编写 fabric 网络连接配置文件

该连接配置文件要根据我们的网络拓扑结构进行编写。

      }
    }
  }
}

编写

config.json

配置文件

这个配置文件用来指定 fabric 网络连接配置文件的路径。

{
        "network-configs": {
                "prod-network": {
                        "name": "Prod Network",
                        "profile": "./connection-profile/org1ProdNetworkConnection.json"
                }
        },
        "license": "Apache-2.0"
}

编写 docker-compose 文件


docker-compose-explorer.yaml

:

version: '2.0'


volumes:
    pgdata:
    walletstore:

services:

    explorerdb.mynetwork.com:
        image: hyperledger/explorer-db:latest
        container_name: explorerdb.mynetwork.com
        hostname: explorerdb.mynetwork.com
        ports:
            - 5432:5432
        environment:
            - DATABASE_DATABASE=fabricexplorer
            - DATABASE_USERNAME=hppoc
            - DATABASE_PASSWORD=password
        healthcheck:
            test: "pg_isready -h localhost -p 5432 -q -U postgres"
            interval: 30s
            timeout: 10s
            retries: 5
        volumes:
            - pgdata:/var/lib/postgresql/data


    explorer.mynetwork.com:
        image: hyperledger/explorer:latest
        container_name: explorer.mynetwork.com
        hostname: explorer.mynetwork.com
        ports:
            - 9090:8080
        extra_hosts:
            - "explorerdb.mynetwork.com:192.168.0.105"
            - "orderer0.example.com:192.168.0.105"
            - "orderer1.example.com:192.168.0.105"
            - "orderer2.example.com:192.168.0.105"
            - "peer0.org1.example.com:192.168.0.109"
            - "peer1.org1.example.com:192.168.0.109"
            - "peer0.org2.example.com:192.168.0.110"
            - "peer1.org2.example.com:192.168.0.110"
        environment:
            - DATABASE_HOST=explorerdb.mynetwork.com
            - DATABASE_DATABASE=fabricexplorer
            - DATABASE_USERNAME=hppoc
            - DATABASE_PASSWD=password
            - LOG_LEVEL_APP=debug
            - LOG_LEVEL_DB=info
            - LOG_LEVEL_CONSOLE=debug
            - LOG_CONSOLE_STDOUT=true
            - DISCOVERY_AS_LOCALHOST=false
        volumes:
            - ./config.json:/opt/explorer/app/platform/fabric/config.json
            - ./connection-profile:/opt/explorer/app/platform/fabric/connection-profile
            - ../crypto-config:/tmp/crypto
            - walletstore:/opt/explorer/wallet
        depends_on:
            explorerdb.mynetwork.com:
                condition: service_healthy

这些文件都准备好了后目录结构如下：

hyperledger-explorer/
├── config.json
├── connection-profile
│   └── org1ProdNetworkConnection.json
└── docker-compose-explorer.yaml

启动 Hyperledger Explorer：

docker-compose -f docker-compose-explorer.yaml up -d

清理（不删除持久性数据）：

docker-compose -f docker-compose-explorer.yaml down

彻底清理：

docker-compose -f docker-compose-explorer.yaml down -v

启动后访问

http://localhost:9090/
