Couchdb容器已启动并正在运行。

我曾尝试在d GODEBUG=netdns=go中添加ocker-compose.yml，但没有运气。

我在centos7服务器上使用fabric 1.4.4。

我为此挣扎了数周，但无济于事。

代码docker-compose.yml

您有一个干扰网络的代理。关键是此消息

panic: Error initializing ledger provider: unable to connect to CouchDB, check the hostname and port: error unmarshalling json data: invalid character '<' looking for beginning of value

[当对等方尝试连接到它认为是沙发数据库的网络时，它实际上将连接到代理，该代理将返回某种HTML响应。
