Hyperledger Composer Network Start

The composer network start utility is used to deploy a business network archive from local disk to a Hyperledger Fabric v1.0 network. Before using this command, read the topic Deploying and Updating Business Networks.

Please Note: You must first install the Hyperledger Composer runtime to the Hyperledger Fabric peers by using the composer runtime install command. The business network name specified in the composer runtime install command must be the same as the business network name specified in the composer network start command.

composer network start -a <business-network-archive> -A <admin-name> -S adminpw -c <business-network-card> -f <name-of-admin-card>

Hyperledger Fabric Endorsement Policies

The --option, -o option and the --optionsFile, -O option allow connection specific information to be sent. Hyperledger Fabric endorsement policies can be sent using the -o and -O options in several ways.

Using the -o option, the endorsement policy can be sent as a single-line JSON string as follows:
```
composer network start -o endorsementPolicy='{"identities": [.... }'
```
Using the -o option, the endorsement policy can be sent as a file path as follows:
```
composer network start -o endorsementPolicyFile=/path/to/file/endorsementPolicy.json
```
In this case, the endorsement policy file should follow this format:
```
{"identities":[...],
    "policy": {...}}
```

Using the -O option, the endorsement policy can be sent as a file path as follows:

composer network start -O /path/to/file/options.json

In this case, the options file should follow this format:

        {"endorsementPolicy": {"Identities": [...].
            "policy: {...}"
          },
          "someOtherOption": "A Value"
        }
