Helm charts for IoT Agent JSON with more recent versions (e.g. >= 1.19) #220
Description
Hi, we are currently trying to deploy the FIWARE components in our Kubernetes cluster utilitizing the most recent versions of the components. However, using the helm charts for the IoT Agent JSON, we run into the following issue: Since the helm charts were created for version 1.14, the IoT Agent comes with a discovery for the mongoDB - and with a hint that this mechanism would be depracated in the future. Now, when trying to deploy the IoT Agent with a newer version, e.g. 1.19 or the most recent 2.4.2, this mechanism seems not be integrated any longer, which results in the IoT Agent not connecting properly to the mongoDB. We are using mongoDB 6.0.9 from bitnami.
In the values.yaml we specified the mongoDB host name as "mongodb-headless.default.svc.cluster.local". So, we are wondering how the new mechanism is currently working and if there are any more recent helm charts available to deploy the IoT Agent.
You can find the error log from the IoT Agent below:
