Problem

Currently for init containers we are seeing the container_image and container_image_id labels missing. One such example is from the canal pod. The same is also seen in the init-container of application pod as well. We see the image-name of the container of the canal pod in its config.

{"file":"/var/log/pods/kube-system_canal-<pod_name>_*****************/mount-bpffs/0.log","kubernetes":{"container_name":"mount-bpffs","namespace_labels":{"field.cattle.io/projectId":"#####","kubernetes.io/metadata.name":"kube-system"},"node_labels":{"beta.kubernetes.io/arch":"####","beta.kubernetes.io/instance-type":"####","beta.kubernetes.io/os":"###","failure-domain.beta.kubernetes.io/region":"####","failure-domain.beta.kubernetes.io/zone":"###","kubernetes.io/arch":"###","kubernetes.io/hostname":"node-name","kubernetes.io/os":"###","pod_ip":"###","pod_ips":["###"],"pod_labels":{"controller-revision-hash":"####","k8s-app":"canal","pod-template-generation":"1"},"pod_name":"canal-###","pod_namespace":"kube-system","pod_node_name":"node-name","pod_owner":"DaemonSet/canal","pod_uid":"####"},"message":"<data>.","source_type":"kubernetes_logs","stream":"stdout","timestamp_end":"time data"}

I unfortunately haven't been able to reproduce this issue yet, but thank you for opening it!

I am seeing the same for some of the init containers

[hd-deman]

Same issue here. Init containers don’t have .kubernetes.container_id and .kubernetes.container_image Vector: 0.46.1-distroless-libc, Kubernetes(EKS): v1.30.11

[ayaroshenko-sds]

The same issue: Init containers also do not have .kubernetes.container_id and .kubernetes.container_image.

Details:

• Vector: 0.47.0-distroless-libc
• Kubernetes (AKS): v1.32.3

I'm in testing right now, so If I can help to reproduce or provide some additional information to fix this issue, just let me know
