Overview ¶
Package v1alpha3 defines the v1alpha3 version of the kubeadm config file format, that is a big step forward the objective of graduate kubeadm config to beta.
One of the biggest changes introduced by this release is the re-design of how component config can be provided to kubeadm; this will enable a improved stability of the kubeadm config while the efforts for the implementation of component config across Kubernetes ecosystem continues.
Another important change is the separation between cluster wide setting and runtime or node specific settings, that is functional to the objective to introduce support for HA clusters in kubeadm.
Migration from old kubeadm config versions ¶
Please convert your v1alpha2 configuration files to v1alpha3 using the kubeadm config migrate command of kubeadm v1.12.x (conversion from older releases of kubeadm config files requires older release of kubeadm as well e.g.
kubeadm v1.11 should be used to migrate v1alpha1 to v1alpha2).
Nevertheless, kubeadm v1.12.x will support reading from v1alpha2 version of the kubeadm config file format, but this support will be dropped in the v1.13 release.
Basics ¶
The preferred way to configure kubeadm is to pass an YAML configuration file with the --config option. Some of the configuration options defined in the kubeadm config file are also available as command line flags, but only the most common/simple use case are supported with this approach.
A kubeadm config file could contain multiple configuration types separated using three dashes (“---”).
The kubeadm config print-defaults command print the default values for all the kubeadm supported configuration types.
apiVersion: kubeadm.k8s.io/v1alpha3 kind: InitConfiguration ... --- apiVersion: kubeadm.k8s.io/v1alpha3 kind: ClusterConfiguration ... --- apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration ... --- apiVersion: kubeproxy.config.k8s.io/v1alpha1 kind: KubeProxyConfiguration ... --- apiVersion: kubeadm.k8s.io/v1alpha3 kind: JoinConfiguration ...
The list of configuration types that must be included in a configuration file depends by the action you are performing (init or join) and by the configuration options you are going to use (defaults or advanced customization).
If some configuration types are not provided, or provided only partially, kubeadm will use default values; defaults provided by kubeadm includes also enforcing consistency of values across components when required (e.g. cluster-cidr flag on controller manager and clusterCIDR on kube-proxy).
Users are always allowed to override default values, with the only exception of a small subset of setting with relevance for security (e.g. enforce authorization-mode Node and RBAC on api server)
Starting from v1.12.1, if the user provides a configuration types that is not expected for the action you are performing, kubeadm will ignore those types and print a warning.
Kubeadm init configuration types ¶
When executing kubeadm init with the --config option, the following configuration types could be used: InitConfiguration, ClusterConfiguration, KubeProxyConfiguration, KubeletConfiguration, but only one between InitConfiguration and ClusterConfiguration is mandatory.
apiVersion: kubeadm.k8s.io/v1alpha3 kind: InitConfiguration bootstrapTokens: ... nodeRegistration: ... apiEndpoint: ...
InitConfiguration (and as well ClusterConfiguration afterwards) are originated from the MasterConfiguration type in the v1alpha2 kubeadm config version.
- The InitConfiguration type should be used to configure runtime settings, that in case of kubeadm init are the configuration of the bootstrap token and all the setting which are specific to the node where kubeadm is executed, including:
- NodeRegistration, that holds fields that relate to registering the new node to the cluster; use it to customize the node name, the CRI socket to use or any other settings that should apply to this node only (e.g. the node ip).
- APIEndpoint, that represents the endpoint of the instance of the API server to be deployed on this node; use it e.g. to customize the API server advertise address.
apiVersion: kubeadm.k8s.io/v1alpha3 kind: ClusterConfiguration networking: ... etcd: ... apiServerExtraArgs: ... APIServerExtraVolumes: ... ...
The ClusterConfiguration type should be used to configure cluster-wide settings, including settings for:
- Networking, that holds configuration for the networking topology of the cluster; use it e.g. to customize node subnet or services subnet.
- Etcd configurations; use it e.g. to customize the local etcd or to configure the API server for using an external etcd cluster.
- kube-apiserver, kube-scheduler, kube-controller-manager configurations; use it to customize control-plane components by adding customized setting or overriding kubeadm default settings.
apiVersion: kubeproxy.config.k8s.io/v1alpha1 kind: KubeProxyConfiguration ...
The KubeProxyConfiguration type should be used to change the configuration passed to kube-proxy instances deployed in the cluster. If this object is not provided or provided only partially, kubeadm applies defaults.
See https://kubernetes.io/docs/reference/command-line-tools-reference/kube-proxy/ or https://godoc.org/k8s.io/kube-proxy/config/v1alpha1#KubeProxyConfiguration for kube proxy official documentation.
apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration ...
The KubeletConfiguration type should be used to change the configurations that will be passed to all kubelet instances deployed in the cluster. If this object is not provided or provided only partially, kubeadm applies defaults.
See https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet/ or https://godoc.org/k8s.io/kubelet/config/v1beta1#KubeletConfiguration for kube proxy official documentation.
Here is a fully populated example of a single YAML file containing multiple configuration types to be used during a `kubeadm init` run.

Kubeadm join configuration types ¶
When executing kubeadm join with the --config option, the JoinConfiguration type should be provided.
apiVersion: kubeadm.k8s.io/v1alpha3 kind: JoinConfiguration ...
JoinConfiguration is originated from NodeConfiguration type in the v1alpha2 kubeadm config version.
The JoinConfiguration type should be used to configure runtime settings, that in case of kubeadm join are the discovery method used for accessing the cluster info and all the setting which are specific to the node where kubeadm is executed, including:
- NodeRegistration, that holds fields that relate to registering the new node to the cluster; use it to customize the node name, the CRI socket to use or any other settings that should apply to this node only (e.g. the node ip).
- APIEndpoint, that represents the endpoint of the instance of the API server to be eventually deployed on this node.
