Deploying Applications Using an asadmin Command

You can deploy applications using the equivalent administration commands present on Payara Server.

Deploying on a Local Instance

It’s possible to use the run(Collection<InstanceDescriptor> members, String command, String… args ) method to run the deploy asadmin command. To deploy to a single instance, you must create a members Collection object only containing a single instance, like in the following example:

import fish.payara.micro.PayaraMicro;
import fish.payara.micro.BootstrapException;
import fish.payara.micro.PayaraMicroRuntime;
import fish.payara.micro.services.data.InstanceDescriptor;
import java.util.ArrayList;
import java.util.Collection;

public class EmbeddedPayara {
    public static void main(String[] args) throws BootstrapException {
        PayaraMicroRuntime runtime = PayaraMicro.getInstance().setHttpAutoBind(true).bootstrap();

        // Get a Collection with all running instances in the local runtime's cluster
        Collection<InstanceDescriptor> allInstances = runtime.getClusteredPayaras();

        // Create a Collection to use as a subset
        Collection<InstanceDescriptor> subset = new ArrayList<>();

        // Loop through all instances
        for (InstanceDescriptor instance : allInstances){
            // Only add the local instance
            if (instance == runtime.getLocalDescriptor()){
                subset.add(instance);
                break;
            }
        }

        // Run the deploy asadmin command on the subset Collection
        runtime.run(subset, "deploy", "/home/user/test.war");
    }
}

Deploying an Application to Multiple Bootstrapped Instances

You can use the run method to run the deploy asadmin command on multiple clustered instances. There are two run methods available for running administration commands: one which runs an asadmin command on a subset of instances in a cluster, and another than runs an asadmin command on all instances in a cluster.

More detail on these can be found in the Running Asadmin Commands on Bootstrapped Instances section.

Here is an example of deploying an application to all instances in a cluster:

import fish.payara.micro.PayaraMicro;
import fish.payara.micro.BootstrapException;
import fish.payara.micro.PayaraMicroRuntime;

public class EmbeddedPayara{
    public static void main(String[] args) throws BootstrapException{
        PayaraMicroRuntime runtime = PayaraMicro.getInstance().setHttpAutoBind(true).bootstrap();

        // Run the deploy asadmin command on all instances in the runtime's cluster
        runtime.run("deploy", "/home/user/test.war");
    }
}

See the example for deploying on local instance on using the run method on a subset of instances in a cluster.
