Hyperledger Fabric explorer区块链浏览器搭建

https://github.com/hyperledger-labs/blockchain-explorer
官方浏览器的github地址
根据文档，采用docker容器的方法搭建explorer。

首先创建explorer的项目，

mkdir explorer

根据官方提供的文件，需要创建的目录结构如下：

这是官网提供的模板

wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/main/examples/net1/config.json
wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/main/examples/net1/connection-profile/test-network.json -P connection-profile
wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/main/docker-compose.yaml

配置文件

这里的organizations就是你搭建区块链网络的证书配置文件crypto-config文件，因为之前的网络创建的是两个组织，所以配置了两个json文件
这是组织一的network的json文件配置

{
	"name": "org1-network",
	"version": "1.0.0",
	"client": {
		"tlsEnable": true,
		"adminCredential": {
			"id": "exploreradmin",
			"password": "exploreradminpw"
		},
		"enableAuthentication": true,
		"organization": "Org1MSP",
		"connection": {
			"timeout": {
				"peer": {
					"endorser": "300"
				},
				"orderer": "300"
			}
		}
	},
	"channels": {
		"mychannel": {
			"peers": {
				"peer0.org1.example.com": {}
			}
		}
	},
	"organizations": {
		"Org1MSP": {
			"mspid": "Org1MSP",
			"adminPrivateKey": {
				"path": "/tmp/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp/keystore/priv_sk"
			},
			"peers": ["peer0.org1.example.com"],
			"signedCert": {
				"path": "/tmp/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp/signcerts/[email protected]"
			}
		}
	},
	"peers": {
		"peer0.org1.example.com": {
			"tlsCACerts": {
				"path": "/tmp/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt"
			},
			"url": "grpcs://peer0.org1.example.com:7051"
		}
	}
}

这是组织二的network的json文件配置

{
	"name": "org2-network",
	"version": "1.0.0",
	"client": {
		"tlsEnable": true,
		"adminCredential": {
			"id": "exploreradmin",//登录浏览器的id
			"password": "exploreradminpw"//密码
		},
		"enableAuthentication": true,
		"organization": "Org2MSP",
		"connection": {
			"timeout": {
				"peer": {
					"endorser": "300"
				},
				"orderer": "300"
			}
		}
	},
	"channels": {
		"mychannel": {
			"peers": {
				"peer0.org2.example.com": {}
			}
		}
	},
	"organizations": {
		"Org2MSP": {
			"mspid": "Org2MSP",
			"adminPrivateKey": {
				"path": "/tmp/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp/keystore/priv_sk"
			},
			"peers": ["peer0.org2.example.com"],
			"signedCert": {
				"path": "/tmp/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp/signcerts/[email protected]"
			}
		}
	},
	"peers": {
		"peer0.org2.example.com": {
			"tlsCACerts": {
				"path": "/tmp/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt"
			},
			"url": "grpcs://peer0.org2.example.com:9051"
		}
	}
}

然后配置config.json文件

{
	"network-configs": {
		"org1-network": {
			"name": "org1-network",
			"profile": "./connection-profile/org1-network.json"
		},
        "org2-network": {
			"name": "org2-network",
			"profile": "./connection-profile/org2-network.json"
		}
	},
	"license": "Apache-2.0"
}

最后配置docker-compose.yaml文件

# SPDX-License-Identifier: Apache-2.0

volumes:
  pgdata:
  walletstore:

networks:
  mynetwork.com:
    name: fixtures_test

      - PORT=${PORT:-8080}
    volumes:
      - ./config.json:/opt/explorer/app/platform/fabric/config.json
      - ./connection-profile:/opt/explorer/app/platform/fabric/connection-profile
      - ./organizations:/tmp/crypto
      - walletstore:/opt/explorer/wallet
    ports:
      - 8080:8080
    depends_on:
      explorerdb.mynetwork.com:
        condition: service_healthy
    networks:
      - mynetwork.com

开始运行docker-compose.yaml文件
创建explorer、explorerdb两个容器

通过浏览器访问explorer：
127.0.0.1：8080，登录区块链浏览器。
