Chapter 1. Prerequisites for Red Hat Quay on OpenShift
Here are a few things you need to know before you begin the Red Hat Quay Operator on OpenShift deployment:
- OpenShift cluster: You need a privileged account to an OpenShift 4.5 or later cluster on which to deploy the Red Hat Quay Operator. That account must have the ability to create namespaces at the cluster scope.
Resource Requirements: Each Red Hat Quay application pod has the following resource requirements:
- 8Gi of memory
- 2000 millicores of CPU.
The Red Hat Quay Operator will create at least one application pod per Red Hat Quay deployment it manages. Ensure your OpenShift cluster has sufficient compute resources for these requirements.
Object Storage: By default, the Red Hat Quay Operator uses the
ObjectBucketClaimKubernetes API to provision object storage. Consuming this API decouples the Operator from any vendor-specific implementation. OpenShift Container Storage provides this API via its NooBaa component, which will be used in this example. Otherwise, Red Hat Quay can be manually configured to use any of the following supported cloud storage options:- Amazon S3 (see S3 IAM Bucket Policy for details on configuring an S3 bucket policy for Red Hat Quay)
- Azure Blob Storage
- Google Cloud Storage
- Ceph Object Gateway (RADOS)
- OpenStack Swift
- CloudFront + S3
