We are in the middle of switching to custom networking, with a non routeable subnet for pods and routeable for nodes. Only concern is how would fargate deal with that, wasn't able to find docs explaining that bit...

Why do we need to reserve 1 ip for the node in the ENI? What do we need to do about ?

This was wonderful. Is there a reason the default is the default? History? I feel like at work GKE defaults to the analogy of prefix mode?

@ContainersfromtheCouch Жыл бұрын

Prefix delegation wasn’t available in VPCs at launch and Individual IP assignment is more flexible because you don’t need continuous CIDR blocks available

could you make a video how to install calico or/and cilium on eks

@ContainersfromtheCouch Жыл бұрын

The official AWS docs is the best place to get that info and make sure it’s up to date

justin is there any chance you make a series about Kubernetes troubleshooting

@ContainersfromtheCouch Жыл бұрын

What type of troubleshooting would you want? I have blogs about it in this series thenewstack.io/living-with-kubernetes-12-commands-to-debug-your-workloads/

@elabeddhahbi3301 Жыл бұрын

@@ContainersfromtheCouch I believe that the series would be more valuable if it includes real-world scenarios that you have encountered, along with your approach to resolving them. Can you please provide some examples of the most common Kubernetes problems you have faced and how you tackled them,

Good idea. I’ll think about it. In the mean time I recommend you check out @rawkode and Klustered videos
