Question

Can i use ipv6 on kubernetes cluster managed by DO?

DigitalOcean Managed Kubernetes

Hello everyone,

I have been using Digital Ocean services for several years, recently there was a need to migrate some services to Docker, after studies I decided to use Kubernetes.

One of the factors was the availability of the service here at Digital Ocean, but there is a need to use a Load Balancer to be able to publish Ingress correctly.

Until I accepted that, 10 $ will not stop the project. However, DO Load Balancers do not support IPv6, so my services will not be accessible via IPv6?

Can anyone help me understand this? How can I use Kubernetes, Load Balancer and IPv6 in my services? Is load balancer really required to create the Ingress (nginx, traefik, etc)?

Tks

So, just to update everyone, I would like to inform you that I was able to use IPv6 and IPv4 with Kubernetes and everything is working normally. Just visit https://cloud.google.com/kubernetes/ and upload your infra on Google. It probably works on Amazon too, unfortunately it doesn’t work here at DO. Only if you want to manually “raise” your infra, through Kubespray or by commands.

IPv4 has run out and the whole world is suffering because of this, internet providers need to make CGNAT to be able to provide ipv4 to customers, exchange equipment, etc. IPv6 should be a mandatory requirement for any service. But I understand that migrating everything to a new technology (ipv6) is difficult, especially a technology created in the last century (1998), I understand that there is little time to be able to deploy it.

I left with a broken heart, but I’m already liking Google, I recommend it to everyone who wants to use Kubernetes and want IPv4 and IPv6 natively.

Regards

I wish there was a better option. I just did a pricing calculation on google cloud. I have a tiny little kubernetes cluster with two instances, a load balancer and about 15gb volume storage. It comes down to about $40/month on DO but about $85/month on GKE. I want IPv6 but for right now I don’t think I want it enough to more than double my costs per month.
