Hi,
Could you try rerunning with RUST_LOG=debug
and LANCE_LOG=debug
env var? This should give us more information on why the credential fetching failed.

Will do. To be clear do you mean something like this?
import os
LANCE_ROOT = 's3://somewhere'
os.environ["RUST_LOG"] = "debug"
os.environ["LANCE_LOG"] = "debug"
import lancedb
def lance_connect():
return lancedb.connect(LANCE_ROOT, region=os.environ.get("AWS_DEFAULT_REGION"))
I think what you posted will work. If not, could you try running with RUST_LOG=debug LANCE_LOG=debug python ./my_script.py
?

Cool, ill let you know. ill try the first thing first. Its on EKS so there is a bit of setup and build time involved...
Ok @chebbyChefNEQ for some reason the os.env did not work but I could export the 2 ENV settings in my Dockerfile
I can see what its doing now so many thanks for this info! it seems to assume an AWS config is in $HOME which I would not have thought is the only way to setup the creds (I realize i can mount some creds there if I need to). Incidentally, i'm not so sure the notion of profiles makes sense in this K8s context . Anyway here are the logs;

The credential provider chain could not talk to IMDS. This like most likely a configuration issue in the node or cluster networking.
Instance MetaData Service (IMDS) is what provides aws creds inside EC2. Due to security reasons, AWS limit the packets from the service, at 169.254.169.254
, to 1 hop TTL. In container networking this blocks containers from talking to IMDS.
[ IMDS ] -- [ EC2 ] -- [ Container ]
^^^ this is two hops.
While EKS default to two hops these days, many things could block access, like calico policy, or using IMDSv1 on the host.
Greetings, Locally I can connect Lance to s3 storage using my ENV AWS keys but on Kubernetes AWS/EKS im running into an unexpected issue. The error i get is this one
The reason why this is unexpected for me is that on EKS/K8s I typically run many services that use the AWS Creds/Service Account on the nodes such that I typically do not need to specify additional keys when running on pods in those nodes - My pods load a default region via env too.
Looking through the lance code im not 100% sure if there is definitely a need for me to do something extra here to specify credentials for AWS and if so, what are my options for passing creds. Is there anything i should load into the env? Do i need to configure something that I have not thought of in the connect constructor??
Any pointers appreciated.
Cheers
