files for salt and salt-cloud to facilitate testing / working with the libra lbaas code

These files will enable one to create and configure vm's for:
  • the lbaas api server
  • the libra gearman worker nodes
  • the pool manager
  • apache test servers
  • stress servers


The primary requirement for working with this data is saltstack. All states were written / tested against ubuntu 12.04 vm's on hp's cloud

Primary documentation is located here and includes information on installation and configuration:

The file is intended to serve as the file server root as noted here:

The salt-cloud map files are intended to work with the naming conventions used in the top.sls file

The primary assumption is that this data will live on a salt-master and that minions will be created via salt-cloud.


salt-cloud is a tool that facilitates working with cloud instances and coordinating them via a salt-master Through the mapping and profile files, one can quickly create vm's and then configure them with salt. salt-cloud's delete functionality facilitates quick disposal of test vm's as well.

Configuration information is here:

For working with HP Cloud, there are additional notes. We are currently working with the salt-cloud / libcloud upstream maintainers to integrate our code to work with HP's cloud In the interim, libcloud and salt-cloud code that will work can be found here:

The primary changes are the introduction of some polling code to ensure vm's are ready / that we have public ip's available in libcloud and code to deal with HP-specific credentials in salt-cloud. Efforts are being taken to merge this code into a single OpenStack provider for salt-cloud.

cat /etc/salt/cloud
HPCLOUD.region: az-N.region-a.geo-1 # desired hp region
HPCLOUD.keyname: this-is-my-example-keyname # name of key in openstack 

 master: # name / ip address of the salt-master 

cat /etc/salt/cloud.profiles
 provider: hpcs
 image: 120 
 size: 102
 os: ubuntu
 ssh_username: ubuntu

map files

Map files can be used to specify sets of vm's that one wants to create based on salt-cloud profile information. An example:

/home/ubuntu# cat testmap.dat 
 - lbaas-api11
 - lbaas-api22

This means that if one calls salt-cloud to use this mapfile, that two servers - lbaas-api11 and lbaas-api22 - will be created based on the base_hp_az3 profile.

To create the vm's (the -P option is used to create the vm's in parallel)

/home/ubuntu# time salt-cloud -P -m testmap.dat 
The following virtual machines are set to be created:

Proceed? [N/y]y
Creating Cloud VM lbaas-api22
Creating Cloud VM lbaas-api11
<snip> The tool will bootstrap salt and register it with the specified master
Salt installed on lbaas-api11
Created Cloud VM lbaas-api11 with the following values:

 id: 3939
 name: lbaas-api11

real   1m26.749s
user   0m3.788s
sys    0m0.180s

Once finished, the nodes will be registered with the salt-master

/home/ubuntu# salt 'lbaas-api*'
lbaas-api11: True
lbaas-api22: True

To configure them, call state.highstate (one can target minions in a variety of ways - please refer to salt docs)

/home/ubuntu# time salt 'lbaas-api*' state.highstate

   State: - cmd
   Name:      ./ start
   Function:  run
       Result:    True
       Comment:   Command "./ start" run
       Changes:   pid: 12212
                  retcode: 0
                  stdout: starting lbaas ...
application : ./target/lbaas-0.0.1-jar-with-dependencies.jar
logging cfg : file:/home/ubuntu/lbaas/lbaas-10-24-2012/

real   2m56.536s
user   0m0.304s
sys    0m0.056s

The above example completed all of the steps necessary to create, build, and start an lbaas-api server and it was done quickly!
