subnet ID "subnet-11111111" is not the same as "subnet-22222222"

Given a config file specifying subnets for a VPC like the following:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  name: test
  region: us-east-1

vpc:
  subnets:
    public:
      us-east-1a: {id: subnet-11111111}
      us-east-1b: {id: subnet-22222222}
    private:
      us-east-1a: {id: subnet-33333333}
      us-east-1b: {id: subnet-44444444}

nodeGroups: []

An error subnet ID "subnet-11111111" is not the same as "subnet-22222222" means that the subnets specified are not placed in the right Availability zone. Check in the AWS console which is the right subnet ID for each Availability Zone.

In this example, the correct configuration for the VPC would be:

1
2
3
4
5
6
7
8
vpc:
  subnets:
    public:
      us-east-1a: {id: subnet-22222222}
      us-east-1b: {id: subnet-11111111}
    private:
      us-east-1a: {id: subnet-33333333}
      us-east-1b: {id: subnet-44444444}
