[newrelic-infrastructure] doesn't reload its own ConfigMap

[freehck-codefresh]

Found that this workaround works:

podAnnotations:
   checksum/config: {{ tpl "configmap.yaml" . | sha256sum }}

[freehck-codefresh]

I mean, it works it we put it into the values.yaml.
Feel free to use it as a default or as one of the possible solutions.

It seems to me that idea with annotation with config checksum is a good way to resolve this.

@freehck-codefresh @invidian i am trying to achieve integration host for redis. I commented out intergations_config part for redis is values.yaml
And deployed with helm upgrade --install --reuse-values values.yaml newrelic-bundle newrelic/nri-bundle
But i don't see any configmap created and also no metrics

[gauravgola96]

@invidian @freehck-codefresh I have also tried yaml manifest

apiVersion: v1
kind: ConfigMap
metadata:
  name: nri-integration-cfg
  namespace: newrelic
data:
  redis-config.yml: |
    ---
    # Run auto discovery to find pods with label "app=redis"
    # https://docs.newrelic.com/docs/integrations/host-integrations/installation/container-auto-discovery
    discovery:
      command:
        # Use the following optional arguments:
        # --namespaces: Comma separated list of namespaces to discover pods on
        # --tls: Use secure (TLS) connection
        # --port: Port used to connect to the kubelet. Default is 10255
        exec: /var/db/newrelic-infra/nri-discovery-kubernetes --namespaces redis --tls --port 10250
        match:
          label.app: redis
    integrations:
      - name: nri-redis
        env:
          # using the discovered IP as the hostname address
          HOSTNAME: ${discovery.ip}
          PORT: 6379
          PASSWORD: '***'
          REMOTE_MONITORING: true
          use_unix_socket: true
        labels:
              type: cache
              env: staging

and mounted volume in newrelic-infra daemonset as well

 volumeMounts:
            - name: dev
              mountPath: /dev
            - name: host-docker-socket
              mountPath: /var/run/docker.sock
            - name: log
              mountPath: /var/log
            - name: host-volume
              mountPath: /host
              readOnly: true
            - name: integration-config
              mountPath: /etc/newrelic-infra/redis-config.yml
              subPath: redis-config.yml

      volumes:

        - name: integration-config
          configMap:
            name: nri-integration-cfg

when i checked in pod log
./nri-redist throws[FATAL] can't continue: Redis connection through TCP failed, got error: dial tcp 192.168.1.41:6379: connect: connection refused

but i manually run it with
./nri-redis -hostname redis-master.redis.svc.cluster.local -port 6379 -password '***'
it connects
any help is really appreciated !

Fixed with the release of nri-kubernetes v3: https://github.com/newrelic/nri-kubernetes/blob/aa3e8c09a57317b45d97cce733b29074650fb25d/charts/newrelic-infrastructure/templates/kubelet/daemonset.yaml#L24-L29
