ManagedOSVersionChannel reference
The ManagedOSVersionChannel resource is responsible of defining OS image channels which embed
information about ready to use OS and ISO images.
The ManagedOSVersionChannel is digested by the elemental-operator
to produce a set of ManagedOSVersion resources, which are used
for building installation images and to perform OS upgrades.
See Operator/Channels for more details.
There are several keys that can be configured under a ManagedOSVersionChannel resource spec.

ManagedOSVersionChannelSpec reference​
| Key | Type | Default value | Description |
|---|---|---|---|
| deleteNoLongerInSyncVersions | bool | false | Automatically delete deprecated OS versions that are no longer included in the channel |
| enabled | bool | true | Enables this channel. Allowing syncing of OS versions. |
| options | object | null | Defines the optional informations that can be added in an OS channel |
| registry | string | empty | Registry prepended to all the embedded URIs during ManagedOSVersion resource generation |
| syncInterval | string | 1h | Defines when to sync the OS channel |
| type | string | empty | Defines the channel type, only custom is supported now |
| upgradeContainer | object | null | An upgrade container that can be defined. See reference |
registry​
When set, the value is prepended to all the embedded OS and ISO URLs found in the channel to form the actual ManagedOSVersion resources. This makes the airgap setup easier, as the channel image can be used as is (while the actual OS and ISO images should still be extracted and loaded on the private registry).
upgradeContainer​
This allows to overwrite the default upgrade field of System Upgrade Controller plans (see upgrade compontents) based on this ManagedOSVersion.
These keys are translated by the System Upgrade Controller to a Kubernetes container specification.
This is the container responsible of running an OS upgrade.
