Chirpstack pulsar integration

ChirpStack (v4) Integrations
1

I have been trying to get the pulsar integration working via docker on my test server, everything seems to work except for the chirpstack-pulsar-integration container itself no matter what it always seems to die with an exit code.

if I add a command to start and load the binary in the compose it tells me that the command doesn’t exist, but it i add it in it tells me it is needed.

I also tried pulling the test container off docker hub, but it also throws the same errors - it also hasn’t been updated for a while so it might still be using v4.6 api?

any ideas?

compose snippet…

services:
  chirpstack-pulsar-integration:

The locally built image doesnt seem to want to work at all.

the command with docker command: -c /configuration/chirpstack-pulsar-integration.toml seems to work only with the docker test image. but the connection seems to drop after a short time.

I also ended up trying to build it locally to try another approach exposing the ports from containers for another test, then it appears to throw connection errors to the running instance.
