Building a Fully Routed Kubernetes Cluster with Calico CNI | Part 1: Cluster Setup & BGP Routing

[@OrgNetworks]

I got bird router running and all connections established in calico, thanks again.

[@LinuxCloudHacks]

Fantastic!

[@nidaldarwish9849]

amazing demo! please continue and add another demo about how to migrate from Weav network to Calico

[@LinuxCloudHacks]

Thanks! Will do! Do you have on-prem deployment? Are you interested in overlay or routed network? How do you handle load balancing? Just asking to see what can be interesting.

[@nidaldarwish9849]

@@LinuxCloudHacks Actually I am planning to have an on-prem cluster, and regarding the load balancer I have an idea to use an external load balancer like HAProxy, do you think it is a good idea to have such a load balancer?

¡Gracias! Amazing presentation 👏

[@LinuxCloudHacks]

Thank you too! Please let me know if there are any topics that you are interested in or have any questions! Have a great day!

[@eldarmustafayev7782]

amazing. please add more calico deep dives.

[@LinuxCloudHacks]

I'm glad you liked it! Part 2 (load balancing and traffic policies) is on the way!

[@robertscott5535]

Well done!

[@LinuxCloudHacks]

Thanks! Later today there should be part two. Stay tuned.

[@OrgNetworks]

Hello and thank you for this video. I can't seem to find part:2 of this series. Could you please link it if it exists? Thank you!

[@LinuxCloudHacks]

Hello! Video should be published this Sunday/Monday. Just need to find some time to finish edit. Stay tuned!

[@OrgNetworks]

@@LinuxCloudHacks Awesome, thanks! Also, another great video would be how to set up non-host node for calico. I was able to do it but I am not sure it is setup correctly to be used appropriately. Documentation isn't very helpful on checking if it is working properly. Thanks again for your videos!

[@LinuxCloudHacks]

Certainly. Great idea for a video. Will definitely create one. First I need to cover ebpf, networking policies, traffic encryption and then move to more advanced topics.

Should Bird BGP VM be on the same network as our k8s nodes?

[@LinuxCloudHacks]

Technically BGP routers do not need to be directly connected as they use TCP to communicate. There can be multiple hops in-between. Although for simplicity of configuration, stability, security etc. it's best to have them directly connected (one of the interface of the VM to be on the k8s network).

[@layalsadek935]

Also how do you know the AS numbers that you mentioned at minute 13:00?

[@LinuxCloudHacks]

Like in RFC1918 (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) you have private IPs for your own internal use that are not routed outside of your network, in BGP you have private BGP AS ranges that you can use and they are not advertised to the outside. It's called BGP Private AS Range and they are AS 64512 to 65534 and 4200000000 to 4294967294.
