Managing Instances
|
|
==================
|
|
|
|
Keypairs
|
|
--------
|
|
|
|
Images can be shared by many users, so it is dangerous to put passwords into the images. Nova therefore supports injecting ssh keys into instances before they are booted. This allows a user to login to the instances that he or she creates securely. Generally the first thing that a user does when using the system is create a keypair. Nova generates a public and private key pair, and sends the private key to the user. The public key is stored so that it can be injected into instances.
|
|
|
|
Keypairs are created through the api. They can be created on the command line using the euca2ools script euca-add-keypair. Refer to the man page for the available options. Example usage::
|
|
|
|
euca-add-keypair test > test.pem
|
|
chmod 600 test.pem
|
|
euca-run-instances -k test -t m1.tiny ami-tiny
|
|
# wait for boot
|
|
ssh -i test.pem root@ip.of.instance
|
|
|
|
|
|
Basic Management
|
|
----------------
|
|
Instance management can be accomplished with euca commands:
|
|
|
|
|
|
To run an instance:
|
|
|
|
::
|
|
|
|
euca-run-instances
|
|
|
|
|
|
To terminate an instance:
|
|
|
|
::
|
|
|
|
euca-terminate-instances
|
|
|
|
To reboot an instance:
|
|
|
|
::
|
|
|
|
euca-reboot-instances
|
|
|
|
See the euca2ools documentation for more information
