The compute component of
libcloud allows you to manage cloud and virtual
servers offered by different providers, more than 20 in total.
In addition to managing the servers this component also allows you to run deployment scripts on newly created servers. Deployment or “bootstrap” scripts allow you to execute arbitrary shell commands. This functionality is usually used to prepare your freshly created server, install your SSH key, and run a configuration management tool (such as Puppet, Chef, or cfengine) on it.
Besides managing cloud and virtual servers, compute component also allows you to manage cloud block storage (not to be confused with cloud object storage) for providers which support it. Block storage management lives under compute API, because it is in most cases tightly coupled with compute resources.
Node- represents a cloud or virtual server.
NodeSize- represents node hardware configuration. Usually this is amount of the available RAM, bandwidth, CPU speed and disk size. Most of the drivers also expose an hourly price (in dollars) for the Node of this size.
NodeImage- represents an operating system image.
NodeLocation- represents a physical location where a server can be.
NodeState- represents a node state. Standard states are:
Key Pair Management¶
KeyPair- represents an SSH key pair object.
StorageVolume- represents a block storage volume
VolumeSnapshot- represents a point in time snapshot of a StorageVolume
For majority of the compute providers Libcloud provides estimated pricing
information which tells users how much it costs per hour to run a
with a specific
For more information, please see the pricing page.
Libcloud provides deployment functionality which makes bootstrapping a server easier. It allows you to create a server and run shell commands on it once the server has been created.
For more information and examples, please see the deployment page.
SSH key pair management¶
Compute API also allows you to manage your SSH key pairs.
For more information and examples, please see the key pair management page.
