Advanced HA deployment

To create an HA deployment with 3 masters in 3 AZs, please refer to the Kops documentation and try something like this:

kops create cluster \
--name kubernauts2.k8s.local \
--state ${KOPS_STATE_STORE}    \
--node-count 3     \
--zones eu-central-1a,eu-central-1b,eu-central-1c     \
--master-zones eu-central-1a,eu-central-1b,eu-central-1c     \
--node-size t2.micro     \
--master-size t2.micro     \
--topology public     \
--networking calico  \
--target=terraform

With that the terraform model with be created under out/terraform.

Please verify your terraform version and run the following commands:

$ terraform version
Terraform v0.10.0

$ cd out/terraform/
$ terraform init
$ terraform plan
$ terraform apply

You should get the terraform output like this:

In AWS Web-Console you should see 3 masters and 3 nodes running in 3 different AZs:

SSH into the master and enjoy your HA'ed Kubernetes 1.7 cluster:
