Overview

Logs every state of a given watched resource in mongodb. This allows us to construct timelines of what happened during incidents. This component can provide data to external observability tools. Some more examples:

• A given workload started logging lots of errors 20mins after the last deployment. Go through all the states of related objects that changed in that time period to see what could have led to the incident
• Correlate state changes of k8s objects with external events (metrics from newrelic, stackdriver, etc)

Quickstart

Install mongodb in your cluster

More information here: https://github.com/bitnami/charts/tree/master/bitnami/mongodb

1. helm repo add bitnami https://charts.bitnami.com/bitnami'
2. helm repo update
3. helm install mongodb bitnami/mongodb
4. kubectl create namespace k8s-event-exporter

Create secrets containing mongodb credentials

kubectl create secret generic mongodb-credentials --from-literal=MONGO_PASSWORD=$(kubectl get secret --namespace default mongodb -o jsonpath="{.data.mongodb-root-password}" | base64 --decode) --namespace=k8s-event-exporter

Install the kube-events-exporter

kubectl apply -f https://raw.githubusercontent.com/pydo/kube-events-exporter/master/k8s_event_logger/manifests/manifest.yaml
