# Deploying admin and user clusters

The playbook playbooks/create_cluster.yml will create admin and/or user clusters as specified in your configuration file.

Note: If you have already have a working admin cluster and want to add a user cluster, then set 'create_admin_cluster: false' before running playbook playbooks/create_cluster.yml.

# Prerequisites

# Command

cd ~/Anthos-on-SimpliVity

ansible-playbook playbooks/create_cluster.yml  --ask-vault-pass

# Monitoring GKE Cluster Creation

You can monitor the cluster creation logs using the script cluster-watch.py in the scripts directory. To execute the program:

  • Open a new terminal session on Ansible controller
  • Source the same python virtual environment as you did for Ansible
  • run cluster-watch.py

The script uses the Linux lnav program to tail the log files created during the GKE cluster creation.
