Note that is this the single node cluster setup rather than the popular multi-node cluster guide https:\/\/itnext.io\/guide-installing-an-okd-4-5-cluster-508a2631cbee<\/a><\/p>\n\n\n\n This guide is really documentation on what I did to setup my small lab environment. A big part of the point of it is for me to be able to document what I did so if I have to repeat stuff, as often seems to be the case for me, then I can do so. As such this is not a dummies guide. <\/p>\n\n\n\n This document does not describe how to use OKD, nor how to create projects or do builds. It is purely about getting a working environment<\/p>\n\n\n\n I am doing the full install on an HP Compaq Elite 8300 SFF:<\/p>\n\n\n\n I am using a Windows 10 desktop with my Firefox as my primary browser. <\/p>\n\n\n\n Additionally I operate a SonicWall TZ 215 which takes the VLAN and makes it a sub-interface to the LAN. <\/p>\n\n\n\n I am looking to have a separate ESX box to run an extra worker node, partly to add extra capacity but also partly to understand how it will work with mulitple worker nodes.<\/p>\n\n\n\n Craig’s guide is for installing on Hyper-V on Windows but I needed to install on ESX because it brought multiple advantages. <\/p>\n\n\n\n I have setup my local environment using it’s own VLAN, 20, which I have called “OKD VLAN20”. This is configured on the ESX hosts and also on my Sonicwall firewall. This VLAN uses the range 192.168.205.x and is a “VLAN Sub-Interface” to my home lan of 192.168.202.x.<\/p>\n\n\n\n All my hosts are on the VLAN “OKD VLAN20” <\/p>\n\n\n\n You will have noticed that the vCPU and RAM far exceed that on my ESX server. ESX allows you to over subscribe memory and vcpu and by configuring the specified memory and vcpu it means OKD sees the specified resources. Also the resources are not consumed at once so the reality is it works!<\/p>\n\n\n\n The services host, “okd4-services”, has a large disk, currently 200GB, this is primarily because we put our persistent volumes on this host. It just makes things a lot easier in a dev environment, it means for example we can just backup the VMs and you have everything<\/strong>!<\/p>\n\n\n\n This guide is really documentation on what I did to setup this small lab environment. A big part of the point of it is for me to be able to document what I did so if I have to repeat stuff, as often seems to be the case for me, then I can do so.<\/p>\n\n\n\n As such this is not a dummies guide. I assume you know your way around ESX and it’s web console and equally know your way around unix.<\/p>\n\n\n\n Craig has kindly provided customized config file for a number of things and these can be found at https:\/\/github.com\/cragr\/okd4-snc-hyperv<\/a> I have taken these as my starting place and tweaked for my environment:<\/p>\n\n\n\nOverview<\/h1>\n\n\n\n
