I am playing with fleet's test mode

fleet test

and I want to pass labels to it, but something doesn't work. I have created a

fleet.yaml

and running this command:

docker run \
   -it \
   -v `pwd`:/manifests \
   --rm \
   --name fleet \
   --entrypoint sh rancher/fleet-agent:v0.3.9 \
   -c "cd /manifests && fleet \
   --debug test \
   -t devmode \
   -l env=dev"

but it's like

env=dev

is not being set. Also, is it possible to set it so that

global.fleet.clusterLabels.env

will turn to

dev

?
