Note: Chart Manager is a community driven project. LogicMonitor support will not assist in any issues related to Chart Manager.
Chart Manager is a tool for dynamically managing Helm releases via Kubernetes custom resource objects
- Install, Manage, and Delete Helm releases programmatically: Simplify the process of installing, updating, and deleting large numbers of Helm releases. Rather than managing all of your Helm releases out-of-band, Chart Manager provides the ability to define and maintain all of your releases programmatically and in-cluster.
- Dynamically install versioned Helm charts from public or private repositories: Chart Manager supports creating Helm releases from charts stored in the public stable repository as well as custom private repositories. Note: Support for repositories requiring authentication is not yet implemented
- Specify Helm value overrides: In order to provide as much flexibility as possible, Chart Manager also provides the ability to override default chart values just as you would at the command line using '--set'.
Chart Manager Overview
Chart Manager provides a custom controller and Kubernetes Custom Resource Definition designed to dynamically create, manage, and delete Helm releases. It was developed with the goal of simplifying the process required to install a large number of applications via Helm when a new cluster is created. Chart Manager also provides the ability to maintain a definitive list of application deployments required for a given cluster since all releases can now be defined and stored just like any other Kubernetes resource definition.
Chart Manager custom resource objects contain information defining a Helm
chart, Helm repository, and any optional value overrides. The Chart Manager
controller uses this information create a Helm release for the chart in the
namespace where the custom object was created. If the custom object changes,
e.g. a value override gets updated, the Chart Manager controller will attempt
to update the existing release, similar to using helm upgrade. If
the custom object is deleted, the controller will delete the release.
