Some Fleet Metrics

would prefer curl, but okay
more recent fleet versions use deploy/fleet-agent instead of a statefulset

k exec -it -n cattle-fleet-local-system fleet-agent-0 -- wget -qO - monitoring-fleet-controller.cattle-fleet-system.svc.cluster.local:8080/metrics

k exec -it -n cattle-fleet-local-system fleet-agent-0 -- wget -qO - monitoring-gitjob.cattle-fleet-system.svc.cluster.local:8081/metrics

Lint Fleet.yaml Bundle Definitions

nctl command is a local alias for nervctl with options/flags

nctl run -v $(pwd):/tmp/pwd --rm rancher/fleet:v0.14.3-rc.2 -- /usr/bin/fleet apply BUNDLE100 /tmp/pwd/ -o -

### or ...

podman run -v $(pwd):/tmp/pwd --rm docker.io/rancher/fleet:v0.14.3-rc2 /usr/bin/fleet apply BUNDLE100 /tmp/pwd/ -o -
