|
||||
* Gradle build file to show how to install your Cordapp configuration
|
||||
* A flow that consumes the Cordapp configuration
|
||||
|
||||
## Usage
|
||||
To run from the command line in Unix:
|
||||
|
||||
To run the sample you must first build it from the project root with;
|
||||
1. Run ``./gradlew samples:cordapp-configuration:deployNodes`` to create a set of configs and installs under
|
||||
``samples/cordapp-configuration/build/nodes``
|
||||
2. Run ``./samples/cordapp-configuration/build/nodes/runnodes`` to open up three new terminals with the three nodes
|
||||
3. At the shell prompt for Bank A or Bank B run ``start net.corda.configsample.GetStringConfigFlow configKey: someStringValue``.
|
||||
This will start the flow and read the `someStringValue` CorDapp config.
|
||||
|
||||
./gradlew deployNodes
|
||||
To run from the command line in Windows:
|
||||
|
||||
This will deploy the node with the configuration installed.
|
||||
The relevant section is the ``deployNodes`` task.
|
||||
|
||||
## Running
|
||||
|
||||
* Windows: `build\nodes\runnodes`
|
||||
* Mac/Linux: `./build/nodes/runnodes`
|
||||
|
||||
Once the nodes have started up and show a prompt you can now run your flow.
|
||||
1. Run ``gradlew samples:cordapp-configuration:deployNodes`` to create a set of configs and installs under
|
||||
``samples\cordapp-configuration\build\nodes``
|
||||
2. Run ``samples\cordapp-configuration\build\nodes\runnodes`` to open up three new terminals with the three nodes
|
||||
3. At the shell prompt for Bank A or Bank B run ``start net.corda.configsample.GetStringConfigFlow configKey: someStringValue``.
|
||||
This will start the flow and read the `someStringValue` CorDapp config.
