Field Detail

tunnel

@CheckForNull
public final String tunnel

If the agent needs to tunnel the connection to the controller, specify the "host:port" here. This can include the special syntax "host:" and ":port" to indicate the default host/port shall be used.

Null if no tunneling is necessary.

JNLPLauncher

@Deprecated
public JNLPLauncher(@CheckForNull
                                String tunnel,

Deprecated.

Constructor.

Parameters:

tunnel - Tunnel settings

vmargs - JVM arguments

workDirSettings - Settings for Work Directory management in Remoting. If null, RemotingWorkDirSettings.getEnabledDefaults() will be used to enable work directories by default in new agents.

Since:

2.68

JNLPLauncher

@DataBoundConstructor
public JNLPLauncher(@CheckForNull
                                          String tunnel,

JNLPLauncher

@Deprecated
public JNLPLauncher()

Deprecated. This Launcher does not enable the work directory. It is recommended to use JNLPLauncher(boolean)

JNLPLauncher

public JNLPLauncher(boolean enableWorkDir)

Constructor with default options.

Parameters:

enableWorkDir - If true, the work directory will be enabled with default settings.

Method Detail

readResolve

protected Object readResolve()

getWorkDirSettings

@NonNull
public RemotingWorkDirSettings getWorkDirSettings()

Returns work directory settings.

Since:

2.72

setWorkDirSettings

@DataBoundSetter
public final void setWorkDirSettings(@NonNull
                                                      RemotingWorkDirSettings workDirSettings)

isLaunchSupported

public boolean isLaunchSupported()

Description copied from class: ComputerLauncher

Returns true if this ComputerLauncher supports programmatic launch of the agent in the target Computer.

Overrides:

isLaunchSupported in class ComputerLauncher

isWebSocket

public boolean isWebSocket()

Since:

2.216

setWebSocket

@DataBoundSetter
public void setWebSocket(boolean webSocket)

Since:

2.216

launch

public void launch(SlaveComputer computer,
                   TaskListener listener)

Description copied from class: ComputerLauncher

Launches the agent for the given Computer.

If the agent is launched successfully, SlaveComputer.setChannel(InputStream, OutputStream, TaskListener, Channel.Listener) should be invoked in the end to notify Hudson of the established connection. The operation could also fail, in which case there's no need to make any callback notification, (except to notify the user of the failure through StreamTaskListener.) Also note that the normal return of this method call does not necessarily signify a successful launch. If someone programmatically calls this method and wants to find out if the launch was a success, use Computer.isOnline() at the end.

This method must operate synchronously. Asynchrony is provided by Computer.connect(boolean) and its correct operation depends on this.

Overrides:

launch in class ComputerLauncher

listener - The progress of the launch, as well as any error, should be sent to this listener.

getWorkDirOptions

@NonNull
 @Restricted(value=org.kohsuke.accmod.restrictions.NoExternalUse.class)
public String getWorkDirOptions(@NonNull
                                                                                                                 Computer computer)

Gets work directory options as a String. In public API getWorkDirSettings().toCommandLineArgs(computer) should be used instead

Parameters:

computer - Computer

Returns:

Command line options for launching with the WorkDir

isJavaWebStartSupported

@Restricted(value=org.kohsuke.accmod.restrictions.NoExternalUse.class)
public boolean isJavaWebStartSupported()

Returns true if Java Web Start button should be displayed. Java Web Start is only supported when the Jenkins server is running with Java 8. Earlier Java versions are not supported by Jenkins. Later Java versions do not support Java Web Start. This flag is checked in config.jelly before displaying the Java Web Start button.

Returns:

true if Java Web Start button should be displayed.

Since:

2.153

getInboundAgentUrl

@Restricted(value=org.kohsuke.accmod.restrictions.NoExternalUse.class)
public static String getInboundAgentUrl()

Overrides the url that inbound TCP agents should connect to as advertised in the agent.jnlp file. If not set, the default behavior is unchanged and returns the root URL. This enables using a private address for inbound tcp agents, separate from Jenkins root URL.
