Manage complexity
Charts can describe
complex apps; provide
repeatable app installs, and
serve as a single point of
authority
Easy updates
Take the pain out
of updates with in-
place upgrades and
custom hooks
Simple sharing
Charts are easy to
version, share, and host
on public or private
servers
Rollbacks
Use helm rollback to
roll back to an older
version of a release
with ease

built for Kubernetes](https://image.slidesharecdn.com/devopsk8sandhelmmeetup-190822181832/85/DevOps-Kuberenetes-Helm-and-Draft-Azure-Montevideo-Meetup-27-320.jpg)

Using two simple commands,
developers can now begin
hacking on container-based

Docker or even installing

Language support

your app is written in, and then

Dockerfile and Helm Chart with
the best practices for that

Editor's Notes
- #22: Kubernetes is a series of reconciliation loops that are constantly trying to reconcile the actual state toward the desired state specified by the declarative API
- #24: Kubernetes has a series of control plane components that run on the agents and the master nodes Kubelet – Responsible for pulling, running and monitoring images scheduled to it Container Runtime – Docker, application that actually runs the container (called by kubelet) Kube-Proxy – This makes service object real and routable by containers in the cluster Etcd – Distributed database that stores all the Kubernetes data and leverages extensively by the control plane to monitor and save state API Server – All components of the control plane, and tooling ran (kubectl) communicate with the API Server. Which fetches or writes the data to etcd. Controller Manager – Runs many reconciliation loops to ensure that API objects are reconciled (ReplicationController, Node Status, etc) Cloud Controller Manager – Reconciles API objects with a cloud provider (Service types of Load Balancer, Storage, etc)
