I want to deploy the hadoop platform into the cluster.
$ sudo docker stack deploy -c docker-compose-v3.yml hadoop
network "hbase" is declared as external, but could not be found. You need to create a swarm-scoped network before the stack is deployed
How can I resolve this error?
you need to create your Network first:
docker network create --driver overlay hbase
in your compose
you specify the network hbase
as external
but it seems there is no such network exists
