Solution Verified - Updated -

Issue

  • When pulling a container image from "registry.connect.redhat.com", this fails with the following error message:

    Failed to pull image "registry.connect.redhat.com/seldonio/seldon-core-operator-bundle@sha256:0a179578abb46e9a2ea827374cdf3787f1020892cc589073ab8962f5c7a57368": rpc error: code = Unknown desc = Error parsing image configuration: Get "https://rhc4tp-prod-z8cxf-image-registry-us-east-1-evenkyleffocxqvofrk.s3.dualstack.us-east-1.amazonaws.com/docker/registry/v2/blobs/sha256/95/95484b2371976b3a6485b06ba75ba2e1cdda038f137af1e6085cca390c75ab1f/data?X-Amz-Algorithm=AWS4-HMAC-SHA256&[..]": net/http: TLS handshake timeout

    According to the following Solution, AWS S3 does not need to be allowed on the firewall: Applying IP address filtering to Red Hat Container Registries. Why are we seeing the error above?

  • Pulling a container image from "registry.connect.redhat.com" redirects to AWS S3, is this expected?

Environment

  • OpenShift Container Platform 4.6 and later
  • Container Registry registry.connect.redhat.com
