Hyperledger Composer Network Start

The composer network start utility is used to start a specific version of a business network that has been previously installed to a Hyperledger Fabric v1.2 network. Before using this command, read the topic Deploying and Updating Business Networks.

Please Note: You must first install the business network to the Hyperledger Fabric peers by using the composer network install command.

composer network start --networkName <business-network-name> --networkVersion <business-network-version> --networkAdmin <admin-name> --networkAdminEnrollSecret <enroll-secret> --card <peer-admin-card> --file <admin-card-file-name>

Considerations

This command creates a new card file. The connection profile in this card file comes from the card defined in the -c|--card option used to perform the request and the connection profile defines whether an identity in a card should be HSM managed or not. If the card used for the request is not HSM managed (as defined in the connection profle) then the card file created will not be HSM managed. Conversely if the card used for the request is HSM managed then the card file created will also be HSM managed.
