Agent Upgrade

The steps to upgrade an agent differ depending on whether the agent was originally installed as a container or as a service.

This section describes how to check the current version of the installed agents, and then how to upgrade them.

Agent Version Check

Kubernetes installation

If the agent is installed in a Kubernetes environment, run:

kubectl get pods -n sysdig-agent -o=jsonpath='{.items[0].spec.containers[:1].image}'

Container/Docker Installation

If the agent is installed as container, run:

docker exec sysdig-agent /opt/draios/bin/dragent --version

Service Installation

If the agent is installed as a service, run:

/opt/draios/bin/dragent --version

The agent version can also be found in the agent log file: /opt/draios/logs/draios.log.

Look for the “Agent starting” message, which is logged whenever the agent restarts.

Update Agent

Update the containerized agent version as you normally update any container; the basic steps are below.

Use the full run command as shown in the Settings > Agent Installation tab of your account.

Containerized Agent

To see which agent versions are available see tags.

Kubernetes

Helm

1. Update the chart:

   helm repo update
   

2. Do one of the following:

• If you have deployed the chart with a values.yaml file, modify or add (if it’s missing) the agent.image.tag field and run:

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

• If you have deployed the chart by setting the values as CLI parameters, run:

  helm upgrade --namespace sysdig-agent --set agent.image.tag=<latest_version> --reuse-values sysdig-agent sysdig/sysdig-deploy
  

  Replace <latest_version> with the latest version number of Sysdig agent.

For more information on using Helm, see Helm Charts.

Manual

Check whether .yaml files must be updated:

Perform update:

kubectl set image ds/sysdig-agent sysdig-agent=sysdig/agent:<tag>

Watch update status:

kubectl rollout status ds/sysdig-agent

Docker

Basic Steps: stop the agent, remove it, pull the new agent, and install it.

The exact Docker command can also be found in the Sysdig Settings > Agent Installation menu.

docker stop sysdig-agent
docker rm sysdig-agent
docker pull sysdig/agent
docker run . . .

Service Agent

For service (non-containerized) agent installations, updates are installed as part of the normal system upgrade available with apt-get or yum.

Debian, Ubuntu

apt-get update
apt-get -y install draios-agent

CentOS, RHEL, Fedora, Amazon AMI, Amazon Linux 2

yum clean expire-cache
yum -y install draios-agent
