How to install OpenShift 4 on Bare Metal - User Provisioned Infrastructure (UPI)

[@enricowelder4256]

Excellent video! So clear and well laid out. I like also how you give an overview of the whole process in the beginning, since this is almost impossible to get from the RedHat documentation when you start with it for the first time.

[@EricLowryUT]

Just followed these instructions for a 4.6 install and it worked like a charm... only thing I did different is that I simply allowed the coreos image to boot completely and then I cut and pasted the following: sudo coreos-installer install /dev/sda \ --insecure \ --image-url 192.168.22.1:8080/ocp4/rhcos \ --insecure-ignition \ --ignition-url 192.168.22.1:8080/ocp4/bootstrap.ign (replacing bootstrap.ign with master.ign and worker.ign respectively) I like this approach because it was much easier to cut and paste into the running vm than it is to type out the kernel options when booting each VM.

[@Oswee]

Had done this with 4.2. But i used Ansible. Doing this by hand is pretty time consuming. Ocp-svc server usually is called Bastion server. :) Will do this in couple of days again but this time for provisioning will use Terraform and Vault for secrets. Hope there are not a lot of changes since 4.2. Great video! Also... if interested in S3 compatible alternative, there are great project called MinIO.

[@arnoldkouevi3445]

Hi ! Please, do you have a gitrepo or something like that where we could see a template of the provisioning with Terraform or Ansible ? Thanks

[@canislupax]

Thank you so much Ryan for doing this! Great How-To. Calm and very clear and structured explanations! Perfekt!

[@EricLowryUT]

Hey Ryan, the HAProxy stats page is totally cool - but I just learned a valuable lesson. I have followed these instructions a couple of times now, with great success. Today, I started working with a slightly larger cluster - one with 3 workers instead of 2. When I looked at the haproxy stats page - one of my worker nodes was red. I freaked out and spent a bunch of time trying to figure it out. Turns out, Openshift "ingress" spins up 2 pods listening on http (80) and https (443) - so you are only going to get "green" on two of your worker nodes at any time. TLDR; if you have more than 2 worker nodes, it's ok if HAProxy thinks some of them are down. Trust `oc get nodes` to tell you if the nodes are up and running!

[@RyanHay]

Hi Eric, good point, I should have mentioned what the HAProxy check was doing. I recall someone else in the comments ran into a similar issue when they made the master nodes schedulable. The console pods were spun up on the master nodes instead of the workers and the HAProxy config wasn't pointing to the masters for http/https. I guess I could have left the HAProxy stats page out but I just found it convenient to visualise installation progress on a long running install.

[@StephenDavies-e1f]

Hi Ryan, an awesome video. One addition, you need to add a firewall rule to ocp-svc - firewall-cmd --zone=internal --add-port=53/tcp --permanent. I found that random Pods would fail DNS lookup. Further investigation showed that happened when the DNS response exceeded 512 bytes on UDP.

[@namitaigit]

This is amazing and supremely helpful! Especially the architecture definition and deployment flow in the beginning. Thank you so much.

[@gypsykid894]

Thanks man your video helped alot understanding pre install setup. warning: utilize your .ign files with in 24 hours of creation else it will give certificate error.

[@Hibernate92]

While the documentation of openshift is a complete mess, you explain the things like a walk in the park. Bravo!

[@paulxb360]

It is impossible to get it done by reading the official documentation, by watching this video, I believe that I can do it ! Thank you ! On question, It is the same way to installing the OKD?

[@RyanHay]

Thanks Paul, yes the same method can be used.

[@mohzaher2000]

Neat, Clear and Complete. Thanks, mate. I could never tell how much time you saved me

[@islameldemery]

Thank you! I followed your steps and got my cluster up and running. Sweet! Worth to mention for windows users (I'm coming from .NET world), I used mobaxterm to edit all configuration files graphically as I'm not as good as Ryan with vim. When configuring certain files Ryan used vim shortcuts to search, find/replace text which I'd have missed easily. I also first deployed all VMs inside a virtual machine of esxi just to test. Although it succeeded, the ocp web console wasn't stable and signs out randomly few minutes after login (the session should last for 24 hours). But when deployed to an esxi on bare metal (exactly like the video) it's perfect and totally stable. I actually used my workstation for that, made myself a vm for development, and passed the GPU/USBs to it using esxi passthrough. Make sure you watch Ryan's other videos to setup nfs storage and load balancer.

Hi Ray, this is an excellent video. We were using this guide video for a long time since 4.6.8 version. But with current 4.7.0 version, though all the machines turn into green but, the installation never completes. "authentication, machine-api, openshift-apiserver" cluster operators never gets up. Also we have installed, assisted version of this 4.7.0. It also stucks at that point. Do you have any experience with 4.7.0?

[@mikehamilton3890]

Loved the video, appreciate the effort. But just a warning to viewers. Don't spent all your time trying to set this up as a test environment and if you need to actually test something anytime soon. I tried this twice from front to back using the latest versions of RedHat with CentOS 8.3, triple checked every step, and I used all the time I had from Friday night to 2AM Monday. Its really close but non functional. Same errors on the GET calls to the api host. So I burned 3 days I didn't have to lose. Don't make my mistake! It looks so close to working but not quite there.

[@tsivanathan]

agreed! already spent 3+ days and still errors on GET calls will try a little bit more before I wrap up for a while I guess...

Kind regards from Lima, Peru.

[@RyanHay]

Thank you! Im not familiar with CentOS Core OS and can't find anything on it. The OpenShift documentation does however specify that the bootstrap and control plane machines must use Red Hat Enterprise Linux CoreOS (RHCOS) as the OS, the compute can use either RHCOS or RHEL.

[@newyoutube3114]

1) What is the process for booting the master/workstations from the ignition files? Bootstrap,master,worker all should be powered on at the same time. Bootstrap first then the master machine about an hour later, then the workers after another hour What does the wait for bootstrap to complete mean 1) The bootstrap server has all the files from the bastion server independent of the status of the master/nodes 2) Or masters and workers are all configured and working What indication can we look at to see what is happening on the bootstrap server. The are logs but what should we look for in the logs. Thanks

[@franciscojimenezcorzo8796]

Excellent video Ryan!, It helped me a lot to understand the whole installation process. I would like to know how to add advanced network configuration, for example to add bonding, I found related information on the RedHat documentation: bond=bond0:em1,em2:mode=active-backup ip=bond0:dhcp Where em1 and em2 are the physical network devices. Those two lines should be added during PXE booting on the RHCOS machines? I found also that we could modify a live install ISO image, with customized network settings profile (using coreos-installer binary). Could you please help me to clarify?

[@normanwolfgang8402]

Hi Ryan thanks for the comprehensive tutorial. I have a question what could be the architectural changes in case DNS being part of a separate machine ? does that machine also requires ocp network ? and do we need to update api, api-int, ocp-svc and * records to be pointing to external IP of machine having loadbalancer ?

[@ankitbansal001]

[@danp1975]

Thanks for sharing this fantastic tutorial! I hope to try it myself. I do not have vmware esxi so would virtualbox or Hyper-V be an acceptable substitute?

[@czerogr]

Hi @ryan great tutorial! One question why did you use baremetal insteand of esx/vsphere provision?

[@RyanHay]

Hey @czerogr, thanks! 2 reasons; firstly, I just wanted to explore a lot of the things the Installer Provisioned Infra (IPI) method was doing behind the scenes. Secondly, because of system resources... The host I was using only has 64GB of RAM and the vCenter Server required for the vSphere install I think at minimum takes up around 12GB of RAM which starts to take away from my already under spec'd master and worker nodes.

[@matthewmiller6068]

I'm not sure that last remark about shutting down and start any time you like is accurate. I've experienced several times where a cluster is powered down for a couple weeks and then when you go to resume messing with it everything is badly broken because all the certificates have expired. Looks like they may only be good for about a month so if you shut it off just before whenever it renews until they expire it leaves you with a pumpkin.

[@RyanHay]

Hey Matthew. As per the documentation As of OpenShift Container Platform 4.4.8, the cluster can automatically recover from expired control plane certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. To do that in bulk you can run: "oc get csr -ojson | jq -r '.items[] | select(.status == {} ) | .metadata.name' | xargs oc adm certificate approve".

[@codingwithcodi]

Hi Ryan, this is very helpful! Thank you! Are there plans for you to step through the creation of the Openshift UI for your CRs deployed by your custom Operators, using Spec Descriptors? If not, I'd love to see it! Subscribed! (See: Declarative Dynamic UI for your Operator)

Hello, i am not sure what is wrong, but the farest I have gone is when bootstrap is ready but the controll plane nodes are going DOWN and UP. I have restarted the procedure at least 6 times from scratch. At one point I have realized the ocp-svc node has different timezone than the bootstrap and controll plane nodes hence the certificates generated by the installer on the svc node are different and bootstrap and controllers failing. After fixing this, API is still not stable. Don't have a clue what is wrong. Just while I have been typing the API bootstrap and one controller came UP, but after copule of minutes they usually go DOWN again. Never seen full green by all 3 cp nodes both API and config backend.

Hi Ryan, I’ve done this following your instructions a couple of times now. Thank you! One bottleneck I’ve found is that after the initial reboot the masters and bootstrap nodes do a lot of downloading from the internet while provisioning. So much so, it consumes most of our bandwidth! We have a need to be able to setup and tear down these clusters on an adhoc basis. It’s obvious that RHCOS has a lot of things it needs to download from the internet after grabbing the image locally. Is there a way I can download those dependencies to location on my local network, saving RHCOS having to always go out to the internet to download?

Hi Vadim, I have ESXi booting off a USB on a Dell t140. I just connect to that host from my Mac. It has 64GB RAM, 2TB HDD & 6 core CPU @3.5GHz.
