What is Helm?
Helm helps you manage Kubernetes applications — Helm Charts help you define, install, and upgrade even the most complex Kubernetes application.

Charts are easy to create, version, share, and publish — so start using Helm and stop the copy-and-paste.

The latest version of Helm is maintained by the CNCF - in collaboration with Microsoft, Google, Bitnami and the Helm contributor community.

 and third generation development is started at July 2018 Package manager for Kubernetes clusters
  3. 3. Copyright 2018 bee42 solutions gmbh <peter.rossbach@bee42.com> @PRossbach rethink IT - We improve your systems with passion What is Helm? 3 •Helm charts are build on top of Kubernetes manifests •Charts are stored in a registry called Helm Museum •It use a templating preprocessing and managed release of Kubernetes resources •Ability to consider scalability from the get-go •SRE’s and developer can search of charts and scratch it.
  4. 4. Copyright 2018 bee42 solutions gmbh <peter.rossbach@bee42.com> @PRossbach rethink IT - We improve your systems with passion 4 • Kubernetes is a container orchestrator. • It’s how to run containers at scale. • It’s a very active open-source platform with lots of contributors, start at 6.

Copyright 2018 bee42 solutions gmbh <peter.rossbach@bee42.com> @PRossbach rethink IT - We improve your systems with passion K8s Deployment Challenge 7 Move to microservice or serverless architecture. Applications consists from multiple components each component has its own resources and can be scaled individually. It’s hard to ... ... manage, edit and update multiple K8s configurations ... deploy multiple K8s configurations as a SINGLE application ... share and reuse K8s configurations and applications ... parametrize and support multiple environments ... manage application releases: rollout, rollback, diff, history ... define deployment lifecycle (control operations to be run in different phases) ... validate release state after deployment
