The goal of today's exercise is to deploy the EFK stack to our Kubernetes cluster and use it to create a dashboard for the Rando app.
Rando is an app that creates logs containing random colors and numbers, it is available here: https://gitlab.com/aransh/rando
Along with it you can find a Helm chart and an optional random.yaml values file used to configure Rando to create a random amount of logs at a random interval.
-
Install the EFK stack onto your cluster (use official Helm charts!). Note:
- It's OK to deploy ElasticSearch with only a single master node for the purposes of this task.
- A values file configured to allow Fluentd to correctly parse JSON logs is attached to the task. You may need to use it.
-
Install the Rando app onto your cluster using Helm.
-
Learn how to query Kibana - write a KQL query to get all Rando's logs (try to be specific!). Save the query.
-
Create a dashboard with Rando app logs' visualizations - Explore the different visualization types to try and make sense of your data (most common number, total randos count, pie-chart of colors, randos/time graph, etc... be creative!).
