我想使用 docker-compose 在服务器上启动IBM MQ server和Python "pymqi" client连接。

为此，我编写了三个 Docker 容器cpython：pymqi和application.
application是基于pymqi自身的cpython（以分离关注点）。

我不断得到pymqi.MQMIError: MQI Error. Comp: 2, Reason 2195: FAILED: MQRC_UNEXPECTED_ERROR。

我已经调查过/var/mqm/qmgrs/QM1/errors/（/var/mqm/errors/如T.Rob所建议的）我认为pymqi容器中有问题但找不到什么。最令人沮丧的部分是Docker 客户端示例就像一个魅力！

下面使用的源代码（我的仓库中提供了沙箱）
