Answer 1

To find the channel name:

• shell into the container
• set the environment by running setmqenv See https://www.ibm.com/docs/en/ibm-mq/latest?topic=reference-setmqenv-set-mq-environment
• run runmqsc
• In the runmqsc prompt run display channel (*) See https://www.ibm.com/docs/en/ibm-mq/latest?topic=reference-display-channel-display-channel-definition

Alternatively, you could just log into the MQ Console on https://localhost:9443/ibmmq/console and list the system channels.

If you are using the IBM MQ Advanced for Developers image from icr.io/ibm-messaging/mq:latest then the channels DEV.APP.SVRCONN and DEV.ADMIN.SVRCONN will have been created for you. Apps will normally use DEV.APP.SVRCONN

If you have built the image locally based on instructions from https://github.com/ibm-messaging/mq-container/blob/master/docs/building.md then you need to have run make build-devserver. If you ran make build-advancedserver then the default DEV channels will not have been created.
