Sysdig

Sysdig is a unified platform for container and microservices monitoring, troubleshooting, security and forensics. Sysdig platform has been built on top of Sysdig tool and Sysdig Inspect open-source technologies.

Introduction

This chart deploys various Sysdig components into your Kubernetes cluster.

Currently included components:

• Sysdig agent
• Sysdig NodeAnalyzer
• Sysdig KSPM Collector

Prerequisites

• Kubernetes 1.9+ with Beta APIs enabled
• Helm v3+

Installation

1. Add the Sysdig Helm repo:

   helm repo add sysdig https://charts.sysdig.com/
   

2. Collect the following values:

   • ACCESS_KEY: This is your Sysdig access key
   • SAAS_REGION: The Sysdig SAAS region the agents will connect to. Use one of the following values:
     • "us1"
     • "us2"
     • "us3"
     • "us4"
     • "eu1"
     • "au1"
     • "custom": For on-prem installations, use custom and override the endpoints for each component. For more information, see Configuration.
   • CLUSTER_NAME: An identifier for your cluster

3. Create a namespace for the Sysdig agent:

   kubectl create ns sysdig-agent
   

4. Do one of the following:

   • Using the release name sysdig, run the following snippet to install the release into the namespace sysdig-agent:

   helm install sysdig sysdig/sysdig-deploy \
       --namespace sysdig-agent \
       --set global.sysdig.accessKey=ACCESS_KEY \
       --set global.sysdig.region=SAAS_REGION \
       --set global.clusterConfig.name=CLUSTER_NAME
   

   GKE Autopilot: GKE Autopilot environments require an additional configuration parameter, agent.gke.autopilot=true, to install the Sysdig agent:

   helm install sysdig sysdig/sysdig-deploy \
        --namespace sysdig-agent \
        --set global.sysdig.accessKey=ACCESS_KEY \
        --set global.sysdig.region=SAAS_REGION \
        --set global.clusterConfig.name=CLUSTER_NAME \
        --set agent.gke.autopilot=true \
        --set agent.slim.enabled=false \
        --set nodeAnalyzer.enabled=false
   

   • Install with a values file.

     To do so, create a new file values.sysdig.yaml:

     global:
       sysdig:
         accessKey: ACCESS_KEY
         region: SAAS_REGION
       clusterConfig:
         name: CLUSTER_NAME
     

     and install it with:

     helm install -n sysdig-agent sysdig sysdig/sysdig-deploy -f values.sysdig.yaml
     

Migrating from sysdig chart

To easily migrate from the previous sysdig chart to the new unified sysdig-deploy chart, use the migration helper script from this repo. This script will help re-map your existing values from the sysdig chart, allowing you to deploy this chart with the exact same configuration.

Note: unlike the previous chart, this chart only supports Helm 3. If you have not already done so, please upgrade your Helm version to 3.x to use this chart.

Requirements:

• Python 3.x
• PyYAML

Save the user-values from the currently deployed version of the sysdig chart:

helm get values -n sysdig-agent sysdig-agent -o yaml > values.old.yaml

Note: the migration script has a dependency on pyyaml, which can be installed with

pip install pyyaml

Run the migration script and redirect the output to a new file. For example, if the old values were saved to values.old.yaml:

python scripts/migrate_values.py values.old.yaml > values.new.yaml

Now the sysdig chart can be removed and replaced with the sysdig-deploy chart.

helm delete -n sysdig-agent sysdig-agent

helm repo update
helm install -n sysdig-agent sysdig sysdig/sysdig-deploy -f values.new.yaml

Differences between sysdig and sysdig-deploy

There are several differences in the agent and node-analyzer components in the new chart compared to the old one. The majority of the differences are in the metadata names and labels.

• helm.sh/chart: sysdig-<version> -> helm.sh.chart: nodeAnalyzer-<version> or helm.sh.chart: agent-<version>
• label app.kubernetes.io/name: agent for the agent daemonset and pods
• label app.kubernetes.io/name: nodeanalyzer for the nodeAnalyzer daemonset and pods
• new configmap and secret for nodeAnalyzer named <release-name>-nodeanalyzer
• label app: sysdig-agent is no longer on nodeAnalyzer components

Upgrading

Refresh the sysdig helm repo to get the latest chart.

helm repo update

Get the currently deployed values and save them to values.sysdig.yaml.

helm get values -n sysdig-agent sysdig -o yaml > values.sysdig.yaml

Upgrade to the latest version of the chart:

helm upgrade -n sysdig-agent sysdig sysdig/sysdig-deploy -f values.sysdig.yaml

Configuration

The following table lists the configurable parameters of this chart and their default values.

Agent

For configuration values of the agent, see the Agent subchart README. Prefix all the specific configurations with agent. to apply them to the chart.

Example: override proxy variable for Agent chart

As a command line parameter:

helm install sysdig sysdig/sysdig-deploy \
    --namespace sysdig-agent \
    --set global.sysdig.accessKey=ACCESS_KEY \
    --set global.sysdig.region=SAAS_REGION \
    --set global.clusterConfig.name=CLUSTER_NAME \
    --set global.proxy.httpProxy=PROXY_URL \
    --set agent.proxy.httpProxy=OVERRIDE_PROXY_URL

As a values file:

global:
  sysdig:
    accessKey: ACCESS_KEY
    region: SAAS_REGION
  clusterConfig:
    name: CLUSTER_NAME
  proxy:
    httpProxy: PROXY_URL
