Class CloudSeedNodeProvider

java.lang.Object

io.hekate.cluster.seed.jclouds.CloudSeedNodeProvider

All Implemented Interfaces:

io.hekate.cluster.seed.SeedNodeProvider, io.hekate.core.report.ConfigReportSupport

public class CloudSeedNodeProvider
extends Object
implements io.hekate.cluster.seed.SeedNodeProvider, io.hekate.core.report.ConfigReportSupport

Cloud instance-based implementation of SeedNodeProvider interface.

This provider uses ComputeService to get meta-information about all instances that are running in the cloud. Addresses of those instances will be used as seed nodes for ClusterService cluster.

Important: all Hekate cluster nodes must be configured to run on the same port.

Filtering of seed node instances can be done by specifying different configuration options in CloudSeedNodeProviderConfig. For example:

• filter by regions - to scan instances only within a limited set of cloud regions
• filter by zones - to scan instances only within a limited set of availability zones
• filter by tags - to scan only those instances that have the specified set of tags

Please see the documentation of CloudSeedNodeProviderConfig class for more details about the available configuration options.
