Currently we support Ansible 1.9.4 within browbeat-venv and Ansible 2.0+ for installation.
- Playbooks for:
- Installing Browbeat, collectd, 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
Install your public key into stack's authorized_keys
# ssh-copy-id stack@<undercloud-ip>
Then run generate_tripleo_hosts.sh script to generate your overcloud's hosts file for ansible and generate a "jumpbox" ssh config:
# ./generate_tripleo_hostfile.sh <undercloud-ip> ~/.ssh/config
Review the hosts file the script generates.
Image upload requires Ansible 2.0
# vi install/group_vars/all.yml
Edit ansible vars file (Installation parameters)
# ansible-playbook -i hosts install/browbeat.yml
Prior to installing the agent, please review install/group_vars/all.yml file 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.
Prior to installing the Kibana visuals, please review install/group_vars/all.yml file to ensure the correct parameters are passed.
- ::
- browbeat_path - Point to the browbeat directory, default is /home/stack/browbeat es_ip - Point to the ElasticSerach host, default is blank es_kibana_index - Point to the correct Kibana index, default is .kibana
To Install Kibana Visuals
# ansible-playbook -i hosts install/kibana-visuals.yml
Listening ports and other options can be changed in install/group_vars/all.yml
as needed. You can also change the logging backend to use fluentd via the
logging_backend: variable. For most uses leaving the defaults in place is
accceptable. If left unchanged the default is to use logstash.
You can also install the optional curator tool for managing
elasticsearch indexes. Set install_curator_tool: true to enable this optional tool installation.
If all the variables look ok in install/group_vars/all.yml you can proceed with deployment.
ansible-playbook -i hosts install/elk.yml
Triple-O based OpenStack deployments have a lot of ports already listening on the Undercloud node. You'll need to change the default listening ports for ELK to be deployed without conflict.
sed -i 's/nginx_kibana_port: 80/nginx_kibana_port: 8888/' install/group_vars/all.yml sed -i 's/elk_server_ssl_cert_port: 8080/elk_server_ssl_cert_port: 9999/' install/group_vars/all.yml
Now you can proceed with deployment.
ansible-playbook -i hosts install/elk.yml
Filebeat (official Logstash forwarder) is used here unless you chose the
optional fluentd logging_backend option in install/group_vars/all.yml. In this case
a simple rsyslog setup will be implemented.
ansible-playbook -i hosts install/elk-client.yml --extra-vars 'elk_server=X.X.X.X'
The elk_server variable will be generated after the ELK stack playbook runs,
but it's generally wherever you installed ELK. If you have an existing ELK
stack you can point new clients to it as well, but you'll want to place a new
client SSL certificate at the location of
http://{{elk_server}}:{{elk_server_ssl_cert_port}}/filebeat-forwarder.crt
ansible-playbook -i hosts install/elk-openstack-client.yml --extra-vars 'elk_server=X.X.X.X'
When installing graphite, carbon-cache and grafana on a director/rdo-manager undecloud host, Use the docker playbook instead of this one. This playbook is intended for use when you have enough resources to allocate dedicated systems for the graphing/stats related services. Prior to installing grafana, please review install/group_vars/all.yml file and your ansible inventory file You will need to define values for the grafana_host and graphite_host IP addresses here. Optionally you can change the listening port for graphite-web.
# ansible-playbook -i hosts install/graphite.yml
Prior to installing graphite as a docker container, please review install/group_vars/all.yml file and ensure the docker related settings will work with your target host. This playbook is ideal when installing services on director/rdo-manager undercloud host(s).
# ansible-playbook -i hosts install/graphite-docker.yml

# ansible-playbook -i hosts install/grafana-docker.yml
Review install/group_vars/all.yml before deploying the grafana dashboards
# ansible-playbook -i hosts install/dashboards-openstack.yml
Run the gather playbook to gather metadata about how the OpenStack cloud is currently configured. This playbook writes hardware(No. of CPUs etc), software(OpenStack Configuration), environment(No. of controllers etc) metadata files into the metadata directory which are transported to ElasticSearch along with test results to provide context for the result data.
# ansible-playbook -i hosts gather/site.yml
Run the check playbook to identify common performance issues:
# ansible-playbook -i hosts check/site.yml
Run the tune playbook to tune your OSPd deployed cloud for performance:
# ansible-playbook -i hosts tune/tune.yml
To modify the number of workers each service is running:
# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8"
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"
