getPortCount

public int getPortCount()

Description copied from interface: NetworkPortRequestor

Returns the number of ports needed by this service. User-defined ports for container http servers should not be counted, as those ports are required to be outside Vespa's port range.

allocatePorts

public void allocatePorts(int start,
 PortAllocBridge from)

Description copied from interface: NetworkPortRequestor

allocate the ports you need

getStartupCommand

public String getStartupCommand()

Description copied from class: AbstractService

Must be overridden by services that should be started by config-sentinel. The returned value will be used in config-sentinel configuration. Returns null by default.

Specified by:

getStartupCommand in interface Service

Overrides:

getStartupCommand in class AbstractService

Returns:

null by default.

getIndex

protected int getIndex(HostResource host)

Different services are represented using same class here, so we must take service name into account too

Overrides:

getIndex in class AbstractService

Parameters:

host - a host

Returns:

the index of the host

getServiceType

public String getServiceType()

Description copied from class: AbstractService

Returns the type of service. This is the class name without the package prefix by default, never null

Specified by:

getServiceType in interface NetworkPortRequestor

Overrides:

getServiceType in class AbstractService
