Configuration

A reference list of, mostly internal, configuration options.

Helm Charts

The Helm charts accept, at least, the options as shown with their default in values.yaml:

Environment Variables

The controllers can be started with these environment variables:

  • CATTLE_DEV_MODE - used to debug wrangler, not usable
  • FLEET_CLUSTER_ENQUEUE_DELAY - tune how often non-ready clusters are checked
  • FLEET_CPU_PPROF_PERIOD - used to turn on performance profiling

Configuration

In cluster configuration for the agent and fleet manager. Changing these can lead to full re-deployments.

The config struct is used in both config maps:

  • cattle-fleet-system/fleet-agent
  • cattle-fleet-system/fleet-controller

Labels

Labels used by fleet:

  • fleet.cattle.io/agent=true - NodeSelector label for agent's deployment affinity setting
  • fleet.cattle.io/non-managed-agent - managed agent bundle won't target Clusters with this label
  • fleet.cattle.io/repo-name - used on Bundle to reference the git repo resource
  • fleet.cattle.io/bundle-namespace - used on BundleDeployment to reference the Bundle resource
  • fleet.cattle.io/bundle-name - used on BundleDeployment to reference the Bundle resource
  • fleet.cattle.io/managed=true - cluster namespaces with this label will be cleaned up. Other resources will be cleaned up if it is in a label. Used in Rancher to identify fleet namespaces.
  • fleet.cattle.io/bootstrap-token - unused

Annotations

Annotations used by fleet:

  • fleet.cattle.io/agent-namespace
  • fleet.cattle.io/bundle-id
  • fleet.cattle.io/cluster, fleet.cattle.io/cluster-namespace - used on a cluster namespace to reference the cluster registration namespace and cluster name
  • fleet.cattle.io/cluster-group
  • fleet.cattle.io/cluster-registration-namespace
  • fleet.cattle.io/cluster-registration
