Question 268425 in Docker Question posted in
The official documentation can be found here.

Java IBM MQ client MQ.Environment setting hostname to only ip adress not connecting, but setting to "localhost" works. Local docker deployment ibm-mq

I’m using the com.ibm.mq.allclient-9.3.3.1.jar.

I have a java test class, which tests the connection to a local docker IBM MQ container.
I set it up like this:

        openOptions = CMQC.MQOO_INQUIRE | CMQC.MQOO_INPUT_AS_Q_DEF | MQConstants.MQOO_OUTPUT;
        MQEnvironment.hostname = "localhost";
        MQEnvironment.port = 1414;
        MQEnvironment.channel = "DEV.APP.SVRCONN";
        MQEnvironment.properties.put(CMQC.USER_ID_PROPERTY, "app");
        MQEnvironment.properties.put(CMQC.TRANSPORT_PROPERTY, CMQC.TRANSPORT_MQSERIES);

        String queueManagerName = "QM1";
        queueManager = new MQQueueManager(queueManagerName);

This is working fine.

But when I want to connect to it via the IP of the docker container, it is failing:

MQEnvironment.hostname = 172.27.0.2;

Error logs:

Can someone please help me why? And how to fix it?

    Is the queue manager’s listener object configured to listen on the primary ethernet interface rather than the localhost loopback adapter? MQRC 2538 means MQRC_HOST_NOT_AVAILABLE, so this is either a case of the queue manager not listening on the IP in question, or it’s a network configuration error for the container itself.

    localhost will be 127.0.0.1, ie your machine – the docker host, and not the docker container.

    172.27.0.2 will most likely be your docker container, it will be listening on port 1414, but its network will be isolated. Other containers running on the same network will be able to see it, but your machine (docker host) won’t.

    To communicate with the docker container, a port mapping will have been created, so that network traffic directed at port 1414 on the docker host (your machine) is directed to the appropriate network and to the container.

    So you need to substitute localhost with the ip of your machine.
