.g msa-api:latest -> msa-api:conﬁg
▸ Write once run on any cluster
▸ Reproducible & Shareable resource deﬁnition specs -
TEMPLATES

TEMPLATES
▸ Not a foreign concept … Jinja / erb / jsonnet
{% for key, svc in services.items() %}
upstream {{ key }} {
least_conn;
{% for server in svc.delegate %}
server {{ server }}:{{ svc.ports[0].split(':')[0] }} weight=10
max_fails=3 fail_timeout=30s;
{% endfor %}
}
{% endfor %}
// A function that returns an object.
local Person(name='Alice') = {
name: name,
welcome: 'Hello ' + name + '!',
};
{
person1: Person(),
person2: Person('Bob'),
}
<% @sudoers_users.each do |user| -%>
<%= user %> ALL=(ALL) <%= "NOPASSWD:" if @passwordless %>ALL
<% end -%>
# Members of the sysadmin group may gain root privileges
%sysadmin ALL=(ALL) <%= "NOPASSWD:" if @passwordless %>ALL

SO WHY DO WE NEED HELM ?!
▸ Kubernetes native discovery mechanism is focused around the Service /
deployment
▸ Helm Charts are Application focused

chaoskube is running and will kill arbitrary pods every

You can follow the logs to see what chaoskube does:
POD=$(kubectl -n {{ .Release.Namespace }} get pods -
l='release={{ template "chaoskube.fullname" . }}' --
output=jsonpath='{.items[0].metadata.name}
')
kubectl -n {{ .Release.Namespace }} logs -f $POD
{{ if .Values.dryRun }}
You are running in dry-run mode. No pod is actually terminated.

HOW TO USE THIS LAB ?!

FullStack Developers IL
KUBERNETES 101 | GETTING STARTED
MINIKUBE
▸ Minikube supports Kubernetes features such as:
▸ DNS
▸ NodePorts
▸ ConﬁgMaps and Secrets
▸ Dashboards
▸ Container Runtime: Docker, rkt and CRI-O
▸ Enabling CNI (Container Network Interface)
▸ Ingress

WHY
▸ Good for POC, QuickStarts and Demo’s
▸ Gives a taste of Kubernetes and how to work with it, without going through a
complex setup

INSTALLING MINIKUBE
▸ Install kubectl link
▸ Install minikube link

MINIKUBE START
▸ minikube start
▸ 20:31 $ minikube start
Starting local Kubernetes v1.9.0 cluster...
Starting VM...
Getting VM IP address...
Moving files into cluster...
Setting up certs...
Connecting to cluster...
Setting up kubeconfig...
Starting cluster components...
Kubectl is now configured to use the cluster.
Loading cached images from config file.

CONFIGURE HELM REPOSITORIES
helm repo add stable https://kubernetes-charts.storage.googleapis.com

INSTALL HELM-S3 PLUGIN
helm plugin install https://github.com/hypnoglow/helm-s3.git
-> If you are planning on pushing to your s3 based helm repo
-> get your own repo and setup the required permissions.
-> I our case you will be using it for read / download purposes which is already public / open source.

ADD THE MSA-CHARTS S3 HELM REPOSITORY
helm repo add msa-charts s3://msa-charts/
s3 plugin updates
the index.yaml on
each version
updload

DEPLOY YOUR UMBRELLA …
kubectl create namespace msa-umbrella
helm dep build ./helm/msa-umbrella
helm install --name v1 --namespace msa-umbrella ./helm/msa-umbrella

CHECK YOUR UMBRELLA …
helm list # view helm releases which are installed
kubectl -n msa-umbrella get po,svc,deploy # view msa-umbrella pods, services & deployments

RECAP
▸ Helm is awesome -> ( completes Kubernetes )
▸ Application centric solution
▸ Flexible templating language
▸ Well integrated into workﬂows such as GitKube, Scafold and others

USE [ DON’T OVER USE ] YOUR IMAGINATION
▸ Custom Resource Definitions { e.g istio }
▸ Common monitoring RD’s { e.g prometheus }
▸ Common logging RD’s { e.g fluentd }
▸ Ingresses (yes / no)
▸ Services (type: NodePort, ClusterIp, LoadBalancer)
▸ Provider specific configs { on-prem vs. cloud }
▸
| {{ if .Values.monitoring.enabled }}
| {{ if .Values.logging.enabled }}
| {{ if .Values.service.nodeIp }}

So Whats Next ? …

kubectl create
