Hyperledger Fabric 1.0 实例简析 第一课 network_setup.sh分析

以fabric-samples/balance-transfer例子：

1. 具体流程

fabric/examples/e2e_cli

目录下存有文件

network_setup.sh

用于一键部署环境并测试chaincode示例代码。其中包括两个部分，一个是利用generateArtifacts.sh脚本文件配置组织关系和颁发证书，另一个是docker-compose-cli.yaml用于根据配置启动集群并测试chaincode的示例代码。

2. generateArtifacts.sh脚本文件

包含三个函数：generateCerts：使用cryptogen工具根据

crypto-config.yaml

来生成证书。
replacePrivateKey：将docker-compose-e2e-template.yaml文档中的ca私钥替换成具体的私钥。（本例中未使用）
generateChannelArtifacts：使用configtxgen工具根据

configtx.yaml

文件来生成

orderer genesis block

、

channel configuration transaction

、

anchor peer update

。

crypto-config.yaml

的具体内容如下：

# ---------------------------------------------------------------------------
# "OrdererOrgs" - Definition of organizations managing orderer nodes
# ---------------------------------------------------------------------------
OrdererOrgs:
# ---------------------------------------------------------------------------
# Orderer
# ---------------------------------------------------------------------------
- Name: Orderer
Domain: example.com
# ---------------------------------------------------------------------------
# "Specs" - See PeerOrgs below for complete description
# ---------------------------------------------------------------------------
Specs:
- Hostname: orderer
# ---------------------------------------------------------------------------
# "PeerOrgs" - Definition of organizations managing peer nodes
# ---------------------------------------------------------------------------
PeerOrgs:
# ---------------------------------------------------------------------------
# Org1
# ---------------------------------------------------------------------------
- Name: Org1
Domain: org1.example.com
# ---------------------------------------------------------------------------
# "Specs"
# ---------------------------------------------------------------------------
# Uncomment this section to enable the explicit definition of hosts in your
# configuration.  Most users will want to use Template, below
#
# Specs is an array of Spec entries.  Each Spec entry consists of two fields:
#   - Hostname:   (Required) The desired hostname, sans the domain.
#   - CommonName: (Optional) Specifies the template or explicit override for
#                 the CN.  By default, this is the template:
#
#                              "{{.Hostname}}.{{.Domain}}"
#
#                 which obtains its values from the Spec.Hostname and
#                 Org.Domain, respectively.
# ---------------------------------------------------------------------------
# Specs:
#   - Hostname: foo # implicitly "foo.org1.example.com"
#     CommonName: foo27.org5.example.com # overrides Hostname-based FQDN set above
#   - Hostname: bar
#   - Hostname: baz
# ---------------------------------------------------------------------------
# "Template"
# ---------------------------------------------------------------------------
# Allows for the definition of 1 or more hosts that are created sequentially
# from a template. By default, this looks like "peer%d" from 0 to Count-1.
# You may override the number of nodes (Count), the starting index (Start)
# or the template used to construct the name (Hostname).
#
# Note: Template and Specs are not mutually exclusive.  You may define both
# sections and the aggregate nodes will be created for you.  Take care with
# name collisions
# ---------------------------------------------------------------------------
Template:
Count: 2
# Start: 5
# Hostname: {{.Prefix}}{{.Index}} # default
# ---------------------------------------------------------------------------
# "Users"
# ---------------------------------------------------------------------------
# Count: The number of user accounts _in addition_ to Admin
# ---------------------------------------------------------------------------
Users:
Count: 1
# ---------------------------------------------------------------------------
# Org2: See "Org1" for full specification
# ---------------------------------------------------------------------------
- Name: Org2
Domain: org2.example.com
Template:
Count: 2
Users:
Count: 1

3. docker-compose-cli.yaml文件

根据组织关系启动docker集群，并在cli容器中执行command命令运行

./scripts/script.sh

脚本文件。

./scripts/script.sh

脚本包含以下函数：createChannel：创建channel。
joinChannel：将每个peer节点加入channel。
updateAnchorPeers
installChaincode：部署chaincode。
instantiateChaincode：初始化chaincode，并设置背书策略。
chaincodeQuery
chaincodeInvoke
