Upgrades

Zen Mesh uses Helm for upgrades. Always check the changelog before upgrading.

Standard Upgrade

helm repo update
helm upgrade zen-agent zenmesh/zen-agent \
  --namespace zen-mesh \
  --reuse-values

Helm performs a rolling upgrade by default. The agent and egress pods are replaced one at a time, ensuring continuous delivery.

Review the changelog for breaking changes
Back up your configuration: helm get values zen-agent -n zen-mesh > values-backup.yaml
Verify cluster health: all pods in zen-mesh namespace are Running

If an upgrade causes issues:

helm rollback zen-agent <revision> --namespace zen-mesh

To find the previous revision:

helm history zen-agent --namespace zen-mesh
