无法使用容器将消息放入 ibm mq

Question

I have two docker containers which I'm building using docker-compose. One of which initializes the ibm mqs and another is the one exposes rest end points(using SpringBoot project) to send message to the ibm mq which were set up by first container. When I get the docker-compose up I am getting the below error

mock-service_1  | 2020-01-29 08:07:52.928 ERROR 1 --- [nio-7090-exec-2] c.j.ids.controller.AcarsController       : JMSWMQ0018: Failed to connect to queue manager 'QM1' with connection mode 'Client' and host name 'localhost(1414)'.
acars-mock-service_1  | com.ibm.msg.client.jms.DetailedIllegalStateException: JMSWMQ0018: Failed to connect to queue manager 'QM1' with connection mode 'Client' and host name 'localhost(1414)'.

mock-service_1  |         at com.ibm.msg.client.wmq.common.internal.Reason.createException(Reason.java:203)

I'm able to put the messages in the same queue if I run the SpringBoot application locally from my IDE without any error. Not sure what is the issue using separate containers. My DockerFile looks like this

FROM ibmcom/mq
USER root
RUN useradd ibm-mq -G mqm && \
    echo ibm-mq:passw0rd | chpasswd
USER mqm
COPY config.mqsc /etc/mqm/

EXPOSE 9443 1414

And config.mqsc

ALTER QMGR CHLAUTH(DISABLED)

docker-compose.yml

version: '3.3'

Answer 1

Localhost inside your spring container, is your spring container. Instead of setting the host to localhost for your MQ Connection you need your container's / host ip.

How you do it depends on your host's platform, but it will be something like host.docker.internal
