What is Helm?
Helm
Helm is maintained by the CNCF - in collaboration
with Microsoft, Google, Bitnami and the Helm contributor community.
Helm started as a Kubernetes project, but graduated to be a standalone
CNCF project in the incubating stage.
Incubating stage is the middle tier of CNCF
Helm
Specific for Helm 2:
Helm has two parts: a client (helm) and a server (tiller)
Tiller runs inside of your Kubernetes cluster, and manages releases
(installations) of your charts.
Helm 3 – “everything” will change :D (client only architecture)
Charts
Think of it like the Kubernetes equivalent of a Homebrew formula, an
Aptitude package, or a Yum RPM file.
Charts are Helm packages that contain at least two things:
A description of the package (Chart.yaml)
One or more templates, which contain Kubernetes manifest files (yaml files
contains templates, when rendered becomes a proper object)
Charts can be stored on disk, or fetched from remote chart
repositories.
Helm.sh tells:
So, in a nutshell:
Helm makes
your life easier!
Who here likes
writing
dockerfiles?
Why not let the
machines do it?

Time for a
demo!
Demo: Easily
deploy complex
application
(wordpress) to
Kubernetes using
a helm chart
Installing Helm:
What do you
need?
Installing Helm
Package manager:
- Homebrew
- Snap
- Chocolatey
Manual installs:
- Download binaries from Githutb
So, then?
After downloading run “helm init” to initialize Helm client and Tiller to
your running Kubernetes cluster. It will also set up any necessary local
configuration.
Note that you need to have an a running Kubernetes cluster and
Kubectl set up. Depending on your setup, permission changes for your
Kubernetes installation might be needed.
Success!
Helm commands
First Helm commands:
helm search: search for charts
helm fetch: download a chart to your local directory to
view
helm install: upload the chart to Kubernetes
helm list: list releases of charts
Tada! Neat,
wasn’t it!
Thank you!
