OpenShift Bare Metal LoadBalancer Services with MetalLB

In this video I show you how to add MetalLB to your non-Cloud OpenShift cluster so you can effectively use the LoadBalancer service type just like you would in the Cloud.
Setting up MetalLB means you can spend less time dealing with NodePorts and perhaps more importantly ensure that all your load balancing configuration stays within the cluster as a single source of truth just like it would with a cluster running in the Cloud.

Very well explained. Waiting for your Openshift Service Mesh video.

Would be cool to see you enable KubeVirt as well in a future video.

Definitely, Ill take a look and push it to the top of the list.

HI , can you help how to configure MFA (Multi factor authentication ) like keycloak in in openshift 4.14

Hi Ryan, Thank you for the great video. I am trying to access the Database from outside of the OpenShift network via JDBC connection but it always fails. is there anyway we can make the pod taking to external IP (same router ip) ?

[@RyanHay]

Can you try using a NodePort and then the IP of any of the worker nodes?

[@krishnachinnasamy2764]

@@RyanHay Sure Ryan. Thank you for the reply. I will try it out .

[@krishnachinnasamy2764]

@@RyanHay I have changed the type to NodePort in Service but I couldn't change the IP address.

Nice one Ryan. Could you record a video on ocp 3 to ocp 4 migration?

[@RyanHay]

Thanks Mustufa! Ill look into it, not sure if I have enough system resources to run two clusters side by side.

cool&perfect👌👌👌

Is there a way to automate binding the app route to the external vip? Do I need a dns server for that or I have to add static dns in my router or local hosts of the app route to point to the ext vip for each app?
I followed your setup so I (hopefully) have an identical cluster environment (and I like liverpool and mo salah too lol). Thank you so much!

Hey Islam, haha, the king! I believe each of the 3 options you listed will work. On my home network I just use my local /etc/hosts file because I only need to keep one machine updated to point to the proxy. If I had more computers to keep in line I would probably expose the DNS running on the services node to the LAN network and configure my LAN comps to check that DNS as well.
