## Helm Charts in Rancher
|

## How Helm Charts Work in Rancher
|
||||
|
||||
Rancher uses a catalog-like system to import bundles of charts from repositories and then uses those charts to either deploy custom Helm applications or Rancher's tools such as Monitoring or Istio. Rancher tools come as pre-loaded repositories which deploy as standalone Helm charts. Any additional repositories are only added to the current cluster.

|

|
||||
### Changes in Rancher v2.6
|
||||
### Catalogs, Apps, and the Rancher UI
|
||||
|
||||
Starting in Rancher v2.6.0, a new versioning scheme for Rancher feature charts was implemented. The changes are centered around the major version of the charts and the +up annotation for upstream charts, where applicable.
|
||||
[Rancher v2.4 and earlier](/versioned_docs/version-2.0-2.4/how-to-guides/new-user-guides/helm-charts-in-rancher/helm-charts-in-rancher.md), repositories of ready-to-deploy applications were called "catalogs". These repositories were managed through the **Catalogs** section of the UI.
|
||||
|
||||
**Major Version:** The major version of the charts is tied to Rancher minor versions. When you upgrade to a new Rancher minor version, you should ensure that all of your **Apps & Marketplace** (Rancher before v2.6.5) or **Apps** (Rancher v2.6.5+) charts are also upgraded to the correct release line for the chart.
|
||||
Helm chart repositories are now managed using **Apps & Marketplace** (before Rancher v2.6.5) or **Apps** (Rancher v2.6.5 and later).
|
||||
|
||||
### Versioning Changes in Rancher v2.6
|
||||
|
||||
Starting in Rancher v2.6.0, a new versioning scheme for Rancher feature charts was implemented. The changes are centered around the major version of the charts and the `+up` annotation for upstream charts, where applicable.
|
||||
|
||||
**Major Version:** The major versions of feature charts are tied to Rancher minor versions. When you upgrade to a new Rancher minor version, you should ensure that all of your charts are also upgraded to the correct release line for the chart.
|
||||
|
||||
**Charts based on upstream:** When you upgrade, make sure that the upstream chart version is compatible with your Rancher version. The `+up` annotation for the chart indicates which upstream version the Rancher chart is tracking. For example, `100.x.x+up16.6.0` for Monitoring tracks upstream kube-prometheus-stack `16.6.0` with some additional Rancher patches.
|
||||
|
||||
When upgrading Rancher versions, don't downgrade the version of the chart that you are using. For example, if you are using a version of Monitoring that is later than `16.6.0` in Rancher v2.5, you shouldn't upgrade to `100.x.x+up16.6.0`. Instead, you should upgrade to the appropriate version in the next release.

**Charts based on upstream:** For charts that are based on upstreams, the +up annotation should inform you of what upstream version the Rancher chart is tracking. Check the upstream version compatibility with Rancher during upgrades also.
|

|
||||
- As an example, `100.x.x+up16.6.0` for Monitoring tracks upstream kube-prometheus-stack `16.6.0` with some Rancher patches added to it.
|
||||
|
||||
- On upgrades, ensure that you are not downgrading the version of the chart that you are using. For example, if you are using a version of Monitoring > `16.6.0` in Rancher 2.5, you should not upgrade to `100.x.x+up16.6.0`. Instead, you should upgrade to the appropriate version in the next release.
