You are using Kubernetes in AWS. When using a kubectl command you get this error: "Connection error: Unable to connect to the server: getting credentials: exec: exit status 1 ... Could not get token: AccessDenied: Access denied"
What should you do?
Possible Solution #1
Was the user who created the Kubernetes cluster a different user from the user that is configured with your AWS CLI? Configure your AWS CLI to be the same user as the user that created the cluster. Then try the command again.
Possible Solution #2
Check your Security Groups. Is there an AWS firewall rule blocking connectivity?
Possible Solution #3
Has an Amazon Role been created? If not and you need assistance with this, see this posting.
Possible Solution #4
To ensure you have the correct AWS access key and secret key ID, create a new cluster with your AWS CLI credentials.
The command will look something like this (replace "contint" with the name you want to give your cluster):
aws eks create-cluster --name contint --role-arn arn:aws:iam::123456789:role/foobar --resources-vpc-config subnetIds=subnet-87cb36dd,subnet-2e1ba163,subnet-d355a3c1,securityGroupIds=sg-33e3abbe
The hyperlink in prerequisite ii can help you determine the "arn.../foobar" value. If you do no know what subnet IDs or security group IDs to use, try these commands if you already have an EKS cluster running:
aws eks list-clusters
aws eks describe-cluster --name contint # where "contint" is the name of the cluster that the above command produces
