; }; noindex: true Determining the resource requirements for a Kubernetes cluster depends on a number of different factors, including what type of applications you are going to be running, the number of users that are active at once, and the workloads you will be managing within the cluster. *Data Science & AI Workbench’s performance is tightly coupled with the health of your Kubernetes stack*, so it is important to allocate enough resources to manage your users workloads. Anaconda’s hardware recommendations ensure a reliable and performant Kubernetes cluster. However, most requirements are likely to be superseded by the requirements imposed by your existing Kubernetes cluster, whether that is an on-premise cluster that is configured to support multiple tenants or a cloud offering. To install Workbench successfully, your systems must meet or exceed the requirements listed below. Anaconda has created a pre-installation checklist to help prepare you for installation. The checklist helps you verify that your cluster is ready to install Workbench, and that the necessary resources are reserved. Anaconda’s Implementation team will review the checklist with you prior to your installation. ## Supported Kubernetes versions Workbench is compatible with Kubernetes API versions `1.15-1.28`. If your version of Kubernetes utilizes the API at these versions, you can install Workbench! Workbench has been successfully installed on the following Kubernetes variants: * Vanilla Kubernetes * VMWare Tanzu * RedHat OpenShift * Google Anthos * Amazon Elastic Kubernetes Service (EKS) * Microsoft Azure Kubernetes Service (AKS) * Google Kubernetes Service (GKE) * RedHat OpenShift on AWS (ROSA) Aside from the basic requirements listed on this page, Anaconda also offers [environment-specific recommendations](/docs/data-science/5.8.1/environment-prep/env-specific-reqs/main) for you to consider. ## Administration server Installation requires a machine with direct access to the target Kubernetes cluster and Docker registry. Anaconda refers to this machine as the Administration Server. Anaconda recommends that you identify a machine to be your Administration Server that will remain available for ongoing management of the application once installed. It is useful for this server to be able to mount the storage volumes as well. The following software must be installed on the Administration Server: * `Helm` version 3.2+ * The Kubernetes CLI tool - `kubectl` * (OpenShift only) The OpenShift `oc` CLI tool * (Optional) The `watch` command line tool * (Optional) The `jq` command line tool You can obtain all of the tools you need for your Administration Server by installing the `ae5-conda` environment. This environment already contains `helm`, `kubectl`, `oc`, `jq`, and a number of other useful Workbench management utilities. To install the environment: 1. [Download the environment](https://airgap-svc.s3.amazonaws.com/misc/ae5-conda-latest-Linux-x86_64.sh). 2. If necessary, move the environment to the Administration Server. 3. Open a terminal shell and install the environment by running the following command: ```sh theme={null} bash ae5-conda-latest-Linux-x86_64.sh ``` 4. Follow the prompts, then restart your terminal. 5. (Optional) Add the environment to your `PATH`. ## CPU, memory, and nodes * Minimum node size: 8 CPU cores, 32GB RAM * Recommended node size: 16 CPU cores, 64GB RAM (or more) * Recommended oversubscription (limits/requests ratio) 4:1 * Minimum number of worker nodes: 3 Minimally sized nodes should be reserved for test environments with low user counts and small workloads. Any development or production environment should meet or exceed the recommended requirements. Workbench utilizes [node labels](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/) and [taints and tolerations](https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/) to ensure that workloads run on the appropriate nodes. Anaconda recommends identifying any necessary affinity (which nodes a workload runs on based on its applied labels) or toleration settings prior to installation. ## Resource profiles Resource profiles available to platform users for their sessions and deployments are created by the cluster administrator. Each resource profile can be customized for the amount of CPU, memory, and (optionally) GPU resources available. Anaconda recommends determining what resource profiles you will require prior to installation. For more information, see [Configuring workload resource profiles](/docs/data-science/5.8.1/admin/resources/resource-profile). ## Namespace, service account, RBAC Workbench should be installed in a namespace that is *not occupied* by any other applications, including other instances of Workbench. Create a service account for the namespace with sufficient permissions to complete the helm installation and enable the dynamic resource provisioning Workbench performs during normal operation. Workbench requires more permissions than would normally be given to an application that only requires `read-only` access to the Kubernetes API. However, with the exception of the ingress controller, all necessary permission grants are limited to the application namespace. Please speak with the Anaconda Implementation team about any questions you might have regarding these permissions. The following `Role` and `RoleBinding` pair can be used to grant sufficient permissions to the Service Account. ```yaml theme={null} # Replace with the name of your service account # Replace with the namespace reserved for Workbench apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: name: namespace: rules: - verbs: [ "get", "list" ] apiGroups: [ "" ] resources: [ "namespaces", "pods/log", "events" ] - verbs: [ "create", "delete", "get", "list", "patch", "update", "watch" ] apiGroups: [ "" ] resources: [ "configmaps", "secrets", "pods", "persistentvolumeclaims", "endpoints", "services" ] - verbs: [ "create", "delete", "get", "list", "patch", "update", "watch" ] apiGroups: [ "apps" ] resources: [ "deployments", "replicasets", "statefulsets" ] - verbs: [ "create", "delete", "get", "list", "patch", "update", "watch" ] apiGroups: [ "batch" ] resources: [ "jobs", "cronjobs" ] - verbs: [ "create", "delete", "get", "list", "patch", "update", "watch" ] apiGroups: [ "extensions" ] resources: [ "deployments", "replicasets" ] - verbs: [ "create", "delete", "get", "list", "patch", "update", "watch" ] apiGroups: [ "networking.k8s.io" ] resources: [ "ingresses" ] - verbs: [ "create", "delete", "get", "list", "patch", "update", "watch" ] apiGroups: [ "route.openshift.io" ] resources: [ "routes", "routes/custom-host" ] - verbs: [ "get", "list" ] apiGroups: [ "" ] resources: [ "serviceaccounts", "roles" ] --- apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: namespace: roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: subjects: - kind: ServiceAccount name: ``` Recent versions of OpenShift no longer allow granting direct access to the `anyuid` Security Context Constraint (SCC), or any other default SCC. Instead, access grants are defined within the role. ```yaml theme={null} - verbs: - use apiGroups: - security.openshift.io resources: - securitycontextconstraints resourceNames: - anyuid ``` If you want to use the Anaconda-supplied ingress, it is also necessary to grant a small number of additional, cluster-wide permissions. This is because the ingress controller expects to be able to monitor ingress-related resources across all namespaces. The following is a minimal `ClusterRole` and `ClusterRoleBinding` pair that has grants the ingress controller sufficient permissions to run without warnings: ```yaml theme={null} # Ingress Controller Permissions apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRole metadata: name: -ingress annotations: anaconda-rbac: "true" rules: - verbs: [ "create", "delete", "get", "list"] apiGroups: [ "*" ] resources: [ "ingressclasses" ] - verbs: [ "patch", "create" ] apiGroups: [ "*" ] resources: ["events"] - verbs: ["list", "watch"] apiGroups: ["*"] resources: [ "secrets", "endpoints", "ingresses", "endpointslices", "services", "pods" ] --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: -ingress roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: subjects: - kind: ServiceAccount name: namespace: ``` If you want to use the Kubernetes Dashboard and resource monitoring services included with Workbench, you must include additional permissions for each service. You must establish permissions for *both* Prometheus *and* kube-state-metrics to utilize Worbench’s resource monitoring features. ```yaml theme={null} # Dashboard - Application kind: Role apiVersion: rbac.authorization.k8s.io/v1 metadata: name: -dashboard namespace: rules: # Allow Dashboard to get, update and delete Dashboard exclusive secrets. -

While it is *possible* to further reduce these scopes, doing so is likely to prevent normal operation of Workbench. ## Security Preparing your Kubernetes cluster to install Workbench involves configuring your environment in a way that both supports the functionality of Workbench and adheres to security best practices. Workbench containers can be run using any fixed, non-zero UID, making the application compatible with an OpenShift Container Platform (OCP) restricted SCC, or an equivalent non-permissive Kubernetes security context. This reduces the risk to your systems if the container is compromised. However, in order to enable the Authenticated Network File System (NFS) capability, allowing user containers to access external, authenticated fileshares (storage servers), user pods must be permitted to run as root (UID 0). This configuration runs containers in a privileged state to determine and assign the authenticated group memberships of the user running the container only. Once authentication is complete, the container drops down to a non-privileged state for all further execution. Please speak with your Anaconda Implementation team for more information, and to see if it is possible for your application to avoid this requirement. ## Storage A standard installation of Workbench requires two [Persistent Volume Claims](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) (PVCs) to be *statically provisioned and bound prior to installation*. Anaconda strongly recommends a premium performance tier for provisioning your PVCs if the option is available. Expand the following sections for more information about the necessary volumes: This volume contains: * Anaconda’s internal Postgres control database * Anaconda’s internal Git storage mechanism * Anaconda’s internal conda package repository If you are hosting conda packages outside of Workbench, the minimum size of your `anaconda-storage` volume must be at least *100GiB*. However, if you intend to mirror conda packages into the Workbench repository, the `anaconda-storage` volume will need to be much larger to accommodate those packages. Anaconda recommends *at least 500GiB of storage*. The `anaconda-storage` volume must support either the `ReadWriteOnce` or `ReadWriteMany` access mode. The `ReadWriteOnce` configuration requires that the `postgres`, `git-storage`, and `object-storage` pods run on the same node. This volume hosts Anaconda’s managed persistence storage. It contains: * Custom sample projects * Custom conda environments * User code and data The `anaconda-persistence` volume requires `ReadWriteMany` access. The demands on the `anaconda-persistence` volume will continuously grow with usage. Anaconda recommends you provision *at least 1TiB of storage to start*. It is possible to combine these into a single `PersistentVolumeClaim` to cover both needs, *as long as that single volume simultaneously meets the performance needs demanded by both*. The root directories of these storage volumes must be writable by Workbench containers. This can be accomplished by configuring the volumes to be group writable by a single numeric GroupID (GID). Anaconda strongly recommends that this GID be `0`. This is the default GID assigned to Kubernetes containers. If this is not possible, supply the GID within the Persistent Volume specification as a `pv.beta.kubernetes.io/gid` annotation. To ensure that the data on these volumes is not lost if Workbench is uninstalled, do not change the `ReclaimPolicy` from its default value of `Retain`. ## Ingress and firewall Workbench is compatible with most ingress controllers that are commonly used with Kubernetes clusters. Because ingress controllers are a cluster-wide resource, Anaconda recommends that the controller be installed and configured prior to installing Workbench. For example, if your Kubernetes version falls within `1.19-1.26`, any ingress controller with full support for the `networking.k8s.io/v1` ingress API enables Workbench to build endpoints for user sessions and deployments. If your cluster is fully dedicated to Workbench, you can configure the Helm chart to install a version of the [NGINX Ingress controller](https://www.nginx.com/products/nginx-ingress-controller/), which is compatible with multiple variants of Kubernetes, including OpenShift. Anaconda’s only modification to the stock NGINX container enables it to run without root privileges. Your cluster configuration and firewall settings must allow all TCP traffic between nodes, particularly HTTP, HTTPS, and the standard Postgres ports. Healthy clusters can block inter-node communication, which disrupts the pods that Workbench requires to provision user workloads. External traffic to Workbench will be funneled entirely through the ingress controller, through the standard HTTPS port `443`. ## DNS/SSL Workbench requires the following: * A valid, fully qualified domain name (FQDN) reserved for Workbench. * A DNS record for the FQDN, as well as a *wildcard* DNS record for its subdomains. Both records must point to the IP address allocated by the ingress controller. If you are using an existing ingress controller, you might be able to obtain this address prior to installation. Otherwise, you must populate the DNS records with the address after the initial installation is complete. * A valid *wildcard* SSL certificate covering the cluster FQDN and its subdomains. Installation requires both the public certificate and the private key. If the certificate chain includes an intermediate certificate, the public certificate for the intermediate is required. The *scope* of the wildcard only requires `*.anaconda.company.com` to be covered, ensuring that all subdomains under this specific domain are included in the SSL certificate and DNS configuration. * The public root certificate, if the above certificates were created with a private Certificate Authority (CA). Wildcard DNS records and SSL certificates are *required* for correct operation of Workbench. If you have any objections to this requirement, speak with your Anaconda Implementation team. ## Docker images Anaconda strongly recommends that you copy the Workbench Docker images from our authenticated source repository on Docker Hub into your internal docker registry. This ensures their availability even if there is an interruption in connectivity to Docker Hub. This registry must be accessible from the Kubernetes cluster where Workbench is installed. In an air-gapped setting, this is *required*. Anaconda provides a more precise manifest, including version numbers and the credentials required to pull these images from our authenticated repository, prior to installation. ``` ae-app-proxy ae-auth ae-auth-api ae-auth-escrow ae-deploy ae-docs ae-editor ae-git-proxy ae-git-storage ae-object-storage ae-operation-controller ae-operation-create-project ae-repository ae-storage ae-sync ae-ui ae-workspace ae-wagonwheel ae-auth-keycloak ae-nginx-ingress-v1 ae-nginx-ingress-v1beta1 postgres:16.12 ``` Docker images used by Workbench are larger than many Kubernetes administrators are accustomed to. For more background, see [Docker image sizes](/docs/data-science/5.8.1/reference/understanding-ae5#docker-image-sizes). ## GPU information This release of Workbench supports up to Compute Unified Device Architecture (CUDA) `11.6` DataCenter drivers. Anaconda has directly tested the application with the following GPU cards: * Tesla V100 (recommended) * Tesla P100 (adequate) Theoretically, Workbench will work with any GPU card compatible with the CUDA drivers, as long as they are properly installed. Other cards supported by CUDA `11.6`: * A-Series: NVIDIA A100, NVIDIA A40, NVIDIA A30, NVIDIA A10 * RTX-Series: RTX 8000, RTX 6000, NVIDIA RTX A6000, NVIDIA RTX A5000, NVIDIA RTX A4000, NVIDIA T1000, NVIDIA T600, NVIDIA T400 * HGX-Series: HGX A100, HGX-2 * T-Series: Tesla T4 * P-Series: Tesla P40, Tesla P6, Tesla P4 * K-Series: Tesla K80, Tesla K520, Tesla K40c, Tesla K40m, Tesla K40s, Tesla K40st, Tesla K40t, Tesla K20Xm, Tesla K20m, Tesla K20s, Tesla K20c, Tesla K10, Tesla K8 * M-Class: M60, M40 24GB, M40, M6, M4 Support for GPUs in Kubernetes is still a work in progress, and each cloud vendor provides different recommendations. For more information about GPUs, see [Understanding GPUs](/docs/data-science/5.8.1/reference/understanding-ae5#gpus). ## Helm charts Helm is a tool used by Workbench to streamline the creation, packaging, configuration, and deployment of the application’s configurations. It combines all of the config map objects into a single reusable package called a Helm chart. This chart contains all the necessary resources to deploy the application within your cluster. These resources include `.yaml` configuration files, services, secrets, and config maps. For customer-supplied Kubernetes environments, Workbench includes templated `values.byok.*.yaml` files that override the default values in the top-level Helm chart. These template files are heavily commented to guide you through configuring the parameters that most commonly require modifications. If Workbench is the only application present within your cluster, use the single-tenant configurations. If Workbench shares the cluster with other applications, use the multi-tenant configurations. Choose the template that applies to your setup and make additions and modifications to the file with your current cluster configurations at this time. Single-tenant clusters use the `values.byok.cluster.yaml` override file template. ```yaml theme={null} # This values.yaml template is intended to be customized # for each installation.

Within this checklist, Anaconda provides some commands or command templates for you to run in order to verify a given requirement, along with a typical output from the command to give you an idea of the kind of information you should see. Run each of these commands, (modified as appropriate for your environment) and copy the outputs into a document. Send this document to your Anaconda implementation team so that they can verify your environment is ready before you begin the installation process. * Verify that your [administration server](#administration-server) has been provisioned with appropriate versions of `kubectl`, `helm`, and other tools needed to perform installation and administration tasks by running the following command: ```sh theme={null} helm version ``` Here is an example response from the command: ```sh theme={null} version.BuildInfo{Version:"v3.7.1", GitCommit:"1d11fcb5d3f3bf00dbe6fe31b8412839a96b3dc4", GitTreeState:"clean", GoVersion:"go1.16.9"} ``` * Verify that the [API version](#supported-kubernetes-versions) of the Kubernetes cluster is between `1.15` and `1.28` by running the following command: ```sh theme={null} kubectl version ``` Here is an example response from the command: ``` Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.12", GitCommit:"e2a822d9f3c2fdb5c9bfbe64313cf9f657f0a725", GitTreeState:"clean", BuildDate:"2020-05-06T05:17:59Z", GoVersion:"go1.12.17", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.12", GitCommit:"e2a822d9f3c2fdb5c9bfbe64313cf9f657f0a725", GitTreeState:"clean", BuildDate:"2020-05-06T05:09:48Z", GoVersion:"go1.12.17", Compiler:"gc", Platform:"linux/amd64"} ``` * Verify all nodes nodes on which Workbench will be installed have [sufficient CPU and memory allocations](#cpu-memory-and-nodes) by running the following command: ```sh theme={null} kubectl get nodes -o=jsonpath="{range .items[*]}{.metadata.name}{'\t'}{.status.capacity.cpu}{'\t'}{.status.capacity.memory}{'\n'}{end}" ``` Here is an example response from the command: ``` 10.234.2.18 16 65806876Ki 10.234.2.19 16 65806876Ki 10.234.2.20 16 65806876Ki 10.234.2.21 16 65806876Ki 10.234.2.6 16 65974812Ki ``` * Verify that the [namespace](#namespace-service-account-rbac) where Workbench will be installed has been created by running the following command: ```sh theme={null} # Replace with the namespace you've reserved for Workbench kubectl describe namespace ``` Here is an example response from the command: ``` Name: default Labels: Annotations: Status: Active No resource quota. No resource limits. ``` * Verify the [service account](#namespace-service-account-rbac) that will be used by Workbench during installation and operation has been created by running the following command: ```sh theme={null} # Replace with the name of the service account you've created for Workbench kubectl describe sa ``` Here is an example response from the command: ``` Name: anaconda-enterprise Namespace: default Labels: Annotations: Image pull secrets: Mountable secrets: anaconda-enterprise-token-cdmnf Tokens: anaconda-enterprise-token-cdmnf Events: ``` * *(Openshift Only)* Verify the Security Context Constraint (SCC) associated with the service account contains all of the necessary permissions by running the following command: ```sh theme={null} oc describe scc ``` Here is an example response from the command: ``` Name: anyuid Priority: 10 Access: Users: Groups: system:cluster-admins ``` This example uses the `anyuid` SCC; however, the `restricted` SCC can also be used, as long as the `uid` range is known. * Verify the `ClusterRole` resource associated with the service account has the necessary permissions to facilitate installation and operation by running the following command: ```sh theme={null} # Replace with the name of the service account you've created for Workbench kubectl describe clusterrole -ingress ``` Here is an example response from the command: ``` Name: anaconda-enterprise-ingress Labels: app.kubernetes.io/managed-by=Helm skaffold.dev/run-id=8d38b94a-ab82-49d7-a6fd-0bc0fb549d1c Annotations: meta.helm.sh/release-name: anaconda-enterprise meta.helm.sh/release-namespace: default PolicyRule: Resources Non-Resource URLs Resource Names Verbs --------- ----------------- -------------- ----- *.* [] [] [*] [*] [] [*] ``` The above example is fully permissive. See the [RBAC template](#namespace-service-account-rbac) for more realistic configurations. * A numeric UID that will be used to run Workbench containers is reserved. Include the UID in your checklist results. * Verify that GID `0` is permitted by the security context. * Verify any [tolerations and/or node labels](#cpu-memory-and-nodes) required to permit Workbench to run on its assigned nodes have been identified by running the following command: ```sh theme={null} # This command returns information for tolerations only kubectl get nodes -o=jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.taints[*].key}{"\n"}{end}'`` ``` * Verify that a Persistent Volume Claim (PVC) has been created within the application namespace, referencing a statically provisioned Persistent Volume that meets the [storage requirements](#storage) for the `anaconda-storage` volume by running the following command: ```sh theme={null} kubectl describe pvc anaconda-storage ``` Here is an example response from the command: ``` Name: anaconda-storage Namespace: default StorageClass: anaconda-storage Status: Bound Volume: anaconda-storage Labels: Annotations: pv.kubernetes.io/bind-completed: yes pv.kubernetes.io/bound-by-controller: yes Finalizers: [kubernetes.io/pvc-protection] Capacity: 500Gi Access Modes: RWO VolumeMode: Filesystem Mounted By: anaconda-enterprise-ap-git-storage-6658575d6f-vxj4s anaconda-enterprise-ap-object-storage-76bcfc4d44-ctlhp anaconda-enterprise-postgres-c76869799-cbqzq Events: ``` * Verify a PVC has been created within the application namespace, referencing a statically provisioned Persistent Volume that meets the [storage requirements](#storage) for the `anaconda-persistence` volume by running the following command: ```sh theme={null} kubectl describe pvc anaconda-persistence ``` Here is an example response from the command: ``` Name: anaconda-persistence Labels: Annotations: pv.kubernetes.io/bound-by-controller: yes Finalizers: [kubernetes.io/pv-protection] StorageClass: Status: Bound Claim: default/anaconda-persistence Reclaim Policy: Retain Access Modes: RWX VolumeMode: Filesystem Capacity: 500Gi Node Affinity: Message: Source: Type: NFS (an NFS mount that lasts the lifetime of a pod) Server: 10.234.2.7 Path: /data/persistence ReadOnly: false Events: ``` * The cluster is sized appropriately (CPU / Memory) for user workload, including consideration for “burst” workloads. For more information, see [Understanding Workbench system requirements](/docs/data-science/5.8.1/reference/understanding-ae5). * [Resource Profiles](#resource-profiles) have been determined, and created in the `values.yaml` file. * A domain name for the Workbench application has been identified. Please include this domain name in your checklist output. * If you are supplying your own ingress controller, verify it has already been installed, and its master IP address and `ingressClassName` value have been identified. Please include both the IP address ingress class name in your checklist output. * Verify the DNS records for both `anaconda.example.com` and `*.anaconda.example.com` have been created and point to the IP address of the ingress controller by running the following command: ```sh theme={null} ping test.anaconda.example.com ``` Here is an example response from the command: ``` PING test.anaconda.example.com (167.172.143.144): 56 data bytes ``` If the ingress controller is to be installed with Workbench, this may not be possible. In such cases, it is sufficient to confirm that the networking team is prepared to establish these records immediately following installation. * A wildcard SSL secret for `anaconda.example.com` and `*.anaconda.example.com` has been created. The public and private keys for the main certificate, as well as the full public certificate chain, are accessible from the administration server. Please share the public certificate chain in your checklist output. * If the SSL secret was created using a private CA, verify the public root certificate has been obtained. * If you are using a private Docker registry, verify the full set of Docker images have been transferred to this registry. * If a [pull secret](https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/) is required to access the Docker images (whether from the standard Workbench Docker channel or the private registry) verify the secret has been created in the application namespace by running the following command: ```sh theme={null} # Replace with the namespace you've reserved for Workbench # Replace with the name for your pull secret kubectl get secret -n ```
