  • Enabling copy and paste in ESX VM

    I really wanted copy and paste between Windows and VMs running in ESX. This is what finally worked for me. Note this was for ESX “6.0.0 Update 3 (Build 5050593)”. I was using VMware Workstation 16 Player “16.1.2 build-17966106” on Windows 10. Also, this only worked when I ran “Console | Launch remote console”. It… read more…

  • OKD 4.5 small cluster on ESX

    I needed to create a small OKD/OpenShift setup so I could play around with it and get comfortable with using it, developing on it and administering it. Additionally I wanted it to be somewhat similar in setup to what we do at work. This was originally based on the excellent post by Craig Robinson, but… read more…

  • Restored OKD Cluster Not Starting

    I run my OKD cluster on a set of VMs in VMware ESXi. My backups consist of shutting down all VMs and then copying them somewhere else – so full shutdown and backup. The cluster setup was done using the steps outlined in OKD 4.5 small cluster on ESX. This has worked well and I… read more…

  • Enable ssh in and out of ESX

    By default an ESX server doesn’t allow you to ssh to it or ssh from it to another host. Being able to ssh to an ESX host can be very useful to do base unix functions including moving files around and so on. Being able to ssh out and in particular to another ESX host… read more…

  • Add Catalog Sources To OperatorHub

    If you have followed my post OKD 4.5 small cluster on ESX you find that when you look at the OperatorHub in OKD you only see the community operators. The problem appears to be that an out of the box OKD install only has the “Community Operators” enabled. The trick is to enable the rest.… read more…

  • Test DNS connectivity

    I was setting up OKD on a separate VLAN and wanted to used the OKD DNS service but it just wasn’t working and I felt it was a connectivity/firewall issue but could not find a tool to test. I was testing on my Windows 10 desktop connecting to a Fedora DNS server. Port Query I… read more…

  • Failed to list *v1.ConfigMap

    I was setting up an OKD single node cluster and to test if it was up I ran: openshift-install –dir=/opt/okd4/install_dir/ wait-for bootstrap-complete –log-level=debug Then I got the following error messages: https://api.lab.okd.local:6443/api/v1/namespaces/kube-system/configmaps?fieldSelector=metadata.name%3Dbootstrap&limit=500&resourceVersion=0: EOF E0104 15:32:18.605736 1642 reflector.go:153] k8s.io/client-go/tools/watch/informerwatcher.go:146: Failed to list *v1.ConfigMap: Get https://api.lab.okd.local:6443/api/v1/namespaces/kube-system/configmaps?fieldSelector=metadata.name%3Dbootstrap&limit=500&resourceVersion=0: EOF E0104 15:32:19.607338 1642 reflector.go:153] k8s.io/client-go/tools/watch/informerwatcher.go:146: Failed to list *v1.ConfigMap: Get https://api.lab.okd.local:6443/api/v1/namespaces/kube-system/configmaps?fieldSelector=metadata.name%3Dbootstrap&limit=500&resourceVersion=0:… read more…

  • OMV fix accidentally split mirror RAID

    I had setup a mirrored RAID in OMV and then the PC hardware, not the disks I should emphasize, failed and I needed to move the system disk and two data disks to other hardware. Because I decided to test each disk separately this broke the mirror and in OMV I now saw: Work off… read more…
