The code that would propage userdata to router, when updateVirtualMachine api
is called, was missing. As per the docs [0], userdata should be a base64 encoded
string upto 2KB which is put on domr's html directory adn using HTTP GET the
userdata information can be obtained from the domr.
The updateVirtualMachine api [0] would accept a base64 encoded string
and decoded and put into the domr's /var/www/html/userdata/<uservm ip>/user-data
file. The operation does not require the VM to be in stopped state, though it is
advised to stop and call this api in case the user vm has a script which gets
the userdata information from domr while starting.
For example, this script can be used to fetch the data:
server_ip=$(grep dhcp-server-identifier /var/lib/dhclient-eth0.leases | tail -1 | awk '{print $NF}' | tr '\;' ' ')
wget http://${server_ip}/latest/user-data
This feature can be useful, for example to use into puppet facts [1], or to do
automation and horizontal scaling etc. based on userdata.
