Configurable Parameters in Kubespray
Generic Ansible variables
You can view facts gathered by Ansible automatically here.
Some variables of note include:
- ansible_user: user to connect to via SSH
-
ansible_default_ipv4.address: IP address Ansible automatically chooses.
Generated based on the output from the command
ip -4 route get 8.8.8.8
Common vars that are used in Kubespray
- calico_version - Specify version of Calico to use
- calico_cni_version - Specify version of Calico CNI plugin to use
- docker_version - Specify version of Docker to used (should be quoted string)
- etcd_version - Specify version of ETCD to use
- ipip - Enables Calico ipip encapsulation by default
- hyperkube_image_repo - Specify the Docker repository where Hyperkube resides
- hyperkube_image_tag - Specify the Docker tag where Hyperkube resides
- kube_network_plugin - Sets k8s network plugin (default Calico)
- kube_proxy_mode - Changes k8s proxy mode to iptables mode
- kube_version - Specify a given Kubernetes hyperkube version
- searchdomains - Array of DNS domains to search when looking up hostnames
- nameservers - Array of nameservers to use for DNS lookup
Addressing variables
- ip - IP to use for binding services (host var)
- access_ip - IP for other hosts to use to connect to. Often required when deploying from a cloud, such as OpenStack or GCE and you have separate public/floating and private IPs.
- ansible_default_ipv4.address - Not Kubespray-specific, but it is used if ip and access_ip are undefined
- loadbalancer_apiserver - If defined, all hosts will connect to this address instead of localhost for kube-masters and kube-master[0] for kube-nodes. See more details in the HA guide.
-
loadbalancer_apiserver_localhost - makes all hosts to connect to
the apiserver internally load balanced endpoint. Mutual exclusive to the
loadbalancer_apiserver. See more details in the HA guide.
