Provide random seed data

For a full list of keys, refer to the seed random module schema.

Example 1

1#cloud-config
2random_seed:
3  command: [sh, -c, dd if=/dev/urandom of=$RANDOM_SEED_FILE]
4  command_required: true
5  data: my random string
6  encoding: raw
7  file: /dev/urandom

Example 2

This example uses pollinate to gather data from a remote entropy server, and writes that data to /dev/urandom:

1#cloud-config
2random_seed:
3  command: [pollinate, '--server=http://local.pollinate.server']
4  command_required: true
5  file: /dev/urandom
