Logging

Setting up an EFK stack on Kubernetes.

Exercise 1: Installing the Kubernetes elasticsearch logging add-on

  1. Install the Elasticsearch Logging add-on from the kops repo

    kubectl create -f https://raw.githubusercontent.com/kubernetes/kops/master/addons/logging-elasticsearch/v1.6.0.yaml

    Review the yaml file carefully and verify all objects have been created successfully. This will add Fluentd for parsing/shipping, Elasticsearch for storing/indexing and Kibana for visualization.

    Note: There will be an error creating one object. You will need to troubleshoot the failure, update the yaml locally and redeploy.

  2. Start a proxy on port 8080.

    kubectl proxy -p 8080

  3. Forward port 8080 from the Cloud Shell to your local machine.

    From Cloud Shell top menu bar select option Preview on port 8080

  4. View the Kibana service on the /proxy/ endpoint.

    Append api/v1/namespaces/kube-system/services/kibana-logging/proxy to the top level domain.

    E.g. https://8080-dot-3438793-dot-devshell.appspot.com/api/v1/namespaces/kube-system/services/kibana-logging/proxy

  5. Explore the Kibana Dashboard and what information you can find there.

Exercise 2 (Optional): Setup a Kibana Dashboard for Kube-System

  1. Create a dashboard to quickly identify the type of error we saw in the previous exercise.
