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, 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
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
Image upload requires Ansible 2.0
# vi install/group_vars/all # Edit ansible vars file (Installation parameters)
# ansible-playbook -i hosts install/browbeat.yml
Install Collectd Agent (Requires a Graphite Server)
Prior to installing the agent, please review the install/group_vars/all to ensure the correct parameters are passed
# ansible-playbook -i hosts install/collectd-openstack.yml
To install collectd on everything other than Openstack machines, view the README for collectd-generic.
Install Connmon
Requires Ansible 2.0
# ansible-playbook -i hosts install/connmon.yml
Install graphite service
# ansible-playbook -i hosts install/graphite.yml
Install grafana service
Default user is admin/admin and the graphite data source will need to be defined.
# ansible-playbook -i hosts install/grafana.yml
Install Grafana Dashboards (Requires a Grafana Server)
Review install/group_vars/all before deploying the grafana dashboards
# ansible-playbook -i hosts install/dashboards.yml
Performance Check
Run the check playbook to identify common performance issues:
# ansible-playbook -i hosts check/site.yml
Performance Tune
Run the tune playbook to tune your OSPd deployed cloud for performance:
# ansible-playbook -i hosts tune/tune.yml
Adjust your overcloud
To modify the number of workers each service is running:
# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8"
Nova and Keystone 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/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"
