  • The following positional argument must be specified when creating experiments:<name> - The name for this experiment.The following options are applicable when creating experiments:-D <description>, --description <description> - description of the experiment. Defaults to “<no description>”.-W <walltime>, --walltime <walltime> - lifetime of the experiment in seconds. Defaults to one day.-G <group>, --group <group> - A user group this experiment will be accessible by. This option can be specified multiple times.The following positional arguments must be specified when creating storages (in that order):<name> - The name for this resource.<location> - The BonFIRE site where this resource will be created.Optionally, an experiment this resource will be part of can be specified as a third positional argument. The following options are applicable when creating storages:-D <description>, --description - The description of this storage resource. Defaults to “<no description>”.-S <size>, --size - Size of this storage resource in MiB. This is only applicable to datablock resources. Defaults to 1024 MiB.-T {datablock|shared} - The type of this storage resource. Note that “shared” storages are only available on be-ibbt. Defaults to “datablock”.-F <filesystem>, --fstype <filesystem> - The filesystem the storage resource will be formatted with. This is only applicable to datablock resources. Defaults to “ext3”.-G <group>, --group <group> - A user group this resource will be accessible by.

  • 3. Building service testbeds on FIREBonFIRE Experiment Lifecycle
  • 4. BonFIRE4 4Prerequisites• You must have an account in BonFIRE.– If you don’t, please go to:• http://www.bonfire-project.eu/involved• https://portal.bonfire-project.eu/register/• Your public key must be uploaded.– If not, you can find more information here:• http://doc.bonfire-project.eu/R3.1/getting-started/upload-ssh-key.html• You must have access to a SSH environment able toconnect through one the BonFIRE SSH gateways– If not, you can find more information here:• http://doc.bonfire-project.eu/R3.1/getting-started/ssh-gateway-config.html
  • 5. BonFIRE5 51. Create the experimentYou can choosebetween different toolsPortalCommand LineExperiment ManagerRestfullyCURL withOCCI• Don’t forget to set walltime properly. After it expires, theexperiment (and its resources) will be SHUTDOWN andDELETED.

  • 7. BonFIRE7 72. Set up the experiment• Create networks, VMs and Storages• If you want monitoring, don’t forget to add an Aggregator.– http://doc.bonfire-project.eu/R3.1/monitoring/howto.html

  • 15. BonFIRE15 154. Perform your experiment• Here you decide what to do!• If the experiment contains Virtual Wall (iMinds)resources, don’t forget to put in RUNNING state theexperiment.
  • 16. BonFIRE16 165. Monitoring• Access the Zabbix GUI, tunneled through the Portal.• Monitor Zabbix parameters, or configure your own.– BonFIRE offers application, VM and infrastructure monitoring fromthe same API• Use the monitoring API to make elasticity and applicationdecisions on the fly
  • 17. BonFIRE17 176. Wrap up your experiment• The experiment can finish in two different ways:– Expiry time (Walltime) ends.– You have finished before walltime arrives, and youdecide to stop or delete the experiment.• Before this time arrives, save the images anddatablocks that you want to use again. Then,shutdown the VM where the image/datablock is beingused.– http://doc.bonfire-project.eu/R3.1/reference/experiment-lifecycle.html
  • 18. BonFIRE18 187. After the experiment• Access the monitoring data that you have saved– http://doc.bonfire-project.eu/R3.1/monitoring/getting-data/export-csv.html• Reuse the images that you have configured and saved
