docker-compose command cannot scale the datanode

[taoluo]

Hi,
I want to scale the hadoop datanode to 3, I run the command docker-compose up --scale datanode=3. But the resulting cluster still has only one datanode.
Could you please give me some suggestions on how to run the cluster with multiple datanodes?

Thanks,

You need to configure it in a different way. Please see PR #59.
