Launches one or more instances of the specified AMI. An
optional security group in which new instances should be launched
may be specified. If no group is specified instances are launched
in the default group. A keypair name may also
be specified. If provided, the public key associated with this
keypair will be made available to the instances at boot time.
A table containing the following information is returned:
Output type identifier ("INSTANCE")
Instance ID which uniquely identifies each running instance.
AMI ID of the image the instance is based on.
DNS name associated with the instance (only present for instances in the running state).
Instance state. This will in most cases be
pending which indicates that the instance is
being prepared for launch.
Key name. If a key was associated with the instance at launch it's name will be displayed in this column.
Errors are displayed on stderr.
| Option | Definition | Required? | Example |
|---|---|---|---|
-n INSTANCE_COUNT | The number of instances to launch. If
not specified, a value of
1 will be assumed. If it
is not possible to launch at least this many
instances (due to a lack of capacity or
funds), no instances will be launched. If
specified as a range (min-max) Amazon EC2 will
try to launch as many instances as possible,
up to max, but will launch no fewer than min
instances.
| No | -n 5 |
-g GROUP | The security group(s) within which the instance(s) should be run. This determines the ingress firewall rules that will be applied to the instances. By default instances will run in the user's default group. If more than one group is specified, the security policy of the instances will be the union of the security policies of the specified groups. | No | -g fooGroup |
-k KEY | The keypair to make available to these instances at boot time. | No | -k fooKeyPair |
