All machines will be provisioned with fixed private IP addresses to simplify the bootstrap process.
To make our Kubernetes control plane remotely accessible, a public IP address will be provisioned and assigned to a Load Balancer that will sit in front of the 3 Kubernetes controllers.
Create all machines in the Informatik vsphere, set them up to use puppet.
All machines of the ICC, except the members of the etcd-cluster must be set up within the FuL network.
Assure proper permissions are set in the ACL:
- access from controllers to etcd-cluster
- access from controllers to puppet master
Create a public IP address that will be used by remote clients to connect to the Kubernetes control plane:
This is set to IP_OF_YOUR_LB and set in DNS as HOSTNAME
Information the HAProxy load balancer that will enable reaching all nodes on the same IP can be found in the chapter on the HAProxy setup
All the VMs in this lab will be provisioned using Ubuntu 16.04 mainly because it runs a newish Linux kernel with good support for Docker.
The controlers should have 4 GByte of RAM.
