Pluggable Provisioning Mechanism
|
|
================================
|
|
|
|
Sahara could be integrated with 3rd party management tools like Apache Ambari
|
|
and Cloudera Management Console. The integration is achieved using plugin
|
|
mechanism.
|
|
|
|
In short, responsibilities are divided between Sahara core and plugin as
|
|
follows. Sahara interacts with user and provisions infrastructure (VMs).
|
|
Plugin installs and configures Hadoop cluster on the VMs. Optionally Plugin
|
|
could deploy management and monitoring tools for the cluster. Sahara
|
|
provides plugin with utility methods to work with VMs.
|
|
|
|
A plugin must extend `sahara.plugins.provisioning:ProvisioningPluginBase`
|
|
class and implement all the required methods. Read :doc:`plugin.spi` for
|
|
details.
|
|
|
|
The `instance` objects provided by Sahara have `remote` property which
|
|
could be used to work with VM. The `remote` is a context manager so you
|
|
can use it in `with instance.remote:` statements. The list of available
|
|
commands could be found in `sahara.utils.remote.InstanceInteropHelper`.
|
|
See Vanilla plugin source for usage examples.
