Inventory File Template
The
host.ini
file contains the inventory used by the various OCCNE deployment containers
that will instantiate the OCCNE cluster.
Template example
The inventory is composed of multiple groups (indicated by bracketed
strings):
- local: OCCNE ansible use. Do not modify.
- occne: list of servers in the OCCNE cluster that will be installed by the os_install container.
- k8s-cluster: list of servers in the kubernetes cluster.
- kube-master: list of servers that will be provisioned as kubernetes master nodes by the k8s_install container.
- kube-node: list of servers that will be provisioned as kubernetes worker nodes by the k8s_install container.
- etcd: list of servers that will be provisioned as part of kubernetes etcd cluster by the k8s_install container.
- data_store: list of servers that will be host the VMs of the MySQL database cluster, os_install container will install kvm on them.
- occne:vars: list of occne environment variables. Values for variables are required. See below for description.
