Version 1.2.6 does not provide metrics and version 1.4.1 or 1.4.3 do not exist as container image

[telmich]

Hello,

I am trying to use bird_exporter with bird 2.15.1. I created a k8s manifest as follows:

      containers:
        - name: bird
          image: "ungleich/bird:{{ .Chart.AppVersion }}"
          command:
            - /bin/sh
            - -c
            - "sh /scripts/rp_filter_forward.sh && /usr/sbin/bird -f -c /bird/bird.conf"
          securityContext:
            privileged: true
            capabilities:
              add:
                - NET_BIND_SERVICE
                - NET_RAW
                - NET_ADMIN
          volumeMounts:
            - name: birdconfig
              mountPath: "/bird"
            - name: varrun
              mountPath: "/var/run"
        - name: bird-exporter
          image: czerwonk/bird_exporter:v1.2.6
          args: ["-format.new=true", "-bird.socket=/var/run/bird.ctl"]
          resources:
            limits:
              cpu: 100m
              memory: 32Mi
            requests:
              cpu: 100m
              memory: 32Mi
          volumeMounts:
            - name: varrun
              mountPath: "/var/run"
              readOnly: true

The curl on :9324/metrics results into an empty reply:

% curl -v http://sfpapu1:9324/metrics

Trying to use newer versions such as 1.4.1 (mentioned in sample chart) or 1.4.3 (tag exists) does not seem to have a corresponding image on https://hub.docker.com/r/czerwonk/bird_exporter/tags.

Are there any plans for pushing out newer images and am I doing something totally wrong with 1.2.6 that it does not respond to metrics?

I just build and pushed ungleich/bird_exporter:1.4.3-9-gea10eb5 (build process works flawlessly!) and now I get:

bird_socket_query_success 0

which is a bit better than before.

Just checked, the unix socket communication works:

socat - UNIX-CONNECT:/var/run/bird.ctl
0001 BIRD 2.15.1 ready.

Checking the args, I think I see the bug..."-bird.v2" might be the missing part... and it indeed is:

bird_socket_query_success 1
