Cloud-Init How To

For the purpose of testing cloud-init local datasource, we can use vagrant to get a bare bones trusty box quick.

Look here for examples: https://cloudinit.readthedocs.org/en/latest/topics/examples.html

Local Provider - NoCloud

mkdir -p cloud-init/local-provider/vagrant

cd cloud-init/local-provider/vagrant

vagrant init ubuntu/trusty64; vagrant up --provider virtualbox

Ssh into the vagrant vm

vagrant ssh

Remove cloud-init files so node is in uninitialized state

rm -rf /var/lib/cloud/instance/*
rm -rf /var/lib/cloud/seed/nocloud-net/user-data

Create the user-data file in /var/lib/cloud/seed/nocloud-net/user-data with the contents

#cloud-config

runcmd:
 - echo "testtest" > /testfile.txt

Next run the commands to cloud-init your local instance

sudo cloud-init init --local
sudo cloud-init --debug modules -–mode config
sudo cloud-init --debug modules -–mode final
