Description
Specifically, this command provisions the container as follows:
- Logs into the specified SSH host, using either the provided username and password or using the provided username and private key.
- Runs a script on the remote host that that downloads the container runtime to the remote host. The runtime files are downloaded through a Maven proxy server. By default, the script uses the oldest Maven proxy server in the current ensemble (every Fabric Server has a Maven proxy server deployed in it). You can optionally override the default Maven proxy by specifying the
--proxy-urioption. The script would then use the specified Maven proxy server to download the container runtime.NoteThe ability to override the Maven proxy is important in certain cases (for example, in a cloud deployment) where the remote host might not be able to access the default Maven proxy server. - Starts up the newly installed container (or containers) and installs the specified fabric profile (or profiles).
By default, the newly created containers belong to the current fabric (that is, the same fabric as the container from which you invoked the command). It is possible, however, to create a container on the remote host that acts as the seed for a completely new fabric, separate from the current one. To create a new fabric on the remote host, invoke the
fabric:container-create-ssh command with the --ensemble-server flag, which makes the newly created container (or containers) a Fuse Server. The newly created Fuse Server on the remote host does not join the current ensemble: it belongs to an independent ensemble (a new fabric).
Arguments
Table 7.11, “fabric:container-create-ssh Arguments” describes the command's arguments.
| Argument | Interpretation |
|---|---|
--help | Displays the online help for this command |
--host | (Required) Host name to SSH into. |
--port | The IP port number for the SSH connection. Default is 22. |
--min-port | The minimum port number of the allowed IP port range. Default is 0. |
--max-port | The maximum port number of the aollowed IP port range. Default is 65535. |
--path | Path on the remote filesystem where the container is to be installed. |
--user | (Required) User name for login. |
--password | Password for login. If the password is omitted, private key authentication is used instead. |
--new-user |
Used in combination with the
--ensemble-server option to ensure that at least one user exists in the JAAS realm of the Zookeeper login module for the new fabric (otherwise it would be impossible to connect to the newly created Fabric Server).
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 and the --ensemble-server option to specify the new user's password. No default value. |
--new-user-role | Used in combination with the --new-user option and the --ensemble-server to specify the new user's role. Default is admin. |
--private-key | Specifies the path to the private key on the local file system. The default is ~/.ssh/id_rsa on *NIX platforms or C:\Documents and Settings\UserName\.ssh\id_rsa on Windows. |
--pass-phrase | The pass phrase of the key, if private key authentication is used and the private key is encrypted. |
--ssh-retries | Maximum number or times to retry SSH connection. |
--proxy-uri | URL of the Maven proxy server used to download the container runtime. |
--ensemble-server | Creates a container on the remote host that acts as the seed for a completely new fabric, separate from the container that invokes the command. The newly created container is a Fuse server on the remote host and does not join the current ensemble. The new container belongs to an independent ensemble (a new fabric). |
--profile | A list of profile IDs to associate with the new container. |
--version | Specifies the version of the new container (the version must be created in advance using fabric:version-create). Defaults to the current default version (use version-list to find the current default). |
-b, --bind-address | Specifies the default bind address. |
--datastore-type | Specifies the datastore type. |
--datastore-option | Options to pass to the container's datastore. To specify multiple options, use this flag multiple times. |
--zookeeper-password | Used in combination with the --ensemble-server option. If creating an ensemble server, specifies the Zookeeper password to use (if not specified, a password is generated automatically). |
--jvm-opts | Specify options to pass to the container's JVM. |
--resolver | Specifies how the container will report its address to other containers. Valid values are localip, localhostname, publicip, publichostname, manualip. For more information see Section 7.20, “fabric:container-resolver-set”. |
-m, --manual-ip | The IP address to use, when using the manualip resolver. Used in combination with the --resolver option. |
--env | Sets an environment variable. To specify multiple environment variables, use this flag multiple times. |
--with-admin-access | Indicates that the target user has administrative access (password-less sudo). When this option is specified, Fabric will attempt to install any missing dependencies on the target host. |
--disable-distribution-upload | Flag to disable uploading the AMQ distribution. When used, the target host downloads the distribution through Maven instead. |
Name | (Required) The name of the container to create. When creating multiple containers, it serves as a prefix. |
Number | The number of containers that should be created. |
