There was a problem hiding this comment.
FYI: The change in addressing the ca.crt for the $TRUSTSTORE_PATH via
kubectl get configmaps eclipse-hono-example-trust-store
instead of
kubectl get secrets eclipse-hono-kafka-example-keys
means that the Hono chart
example/certs/trusted-certs.pem
instead of
example/certs/ca-cert.pem
is used.
Without this change, mosquitto_pub/sub will return an error:
OpenSSL Error[0]: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed
It seems that the example/certs/root-cert.pem included in example/certs/trusted-certs.pem is needed.

This fixes #3582 .
When connecting to a local Hono instance using the IP obtained from the K8s Service, the hostname verification as part of the TLS connection attempt will not work for the demo certs. Therefore the
--insecureoption has to be added to thecurlandmosquitto_pub/subcommands. Formosquitto_pub/sub, the--insecureoption will disable only the hostname verification. Forcurl, there is no separate command line option for that (equivalent to theCURLOPT_SSL_VERIFYHOSTlibcurl option), hence the need to use--insecure, disabling certificate checking.(There would be an alternative to
curl --insecure, using the parameter--resolve "hono-service-device-registry.hono:28443:${REGISTRY_IP}"andhono-service-device-registry.honoas host in the URL, but this may be a bit confusing.)
