UnsupportedAvailabilityZoneException: lack of capacity to support cluster

[niksrc]

unable to create cluster control plane: UnsupportedAvailabilityZoneException: Cannot create cluster '****-**' because us-east-1c, the targeted availability zone, does not currently have sufficient capacity to support the cluster. Retry and choose from these availability zones: us-east-1a, us-east-1b, us-east-1d

This appears to be a well known-issue with EKS currently (see #75 (comment)), I am not sure how eksctl could possibly address this – wdyt?

[niksrc]

Thanks for the quick reply. I'm wondering what eksctl does differently as i am able to create a cluster from the console every time in the same region.

See this issue coreos/coreos-kubernetes#442 where @mumosho suggests letting cloudformation decide which availabilty zone to choose for a user.
Here is the corresponding gist https://gist.github.com/mumoshu/d375a37a87d09ecdc0cc0d1be322e628

@niksrc thanks for your suggestion, I will definitely look into this. Have you been able to create a cluster with eksctl after all or still no dice?

[errordeveloper]

So the gist you've pointed at shows exactly the same thing that we already have:

https://github.com/weaveworks/eksctl/blob/b7c60b657a552c2b8e7e2f4e17686786498fae00/pkg/eks/assets/1.10.0/2018-05-09/amazon-eks-vpc-sample.yaml#L81-L99

https://github.com/weaveworks/eksctl/blob/b7c60b657a552c2b8e7e2f4e17686786498fae00/pkg/eks/assets/1.10.0/2018-05-09/amazon-eks-vpc-sample.yaml#L101-L119

I am not sure what we can do better, but we also need to keep #101 in mind.

[niksrc]

@errordeveloper i was able to create the cluster by hard coding the index of the subnet in the template files and rebuilding eksctl. I don't think we can do anything to fix this unless aws provides an api for availability detection for a region.

Thanks for looking into this.

[errordeveloper]

@niksrc did you do something similar to what @jorihardman did in https://github.com/swipesense/eksctl/commit/ca185e446da624f0f65b27b57dd121d54adbe7c9? I think we should be able to incorporate something similar to that, but we might want to take it out of CloudFormation and also fix #101.

[errordeveloper]

I'd rather keep this issue open for now.

[niksrc]

@errordeveloper yes, i did the same thing, and please let me know if you need any help from me.

[errordeveloper]

@niksrc we are working on a fix in #124, testing would be very helpful, we will let you know once it's ready to test (it's not yet).

[errordeveloper]

@niksrc we have merged a fix for this in #124. I've tagged 0.1.0-beta.2 and binaries should be available shortly – please let us know if it works for you!
