17장. Configuring artifact types


As a Red Hat Quay administrator, you can configure Open Container Initiative (OCI) artifact types and other experimental artifact types through the FEATURE_GENERAL_OCI_SUPPORT, ALLOWED_OCI_ARTIFACT_TYPES, and IGNORE_UNKNOWN_MEDIATYPES configuration fields.

The following Open Container Initiative (OCI) artifact types are built into Red Hat Quay by default and are enabled through the FEATURE_GENERAL_OCI_SUPPORT configuration field:

Additionally, Red Hat Quay uses the ZStandard, or zstd, to reduce the size of container images or other related artifacts. Zstd helps optimize storage and improve transfer speeds when working with container images.

Use the following procedures to configure support for the default and experimental OCI media types.

17.1. Configuring OCI artifact types

Use the following procedure to configure artifact types that are embedded in Red Hat Quay by default.

Prerequisites

  • You have Red Hat Quay administrator privileges.

Procedure

  • In your Red Hat Quay config.yaml file, enable support for general OCI support by setting the FEATURE_GENERAL_OCI_SUPPORT field to True. For example:

    FEATURE_GENERAL_OCI_SUPPORT: true

    With FEATURE_GENERAL_OCI_SUPPORT set to true, Red Hat Quay users can now push and pull charts of the default artifact types to their Red Hat Quay deployment.
