Prerequisites and Considerations

• Important
  This security group configuration is recommended for this tutorial only. Carefully consider security group settings for your desired security posture. For information about the minimum required rules, see Configuring Security Groups for Hyperledger Fabric on Amazon Managed Blockchain.

Step 4: Set Up a Client

• Note
  An AWS CloudFormation template to create a Hyperledger Fabric client is available in amazon-managed-blockchain-client-templates repository on Github. For more information, see the readme.md in that repository. For more information about using AWS CloudFormation, see Getting Started in the AWS CloudFormation User Guide.
• Note
  If you are working with Hyperledger Fabric v1.2 networks, you need to install and build the correct client version, which is available at https://github\.com/hyperledger/fabric\-ca/releases/download/v1\.2\.1/hyperledger\-fabric\-ca\-linux\-amd64\-1\.2\.1\.tar\.gz\.
• Note
  If you are working with Hyperledger Fabric v1.2 networks, use --branch v1.2.0 instead of --branch v1.4.7 in the following commmands.
• Note
  If you are working with Hyperledger Fabric v1.2 networks, use image: hyperledger/fabric-tools:1.2 in the following example instead of image: hyperledger/fabric-tools:1.4. In addition, use CORE_LOGGING_LEVEL=info instead of FABRIC_LOGGING_SPEC=info.

Step 5: Enroll the Member Admin

• Important
  It may take a minute or two after you enroll for you to be able to use your administrator certificate to create a channel with the ordering service.

Step 6: Create a Channel

• Note
  All Hyperledger Fabric networks on Managed Blockchain support a maximum of 8 channels per network, regardless of network edition.

You can also use VI, but before using VI, enter :set paste, press i to enter insert mode, paste the contents, press escape, and then enter :set nopaste before saving.
• Important
  Hyperledger Fabric 1.4 requires that a channel ID contain only lowercase ASCII alphanumeric characters, dots (.), and dashes (-). It must start with a letter, and must be fewer than 250 characters.

Step 8: Invite a Member and Create a Multi-Member Channel
