If you are using Pachyderm version 1.9.7 or earlier, go to the documentation archive.

Deploying Pachyderm On-Premises With Non-Cloud Object Stores

Coming soon. This document, when complete, will discuss common configurations for on-premises objects stores.

General information on non-cloud object stores

Please see the on-premises introduction to object stores for some general information on object stores and how they're used with Pachyderm.

S3 API Signature Algorithms and Regions

The S3 protocol has two different ways of authenticating requests through its api. S3v2 has been officially deprecated by Amazon, so it's not likely that you'll run into it. You don't need to know the details of how they work (though you can follow these links, S3v2 & S3v4, if you're curious), but you may run into issues with either mismatch of the signature method or availability regions.

If you have trouble getting Pachyderm to run, check your Kubernetes logs for the pachd pod, Use kubectl get pods to find the name of the pachd pod and kubectl logs <pachd-pod-name> to get the logs.

If you see an error beginning with

INFO error starting grpc server pfs.NewBlockAPIServer

It could have either of two causes.

Availability Region Mismatch

If the error is of the form

INFO error starting grpc server pfs.NewBlockAPIServer: storage is unable to discern NotExist errors, "The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'z1-a'" should count as NotExist
It may be a known issue with hardcoded region us-east-1 in the minio libraries. You can correct this by either using the --isS3V2 flag on your the pachctl deploy custom ... command or by changing the region of your storage to us-east-1.

Signature version mismatch

You're not likely to run into this in an on-premises deployment unless your object store has deliberately been set up to use the deprecated S3v2 signature or you are running your on-premises deployment against Google Cloud Storage, which is not recommended. See Infrastructure in general.

You'll need to determine what signature algorithm your object store uses in its S3-compatible API: S3v2 or S3v4. If it's S3V2, you can solve this by using the --isS3V2 flag on your the pachctl deploy custom ... command.
