Prerequisites to deploy YBA on a VM
When installing YugabyteDB Anywhere (YBA) on an existing Kubernetes cluster, you will install YBA onto a Kubernetes pod using Helm charts.
In addition to the Kubernetes admin account and other Kubernetes permissions, your Kubernetes cluster(s) must meet the following hardware and software requirements.
Hardware requirements
Each Kubernetes node in the Kubernetes cluster must meet the following requirements:
- 5 cores (minimum) or 8 cores (recommended)
- 15 GB RAM (minimum)
- 100 GB SSD disk (minimum)
- 64-bit CPU architecture
Software requirements
The Kubernetes cluster and nodes must meet the following software criteria:
- Operating System: any Linux OS
- Kubernetes cluster and Helm version:
- Kubernetes 1.22+
- Helm 3.11.3+
- For OpenShift, versions 4.6+ of the OpenShift Container Platform (OCP) are supported
- Additional software or information
- A Kubernetes Helm secret (which acts like a license key)
The YugabyteDB Anywhere Helm chart has been tested using the following software versions:
- Kubernetes - 1.22 to 1.25
- Helm - 3.11.3
To get the secret, contact your YugabyteDB representative in Sales or Support. It allows download access to the YBA binaries from the YugabyteDB Helm repository.
Outbound internet access
Verify that your Kubernetes cluster nodes have Internet access and therefore can pull container images from the YugabyteDB quay.io container registry.
If the Kubernetes cluster nodes cannot do this, copy the images to your internal registry by following instructions provided in Pull and push YugabyteDB Docker images to private container registry.
High availability deployments
If you plan to deploy YBA in active/passive high-availability mode, you need two independent deployments of YBA in two separate pods; one for the active YBA instance, and another for the passive YBA instance.
If the two pods are on separate Kubernetes clusters, be sure that the pods are exposed through LoadBalancers or Egress so that they can communicate with each other. Separately, you might need to ensure that both YBA HA pods can communicate with all the YugabyteDB database pods. See Networking requirements for Kubernetes for more details.
