It contains Vagrantfile and chef recipes to deploy three VMs including OpenStack and Masakari. You will be able to test and demonstrate the way how Masakari works on your laptop.

• vagrant

• vagrant box of ubuntu/trusty64 (or centos/7 for cent OS)

  For Ubuntu,

  $ vagrant box add ubuntu/trusty64

  For CentOS,

  $ vagrant box add centos/7

• creating three VMs consisting of Controller, Compute1 and Compute2.

  Default Vagrant file use the ubuntu/trusty64 box.

  Change config.vm.box = "centos/7" to build masakari with centOS.

  To successfully build centos environment, you might need to install vagrant-vbguest plugin

  $ vagrant plugin install vagrant-vbguest

  $ vagrant up
  $ vagrant status
  Current machine states:
  
  controller                running (virtualbox)
  compute1                  running (virtualbox)
  compute2                  running (virtualbox)

• deploy OpenStack in Controller

  $ vagrant ssh controller
  vagrant@controller:~$ sudo -i
  root@controller:~# su - stack
  stack@controller:~$ cd devstack/
  stack@controller:~/devstack$ ./stack.sh

• prepare masakari-controller database in Controller

  stack@controller:~/devstack$ cd ~/masakari/
  stack@controller:~/masakari$ ./masakari_database_setting.sh

• start masakari-controller in Controller

  In Ubuntu,

  stack@controller:~/masakari$ sudo service masakari-controller start

  In CentOS,

  stack@compute1:~/devstack$ sudo systemctl enable masakari-controller.service

  • deploy OpenStack in Compute1 and Compute2 (execute respectively)

  $ vagrant ssh compute1
  vagrant@compute1:~$ sudo -i
  root@compute1:~# su - stack
  stack@compute1:~$ cd devstack/
  stack@compute1:~/devstack$ ./stack.sh

• start masakari monitors in Compute1 and Compute2 (execute respectively)

  In Ubuntu,

  stack@compute1:~/devstack$ sudo service masakari-hostmonitor start
  stack@compute1:~/devstack$ sudo service masakari-instancemonitor start
  stack@compute1:~/devstack$ sudo service masakari-processmonitor start

  In CentOS,

  stack@compute1:~/devstack$ sudo systemctl enable masakari-hostmonitor.service
  stack@compute1:~/devstack$ sudo systemctl enable masakari-instancemonitor.service
  stack@compute1:~/devstack$ sudo systemctl enable masakari-processmonitor.service

• set Compute2 as a reserved host of masakari, in Controller

  stack@controller:~/devstack$ cd ~/masakari
  stack@controller:~/masakari$ ./reserved_host_add.sh compute2

• disable Compute2 from nova scheduler

  stack@controller:~/masakari$ cd ~/devstack/
  stack@controller:~/devstack$ . openrc admin admin
  stack@controller:~/devstack$ nova service-disable compute2 nova-compute

• create a server instance

  stack@controller:~/devstack$ . openrc demo demo
  stack@controller:~/devstack$ nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.nano vm1

• check if the instance is running on Compute1

  stack@controller:~/devstack$ . openrc admin admin
  stack@controller:~/devstack$ nova hypervisor-servers compute1
  stack@controller:~/devstack$ nova hypervisor-servers compute2

• stop Compute1 suddenly, emulating Compute1 failure

  $ vagrant halt compute1 --force
  or
  $ vagrant destroy compute1 --force

• check if the instance is evacuated to Compute2 and running (Masakari automatically move the instance. It takes about 5 minutes until it moves.)

  stack@controller:~/devstack$ nova hypervisor-servers compute1
  stack@controller:~/devstack$ nova hypervisor-servers compute2
  $ nova --os-tenant-name demo instance-action-list vm2

• restart(recreate) a failed host with provisioner, Compute1

  $ vagrant up compute1 --provision

• deploy OpenStack in Compute1 (see above)

• start masakari monitors in Compute1 (see above)

• set Compute1 as a reserved host of masakari, in Controller

  stack@controller:~/devstack$ cd ~/masakari
  stack@controller:~/masakari$ ./reserved_host_add.sh compute1

• Compute1 was already disabled from nova scheduler by masakari at the time of a host failure

• enable Compute2 from nova scheduler

  stack@controller:~/masakari$ cd ~/devstack/
  stack@controller:~/devstack$ . openrc admin admin
  stack@controller:~/devstack$ nova service-enable compute2 nova-compute

• Compute2 was already excluded from reserved hosts of masakari at the time of a instance evacuation

• Now, the instance is ready for another host failure of Compute2

• store the whole VMs state to resume your work instantly in future

  $ vagrant suspend

  • resume the stored state

  $ vagrant up
