Unable to deploy Fiware Orion using helm chart

[Pooja Pathak]

I am trying to deploy orion latest version using helm chart: https://github.com/FIWARE/helm-charts/tree/main/charts/orion. For this, I have created a pod of mongo:3.6 and updated image and db details in values.yaml file of orion as:

...
  image:
    # -- orion image name
    #ref: https://hub.docker.com/r/fiware/orion/
    # ref: https://hub.docker.com/r/fiware/orion-ld
    #repository: fiware/orion-ld
    repository: fiware/orion
    # -- tag of the image to be used
    tag: latest
    # -- specification of the image pull policy
    pullPolicy: IfNotPresent
...
  db:
    # -- configuration of the mongo-db hosts. if multiple hosts are inserted, its assumed that mongo is running as a replica set
    hosts: [mongo]
    # - mongodb
    # -- the db to use. if running in multiservice mode, its used as a prefix.
    name: orion
...

after this change, orion pod is created and is in running state: kubectl get pods

but when I try to hit localhost:1026/verion api from pod's shell it shows error: error

I have tried to see logs of the pod and docker container created at worker node but nothing is showing.

At master node: kubectl logs

At worker node: docker ps docker logs docker logs

Please correct me if I am doing anything wrong and suggest me the way in which I can proceed to deploy orion using helm chart.

Hello,
can you provide more information about your mongo-db deployment, especially its configuration?
Beside that, please also show the service-definition of "mongo".
Best,
Stefan

I have set the log level to debug and I got below logs

Hi @wistefan , I have used kompose to deploy mongodb. Below is the yaml file which I have used:

apiVersion: apps/v1
kind: Deployment
metadata:
  annotations:
    kompose.cmd: kompose convert
    kompose.version: 1.22.0 (955b78124)
  creationTimestamp: null
  labels:
    io.kompose.service: mongo
  name: mongo
spec:
  replicas: 1
  selector:
    matchLabels:
      io.kompose.service: mongo
  strategy: {}
  template:
    metadata:
      annotations:
        kompose.cmd: kompose convert
        kompose.version: 1.22.0 (955b78124)
      creationTimestamp: null
      labels:
        io.kompose.service: mongo
    spec:
      containers:
        - args:
            - --nojournal
          image: mongo:3.6
          name: mongo
          resources: {}
      restartPolicy: Always
status: {}
---
apiVersion: v1
kind: Service
metadata:
  name: mongo

  selector:
    io.kompose.service: mongo
  ports:
    - protocol: TCP
      port: 27017
      targetPort: 27017

Do we need to deploy mongo via chart only or we can do this way?

[Stefan Wiedemann]

You can deploy mongo without a chart, too. Does the mongo db require authentication? Since none is configured on orion, it might be the problem. Beside that, you should check if mongo is reachable from the orion pod. You can execute into it and try to connect it via curl.
