Chapter 7. MachineConfigPool [machineconfiguration.openshift.io/v1] Description MachineConfigPool describes a pool of MachineConfigs. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required spec 7.1. Specification Property Type Description apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object MachineConfigPoolSpec is the spec for MachineConfigPool resource. status object MachineConfigPoolStatus is the status for MachineConfigPool resource. 7.1.1. .spec Description MachineConfigPoolSpec is the spec for MachineConfigPool resource. Type object Property Type Description configuration object The targeted MachineConfig object for the machine config pool. machineConfigSelector object machineConfigSelector specifies a label selector for MachineConfigs. Refer https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/ on how label and selectors work. maxUnavailable integer-or-string maxUnavailable defines either an integer number or percentage of nodes in the pool that can go Unavailable during an update. This includes nodes Unavailable for any reason, including user initiated cordons, failing nodes, etc. The default value is 1. A value larger than 1 will mean multiple nodes going unavailable during the update, which may affect your workload stress on the remaining nodes. You cannot set this value to 0 to stop updates (it will default back to 1); to stop updates, use the 'paused' property instead. Drain will respect Pod Disruption Budgets (PDBs) such as etcd quorum guards, even if maxUnavailable is greater than one. nodeSelector object nodeSelector specifies a label selector for Machines paused boolean paused specifies whether or not changes to this machine config pool should be stopped. This includes generating new desiredMachineConfig and update of machines. 7.1.2. .spec.configuration Description The targeted MachineConfig object for the machine config pool. Type object Property Type Description apiVersion string API version of the referent. fieldPath string If referring to a piece of an object instead of an entire object, this string should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2]. For example, if the object reference is to a container within a pod, this would take on a value like: "spec.containers{name}" (where "name" refers to the name of the container that triggered the event) or if no container name is specified "spec.containers[2]" (container with index 2 in this pod). This syntax is chosen only to have some well-defined way of referencing a part of an object. kind string Kind of the referent.
