System requirements

Verify that your system meets these requirements:

Minimum system requirements

Component	Requirement
Nodes	One Linux/AMD64 worker node, running Kubernetes 1.21 - 1.24 1
Kubernetes command line tool	kubectl
Kubernetes configuration files	kubeconfig Component necessary for accessing the Kubernetes cluster. Note If you are installing MSR 3.0.x on an MKE Kubernetes cluster, you must download the MKE client bundle to obtain the kubeconfig file.
Certificate management	cert-manager installed on the cluster Minimum required version: 1.7.2
Image metadata storage	One Kubernetes persistent volume 2 that supports the ReadWriteOnce volume access mode, or a StorageClass that can provision such a volume
Image data storage	Use any of the following: One Kubernetes persistent volume 2 that supports the ReadWriteMany volume access mode, or a StorageClass that can provision such a volume One cloud object storage bucket, such as Amazon S3
Image-scanning CVE database	A PostgreSQL server with sufficient storage for a 24 GB database. This can be either: An MSR-deployed dedicated PostgreSQL server, an option that requires: Postgres Operator installed on the cluster Minimum required version: 1.7.1 4 GB of RAM and 1 vCPU available, for reservation on a Kubernetes worker node One Kubernetes persistent volume 2 with 24 GB of available storage that supports the ReadWriteOnce volume access mode, or a StorageClass that can provision such a volume An existing PostgreSQL server with sufficient storage for a 24 GB database

Recommended system requirements

Component	Requirement
Nodes	Three Linux/AMD64 worker nodes, running Kubernetes 1.21 - 1.24 1
Kubernetes command line tool	kubectl
Kubernetes configuration files	kubeconfig Component necessary for accessing the Kubernetes cluster. Note If you are installing MSR 3.0.x on an MKE Kubernetes cluster, you must download the MKE client bundle to obtain the kubeconfig file.
Certificate management	cert-manager installed on the cluster Minimum required version: 1.7.2
Image metadata storage	Three Kubernetes persistent volumes 2 that support the ReadWriteOnce volume access mode, or a StorageClass that can provision such volumes
Image data storage	Use any of the following: One Kubernetes persistent volume 2 with 25 - 100 GB of available storage that supports the ReadWriteMany volume access mode, or a StorageClass that can provision such a volume One cloud object storage bucket, such as Amazon S3, with 25 - 100 GB of available storage
Image-scanning CVE database	A high availability PostgreSQL server with sufficient storage for a 24 GB database. This can be either: An MSR-deployed dedicated PostgreSQL server, an option that requires: Postgres Operator installed on the cluster Minimum required version: 1.7.1 Two Kubernetes nodes, each with 4 GB of RAM and 1 vCPU available for reservation Two persistent volumes 2, each with 24 GB of available storage, that support the ReadWriteOnce volume access mode, or a StorageClass that can provision such volumes An existing high availability PostgreSQL server with sufficient storage for a 24 GB database, which supports synchronous replication

Postgres Operator up through 1.8.2 uses the PodDisruptionBudget policy/v1beta1 Kubernetes API, which is no longer served as of Kubernetes 1.25. As such, various features of MSR may not function properly if Postgres Operator 1.8.2 or earlier is installed alongside MSR on Kube v1.25 or later.
