  •  armhf

System requirements

Deployment environment must have Ansible 2.4.0+ Master and nodes must have passwordless SSH access

Second, edit inventory/my-cluster/hosts.ini to match the system information gathered above. For example:




If needed, you can also edit inventory/my-cluster/group_vars/all.yml to match your environment.

Start provisioning of the cluster using the following command:

ansible-playbook site.yml -i inventory/my-cluster/hosts.ini
