The Snooze Grid`5000 multi site deployement script

• Make a reservation :

    (frontend)$ oargridsub -t deploy -w 1:00:00 rennes:rdef="{\\\\\\\"type='kavlan-global'\\\\\\\"}/vlan=1+/slash_22=1+/nodes=3",lyon:rdef=/nodes=3,sophia:rdef=/nodes=3 > ~/oargrid.out
  

NB1 : On a single site you don't need to reserve a vlan. The reservation could be :

    (frontend)$ oarsub -I -t deploy -l slash_22=1,nodes=10,walltime=8

NB2 : With a multisite reservation, the file oargrid.out is used by the script so it must be placed in your home directory.

If everything is fine this file looks like :

rennes:rdef={\\\"type='kavlan-global'\\\"}/vlan=1+/slash_22=1,lyon:rdef=/nodes=3,sophia:rdef=/nodes=3
[OAR_GRIDSUB] [rennes] Date/TZ adjustment: 0 seconds
[OAR_GRIDSUB] [rennes] Reservation success on rennes : batchId = 471354
[OAR_GRIDSUB] [lyon] Date/TZ adjustment: 0 seconds
[OAR_GRIDSUB] [lyon] Reservation success on lyon : batchId = 599979
[OAR_GRIDSUB] [sophia] Date/TZ adjustment: 0 seconds
[OAR_GRIDSUB] [sophia] Reservation success on sophia : batchId = 530702
[OAR_GRIDSUB] Grid reservation id = 42581
[OAR_GRIDSUB] SSH KEY : /tmp/oargrid//oargrid_ssh_key_msimonin_42581
  You can use this key to connect directly to your OAR nodes with the oar user.

• Connect to your job (with the subnet reservation):

    (frontend)$ oarsub -C 471354
  

• Configure the proxy :

    (frontend)$ export https_proxy="http://proxy:3128"
  

• Clone the git repository :

    (frontend)$ git clone https://github.com/msimonin/snooze-grid5000-multisite.git 
  

• Download latest version of debian package (snoozenode is require, snoozeclient is optional) :

    (frontend)$ cd ~/snooze-grid5000-multisite/grid5000/deployscript/deb_packages/
    (frontend)$ wget https://ci.inria.fr/snooze-software/job/master-snoozenode/ws/distributions/deb-package/snoozenode_1.1.0-0_all.deb  
    (frontend)$ wget https://ci.inria.fr/snooze-software/job/master-snoozeclient/ws/distributions/deb-package/snoozeclient_1.1.0-0_all.deb  
  

Other packages could be found in https://ci.inria.fr/snooze-software/.

• Configure the number of nodes in the settings.sh and the deployment type :

    (frontend)$ cd ~/snooze-grid5000-multisite/grid5000/deployscript/
    (frontend)$ vi scripts/settings.sh
  
    multisite=true|false
    storage_type="nfs|local"
    number_of_bootstrap_nodes=1
    number_of_group_managers=2
    number_of_local_controllers=5
  

NB : Since we use a "service node" for the deployment you will get a Snooze cluster running with n-1 nodes. NB2 : If you set storage type to "local", the VMs base images will be propagated by scp-tsunami, you have to install it in /opt of the first bootstrap (see settings.sh of experiments scripts).

• Retrieve VMs base images in ~/vmimages/ You can get my debian base image in /home/msimonin/vmimages in Rennes

    (frontend)$ scp -r <yourlogin>@rennes:/home/msimonin/vmimages ~/.
  

• Launch the automatic script :

    (frontend)$ ./snooze_deploy.sh -a
  

• Connection to the service node :

    (frontend)$ cat tmp/service_node.txt
    (frontend)$ ssh -l root <service node>
  

• Connection to the first bootstrap :

    (service)$ cd /tmp/service/snooze-grid5000-multisite/grid5000/deployscript/
    (service)$ cat tmp/bootstrap_nodes.txt
    (service)$ ssh -l root <first bootstrap>
  

• Launching VMs :

The first bootstrap node hosts some helper to launch VMs.

    (bootstrap)$ cd /tmp/snooze/experiments
    (bootstrap)$ ./experiments -c test 5
    (bootstrap)$ snoozeclient start -vcn test

These commands will create and start 10 VMs.

• Visualizing the system : Make a tunnel (or export your display) from your laptop to the bootstrap through the grid'5000 frontend on port 5000. If snoozeclient is installed on your PC, you can launch :

    (PC) snoozeclient visualize.
