Corda Network Builder
|

|
|
=====================

The Corda Network Builder is a tool for building Corda networks for testing purposes. It leverages Docker and
|
||
|
|
containers to abstract the complexity of managing a distributed network away from the user.
|
||
|
|
|
||
|
|
Currently, the network you build will either be made up of local ``docker`` nodes *or* of nodes spread across Azure
|
||
|
|
containers.
|
||
|
|
|
||
|
|
The Corda Network Builder can be downloaded from
|
||
|
|
https://ci-artifactory.corda.r3cev.com/artifactory/corda-releases/net/corda/corda-network-builder/X.Y-corda/corda-network-builder-X.Y-corda-executable.jar,
|
||
|
|
where ``X`` is the major Corda version and ``Y`` is the minor Corda version.

Prerequisites
|
||
|
|
-------------
|
||
|
|
|
||
|
|
* **Docker:** docker > 17.12.0-ce
|
||
|
|
* **Azure:** authenticated az-cli >= 2.0 (see: https://docs.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest)

Creating the base nodes
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
The network builder uses a set of nodes as the base for all other operations. A node is anything that satisfies
|
||
|
|
the following layout:
|
||
|
|
|
||
|
|
.. sourcecode:: shell
|
||
|
|
|
||
|
|
-
|
||
|
|
-- node.conf
|
||
|
|
-- corda.jar
|
||
|
|
-- cordapps/
|
||
|
|
|
||
|
|
|
||
|
|
An easy way to build a valid set of nodes is by running ``deployNodes``. In this document, we will be using
|
||
|
|
the output of running ``deployNodes`` for the `Example CorDapp <https://github.com/corda/cordapp-example>`_:
|
||
|
|
|
||
|
|
1. ``git clone https://github.com/corda/cordapp-example``
|
||
|
|
2. ``cd cordapp-example``
|
||
|
|
3. ``./gradlew clean deployNodes``
|
||
|
|
|
||
|
|

1. ``cd kotlin-source/build/nodes``
|

2. ``java -jar <path/to/network-builder-jar> -b AZURE -d .``

Interacting with the nodes
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
You can interact with the nodes by SSHing into them on the port that is mapped to 12222. For example, to SSH into the
|
||
|
|
``partya0`` node, you would run:
|
||
|
|
|
||
|
|
.. sourcecode:: shell
|
||
|
|
|
||
|
|
ssh user1@localhost -p 32893
|
||
|
|
Password authentication
|
||
|
|
Password:
|
||
|
|
|
||
|
|
|
||
|
|
Welcome to the Corda interactive shell.
|
||
|
|
Useful commands include 'help' to see what is available, and 'bye' to shut down the node.
|
||
|
|
|
||
|
|
>>> run networkMapSnapshot
|

Adding additional nodes
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
It is possible to add additional nodes to the network by reusing the nodes you built earlier. For example, to add a
|
||
|
|
node by reusing the existing ``PartyA`` node, you would run:
|
||
|
|
|
||
|
|
``java -jar <network-builder-jar> --add "PartyA=O=PartyZ,L=London,C=GB"``
|
||
|
|
|
||
|
|
To confirm the node has been started correctly, run the following in the previously connected SSH session:
|
||
|
|
|
||
|
|
.. sourcecode:: shell
|
||
|
|
|
||
|
|

|
||
|
|
{ "addresses" : [ "notary0:10020" ], "legalIdentitiesAndCerts" : [ "O=Notary, L=London, C=GB" ], "platformVersion" : 3, "serial" : 1532701305115 },
|
||
|
|
{ "addresses" : [ "partyc0:10020" ], "legalIdentitiesAndCerts" : [ "O=PartyC, L=Paris, C=FR" ], "platformVersion" : 3, "serial" : 1532701331608 },
|
||
|
|
{ "addresses" : [ "partyb0:10020" ], "legalIdentitiesAndCerts" : [ "O=PartyB, L=New York, C=US" ], "platformVersion" : 3, "serial" : 1532701330118 },
|
||
|
|
{ "addresses" : [ "partya1:10020" ], "legalIdentitiesAndCerts" : [ "O=PartyZ, L=London, C=GB" ], "platformVersion" : 3, "serial" : 1532701630861 }

Building a network in Graphical User Mode
|
||
|
|
-----------------------------------------
|
||
|
|
|
||
|
|
The Corda Network Builder also provides a GUI for when automated interactions are not required. To launch it, run
|
||
|
|
``java -jar <path/to/network-builder-jar> -g``.
|
||
|
|
|
||
|
|
Starting the nodes
|
||
|
|
^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
1. Click ``Open nodes ...`` and select the folder where you built your nodes in :ref:`creating_the_base_nodes` and
|
||
|
|
click ``Open``
|
||
|
|
2. Select ``Local Docker`` or ``Azure``
|
||
|
|
3. Click ``Build``
|
||
|
|
|
||
|
|
.. note:: The Azure configuration is handled by the az-cli utility. See the :ref:`pre-requisites`.
|
||
|
|
|
||
|
|
All the nodes should eventually move to a ``Status`` of ``INSTANTIATED``. If you run ``docker ps`` from the terminal to
|
||
|
|
see the running containers, the following output should be displayed:
|
||
|
|
|
||

Interacting with the nodes
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^

|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
It is possible to add additional nodes to the network by reusing the nodes you built earlier. For example, to add a
|
||
|
|
node by reusing the existing ``PartyA`` node, you would:
|
||
|
|
|
||
|
|
1. Select ``partya`` in the dropdown
|
||
|
|
2. Click ``Add Instance``
|
||
|
|
3. Specify the new node's X500 name and click ``OK``
|
||
|
|
|
||
|
|
If you click on ``partya`` in the pane, you should see an additional instance listed in the sidebar. To confirm the
|
||
|
|
node has been started correctly, run the following in the previously connected SSH session:
|
||
|
|
|

|
||

]
|
||
|
|
|
||
|
|
Shutting down the nodes
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
Run ``docker kill $(docker ps -q)`` to kill all running Docker processes.
|
