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 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.

Ansible Installers

Install Browbeat

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

Install Collectd Agent (Requires a Graphite Server)

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.

Install Connmon

Requires Ansible 2.0

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

Install Generic ELK Stack

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.

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

Install ELK Stack (on an OpenStack Undercloud)

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

Install Generic ELK Clients

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

Install ELK Clients for OpenStack nodes

ansible-playbook -i hosts install/elk-openstack-client.yml --extra-vars 'elk_server=X.X.X.X'

Install graphite service

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.

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

Install graphite service as a docker container

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

Install grafana service

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.

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

Install grafana service as a docker container

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/grafana-docker.yml

Install Grafana Dashboards (Requires a Grafana Server)

Review install/group_vars/all.yml before deploying the grafana
dashboards

# ansible-playbook -i hosts install/dashboards-openstack.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"

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"
