Neutron/LBaaS/DeployWithDevstack

Deploying Neutron LBaaS With Devstack

• Install devstack with neutron and neutron lbaas
  • If you don't have devstack installed you can follow the instructions on this link. It will enable the v1 lbaas API
  • http://roaet.com/my-method-to-installuse-devstack
• Code with LoggingNooopDriver is merged. No review needed to pull down.
  • Synchronous Haproxy Driver (Contains LoggingNoopDriver as well)
    • https://review.openstack.org/#/c/144832/
• Run database migration
  • neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head
  • If any issues pop up its probably better to just ./unstack.sh devstack and ./stack.sh devstack again while you've got the gerrit change request checked out.
• Change the neutron config
  • /etc/neutron/neutron.conf
    • Under the [DEFAULT] section there is an options called service_plugins. It is a comma-delimited list. Add the following to it:
      • If service_plugins option already exists add to the end of the line:
        • ,neutron.services.loadbalancer.plugin.LoadBalancerPluginv2
      • If service_plugins option does not exist add this line:
        • service_plugins = neutron.services.loadbalancer.plugin.LoadBalancerPluginv2
    • Under the [service_providers] section (usually at the bottom) there are options called service_provider, there can be many service_provider entries. Add the following
      • To use the LoggingNoopDriver:
        • service_provider=LOADBALANCERV2:LoggingNoop:neutron.services.loadbalancer.drivers.logging_noop.driver.LoggingNoopLoadBalancerDriver:default
      • To use the Synchronous Haproxy Driver:
        • Uncomment the line that looks like the line below
        • service_provider=LOADBALANCERV2:Haproxy:neutron.services.loadbalancer.drivers.haproxy.synchronous_namespace_driver.HaproxyNSDriver:default
• Re-install the neutron code and restart the neutron-server process. This is most easily done by going into the devstack screen, switching to neutron server (^A-6, the screen name is q-svc), hitting ^C, up arrow, enter. Alternately:
  • I use this bash script:

#!/bin/bash

if [ `ps aux | grep neutron-server | wc -l` -gt 1 ]; then
    kill -9 `ps aux | grep '[n]eutron-server' -m1 | awk '{print $2}'`
fi

sudo pip install --build=/tmp/pip-build.bE71P -e /opt/stack/neutron

/usr/local/bin/neutron-server --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini

• Install the CLI/client

cd /opt/stack/python-neutronclient
git review -d 111475
sudo python setup.py install

• Create Entities Using CLI/client

  •  neutron lbaas-pool-create --lb-algorithm ROUND_ROBIN --protocol HTTP pool1 

  •  neutron lbaas-member-create --subnet-id $(neutron subnet-list | awk '/ private-subnet / {print $2}') --address 10.0.0.2 --protocol-port 80 $(neutron lbaas-pool-list | awk '/ pool1 / {print $2}') 

  •  neutron lbaas-loadbalancer-create lb1 $(neutron subnet-list | awk '/ private-subnet / {print $2}') 

  •  neutron lbaas-listener-create --loadbalancer-id $(neutron lbaas-loadbalancer-list | awk '/ lb1 / {print $2}') --protocol HTTP --protocol-port 80 --default-pool-id $(neutron lbaas-pool-list | awk '/ pool1 / {print $2}') 

• Command-line tester

A mostly stand-alone test script that drives the CLI and API to create load balancers in various configurations: https://github.com/dougwig/lbaas_tester

• Issues
  • If you get an error similar to "operational error" with some DB fluff, you'll need to stop neutron, run migrations, and restart neutron. If the migration fails, you might need to clean out stale lbaas tables by hand and try again. https://github.com/openstack/neutron/blob/master/neutron/db/migration/README
• DEMO system
  • For reviewers only, /msg an ssh public key to dougwig

  • ssh ubuntu@v2.lbaas.me

  • Source the files "admin-openrc.sh" or "demo-openrc.sh" as needed (should be almost all demo-openrc.sh)
  • For Horizon, use admin/secretadmin or demo/secretadmin
  • This is a standard devstackgate box; logs will be in /opt/stack/new/screen-logs. Please do NOT re-run stack.sh.
