DNS

---
|
|
|
|
The data in the ``dns`` key is used for bootstrapping and ``kubelet``
|
|
configuration of cluster and host-level DNS, which is provided by coredns_.
|
|
|
|
``bootstrap_validation_checks``
|
|
Domain names to resolve during the genesis and join processes for validation.
|
|
|
|
``cluster_domain``
|
|
The Kubernetes cluster domain. Used by the ``kubelet``.
|
|
|
|
``service_ip``
|
|
The IP to use for cluster DNS. Used by the ``kubelet``.
|
|
|
|
``upstream_servers``
|
|
Upstream DNS servers to be configured in `/etc/resolv.conf`.

Kubernetes
|
|
----------
|
|
|
|
The ``kubernetes`` key contains:
|
|
|
|
``apiserver_port``
|
|
The port that the Kubernetes API server process will listen on on hosts where it runs.
|
|
|
|
``haproxy_port``
|
|
The port that HAProxy will listen on on each host. This port will be used
|
|
by the ``kubelet`` and ``kube-proxy`` to find API servers in the cluster.
|
|
|
|
``pod_cidr``
|
|
The CIDR from which the Kubernetes Controller Manager assigns pod IPs.
|
|
|
|
``service_cidr``
|
|
The CIDR from which the Kubernetes Controller Manager assigns service IPs.
|
|
|
|
``service_ip``
|
|
The in-cluster Kubernetes service IP.
