Pass variables to ansible playbooks

ansible

I need to pull a build from S3 on my target machine. Therefore I need to pass the S3 key and secret to the ansible playbook somehow.

I know that I could define them in

the inventory
the playbook itself

but I really don't want to store credentials there.

Can I use environment variables from the local machine (or something similar) in an ansible playbook?

$ENV(SOMEVAR) or {{ lookup('env', 'SOMEVAR') }} (1.1+) should work. You could also use vars_prompt to request it at playbook runtime.

Yes. I've removed my access/secret keys across Ansible and use IAM roles. Note you'll need some role permissions on the "server" and others on the destination boxes.

Optimizing Ansible playbooks to run against many hosts

First of all, you need to consider caching the facts.

Take a look here for how to:

http://docs.ansible.com/ansible/playbooks_variables.html#fact-caching

You will see an amazing performance on gather-facts, even with caching to a file.

Then you may consider of improving the level of parallelism with -f

man ansible-playbook

   -f NUM, --forks=NUM
       Level of parallelism.  NUM is specified as an integer, the default is 5.

to something bigger than 5
