docker 网络关闭或启动失败的原因是：有活动端点

解决方法：

# 查找网络对应的活跃容器信息
docker network inspect [<id> or <name>]

# 强制断开连接
docker network disconnect -f [<networkID> or <networkName>] [<endpointName> or <endpointId>]

# 删除无用的网络（其他）
docker network prune

操作示例如下：
1.错误信息

Removing network quorum-test-network_quorum-dev-quickstart
ERROR: network quorum-test-network_quorum-dev-quickstart id db34e6ce28c091a0409e8fb4b470c8ebbfebba9061878728aa4b85c937f0a56c has active endpoints
No stopped containers

2. 查找活跃容器的id

[root@peer0 quorum-test-network]# docker network inspect quorum-test-network_quorum-dev-quickstart

    {

            ]
        },

            "com.docker.compose.version": "1.25.0"
        }
    }
]

3. 强制断开连接

[root@peer0 quorum-test-network]# docker network disconnect -f quorum-test-network_quorum-dev-quickstart quorum-test-network_validator4_1
