The History of the Project
Kubernetes Helm is the merged result of HelmClassic and the Kubernetes port of GCS DeploymentManager. The project was jointly started by Google and Deis, though itis now part of the CNCF. Many companies now contribute regularly to Helm.
Differences from Helm Classic:
- Helm now has both a client (
helm
) and a server (tiller
). Theserver runs inside of Kubernetes, and manages your resources. - Helm's chart format has changed for the better:
- Dependencies are immutable and stored inside of a chart's
charts/
directory. - Charts are strongly versioned using SemVer 2
- Charts can be loaded from directories or from chart archive files
- Helm supports Go templates without requiring you to run
generate
ortemplate
commands. - Helm makes it easy to configure your releases — and share theconfiguration with the rest of your team.
- Dependencies are immutable and stored inside of a chart's
- Helm chart repositories now use plain HTTP(S) instead of Git/GitHub.There is no longer any GitHub dependency.
- A chart server is a simple HTTP server
- Charts are referenced by version
- The
helm serve
command will run a local chart server, though youcan easily use object storage (S3, GCS) or a regular web server. - And you can still load charts from a local directory.
- The Helm workspace is gone. You can now work anywhere on yourfilesystem that you want to work.
