DockerTransientNode

@Deprecated
public DockerTransientNode(@NonNull
 String nodeName,
 @NonNull
 String containerId,
 String workdir,
 ComputerLauncher launcher)
                    throws Descriptor.FormException,
IOException

Deprecated.

Use DockerTransientNode(String, String, String) then Slave.setLauncher(ComputerLauncher).

Parameters:

nodeName - Passed to DockerTransientNode(String, String, String).

containerId - Passed to DockerTransientNode(String, String, String).

workdir - Passed to DockerTransientNode(String, String, String).

launcher - Passed to Slave.setLauncher(ComputerLauncher)

Throws:

Descriptor.FormException - See DockerTransientNode(String, String, String).

IOException - See DockerTransientNode(String, String, String).

DockerTransientNode

public DockerTransientNode(@NonNull
 String nodeName,
 @NonNull
 String containerId,
 String workdir)
                    throws Descriptor.FormException,
IOException

Preferred constructor. Note that, unless this is a JNLP node, callers will later have to call Slave.setLauncher(ComputerLauncher).

Parameters:

nodeName - Name of the node; passed to AbstractCloudSlave(String, String, ComputerLauncher).

containerId - Docker container id.

workdir - remoteFs home dir; passed to AbstractCloudSlave(String, String, ComputerLauncher).

Throws:

Descriptor.FormException - See AbstractCloudSlave(String, String, ComputerLauncher).

IOException - See AbstractCloudSlave(String, String, ComputerLauncher).

Method Details

isAcceptingTasks

public boolean isAcceptingTasks()

Overrides:

isAcceptingTasks in class Node

setAcceptingTasks

public void setAcceptingTasks(boolean acceptingTasks)

getContainerId

@NonNull
public String getContainerId()

setDockerAPI

public void setDockerAPI(DockerAPI dockerAPI)

getDockerAPI

public DockerAPI getDockerAPI()

Returns:

The DockerAPI for our cloud.

getDisplayName

public String getDisplayName()

Specified by:

getDisplayName in interface ModelObject

Overrides:

getDisplayName in class Node

isRemoveVolumes

public boolean isRemoveVolumes()

setRemoveVolumes

public void setRemoveVolumes(boolean removeVolumes)

getStopTimeout

public int getStopTimeout()

setStopTimeout

public void setStopTimeout(int timeout)

getCloudId

public String getCloudId()

setCloudId

public void setCloudId(String cloudId)

getProvisioningId

public org.jenkinsci.plugins.cloudstats.ProvisioningActivity.Id getProvisioningId()

setProvisioningId

public void setProvisioningId(org.jenkinsci.plugins.cloudstats.ProvisioningActivity.Id provisioningId)

createComputer

public DockerComputer createComputer()

Specified by:

createComputer in class AbstractCloudSlave

getId

@Nullable
public org.jenkinsci.plugins.cloudstats.ProvisioningActivity.Id getId()

Specified by:

getId in interface org.jenkinsci.plugins.cloudstats.TrackedItem

_terminate

@Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class)
public void _terminate(TaskListener listener)

Specified by:

_terminate in class AbstractCloudSlave

terminate

@Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class)
public void terminate(org.slf4j.Logger logger)

Tries to remove all trace of this node, logging anything that goes wrong.

Note: This is not intended for use outside the plugin.

Parameters:

logger - Where to log any progress messages, exceptions etc.

stopAndRemoveContainer

@Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class)
public static boolean stopAndRemoveContainer(DockerAPI api,
 org.slf4j.Logger logger,
 String containerDescription,
 boolean removeVolumes,
 String containerId,
 boolean containerAlreadyStopped)

Utility method that gracefully terminates a docker container (preferably one that we started). Intended to only be used when we do not have a corresponding DockerTransientNode - if we have a DockerTransientNode then call terminate(Logger) instead.

Parameters:

api - The DockerAPI which we are to use.

logger - Where to log progress/results to.

containerDescription - What the container was, e.g. "for node 'docker-1234'" or "for non-existent node". Used in logs.

removeVolumes - If true then we'll ask docker to remove the container's volumes as well.

containerId - The ID of the container to be terminated.

containerAlreadyStopped - If true then we will assume that the container is already stopped and not try to stop it again (which helps prevent verbose warnings from appearing in the Jenkins log outside our control). If you're not sure, pass in false.

Returns:

true if the container is now stopped and removed. false if we could not remove it (in which case we will have logged the reason why).

getCloud

public DockerCloud getCloud()

robustlyAddToJenkins

@Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class)
public void robustlyAddToJenkins()
                          throws IOException

Robustly adds this node to Jenkins. This works around for Jenkins core issue in Nodes.java's addNode method.. There's a line there saying "TODO there is a theoretical race whereby the node instance is updated/removed after lock release". When we're busy adding nodes this is not merely "theoretical"!

Throws:

IOException - if it all failed horribly every time we tried.

See Also:

• Nodes.java addNode method

robustlyRemoveFromJenkins

@Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class)
public void robustlyRemoveFromJenkins()
                               throws IOException

Reverse of robustlyAddToJenkins().

Throws:

IOException - if it all failed horribly.
