Configure Tetragon

Depending on your deployment mode, Tetragon configuration can be changed by:


kubectl edit cm -n kube-system tetragon-config
# Change your configuration setting, save and exit
# Restart Tetragon daemonset
kubectl rollout restart -n kube-system ds/tetragon


# Change configuration inside /etc/tetragon/ then restart container.
# Example:
#   1. As a privileged user, write to the file /etc/tetragon/tetragon.conf.d/export-file
#      the path where to export events, example "/var/log/tetragon/tetragon.log"
#   2. Bind mount host /etc/tetragon into container /etc/tetragon
# Tetragon events will be exported to /var/log/tetragon/tetragon.log
echo "/var/log/tetragon/tetragon.log" > /etc/tetragon/tetragon.conf.d/export-file
docker run --name tetragon --rm -d \
  --pid=host --cgroupns=host --privileged \
  -v /etc/tetragon:/etc/tetragon \
  -v /sys/kernel:/sys/kernel \
  -v /var/log/tetragon:/var/log/tetragon \
  quay.io/cilium/tetragon:v1.2.0 \
  /usr/bin/tetragon


# Change configuration inside /etc/tetragon/ then restart systemd service.
# Example:
#   1. As a privileged user, write to the file /etc/tetragon/tetragon.conf.d/export-file
#      the path where to export events, example "/var/log/tetragon/tetragon.log"
#   2. Bind mount host /etc/tetragon into container /etc/tetragon
# Tetragon events will be exported to /var/log/tetragon/tetragon.log
echo "/var/log/tetragon/tetragon.log" > /etc/tetragon/tetragon.conf.d/export-file
systemctl restart tetragon

For Container or systemd deployments, see the Daemon configuration reference.

Enable Process Credentials

On Linux each process has various associated user, group IDs and capabilities known as process credentials. To enable visility into process_credentials, run Tetragon with enable-process-creds setting set.


kubectl edit cm -n kube-system tetragon-config
# Change "enable-process-cred" from "false" to "true", then save and exit
# Restart Tetragon daemonset
kubectl rollout restart -n kube-system ds/tetragon


echo "true" > /etc/tetragon/tetragon.conf.d/enable-process-cred
docker run --name tetragon --rm -d \
  --pid=host --cgroupns=host --privileged \
  -v /etc/tetragon:/etc/tetragon \
  -v /sys/kernel:/sys/kernel \
  -v /var/log/tetragon:/var/log/tetragon \
  quay.io/cilium/tetragon:v1.2.0 \
  /usr/bin/tetragon


# Write to the drop-in file /etc/tetragon/tetragon.conf.d/enable-process-cred  true
# Run the following as a privileged user then restart tetragon service
echo "true" > /etc/tetragon/tetragon.conf.d/enable-process-cred
systemctl restart tetragon
