OpenShift MachineSets - Build and Scale Your Nodes!

[@6qoo]

Thanks for your great video! I follow your steps to create the machineset (I use OCP 4.12 with vsphere upi with static ip), but the new machine (by increasing the machine count in the machineset) stuck in provisioning state (doesn't finish for one day). May you advise what log or event I should check to fix this problem?

[@OCPdude]

Anything captured under 'Events' when you select your MachineSet in OCP?

[@6qoo]

@@OCPdude I didn't find any events when I select my MachineSet in OCP?

Very nice video ! I am really getting a good info .. i am doing alot of POC on top of OCP .

[@OCPdude]

I am glad you found it useful. For more information, don’t forget to visit my GitHub, and thank you for the follows!

@@OCPdude Your welcome ! Sure i will do also i have some terraform as well as openshift specific installations automation for cloud native apps on too .

Nicely explained thanks for your video, Can you tell me how you configured your home lab is it from Laptop, using VMware workstation or Virtual box or any Baremetal H/W, pls let me know,

[@OCPdude]

Hi, I am glad you appreciated the video. My lab consists of 4x DL360 HPE servers, they have NVMe, SSD and NL disks and 10Gb networking. I run VMware 6.7U3 on it, and I've tried to keep the 3 nodes I use for the lab identical. The 4th server is used for all the servers & services I use to support the lab environment. This lab is my primary play ground, but you will see me spin up something on a cloud provider from time to time. Thank you for checking out the video!

​@@OCPdude Thanks for the reply to your Lab setup, appreciate your time and effects doing these OCP videos

[@dharanibalaraman4089]

is it possible to set up a similar kind of Lab setup for Openshift for the play groud to test the openshift installation using VMware workstation and creating VM ESXi host installing VMware 6.7U3 , top of it, I have enough RAM and 1TB NVMe SSD storage capacity in my Laptop, pls let me know

[@OCPdude]

@@dharanibalaraman4089 It may be possible to install OCP using vm's created from workstation. I haven't done it, but I believe it could be done. That said, I'd first recommend if one of these other options would be more beneficial : www.openshift.com/try

Does autoscaler work for machine-sets in vmware/UPI installed cluster? Or is it only for clusters in cloud (AWS)?

[@OCPdude]

You can setup machine autoscaling in vmware w/ UPI - it's just a bit more on you to do the setup. I'll add this to my list of things to review/demo.

[@chungnguyenhoang7306]

@@OCPdude have you created anything (review/demo) for the above (machine autoscaling for vmware/UPI) ?

[@davorinkocbek4779]

Nice. Machine for infra node is successfully created, it is provisioned in vmware. But I have some problem with ignition file. Machine is provisioned, but there is an error: ignition [693]: GET error: Get "api-int..:22623/config/worker read: connection refused I created my cluster as you did in your video (vmware on UPI). Do you have any idea what is wrong? Thank you.

[@OCPdude]

Make sure you can get to the endpoint "curl api-int.:22623/config/worker"

[@davorinkocbek4779]

@@OCPdude I can get the endpoint. Curl works fine.

Great Video ! I have a problem, my 3 machines have failed status after installation. I am trying to delete one of them but I have "delete" status all the time. Could you help? Does the status of the machine affect openshift

[@OCPdude]

What is the node's role that is "deleting"? If it is a 'worker' it will likely not have any affect on your cluster unless services are hung and it cannot evaluate them, this sometimes happens with daemonsets. If it's a 'manager/master' node, then the quorum will be affected and depending on it's status it could have an impact on etcd's polling. If it's an infra-node, then it could have an impact - again, based on where it is in the 'deleting' phase.

[@mozi4005]

Can we manage it with static IP ?

[@OCPdude]

That would not be very dynamic would it? Is there a specific use case you are trying to solve?

[@sudheerg9994]

nice video

[@naveenKumar-zy6yh]

Mate instead both screen in one window, why can't you try alt tab to shifting screen. So that we can view clearly

[@OCPdude]

Ha Ha! Looks clear to me - did you check to make sure you playback quality is set to HD 1080? I don't like screen tabbing, I personally find it distracting. I do put a lot of content in print on GitHub - links in the description if it's helpful.
