Description
The
fabric:join command can be used in either of the following scenarios:
- You have an existing fabric, A, and you want to join a standalone container to fabric A.
- You have two separate fabrics, A and B, and you want to transfer a container from fabric B to fabric A.
Arguments
Table 10.31, “fabric:join Arguments” describes the command's arguments.
| Argument | Interpretation |
|---|---|
--help | Displays the online help for this command. |
-f, --force | Forces the provided container name to be used. |
-p, --profile | Specifies the profile to associate with the container after it joins the fabric. The fabric profile, which installs the Fabric Agent, is automatically assigned to all managed containers. |
-n, --non-managed | Registers the container with the fabric's ensemble, but does not install a Fabric Agent into the container. The container's configuration is not managed by the fabric and continues to behave like a standalone container except that it can be discovered through the fabric's ensemble. |
--zookeeper-password | The ensemble password for the fabric that you are trying to join. If you do not specify this option, you will be prompted to enter the password. |
-r, --resolver | Specifies the local resolver policy. Possible values are: localip, localhostname, publicip, publichostname, manualip. The default is localhostname. |
-m, --manual-ip | If you select the manualip resolver policy (using the --resolver option), specifies the IP address to use for the resolver. |
--min-port | Specifies the minimum port number of the allowed IP port range. Default is 0. |
--max-port | Specifies the maximum port number of the allowed IP port range. Default is 65535. |
URL | Specifies the URL of one of the Fabric Servers, specified in the format Host[:Port]. The Port value defaults to 2181. |
ContainerName | Specifies a unique name for the container to use when joining the fabric. By default, the value of the karaf.name property from the etc/system.properties file is used. |
Examples
The following command will add a standalone container to a fabric as a managed container:
fabric:join myhostA ishmael
fabric:join myhostA ishmael
Where
myhostA is the hostname of a Fabric Server (you must connect to a Fabric Server, not an ordinary fabric container) and the container is assigned the name ishmael. You will be prompted to enter the fabric's Zookeeper password.
Important
If the container being added to a fabric is assigned the same name as a container that is already a part of the fabric, the original container will be reset to have the same settings as the new container.
Warning
If no container name is specified as part of the command, the command will use the value of the
karaf.name property from the etc/system.properties file. The default setting for this property is root. To avoid conflicts, you should either specify a container name or change the value of the karaf.name property.
To make sure that the container starts up with a specific profile, you use the
-p argument as follows:
fabric:join -p whaler myhostA ishmael
fabric:join -p whaler myhostA ishmael
The container
ishmael is assigned the profile, whaler, when it joins the fabric.
If you want to be able to configure the container manually, but take advantage of the fabric's discovery features, you can add the container as a non-managed container using the following command:
fabric:join -n myhostA ishmael
fabric:join -n myhostA ishmael
