It is impossible to execute tasks only on the master node

[Vladimir Maliaev]

"Fuel2 graph execute” can not run individually on master. If I need to run a graph only on master node it is expected to point "master" as a target node in -n NODES parameter.

fuel2 graph execute [-h] -e ENV [-t TYPE] [-n NODES [NODES ...]] [-d]

if I try to use 'master':
fuel2 graph execute: error: argument -n/--nodes: invalid int value: 'master'

if I try to substitute 0:
404 Client Error: Not Found for url: http://172.16.25.2:8000/api/v1/clusters/1/deploy/?nodes=0&graph_type=change_link (NodeCollection not found)

Expected behaviour:
Execute graph only on the Fuel (master)

There is easy workaround - as graph runs for cluster, just apply it on any node, master tasks will be executed also. Lowered priority.

The easy workaround above is good for small deployments or test Labs, not for big clouds in pre-production status. In that case a customer does not give a permission to redeploy any node in the cluster.
