I new to kubernetes and kobs and are starting to create a cluster using

kops create cluster --zones eu-central-1a,eu-central-1b  ${NAME}

After I have created I can see that the following

> kops get instancegroups --name=${NAME}
NAME                    ROLE    MACHINETYPE     MIN     MAX     ZONES
master-eu-central-1a    Master  t3.medium       1       1       eu-central-1a
nodes-eu-central-1a     Node    t3.medium       1       1       eu-central-1a
nodes-eu-central-1b     Node    t3.medium       1       1       eu-central-1b

Where I would expect the output to look more like this following the tutorial.

NAME                    ROLE    MACHINETYPE     MIN     MAX     ZONES
master-eu-central-1a    Master                  1       1       eu-central-1a
nodes                   Node    t2.medium       2       2

I can of course configure both the nodes in each subnet but it seems wrong. Am I on the wrong track?

That is the expected node count. The cluster was created with --zones eu-central-1a,eu-central-1b. According to the documentation kops will create one node per zone:

--node-count int32 Set total number of nodes. Defaults to one node per zone

If kops should create only one node --zones eu-central-1a should be set or set --node-count 1. I guess this setting can be changed with kops edit command.
