Problem

Vector seems to fail to annotate logs from the kubernetes_logs source when pod names are reused. I didn't reproduce this, but there are a few comments (in the references section) that seem to indicate this is the case.

One hypothesis is that https://github.com/vectordotdev/vector/blob/aee1984c15ff8e43992ce80fc4f3f1b95220f4fc/src/sources/kubernetes_logs/pod_metadata_annotator.rs#L100 should be looking up by the uid as well (under extra) rather than just name and namespace.

Hello. Any updates here? We are suffering :(

Hi @r0b3r4 ! Unfortunately not yet, but it is on our backlog. We are also happy to help guide a contribution if someone has the time and ability to address it.

Hello,

Error

Failed to annotate event with pod metadata

is happened here

https://github.com/vectordotdev/vector/blob/c402e6ed94400959dbc298d4b342dcb0842089d4/src/sources/kubernetes_logs/mod.rs#L498

and None is maybe happened here https://github.com/vectordotdev/vector/blob/c402e6ed94400959dbc298d4b342dcb0842089d4/src/sources/kubernetes_logs/pod_metadata_annotator.rs#L99 or here https://github.com/vectordotdev/vector/blob/c402e6ed94400959dbc298d4b342dcb0842089d4/src/sources/kubernetes_logs/pod_metadata_annotator.rs#L101

Second variant is more suitable

And i think it's happened because stored information about pod is deleted with event Deleted https://github.com/vectordotdev/vector/blob/c402e6ed94400959dbc298d4b342dcb0842089d4/src/kubernetes/reflector.rs#L38

After pod is deleted (some one wrote that problem is appear when the pod scale down and up and it's name is the same) event Delete is delayed.
The new event Create, store information about new created pod into Store, but when delay timer exceeded - the information about old pod with the same name is deleted, and because new pod has the same name from Store deleted information about new create pod And code self.pods_state_reader.get(&obj)?; return None

It's just my opinion based on my investigation of the problem. I cannot reproduce the problem by myself, and my opinion it's just a theory

comment: @jszwedko

One hypothesis is that ... should be looking up by the uid as well (under extra) rather than just name and namespace

I think it won't work

1. We can't take uid, that presented in Kubernetes Resource

he looks like this uid: 5751f785-5689-4868-a573-d9e0096821ff but the pod_uid that we can get from file_info is not that uid that we need

2. extra not implement Hash and PartialEq

https://github.com/kube-rs/kube-rs/blob/bf885f05c39c046f68e34f19b95402d3326c1715/kube-runtime/src/reflector/object_ref.rs#L56

and when we try

https://github.com/vectordotdev/vector/blob/c402e6ed94400959dbc298d4b342dcb0842089d4/src/sources/kubernetes_logs/pod_metadata_annotator.rs#L101

the method at work will not be based on the data of this field

[jszwedko]

Thanks @sillent . It does appear to be the case that the extra data isn't included in comparisons of pod info. That strikes me as a bit odd. I wonder if we should open an issue upstream on kube-rs to get their thoughts around this.

[shenxn]

Maybe we should consider having our own metadata cache based on uid instead of changing the event order of kube-rs store. It seems that the whole kube-rs is built around resource names instead of uids so it can be hard to just add uid support.

I have steps to reproduce the problem. Hope it helps.

Arch: x86_64 OS: Ubuntu 20.04

1. Install minikube & helm

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube start

curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

2. Install vector using helm

helm repo add vector https://helm.vector.dev
helm repo update

cat <<EOF > values.yaml
role: Agent
service:
  enabled: false
image:
  pullPolicy: IfNotPresent
  repository: timberio/vector

    kubernetes_logs:
      type: kubernetes_logs
      extra_field_selector: "metadata.namespace=app"
      delay_deletion_ms: 30000
      glob_minimum_cooldown_ms: 5000
  sinks:
    stdout:
      type: blackhole
      inputs: [kubernetes_logs]
      print_interval_secs: 1
EOF

helm install vector vector/vector --namespace vector --create-namespace --values values.yaml

3. Deploy a StatefulSet that generates logs

cat <<EOF > stateful.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: flog
  namespace: app
spec:
  selector:
    matchLabels:
      app: flog
  serviceName: flog
  template:
    metadata:
      labels:
        app: flog
    spec:
      containers:
      - name: flog
        image: mingrammer/flog
        imagePullPolicy: IfNotPresent
        command: ['/bin/flog', '--delay', '300ms', '--loop']
EOF

kubectl create namespace app
kubectl apply -f stateful.yaml

4. Wait a few seconds and restart StatefulSet

kubectl rollout restart statefulset flog -n app

5. After delay_deletion_ms (30s), got errors and no longer watching the file

kubectl logs -n vector daemonset/vector -f

Any news :)?

[CharlieC3]

See my comment here, but in summary version 0.25.0 seems to contain a temporary or partial fix to this issue. I wasn't able to locate anything mentioning this in the release notes for this version, so some people may have missed it.

After upgrading to this version a couple weeks ago, I haven't had any annotation issues.

[r0b3r4]

The only thing that confuses me that fix somehow connected with non-related options. As i understand this might works only like temporary kludge, right?

version >=0.25.x +

max_line_bytes: 16777216
max_read_bytes: 16777216
glob_minimum_cooldown_ms: 1000

[CharlieC3]

@r0b3r4 The config options were only helpful in the linked issue for me, while upgrading to version >=0.25.x is specifically what helped me resolve this annotation issue.
