Use Helm charts

Helm is a tool that manages Kubernetes packages called charts, which are put to use in defining, installing, and upgrading Kubernetes applications. These charts, in conjunction with Helm tooling, deploy applications into Kubernetes clusters. Charts are comprised of a collection of files and directories, arranged in a particular structure and packaged as a .tgz file. Charts define Kubernetes objects, such as the Service and DaemonSet objects used in the application under deployment.

MSR enables you to use Helm to store and serve Helm charts, thus allowing users to push charts to and pull charts from MSR repositories using the Helm CLI and the MSR API.

Note

To obtain the CA certificate required by the Helm charts commands, navigate to https://<msr-url>/ca and download the certificate, or run:

curl -sk https://<msr-url>/ca > ca.crt
