Make sure that domino-cli.py is in +x mode. + +2. Change directory to where domino-cli.py, DominoClient.py and DominoServer.py are located or include file path in the PATH environment variable. + +3. Start the Domino Server: + +.. code-block:: bash + + ./DominoServer.py --log=debug + +4. Start the Domino Client: + +.. code-block:: bash + + ./DominoClient.py -p <portnumber> --cliport <cli-portnumber> --log=debug + +Note1: The default log level is WARNING and omitting --log option will lead to minimal/no logging on the console + +Note2: domino_conf.py file includes most of the default values + +* Registration Command + +Command line input: + +.. code-block:: bash + + ./domino-cli.py <cli-portnumber> register + +This message has the following fields that are automatically filled in. + +.. code-block:: bash + + Message Type (= REGISTER) + DESIRED UDID (= if not allocated, this will be assigned as Unique Domino ID) + Sequence Number (=incremented after each RPC call) + IP ADDR (= IP address of DOMINO Client to be used by DOMINO Server for future RPC Calls to this client) + TCP PORT (= TCP port of DOMINO Client to be used by DOMINO Server for future RPC Calls to this client) + Supported Templates (= Null, this field not used currently) + +* Heart Beat Command + +Command line input: + +.. code-block:: bash + + ./domino-cli.py <cli-portnumber> heartbeat + +This message has the following fields that are automatically filled in. + +.. code-block:: bash + + Message Type (= HEART_BEAT) + UDID (= Unique Domino ID assigned during registration) + Sequence Number (=incremented after each RPC call) + +* Label and Template Type Subscription Command + +.. code-block:: bash + + ./domino-cli.py <cli-portnumber> subscribe -l <labelname> -t <templatetype> + +Note that -l can be substituted by --label and -t can be substituted by --ttype. + +More than one label or template type can be subscribed within the same command line as comma separated labels or template types + +.. code-block:: bash + + ./domino-cli.py <cli-portnumber> subscribe -l <label1>,<label2>,<labeln> -t <ttype1>,<ttype2>,<ttypen> + +To subscribe more than one label or template type, one can also repeat the options -l and -t, e.g.: + +.. code-block:: bash + + ./domino-cli.py <cli-portnumber> subscribe -l <label1> -l <label2> -l <labeln> -t <ttype1> -t <ttype2> -t <ttypen> + +It is safe to call subscribe command multiple times with duplicate labels. + +This message has the following fields that are automatically filled in. + +.. code-block:: bash + + Message Type (= SUBSCRIBE) + UDID (= Unique Domino ID assigned during registration) + Sequence Number (=incremented after each RPC call) + Template Operation (= APPEND) + Label Operation (= APPEND) + +The following fields are filled in based on arguments passed on via -l/--label and -t/--ttype flags + +Subscribe RPC also supports options for label using + --lop=APPEND/DELETE/OVERWRITE +and for supported template types using + --top=APPEND/DELETE/OVERWRITE. +When unspecified, the default is APPEND. +DELETE deletes existing labels (template types) specified in the current call via key -l/--label (-t/--ttype). +OVERWRITE removes the current set of labels (template types) and sets it to the new set of values passed in the same RPC call. + +By default, no translation service is provided.

The following command can be used to update the service template for an existing Template Unique ID (TUID): + +.. code-block:: bash + + ./domino-cli.py <cli-portnumber> publish -t <toscafile> -k <TUID> + +Note that -k can be substituted with --tuid. When Domino Server receives this command, it verifies whether +the client previously published the provided TUID. If such TUID does not exist, then Domino Server returns +FAILED response back to the client. If such TUID exists, Domino Server recomputes which resources are +mapped onto which domains and updates each domain with the new VNF and NS descriptors. If a previously +utilized domain is no longer targeted, it is updated with a null descriptor. + +* Template Listing Command + +.. code-block:: bash + + ./domino-cli.py <cli-portnumber> list-tuids + +Queries all the Template Unique IDs (TUIDs) published by the Domino Client from the Domino Server. + +Interactive CLI mode +-------------------- + +To enter this mode, start Domino Client with interactive console option set as true, i.e., --iac=true: + +.. code-block:: bash + + ./DominoClient -p <portnumber> --iax=true --log=DEBUG + +The rest of the API calls are the same as in the case of using domino-cli.py except that at the prompt there is no need to write "domino-cli.py <cli-portnumber>, e.g.,: + +.. code-block:: bash + + >>register + >>heartbeat + >>subscribe -l <label1> -t <ttype1> + >>publish -t <toscafile> + +The interactive CLI mode is mainly supported for manual testing. |
