You can use basic Kubernetes YAML resource definitions to deploy Single-Node Single-Drive and Single-Node Multi-Drive topologies for local testing and evaluation as necessary. The Operator Console provides a rich user interface for deploying and managing MinIO Tenants on Kubernetes infrastructure. Installing the MinIO :ref:`Kubernetes Operator ` automatically installs and configures the Operator Console. This documentation assumes familiarity with all referenced Kubernetes concepts, utilities, and procedures. While this documentation *may* provide guidance for configuring or deploying Kubernetes-related resources on a best-effort basis, it is not a replacement for the official :kube-docs:`Kubernetes Documentation <>`. .. _deploy-minio-distributed-prereqs-storage: Prerequisites ------------- MinIO Kubernetes Operator and Plugin ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The procedures on this page *requires* a valid installation of the MinIO Kubernetes Operator and assumes the local host has a matching installation of the MinIO Kubernetes Operator. This procedure assumes the latest stable Operator and Plugin version |operator-version-stable|. See :ref:`deploy-operator-kubernetes` for complete documentation on deploying the MinIO Operator. .. cond:: k8s and not openshift .. include:: /includes/k8s/install-minio-kubectl-plugin.rst .. cond:: openshift .. include:: /includes/openshift/install-minio-kubectl-plugin.rst .. cond:: k8s and not openshift Kubernetes Version 1.19.0 ~~~~~~~~~~~~~~~~~~~~~~~~~ Starting with v4.0.0, the MinIO Operator requires Kubernetes 1.19.0 and later. The Kubernetes infrastructure *and* the ``kubectl`` CLI tool must have the same version of 1.19.0+. This procedure assumes the host machine has ``kubectl`` installed and configured with access to the target Kubernetes cluster. The host machine *must* have access to a web browser application. .. cond:: openshift OpenShift 4.7+ and ``oc`` CLI Tool ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This procedure assumes installation of the MinIO Operator using the OpenShift 4.7+ and the OpenShift OperatorHub. This procedure assumes your local machine has the OpenShift ``oc`` CLI tool installed and configured for access to the OpenShift Cluster. :openshift-docs:`Download and Install ` the OpenShift :abbr:`CLI (command-line interface)` ``oc`` for use in this procedure. See :ref:`deploy-operator-openshift` for more complete instructions. .. cond:: openshift Check Security Context Constraints ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The MinIO Operator deploys pods using the following default :kube-docs:`Security Context ` per pod: .. code-block:: yaml :class: copyable securityContext: runAsUser: 1000 runAsGroup: 1000 runAsNonRoot: true fsGroup: 1000 Certain OpenShift :openshift-docs:`Security Context Constraints ` limit the allowed UID or GID for a pod such that MinIO cannot deploy the Tenant successfully. Ensure that the Project in which the Operator deploys the Tenant has sufficient SCC settings that allow the default pod security context. You can alternatively modify the tenant security context settings during deployment. The following command returns the optimal value for the securityContext: .. code-block:: shell :class: copyable oc get namespace \ -o=jsonpath='{.metadata.annotations.openshift\.io/sa\.scc\.supplemental-groups}{"\n"}' The command returns output similar to the following: .. code-block:: shell 1056560000/10000 Take note of this value before the slash for use in this procedure. Persistent Volumes ~~~~~~~~~~~~~~~~~~ MinIO can use any Kubernetes :kube-docs:`Persistent Volume (PV) ` that supports the :kube-docs:`ReadWriteOnce ` access mode. MinIO's consistency guarantees require the exclusive storage access that ``ReadWriteOnce`` provides. For Kubernetes clusters where nodes have Direct Attached Storage, MinIO strongly recommends using the `DirectPV CSI driver `__. DirectPV provides a distributed persistent volume manager that can discover, format, mount, schedule, and monitor drives across Kubernetes nodes. DirectPV addresses the limitations of manually provisioning and monitoring :kube-docs:`local persistent volumes `. Deploy a Tenant using the MinIO Operator Console ------------------------------------------------ To deploy a tenant from the MinIO Operator Console, complete the following steps in order: :ref:`create-tenant-access-minio-operator-console` :ref:`create-tenant-complete-tenant-setup` :ref:`create-tenant-configure-section` :ref:`create-tenant-images-section` :ref:`create-tenant-pod-placement-section` :ref:`create-tenant-identity-provider-section` :ref:`create-tenant-security-section` :ref:`create-tenant-encryption-section` :ref:`create-tenant-deploy-view-tenant` :ref:`create-tenant-connect-tenant` :ref:`create-tenant-operator-forward-ports` .. _create-tenant-access-minio-operator-console: 1) Access the MinIO Operator Console ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. cond:: k8s and not openshift Use the :mc-cmd:`kubectl minio proxy` command to temporarily forward traffic between the local host machine and the MinIO Operator Console: .. code-block:: shell :class: copyable kubectl minio proxy .. cond:: openshift Use the :mc-cmd:`oc minio proxy ` command to temporarily forward traffic between the local host machine and the MinIO Operator Console: .. code-block:: shell :class: copyable oc minio proxy The command returns output similar to the following: .. code-block:: shell Starting port forward of the Console UI. To connect open a browser and go to http://localhost:9090 Current JWT to login: TOKEN Open your browser to the specified URL and enter the JWT Token into the login page. You should see the :guilabel:`Tenants` page: .. image:: /images/k8s/operator-dashboard.png :align: center :width: 70% :class: no-scaled-link :alt: MinIO Operator Console Click the :guilabel:`+ Create Tenant` to start creating a MinIO Tenant. .. _create-tenant-complete-tenant-setup: 2) Complete the Tenant :guilabel:`Setup` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The :guilabel:`Setup` pane displays core configuration settings for the MinIO Tenant. Settings marked with an asterisk :guilabel:`*` are *required*: .. list-table:: :header-rows: 1 :widths: 30 70 :width: 100% * - Field - Description * - :guilabel:`Name` - The name of the MinIO Tenant * - :guilabel:`Namespace` - The Kubernetes Namespace in which to deploy the tenant. You can create the namespace by selecting the plus :guilabel:`+` icon if it does not exist. The Operator supports at most *one* MinIO Tenant per namespace. * - :guilabel:`Storage Class` - Specify the Kubernetes Storage Class the Operator uses when generating Persistent Volume Claims for the Tenant. Ensure the specified storage class has sufficient available Persistent Volume resources to match each generated Persistent Volume Claim. * - :guilabel:`Number of Servers` - The total number of MinIO server pods to deploy in the Tenant. The Operator by default uses pod anti-affinity, such that the Kubernetes cluster *must* have at least one worker node per MinIO server pod. Use the :guilabel:`Pod Placement` pane to modify the pod scheduling settings for the Tenant. * - :guilabel:`Number of Drives per Server` - The number of storage volumes (Persistent Volume Claims) the Operator requests per Server. The Operator displays the :guilabel:`Total Volumes` under the :guilabel:`Resource Allocation` section. The Operator generates an equal number of PVC *plus two* for supporting Tenant services (Metrics and Log Search). The specified :guilabel:`Storage Class` *must* correspond to a set of Persistent Volumes sufficient in number to match each generated PVC. * - :guilabel:`Total Size` - The total raw storage size for the Tenant. Specify both the total storage size *and* the :guilabel:`Unit` of that storage. All storage units are in SI values, e.g. :math:`Gi = GiB = 1024^3` bytes. The Operator displays the :guilabel:`Drive Capacity` under the:guilabel:`Resource Allocation` section. The Operator sets this value as the requested storage capacity in each generated PVC. The specified :guilabel:`Storage Class` *must* correspond to a set of Persistent Volumes sufficient in capacity to match each generated PVC. * - :guilabel:`Memory per Node [Gi]` - Specify the total amount of memory (RAM) to allocate per MinIO server pod. See :ref:`minio-hardware-checklist-memory` for guidance on setting this value. The Kubernetes cluster *must* have worker nodes with sufficient free RAM to match the pod request. * - :guilabel:`Erasure Code Parity` - The Erasure Code Parity to set for the deployment. The Operator displays the selected parity and its effect on the deployment under the :guilabel:`Erasure Code Configuration` section. Erasure Code parity defines the overall resiliency and availability of data on the cluster. Higher parity values increase tolerance to drive or node failure at the cost of total storage. See :ref:`minio-erasure-coding` for more complete documentation. Select :guilabel:`Create` to create the Tenant using the current configuration. While all subsequent sections are *optional*, MinIO recommends reviewing them prior to deploying the Tenant. .. _create-tenant-configure-section: 3) The :guilabel:`Configure` Section ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The :guilabel:`Configure` section displays optional configuration settings for the MinIO Tenant and its supporting services. .. list-table:: :header-rows: 1 :widths: 30 70 :width: 100% * - Field - Description * - :guilabel:`Expose Services` - The MinIO Operator by default directs the MinIO Tenant services to request an externally accessible IP address from the Kubernetes cluster Load Balancer if one is available. Most public cloud Kubernetes infrastructures include a global Load Balancer which meets this requirements. Other Kubernetes distributions *may* include a load balancer that can respond to these requests. You can direct the Tenant to not make this request by toggling the option to :guilabel:`Off` for the MinIO Service and Console Service. * - :guilabel:`Override Tenant Defaults` - The MinIO Operator sets the Kubernetes Security Context for pods to a default of ``1000`` for User, Group, and FsGroup. The FSGroupChangePolicy defaults to ``Always``. MinIO does not run the pod using the ``root`` user. You can modify the Security Context to direct MinIO to run using a different User, Group,FsGroup ID, and FSGroupChangePolicy. You can also direct MinIO to run as the Root user. .. cond:: openshift .. important:: If your OpenShift cluster enforces :openshift-docs:`Security Context Constraints ` , ensure you set the Tenant constraints appropriately such that pods can start and run normally. * - :guilabel:`Override Log Search Defaults` - The MinIO Operator deploys a Log Search service (SQL Database and Log Search API) to support Audit Log search in the MinIO Tenant Console. You can modify the Security Context to run the associated pod commands using a different User, Group, or FsGroup ID. You can also direct the pod to not run commands as the Root user. You can also modify the storage class and requested capacity associated to the PVC generated to support the Log Search service. * - :guilabel:`Override Prometheus Search Defaults` - The MinIO Operator deploys a Prometheus service to support detailed metrics in the MinIO Tenant Console. You can modify the Security Context to run the associated pod commands using a different User, Group, or FsGroup ID. You can also direct the pod to not run commands as the Root user. You can also modify the storage class and requested capacity associated to the PVC generated to support the Prometheus service. .. _create-tenant-images-section: 1) The :guilabel:`Images` Section ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The :guilabel:`Images` section displays container image settings used by the MinIO Tenant. .. list-table:: :header-rows: 1 :widths: 30 70 :width: 100% * - Field - Description * - :guilabel:`MinIO's Image` - The container image to use for the MinIO Server. See the `MinIO Quay `__ or the `MinIO DockerHub `__ repositories for a list of valid tags. * - :guilabel:`Log Search API's Image` - The container image to use for MinIO Log Search API. * - :guilabel:`KES Image` - The container image to use for MinIO :minio-git:`KES `. * - | :guilabel:`Log Search Postgres Image` | :guilabel:`Log Search Postgres Init Image` - The container images to use for starting the PostgreSQL service supporting the Log Search API * - | :guilabel:`Prometheus Image` | :guilabel:`Prometheus Sidecar Image` | :guilabel:`Prometheus Init Image` - The container images to use for starting the Prometheus service supporting the Log Search API. .. _create-tenant-pod-placement-section: 5) The :guilabel:`Pod Placement` Section ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The :guilabel:`Pod Placement` section displays pod scheduler settings for the MinIO Tenant. .. list-table:: :header-rows: 1 :widths: 30 70 :width: 100% * - Field - Description * - :guilabel:`None` - Disables pod scheduling constraints for the tenant. This allows Kubernetes to schedule multiple Tenant pods onto the same node. This may decrease resiliency, as a single Kubernetes worker can host multiple MinIO pods. If that worker is down or lost, objects may also be unavailable or lost. Consider using this setting only in early development or sandbox environments with a limited number of worker nodes. * - :guilabel:`Default (Pod Anti-Affinity)` - Directs the Operator to set anti-affinity settings such that no Kubernetes worker can host more than one MinIO server pod for this Tenant. * - :guilabel:`Node Selector` - Directs the operator to set a Node Selector such that pods only deploy onto Kubernetes workers whose labels match the selector. .. _create-tenant-identity-provider-section: 6) The :guilabel:`Identity Provider` Section ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The :guilabel:`Identity Provider` section displays the :ref:`Identity Provider ` settings for the MinIO Tenant. This includes configuring an external IDP such as :ref:`OpenID ` or :ref:`Active Directory / LDAP `. .. list-table:: :header-rows: 1 :widths: 30 70 :width: 100% * - Field - Description * - :guilabel:`Built-In` - Configure additional internal MinIO users for the Operator to create as part of deploying the Tenant. * - :guilabel:`OpenID` - Configure an OpenID Connect-compatible service as an external Identity Provider (e.g. Keycloak, Okta, Google, Facebook, Dex) to manage MinIO users. * - :guilabel:`Active Directory` - Configure an Active Directory or OpenLDAP service as the external Identity Provider to manage MinIO users. .. _create-tenant-security-section: .. _minio-k8s-deploy-minio-tenant-security: 7) The :guilabel:`Security` Section ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The :guilabel:`Security` section displays TLS certificate settings for the MinIO Tenant. .. list-table:: :header-rows: 1 :widths: 30 70 :width: 100% * - Field - Description * - :guilabel:`Enable TLS` - Enable or disable TLS for the MinIO Tenant. * - :guilabel:`Enable AutoCert` - Directs the Operator to generate Certificate Signing Requests for submission to the Kubernetes TLS API. The MinIO Tenant uses the generated certificates for enabling and establishing TLS connections. * - :guilabel:`Custom Certificates` - Specify one or more custom TLS certificates for use by the MinIO Tenant. MinIO supports Server Name Indication (SNI) such that the Tenant can select the appropriate TLS certificate based on the request hostname and the certificate Subject Alternative Name. MinIO also supports specifying Certificate Authority certificates for validating client certificates minted by that CA. .. _create-tenant-encryption-section: 8) The :guilabel:`Encryption` Section ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The :guilabel:`Encryption` section displays the :ref:`Server-Side Encryption (SSE) ` settings for the MinIO Tenant. Enabling SSE also creates :minio-git:`MinIO Key Encryption Service ` pods in the Tenant to facilitate SSE operations. .. list-table:: :header-rows: 1 :widths: 30 70 :width: 100% * - Field - Description * - :guilabel:`Vault` - Configure `Hashicorp Vault `__ as the external KMS for storing root encryption keys. See :ref:`minio-sse-vault` for guidance on the displayed fields. * - :guilabel:`AWS` - Configure `AWS Secrets Manager `__ as the external KMS for storing root encryption keys.
