distem_cmd.md

First do the same Grid'5000 stuff always required:

frontend oarsub -t deploy -l slash_22=1+nodes=3,walltime=00:50:00 -I g5k-subnets -sp -> 10.144.4.0/22 kadeploy3 -f $OAR_NODE_FILE -e debian9-x64-nfs -k distem-bootstrap --debian-version stretch

• note: store address returned by second step =========== EXPERIMENT: ===========

switch to coordinator node

frontend> ssh root@grisou-34

coord>

create virtual network

distem --create-vnetwork vnetwork=vnetwork,address=10.144.4.0/22

SKIP THIS IF YOU HAVE FILESYS IMG

###########

go back to frontend

coord> exit

#download system image (skip if done before) frontend> wget 'http://public.nancy.grid5000.fr/~amerlin/distem/distem-fs-jessie.tar.gz' -P ~/distem_img

switch to coord

ssh root@grisou-34 ##################

create virtual nodes

coord distem --create-vnode vnode=node-1,pnode=grisou-34,
rootfs=file:///home/ksonbol/distem_img/distem-fs-jessie.tar.gz,
sshprivkey=/root/.ssh/id_rsa,sshpubkey=/root/.ssh/id_rsa.pub

distem --create-vnode vnode=node-2,pnode=grisou-34,
rootfs=file:///home/ksonbol/distem_img/distem-fs-jessie.tar.gz,
sshprivkey=/root/.ssh/id_rsa,sshpubkey=/root/.ssh/id_rsa.pub

create network interfaces on each vnode

coord distem --create-viface vnode=node-1,iface=if0,vnetwork=vnetwork distem --create-viface vnode=node-2,iface=if0,vnetwork=vnetwork

node1-address: 10.144.4.1/22 node2-address: 10.144.4.2/22

distem --start-vnode node-1 distem --start-vnode node-2

connection in a node to get a shell (user:root, password:root):

coord> distem --shell node-1

This option uses lxc-console, so the exit key sequence (ctrl-a + q by default) can be modified if you are running inside a screen session.

execution of a command:

coord> distem --execute vnode=node-1,command="hostname"
