it could be many things .. I'd say it's probably best to open a support case with Red Hat and let them guide you though the troubleshooting - support.redhat.com

Thanks for your comment. This video has been a biggest rabbit hole I have worked on so far. It's so easy to get into details that could mud the big picture. There is a reason why it ended up being the longest video I have done. I'd love to go into network flows, however I don't foresee it happening soon. I have some other cool networking topics to cover first .. like BGP integration (current and upcoming) and bunch of other stuff.

So nice of you

I appreciate it!

Hi @ssaa3209. Thanks for your comment. Setting platform to None is supported, however it does come with some small tradeoffs not described in this video like no machine-api or disabled metal3. The second one can be added just fine day2. I think it's totally worth it .. I have been running this architecture for few months with very little sacrifices. One lessons learned is to not create MCP for each AZs unless you are running a large cluster. It's not best fit for everything. I generally still use a mix of distributed and regular clusters that are running in the same layer2 and then abstract them with something like ArgoCD or ACM. There is pros and cons to everything. As of ironic LB, I have created it but it's not even used in my deployment. There is a very niche use case for this. Not even RHOSO would use that as far as I can tell. Just disregard it and sorry for confusion.

@@TrustedAdvisor-tk8lj PLease Can you share the Full used Install-config.yaml file as well as the agent-config.yaml just to make sure that i have all the populated settings correct !!!!, another question in another situation if i need to segregate the LB between the HA LB and the KeepAlived can i do it and in this case what is the Config inside the install-config.yaml ??? how it will be Entered !!!!!!!!

I have just added the config into the description of the video. With the external LoadBalancer you will no longer need Keepalived

Here is a cool video for my good friend Leif for showing some POC around this -> kzbin.info/www/bejne/hJmkn2Sjbq97gtE .. I'd love to make a video myself around it, but there is at least few more other ideas that I'd like to record first. Thanks for your comment.

Every software is locking you in, but OpenShift I'd argue to a lesser degree. You could move to other Kubernetes distribution relatively easy. Also there is a OKD option if you decide to not pay a vendor for support. Thanks for your comment.

OKD? BTW, one can simply use upstream k8s. Works like a charm on metal.

@fio_mak OKD is an upstream, unpaid version of Openshift. No vendor support, though, just like a plain K8s. Going with the upstream Kubernetes is just fine as long as you can cover the talent that will manage it. Thanks for your input.

Hi. Are you abstracting vsphere volumes with odf? I think it should work, but there would probably be some compromising like multiplication of replicas. Also probably some performance penalties. Probably best to reach out to your Red Hat rep for help.

Hi, are you using dvswitch or something else like nsx? If your network is already tagged at the hypervisor level then you should be able to just assign appropriate IPs and set up gateway and dns server. It's hard to help without all the details. Good luck!

Yes, that is a great summary. you got it

Glad you enjoyed it!

for disconnected you might want to consider a different installer. I recommend Agent Based

Thanks, @kevintunks739!

Thanks. DR requires at least couple of clusters to demonstrate. Hence, it's taking me a while to put it together.

Thanks Jean!

Interestingly enough I just worked on somewhat similar use case. Setting platform to none allowed me to bring my own load balancer - I have personally used HA Fortigate firewalls to also act as my load balancers. This is fairly fresh in my head so I would really want to make a video on it. It's hard for me to find a time these days

I am not sure. You would have to reach out to your Red Hat rep.

I don't have instructions for that but it should be somewhat similar.

I'd like to create another video with portworx, but didn't really have opportunity to do so.

Hi. Both Assisted and Agent Based would allow you to bond any interface you need - including the OCP base network. Just use the yaml editor. Example: interfaces: - name: bond0 type: bond state: up ipv4: address: - ip: X.X.X.X prefix-length: 24 dhcp: false enabled: true link-aggregation: mode: 802.3ad port: - ens1f0 - ens1f1 mtu: 9000

@@TrustedAdvisor-tk8lj Thanks, this yaml option was not available in previous version. Looks good

the example here is not disconnected .. you would need to sync the image registries, create a mirror for disconnected and reference it in your configuration file

thank you for your comment, it's on the list .. just super hard to find time.

thanks. Yeah, it's on the list .. just super hard to find time.

The video or the platform ?

What hardware are you booting this on? It might be worth opening a support case with Red Hat.

Thanks for your comment. The benefits for the "all on public cloud" use case are: - ability to overcommit on resources (and not shared with others) - potential cost savings vs EC2 - 3rd party Software Defined Storage - and all the benefits that comes with it (live migration across AZs, DR etc) - arguably the best Kubernetes distribution to share between containers and VMs with all the awesome features built in - unlimited RHEL running on top (cost savings) There are tradeoff like increased complexity - since you are managing 2 stacks and the cost for smaller OCP clusters and no overcommit it going to be higher.

@TrustedAdvisor-tk8lj thanks for the answer. I am convinced :) Please keep it up sharing these contents. I like how you include, already in your video, many valid points we ask ourselves when choosing the best strategy. Have a good day.

@@Meme-2m2e - :-) .. I am glad you liked the video. Thanks for your feedback.

Thanks for the feedback. DR is quite high on my list to cover.

Thanks. I really need to get on that.

Thanks. Portworx is on my wishlist, although it's a rather long list :-)

@@TrustedAdvisor-tk8lj share the list 😃; Will help you prioritize

Hi. By default, Openshift deploys haproxies to handle the ingress. There is an official doc for this in here -> docs.openshift.com/container-platform/4.14/networking/ingress-operator.html . I have also seen Openshift users deploying custom workers with nginx as an ingress controllers

Hi, yeah the docs are minimal for this. I have just used the UPI process to add nodes to the existing cluster. I know Red Hat engineering is working on a more streamlined process for expanding the cluster, but that is not yet available, so for now, UPI is the only way I am aware of.

​@@TrustedAdvisor-tk8lj Yes, thats truely a pity imho. Assisted installer otoh is not as flexible and more GUI-oriented than Agent-based installer, but you can easily add nodes afterwards using the Assistes installer.

@@TrustedAdvisor-tk8ljHi thanks for the amazing video. Im new to Openshift and having the same issue: Using Agent Based Installer to deploy cluster and want to expand more worker node. I saw you mentioned UPI, can you provide some guideline and links for me how to do it? I really have no idea and want to get some help!

@@louis417asdo - I haven't used it yet, but someone pointed me out to this cool project -> github.com/openshift/installer/blob/master/docs/user/agent/add-node/add-nodes.md .. let me know if it works for you

Thank you. I am glad you found it helpful.

it's definitely possible. I don't have a video for that yet.

Thanks for watching. I am glad you liked it. I'd love to make a DR video. I have a few more in the pipeline, but will get into DR as soon as I can.

ODF can provide a file storage, but not nfs mountable. It also consumes just straight up local storage of your servers and turns them into HA cluster. I personally use OpenStack manila project for providing NFS capabilities with Ceph.

I am glad you liked it and thanks for re-sharing Nate.

Thanks Lee. I am glad you liked it. I appreciate the comment!

I am glad you enjoyed the videos. There is more then one way to learn. When I started, I ended up purchasing some second hand hardware from ebay and built a home lab. For me the hands on experience is how I learn the quickest.

I am glad you liked it!

Can't wait to see what you are cooking there. Let's do something together.

I have just posted assisted installer video earlier today and planning to get the agent based installer video out next week. I'd like to do UPI for completeness, but I am a bit time constrained having a daytime job and all. I'll do my best but probably not anytime soon. Sorry for that.

Thanks! I wish all the Red Hat installers were this easy :P

@@TrustedAdvisor-tk8lj you and me both 😉
