To use

Install your public key into stack's authorized_keys

# ssh-copy-id stack@<undercloud-ip>

Then run gen_hosts.sh script to generate your overcloud's hosts file for ansible and generate a "jumpbox" ssh config:

# ./gen_hostfile.sh <undercloud-ip> ~/.ssh/config

**Review the hosts file the script generates.

Ansible Installers:

Install Browbeat

# ansible-playbook -i hosts install/browbeat.yml

Adjust your overcloud:

To modify the number of workers each service is running:

Nova and Keystone will be running 8 workers per service.

# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=eventlet"

To run Keystone in httpd, change keystone_deployment to httpd:

# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=httpd"

To switch to fernet tokens:

# ansible-playbook -i hosts browbeat/keystone_token_type.yml -e "token_provider=fernet"

To switch to UUID tokens:

# ansible-playbook -i hosts browbeat/keystone_token_type.yml -e "token_provider=uuid"
