The correct way to do this is with boto profiles.

You should have a 'credentials' file in your $HOME/.aws directory, and it should look something like this:

​

[default]

aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID

aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY

​

[project1]

aws_access_key_id = ANOTHER_AWS_ACCESS_KEY_ID

aws_secret_access_key = ANOTHER_AWS_SECRET_ACCESS_KEY

​

Then, when it is time to run your playbook, you do something like:

​

ansible-playbook PLAYBOOK.yml --profile project1

ansible-playbook ANOTHERPLAYBOOK.yml --profile default

​

Hope that helps!
