# Kubemark Pre-existing Provider Guide
|
||
|
|
|
||
|
|
**Kubemark Master**
|
||
|
|
- A set of Kubernetes control plane components running in a VM
|
||
|
|
|
||
|
|
**Kubernetes Cluster**
|
||
|
|
- A real Kubernetes Cluster that has master and nodes. The hollow-node pods
|
||
|
|
are run in this cluster, but appear as nodes to the Kubemark Master
|
||
|
|
|
||
|
|
## Introduction
|
||
|
|
|
||
|
|
Every running Kubemark setup looks like the following:
|
||
|
|
1) A running Kubernetes cluster pointed to by the local kubeconfig
|
||
|
|
2) A separate VM where the kubemark master is running
|
||
|
|
3) Some hollow-nodes that run on the Kubernetes Cluster from #1
|
||
|
|
4) The hollow-nodes are configured to talk with the kubemark master at #2
|
||
|
|
|
||
|
|
When using the pre-existing provider, the developer is responsible for creating
|
||
|
|
#1 and #2. Therefore, the kubemark scripts will not create any infrastructure
|
||
|
|
or start a kubemark master like in other providers. Instead, the existing
|
||
|
|
resources provided by the VM at $MASTER_IP will serve as the kubemark master.
|
||
|
|
|
||
|
|
## Use Case
|
||
|
|
|
||
|
|
The goal of the pre-existing provider is to use the kubemark tools with an
|
||
|
|
existing kubermark master. It's meant to provide the developer with
|
||
|
|
additional flexibility to customize the cluster infrastructure and still use
|
||
|
|
the kubemark setup tools. The pre-existing provider is an **advanced** use
|
||
|
|
case that requires the developer to have knowledge of setting up a kubemark
|
||
|
|
master.
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
To use the pre-existing provider, the expectation is that there's a kubemark
|
||
|
|
master that is rechable at $MASTER_IP. The machine that the kubemark master is
|
||
|
|
on has to be ssh able from the host that's executing the kubemark scripts. And
|
||
|
|
the user on that machine has to be 'kubernetes'.
|
||
|
|
|
||
|
|
Requirement checklist:
|
||
|
|
- Set MASTER_IP to ip address to the kubemark master
|
||
|
|
- The host where you execute the kubemark scripts must be able to ssh to
|
||
|
|
kubernetes@$MASTER_IP
|
||
|
|
|
||
|
|
## Example Configuration
