Ansible for Browbeat

Currently we support Ansible 1.9.4 within browbeat-venv and ansible 2.0 for installation.

Playbooks for:

• Installing Browbeat, collectd, connmon, ELK stack and clients, graphite, grafana, and grafana dashboards
• Check overcloud for performance issues
• Tune overcloud for performance (Experimental)
• Adjust number of workers for cinder/keystone/neutron/nova
• Deploy keystone in eventlet/httpd
• Adjust keystone token type to UUID/Fernet
• Adjust neutron l3 agents
• Adjust nova greenlet_pool_size / max_overflow

Getting Started

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-playbook -i hosts install/grafana.yml

Install grafana service as a docker container

Adjust your overcloud

To modify the number of workers each service is running:

Openstack services will be running 8 workers per service.

To modify number of workers each service is running and ensure Keystone is deployed in eventlet:

# 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/adjustment-keystone-token.yml -e "token_provider=fernet"

To switch to UUID tokens:

# ansible-playbook -i hosts browbeat/adjustment-keystone-token.yml -e "token_provider=uuid"
