Machine: userdata not working for digitalocean

[taarimalta]

How do I get --digitalocean-userdata to work?

For example, I tried to install cowsay using userdata but failed

docker-machine create \
--driver digitalocean \
--digitalocean-image  ubuntu-14-04-x64 \
--digitalocean-access-token <token> \
--digitalocean-size 512mb \
--digitalocean-region nyc1 \
--digitalocean-userdata worker_provision.sh \
--digitalocean-private-networking worker-1 \

where worker_provision.sh is

#cloud-config

runcmd:
    - apt-get install cowsay

After running the create command,

To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env worker-1

But when I run

docker-machine ssh worker-1

I get the following message

The program 'cowsay' is currently not installed. You can install it by typing:
apt-get install cowsay

I have tried to follow the following guidelines:

Is there any interesting log in /var/log/cloud-init-output.log? Also the page you're linking suggests apt-get -y install [package].

I realized that my mistake was to place a tab(t) character instead of spaces in front of the hyphen. It works!
