[Bug] eksctl no EC2 IMDS role found, operation error ec2imds while running in docker container

[cantonnetwork-infstones]

What were you trying to accomplish?

Any eksctl get command fails. Did not test other commands. This works well on the same EC2 instance where we are running the docker container.

eksctl get iamserviceaccount --cluster <cluster-name>  # or any iamserviceaccount command

Expected Output:

app-ns		app		arn:aws:iam::xxxxx:role/xyz

What happened?

Any eksctl version higher than v0.185.0 does not work in a container while v0.185.0 works. We get the below error for anything above v0.185.0

Error: could not create cluster provider from options: checking AWS STS access – cannot get role ARN for current session: operation error STS: GetCallerIdentity, get identity: get credentials: failed to refresh cached credentials, operation error STS: AssumeRole, get identity: get credentials: failed to refresh cached credentials, no EC2 IMDS role found, operation error ec2imds: GetMetadata, canceled, context deadline exceeded

The following command does give proper output

aws sts get-caller-identity
{
    "UserId": "AROATxxxxxx:botocore-session-12345",
    "Account": "123456",
    "Arn": "arn:aws:sts::123456:assumed-role/xxxx/botocore-session-12345"
}

How to reproduce it?

To reproduce run any version of eksctl above v0.185.0 in a docker container.

~/aws/config is configured as follows

[default]
region = us-east-1

~/.aws/credentials is configured as follows

[app-01]
region=us-east-1
role_arn=arn:aws:iam::12345:role/app-01
credential_source=Ec2InstanceMetadata
duration_seconds=3600

export AWS_PROFILE=app-01

eksctl get iamserviceaccount --cluster xyz
