Description
This command is used to create a new fabric. It can also be used to change the Fabric Servers in an existing fabric. Converting the current container into a fabric has two important side effects:
- The contents of a container should now be managed using fabric profiles. Do not try to deploy bundles and features directly in a fabric container.
- The default JAAS realm is superseded by the Zookeeper login module, which stores user data in the Zookeeper registry. As the fabric is created it initializes the user data by importing all of the user data that it finds in the
etc/users.propertiesfile. If theusers.propertiesfile is empty, you can specify a new user explicitly using the--new-userand--new-user-passwordoptions (at least one user must be defined).
If you want to create your own import directory with custom profile data, it is recommended that you proceed as follows:
- Create a fabric that imports the sample profiles (for example, using
fabric:create). - Modify the sample profiles using the
fabric:profile-create,fabric:profile-delete, andfabric:editcommands. - Export the modified profiles using the
fabric:exportcommand.
Arguments
Table 8.23, “fabric:create Arguments” describes the command's arguments.
| Argument | Interpretation |
|---|---|
--help | Displays the online help for this command |
--clean | Clean local zookeeper cluster and configurations. |
--no-import | Disable the import of the sample registry data. |
--import-dir | Directory of files to import into the newly created ensemble. |
-v, --verbose | Flag to enable verbose output of files being imported. |
-t, --time | How long to wait (milliseconds) for the ensemble to start up, before trying to import the default data. |
-n, --non-managed | Specifies that the container remains unmanaged. |
-p, --profile | Specifies the profile to use for the ensemble containers in the new fabric. |
--new-user |
Create a new user in the new fabric's JAAS realm. Because the
fabric:create command automatically imports user data from the etc/users.properties file, you would only need to specify this option, if the etc/users.properties file contains no valid user entries.
When using this option, you must also specify a password using the
--new-user-password option.
|
--new-user-password | Used in combination with the --new-user option to specify the new user's password. No default value. |
--new-user-role | Used in combination with the --new-user option to specify the new user's role. Default is admin. |
--zookeeper-password |
Specifies the Zookeeper password, which is used to access the Zookeeper nodes under the
/fabric/ path. Defaults to the password of the current session user.
Subsequently, because the Zookeeper password is cached in the current session, you normally do not need to provide it when executing fabric commands. You can display the Zookeeper password at any time using the
fabric:ensemble-password command.
|
--generate-zookeeper-password | Directs Fabric to generate a random Zookeeper password. Subsequently, you can display the Zookeeper password using the fabric:ensemble-password command. |
-g, --global-resolver | Specifies the global resolver policy, which becomes the default resolver policy applied to all new containers created in this fabric. Possible values are: localip, localhostname, publicip, publichostname, manualip. The default is localhostname. |
-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 either the --resolver or --global-resolver options), 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. |
ContainerList | The list of containers to include in the ensemble. An empty list implies the current container. |
Examples
Create a fabric and import sample profiles from the
ESBInstallDir/fabric/import directory, as follows:
fabric:create --clean
Create a fabric without imported profiles, as follows:
fabric:create --clean --no-import
Create a fabric and import profiles from the custom import directory, CustomImportDir, as follows:
fabric:create --clean --import-dir CustomImportDir
Re-create a fabric such that the containers,
reg1, reg2, and reg3, are now included in the registry ensemble (an ensemble must consist of an odd number of containers):
fabric:create reg1 reg2 reg3
In this case, the contents of the Zookeeper registry are preserved and the ensemble is expanded to include the specified containers.
