Class CloudInstanceConfig

java.lang.Object

com.netflix.appinfo.AbstractInstanceConfig

com.netflix.appinfo.PropertiesInstanceConfig

com.netflix.appinfo.CloudInstanceConfig

All Implemented Interfaces:

EurekaInstanceConfig, RefreshableInstanceConfig

@Singleton
public class CloudInstanceConfig
extends PropertiesInstanceConfig
implements RefreshableInstanceConfig

An InstanceInfo configuration for AWS cloud deployments.

The information required for registration with eureka by a combination of user-supplied values as well as querying AWS instance metadata.An utility class AmazonInfo helps in retrieving AWS specific values. Some of that information including availability zone is used for determining which eureka server to communicate to.

Method Detail

resolveDefaultAddress

@Deprecated
public java.lang.String resolveDefaultAddress()

Deprecated. use resolveDefaultAddress(boolean)

resolveDefaultAddress

public java.lang.String resolveDefaultAddress(boolean refresh)

Description copied from interface: RefreshableInstanceConfig

resolve the default address

Specified by:

resolveDefaultAddress in interface RefreshableInstanceConfig

Returns:

getHostName

public java.lang.String getHostName(boolean refresh)

Description copied from interface: EurekaInstanceConfig

Gets the hostname associated with this instance. This is the exact name that would be used by other instances to make calls.

Specified by:

getHostName in interface EurekaInstanceConfig

Overrides:

getHostName in class AbstractInstanceConfig

Parameters:

refresh - true if the information needs to be refetched, false otherwise.

Returns:

hostname of this instance which is identifiable by other instances for making remote calls.

getIpAddress

public java.lang.String getIpAddress()

Description copied from interface: EurekaInstanceConfig

Get the IPAdress of the instance. This information is for academic purposes only as the communication from other instances primarily happen using the information supplied in EurekaInstanceConfig.getHostName(boolean).

Specified by:

getIpAddress in interface EurekaInstanceConfig

Overrides:

getIpAddress in class PropertiesInstanceConfig

Returns:

the ip address of this instance.

getDataCenterInfo

public DataCenterInfo getDataCenterInfo()

Description copied from interface: EurekaInstanceConfig

Returns the data center this instance is deployed. This information is used to get some AWS specific instance information if the instance is deployed in AWS.

Specified by:

getDataCenterInfo in interface EurekaInstanceConfig

Overrides:

getDataCenterInfo in class AbstractInstanceConfig

Returns:

information that indicates which data center this instance is deployed in.

getDefaultAddressResolutionOrder

public java.lang.String[] getDefaultAddressResolutionOrder()

Description copied from interface: EurekaInstanceConfig

An instance's network addresses should be fully expressed in it's DataCenterInfo. For example for instances in AWS, this will include the publicHostname, publicIp, privateHostname and privateIp, when available. The InstanceInfo will further express a "default address", which is a field that can be configured by the registering instance to advertise it's default address. This configuration allowed for the expression of an ordered list of fields that can be used to resolve the default address. The exact field values will depend on the implementation details of the corresponding implementing DataCenterInfo types.

Specified by:

getDefaultAddressResolutionOrder in interface EurekaInstanceConfig

Overrides:

getDefaultAddressResolutionOrder in class PropertiesInstanceConfig

Returns:

an ordered list of fields that should be used to preferentially resolve this instance's default address, empty String[] for default.

refreshAmazonInfo

@Deprecated
public void refreshAmazonInfo()

Deprecated. 2016-09-07 Refresh instance info - currently only used when in AWS cloud as a public ip can change whenever an EIP is associated or dissociated.
