Is it Observable

Episode : Kubescape

This repository contains all the files required to run the tutorial environment related to the episode dedicated to Kubescape

this repository will use solutions to measure the usage of those agents, we will rely on:

• the OpenTelemetry Demo

• ungard application

• Goat application to generate security violation

• All the observability data generated by the environment would be sent to Dynatrace.

Prerequisite

The following tools need to be install on your machine :

• jq
• kubectl
• git
• gcloud ( if you are using GKE)
• Helm

1.Create a Google Cloud Platform Project

PROJECT_ID="<your-project-id>"
gcloud services enable container.googleapis.com --project ${PROJECT_ID}
gcloud services enable monitoring.googleapis.com \
cloudtrace.googleapis.com \
clouddebugger.googleapis.com \
cloudprofiler.googleapis.com \
--project ${PROJECT_ID}

2.Create a GKE cluster

ZONE=europe-west3-a
NAME=isitobservable-kubescape
gcloud container clusters create ${NAME} --zone=${ZONE} --machine-type=e2-standard-4 --num-nodes=2

3. Clone Github repo

git clone  https://github.com/isitobservable/kubescape
cd kubescape

Getting started

Dynatrace Tenant

1. Dynatrace Tenant - start a trial

If you don't have any Dynatrace tenant , then I suggest to create a trial using the following link : Dynatrace Trial Once you have your Tenant save the Dynatrace tenant url in the variable DT_TENANT_URL (for example : https://dedededfrf.live.dynatrace.com)

DT_TENANT_URL=<YOUR TENANT Host>

2. Create the Dynatrace API Tokens

The dynatrace operator will require to have several tokens:

• Token to deploy and configure the various components
• Token to ingest metrics and Traces

Operator Token

One for the operator having the following scope:

• Create ActiveGate tokens
• Read entities
• Read Settings
• Write Settings
• Access problem and event feed, metrics and topology
• Read configuration
• Write configuration
• Paas integration - installer downloader

Save the value of the token . We will use it later to store in a k8S secret

API_TOKEN=<YOUR TOKEN VALUE>

Ingest data token

Create a Dynatrace token with the following scope:

• Ingest metrics (metrics.ingest)
• Ingest logs (logs.ingest)
• Ingest events (events.ingest)
• Ingest OpenTelemetry
• Read metrics

Save the value of the token . We will use it later to store in a k8S secret

DATA_INGEST_TOKEN=<YOUR TOKEN VALUE>

1. Deploy the environment without security solutions

The application will deploy the entire environment:

chmod 777 deployment.sh
./deployment.sh  --clustername "${NAME}" --dturl "${DT_TENANT_URL}" --dtingesttoken "${DATA_INGEST_TOKEN}" --dtoperatortoken "${API_TOKEN}" 

Tutorial Steps

Kubearmor Notebook

Kubescape Dashboard

Let's deploy the dashboard located : dynatrace/kubescape dashboard.json

In dynatrace , Open The Dashboard application and click on upload

This dashboard will keep track on the health of tetragon:

• ressource usage
• the various rules

all those dashboard are uisng the logs , spans and metris
