Trouble connecting to AMQP adapter in OpenShift

Question

I'm trying to create an MQTT Protocol Gateway for our Hono Cluster running in OpenShift using this template but I am having trouble connecting to the AMQP adapter.

I can connect to the Sandbox AMQP adapter using the CLI (version 2.1.0) but when I try to connect to the instance running in our cluster I get "503 - Temporary unavailable".

I have tried many variants of this command, but I discovered I get the exact same error seemingly no matter what host I call in OpenShift, including hosts not even running in our Hono cluster, and I don't know what that means.

I have verified the cluster installation in so far that all the pods look healthy and I have been able to create tenants and devices and I can send telemetry to the HTTP adapter.

Answer 1

You should omit the https:// prefix from the host name and you will also need to provide a username and password for authenticating to the AMQP adapter using the -u and -p options:

java -jar hono-cli-*-exec.jar amqp -H hono-poc-adapter... -P 5672 -u sensor1@DEFAULT_TENANT -p hono-secret

Answer 2

I have still not been able to connect using the CLI from my local computer, but since the protocol gateway should run in the cluster anyway I deployed a container with the Hono CLI installed and ran the CLI from the pods terminal, which worked.

java -jar hono-cli-*-exec.jar amqp -H hono-adapter-amqp -P 5672 -u TEST_DEVICE@TEST_TENANT -p pwd

"hono-adapter-amqp" in this case is the service name of the amqp-adapter in OpenShift, the IP also worked but the route did not.
