Get images¶
The simplest way to obtain a virtual machine image that works with
OpenStack is to download one that someone else has already
created. Most of the images contain the cloud-init package to
support the SSH key pair and user data injection.
Because many of the images disable SSH password authentication
by default, boot the image with an injected key pair.
You can SSH into the instance with the private key and default
login account. See Configure access and security for instances
for more information on how to create and inject key pairs with OpenStack.
