|
== Purpose
|
|
|
|
The Machine Config Operator manages and applies configuration and updates of the base operating system and container runtime, including everything between the kernel and kubelet.
|
|
|
|
There are four components:
|
|
|
|
* `machine-config-server`: Provides Ignition configuration to new machines joining the cluster.
|
|
* `machine-config-controller`: Coordinates the upgrade of machines to the desired configurations defined by a `MachineConfig` object. Options are provided to control the upgrade for sets of machines individually.
|
|
* `machine-config-daemon`: Applies new machine configuration during update. Validates and verifies the state of the machine to the requested machine configuration.
|
|
* `machine-config`: Provides a complete source of machine configuration at installation, first start up, and updates for a machine.
