Returns the current installed processes which may or may not be running right now

Specified by:

listInstallations in interface ProcessManager

listInstallationMap

public com.google.common.collect.ImmutableMap<String,Installation> listInstallationMap()

Specified by:

listInstallationMap in interface ProcessManager

getInstallation

public Installation getInstallation(String id)

Description copied from interface: ProcessManager

Returns the installation for the given ID or null if the installation does not exist

Specified by:

getInstallation in interface ProcessManager

getInstallationIds

@JmxManaged(description="Returns the set of installed processes")
public String getInstallationIds()

getInstallationCount

@JmxManaged(description="Returns the number of installed processes")
public int getInstallationCount()

install

public Installation install(InstallOptions options,
                   InstallTask postInstall)
                     throws Exception

Description copied from interface: ProcessManager

Installs a process with an optional URL of the controller JSON together with an optional install step

Specified by:

install in interface ProcessManager

Throws:

Exception

getDownloadStrategy

protected DownloadStrategy getDownloadStrategy(InstallOptions options)

allocatePorts

protected void allocatePorts(InstallOptions options,
                 File nestedProcessDirectory)
                      throws IOException

Throws:

getLocalHostName

public static String getLocalHostName()
                               throws UnknownHostException

When using the InetAddress.getHostName() method in an environment where neither a proper DNS lookup nor an /etc/hosts entry exists for a given host, the following exception will be thrown: java.net.UnknownHostException: <hostname>: <hostname> at java.net.InetAddress.getLocalHost(InetAddress.java:1425) ... Instead of just throwing an UnknownHostException and giving up, this method grabs a suitable hostname from the exception and prevents the exception from being thrown. If a suitable hostname cannot be acquired from the exception, only then is the UnknownHostException thrown.

Returns:

The hostname

Throws:

UnknownHostException
