Fuse ESB Enterprise - Configuring and Running Fuse ESB Enterprise - Connecting to a Fabric Container From another Fabric Container

Connecting to a Fabric Container From another Fabric Container

Overview

When containers are deployed into a fabric, they are all connected to each other. You can easily connect to any container's command console from any of its peers. When connecting using fabric, you do not need to know any of the location details for the container you want to connect to. The fabric's runtime registry stores all of the location details needed to establish the remote connection.

Using the fabric:container-connect command

In the context of a fabric, you should connect to a remote runtime's console using the fabric:container-connect command.

Example 9. fabric:container-connect Command Syntax

fabric:container-connect {-u username} {-p password} {containerName}

-u username: The username used to connect to the remote console. The default value is admin.
-p password: The password used to connect to the remote console. The default value is admin.
containerName: The name of the container.

	Warning
	We recommend that you change the default administrator username and password. See Configuring JAAS Security for details.

Example 10. Connecting to a Remote Container

karaf@root>fabric:container-connect -u admin -p admin containerName

To confirm that you have connected to the correct container, type shell:info at the prompt. Information about the currently connected instance is returned, as shown in Example 11.

Disconnecting from a remote console

To disconnect from a remote console, enter logout or press Ctrl+D at the prompt.

You will be disconnected from the remote container and the console will once again manage the local container.
