    ./gradlew network-management:capsule:buildDoormanJAR

The built file will appear in:

network-management/capsule/build/libs/doorman-<version>.jar

HSM signing server

The built file will appear in:

network-management/capsule-hsm/build/libs/hsm-<version>.jar

The binaries can also be obtained from artifactory after deployment in TeamCity.

To run the HSM signing server:

cd network-management
java -jar capsule-hsm/build/libs/hsm-<version>.jar --config-file hsm.conf

For a list of options the HSM signing server takes, run with the --help option:

java -jar capsule-hsm/build/libs/hsm-<version>.jar --help

The built file will appear in

network-management/capsule-hsm-cert-generator/build/libs/hsm-cert-generator-<VERSION>.jar

#Configuring network management service

Local signing

When keystorePath is provided in the config file, a signer will be created to handle all the signing periodically using the CA keys in the provided keystore.

The network management service can be started without a signer, the signing will be delegated to external process (e.g. HSM) connecting to the same database, the server will poll the database periodically for newly signed data and update the statuses accordingly.

Additional configuration needed for local signer:

#For local signing
rootStorePath = ${basedir}"/certificates/rootstore.jks"
keystorePath = ${basedir}"/certificates/caKeystore.jks"
keystorePassword = "password"
caPrivateKeyPassword = "password"

Doorman Service

Doorman service can be started with the following options :

JIRA

The doorman service can use JIRA to manage the certificate signing request approval workflow. This can be turned on by providing JIRA connection configuration in the config file.

doormanConfig {
    jiraConfig {
      address = "https://doorman-jira-host.com/"
      projectCode = "TD"
      username = "username"
      password = "password"
    }
    .
    .
    .
}

JIRA project configuration

• The JIRA project should setup as "Business Project" with "Task" workflow.
• Custom text field input "Request ID", and "Reject Reason" should be created in JIRA, doorman will exit with error without these custom fields.

Auto approval

When approveAll is set to true, the doorman will approve all requests on receive. (*This should only be enabled in a test environment)

Network map service

Network map service can be enabled by providing the following config:

networkMapConfig {
  cacheTimeout = 600000
  signInterval = 10000
}

cacheTimeout(ms) indicates how often the network map should poll the database for a newly signed network map. This is also added to the HTTP response header to set the node's network map update frequency.
signInterval(ms) this is only relevant when local signer is enabled. The signer poll the database according to the signInterval, and create a new network map if the collection of node info hashes is different from the current network map.

##Example config file

basedir = "."
host = localhost
port = 0

#For local signing
rootStorePath = ${basedir}"/certificates/rootstore.jks"
keystorePath = ${basedir}"/certificates/caKeystore.jks"
keystorePassword = "password"
caPrivateKeyPassword = "password"

# Database config
dataSourceProperties {
  dataSourceClassName = org.h2.jdbcx.JdbcDataSource
  "dataSource.url" = "jdbc:h2:file:"${basedir}"/persistence;DB_CLOSE_ON_EXIT=FALSE;LOCK_TIMEOUT=10000;WRITE_DELAY=0;AUTO_SERVER_PORT="${h2port}
  "dataSource.user" = sa
  "dataSource.password" = ""
}
h2port = 0

# Doorman config
# Comment out this section if running without doorman service
doormanConfig {
  approveInterval = 10000
  approveAll = false
  jiraConfig {
    address = "https://doorman-jira-host.com/"
    projectCode = "TD"
    username = "username"
    password = "password"
  }
}

# Network map config
# Comment out this section if running without network map service
networkMapConfig {
  cacheTimeout = 600000
  signInterval = 10000
}

Running the network

1. Create keystore for local signer

If local signer is enabled, the server will look for key stores in the certificate folder on start up. The key stores can be created using --mode flag.

java -jar doorman-<version>.jar --mode ROOT_KEYGEN

and

java -jar doorman-<version>.jar --mode CA_KEYGEN

A trust store file containing the root trust certificate will be produced in the location distribute-nodes / truststore.jks (relative to rootStorePath). truststore.jks must be copied to the certificates directory of each node before they attempt to register. The trust store password is trustpass. A trust store containing the root certificate will be created in the location distribute-nodes / network-root-truststore.jks (relative to rootStorePath). The trust store's password can be set using command line argument --trust-store-password, or the doorman's keygen utility will ask for password input if trust store password is not provided using this flag. Path to the network root trust store and password must be provided to corda node via command line arguments before they attempt to register.

2. Start Doorman service for notary registration

Start the network management server with the doorman service for initial bootstrapping. Network map service (networkMapConfig) should be disabled at this point. Comment out network map config in the config file and start the server by running :

java -jar doorman-<version>.jar

3. Create notary node and register with the doorman

After the doorman service is started, start the notary node for the initial-registration process.

4. Generate node info files for notary nodes

Once notary nodes are registered, run the notary nodes with the just-generate-node-info flag. This will generate the node info files, which then should be referenced in the network parameters configuration.

5. Add notary identities to the network parameters

The network parameters should contain reference to the notaries node info files. Example network parameters file:

  notaries : [{
      notaryNodeInfoFile: "/Path/To/NodeInfo/File1"
      validating: true
  }, {
      notaryNodeInfoFile: "/Path/To/NodeInfo/File2"
      validating: false
  }]
  minimumPlatformVersion = 1
  maxMessageSize = 10485760
  maxTransactionSize = 40000

Save the parameters to network-parameters.conf

6. Load initial network parameters file for network map service

A network parameters file is required to start the network map service for the first time. The initial network parameters file can be loaded using the --update-network-parameters flag. We can now restart the network management server with both doorman and network map service.

java -jar doorman-<version>.jar --update-network-parameters network-parameters.conf
