Cannot start agent, "Something went wrong while opening RTSP: open : no such file or directory"

[UntouchedWagons]

Hi there. I'm trying to deploy K-agent in a K3S cluster and I'm having trouble getting the container to start, I keep getting the error {"level":"error","msg":"Something went wrong while opening RTSP: open : no such file or directory","time":"2023-03-23T21:09:15+01:00"} over and over in the log and I cannot find in your documentation how I'm supposed to add my cameras to the config.json file.

Here is my deployment file:

apiVersion: apps/v1

              "cp",
              "/home/agent/data/config.template.json",
              "/home/agent/data/config/config.json",
            ]

      containers:

Hey @UntouchedWagons, it looks that for some reason your config cannot be read, and so the RTSP stream is not found. Can you SSH into the container and review the config.json file in the container.

It must have been some kind of permissions issue, I've since switched to Longhorn for volume storage and the Kerberos agent starts just fine. My current deployment file:

apiVersion: apps/v1

          persistentVolumeClaim:
            claimName: longhorn-kerberos

      initContainers:
        - name: download-config
          image: kerberos/agent:bbbed49
          volumeMounts:
            - name: kerberos-data
              mountPath: /home/agent/data/config
              subPath: config
          command:
            [
              "cp",
              "/home/agent/data/config.template.json",
              "/home/agent/data/config/config.json",
            ]

      containers:
        - name: agent
          image: kerberos/agent:bbbed49
          volumeMounts:
