Deploying a Business Network

A business network is deployed using the composer network deploy command.

Procedure

1. Before deploying a business network, a Business Network Definition is needed as a zip file with the following structure:

   BusinessNetworkArchive.zip
   ├── lib
   │   └── mozart.cto.js
   ├── models
   │   └── mozart.cto
   └── package.json
   

-   **lib** contains all of the transactions processor functions
-   **models** contains all of the model files written in the [CTO Language](../reference/cto_language.html).
-   **package.json** is required, and is used to create the [Business Network Definition](../reference/businessnetworkdefinition.html)'s identifier

You can use the `composer archive` command to create an archive with the correct format.

**NOTE**: *Do not zip a a folder containing **lib**, **models**, and **package.json** to create an Business Network Archive, zip the contents themselves*

1. Start Hyperledger Fabric Peer and Membership Service

2. Create a Connection Profile or do not use -p and allow Fabric Composer to create a Default Connection Profile for you.

3. Enter the command on a single line. For example:

   composer network deploy -a <BusinessNetworkDefinition>.zip -i <Your EnrollmentID>

4. Enter your Enrollment Secret when prompted.

   prompt: What is the enrollment secret of the user?:

5. When you see

   Command completed successfully.
