Settings VirtualMachine. UpgradeVirtualHardware VirtualMachine. GuestControl VirtualMachine. PowerOff VirtualMachine. PowerOn VirtualMachine. Reset VirtualMachine. Create VirtualMachine. CreateFromExisting VirtualMachine. Delete VirtualMachine. Clone VirtualMachine. DeployTemplate VirtualMachine. MarkAsTemplate Folder.

Create Folder. Additionally, the user requires some ReadOnly permissions, and some of the roles require permission to propogate the permissions to child objects. These settings vary depending on whether or not you install the cluster into an existing folder. For more information about creating an account with only the required privileges, see vSphere Permissions and User Management Tasks in the vSphere documentation.

OpenShift Container Platform generally supports compute-only vMotion. Using Storage vMotion can cause issues and is not supported. If you are using vSphere volumes in your pods, migrating a VM across datastores either manually or through Storage vMotion causes invalid references within OpenShift Container Platform persistent volume PV objects.

These references prevent affected pods from starting up and can result in data loss. Similarly, OpenShift Container Platform does not support selective migration of VMDKs across datastores, using datastore clusters for VM provisioning or for dynamic or static provisioning of PVs, or using a datastore that is part of a datastore cluster for dynamic or static provisioning of PVs.

When you deploy an OpenShift Container Platform cluster that uses installer-provisioned infrastructure, the installation program must be able to create several resources in your vCenter instance. Although these resources use GB of storage, the bootstrap node is destroyed during the cluster installation process. A minimum of GB of storage is required to use a standard cluster.

If you deploy more compute machines, the OpenShift Container Platform cluster will use more storage. Available resources vary between clusters.

The number of possible clusters within a vCenter is limited primarily by available storage space and any limitations on the number of required resources. Be sure to consider both limitations to the vCenter resources that the cluster creates and the resources that you require to deploy a cluster, such as IP addresses and networks.

Additionally, you must create the following networking resources before you install the OpenShift Container Platform cluster:. Installation is possible without an NTP server. However, asynchronous server clocks will cause errors, which NTP server prevents. You must provide these IP addresses to the installation program when you install the OpenShift Container Platform cluster.

This record must be resolvable by both clients external to the cluster and from all the nodes within the cluster. If you want to SSH in to your cluster nodes to perform installation debugging or disaster recovery, you must provide the SSH public key during the installation process. Do not skip this procedure in production environments, where disaster recovery and debugging is required. You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

If you do not have an existing SSH key pair on your local machine to use for authentication onto your cluster nodes, create one. For example, on a computer that uses a Linux operating system, run the following command:. Instead, create a key that uses the rsa or ecdsa algorithm.

SSH agent management of the key is required for password-less SSH authentication onto your cluster nodes, or if you want to use the. If the ssh-agent process is not already running for your local user, start it as a background task:. Before you install OpenShift Container Platform, download the installation file on a local computer. If you have a Red Hat account, log in with your credentials. If you do not, create an account. Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.

The installation program creates several files on the computer that you use to install your cluster. You must keep the installation program and the files that the installation program creates after you finish installing the cluster.

Both files are required to delete the cluster. Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. To remove your cluster, complete the OpenShift Container Platform uninstallation procedures for your specific cloud provider. Extract the installation program. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay. Extract the compressed file that contains the vCenter root CA certificates.

The contents of the compressed file resemble the following file structure:. Add the files for your operating system to the system trust. For example, on a Fedora operating system, run the following command:. You can run the create cluster command of the installation program only once, during initial installation. Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Change to the directory that contains the installation program and initialize the cluster deployment:. Specify an empty directory. Some installation assets, like bootstrap X. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.

For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

Specify the user name and password for the vCenter account that has the required permissions to create the cluster. The installation program uses the root resource pool of the vSphere cluster as the default resource pool. Select the network in the vCenter instance that contains the virtual IP addresses and DNS records that you configured.

Enter the base domain. This base domain must be the same one that you used in the DNS records that you configured. Enter a descriptive name for your cluster.

The cluster name must be the same one that you used in the DNS records that you configured. If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed. If you have enough space on your system or C drive, then the wizard will enable the "Next" button to proceed with the upgrade.

Setup has already detected that we have another version installed so it is asking us to upgrade it. Click Next to go to next screen. Next the license agreement will appear. Click the checkbox to accept the licensing terms. Click Next to go further with the upgrade or installation.

The next page will let you choose the installation location. You can change the location as needed by using the "Change…" button. Click Next to continue. I chose the default location since I want to upgrade my existing installation.

This is the last window you will get as part of this installation or upgrade. Here you are upgrading an existing installation then you will get "Upgrade" button but if you are installing this software on new machine then you will get "Install" button. Once the upgrade or installation completes you will get the below window to either enter the License or Finish installation.

If you click Finish you can use the product, but will need to enter a license key at some point. Then click Finish to close the window. You will get a popup window to restart the computer to complete the remaining configurations. To configure your registry to use storage, change the spec. If the storage type is emptyDIR , the replica number cannot be greater than 1. You must configure storage for the Image Registry Operator. For non-production clusters, you can set the image registry to an empty directory.

If you do so, all images are lost if you restart the registry. If you run this command before the Image Registry Operator initializes its components, the oc patch command fails with the following error:.

To allow the image registry to use block storage types such as vSphere Virtual Machine Disk VMDK during upgrades as a cluster administrator, you can use the Recreate rollout strategy. Block storage volumes are supported but not recommended for use with image registry on production clusters.

An installation where the registry is configured on block storage is not highly available because the registry cannot have more than one replica. To set the image registry storage as a block storage type, patch the registry so that it uses the Recreate rollout strategy and runs with only 1 replica:. Create a pvc. For instructions about configuring registry storage so that it references the correct PVC, see Configuring the registry for vSphere.

After you complete the Operator configuration, you can finish installing the cluster on infrastructure that you provide. Alternatively, the following command notifies you when all of the clusters are available. It also retrieves and displays credentials:.

The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. View the logs for a pod that is listed in the output of the previous command by using the following command:.

Do not enable multipathing during installation. See "Enabling multipathing with kernel arguments on FCOS" in the Post-installation machine configuration tasks documentation for more information.

You can add extra compute machines after the cluster installation is completed by following Adding compute machines to vSphere. OKD provisions new volumes as independent persistent disks to freely attach and detach the volume on any node in the cluster. As a consequence, it is not possible to back up volumes that use snapshots, or to restore volumes from snapshots. See Snapshot Limitations for more information.

See About remote health monitoring for more information about the Telemetry service. Customize your cluster. If necessary, you can opt out of remote health reporting.

Set up your registry and configure registry storage. Optional: View the events from the vSphere Problem Detector Operator to determine if the cluster has permission or storage configuration issues. Installing a cluster on vSphere with user-provisioned infrastructure. Prerequisites You reviewed details about the OKD installation and update processes.

Be sure to also review this site list if you are configuring a proxy. VMware vSphere infrastructure requirements You must install the OKD cluster on a VMware vSphere version 6 or 7 instance that meets the requirements for the components that you use. Requirements for a cluster with user-provisioned infrastructure For a cluster that contains user-provisioned infrastructure, you must deploy all of the required machines.

This section describes the requirements for deploying OKD on user-provisioned infrastructure. Required machines The smallest OKD clusters require the following hosts:. All virtual machines must reside in the same datastore and in the same folder as the installer. Minimum resource requirements Each cluster machine must meet the following minimum requirements:.

Certificate signing requests management Because your cluster has limited access to automatic machine management when you use infrastructure that you provision, you must provide a mechanism for approving cluster certificate signing requests CSRs after installation. Networking requirements for user-provisioned infrastructure All the Fedora CoreOS FCOS machines require networking to be configured in initramfs during boot to fetch their Ignition config files.

Network connectivity requirements You must configure the network connectivity between machines to allow OKD cluster components to communicate. Host level services, including the node exporter on ports - Example DNS A record configuration for a user-provisioned cluster.

IN MX 10 smtp. IN A The record refers to the IP address of the API load balancer and is used for internal cluster communications. The record refers to the IP address of the application ingress load balancer.

IN PTR api. IN PTR api-int. IN PTR bootstrap. IN PTR master0. IN PTR master1. IN PTR master2. IN PTR worker0. IN PTR worker1. Load balancing requirements for user-provisioned infrastructure Before you install OKD, you must provision the API and application ingress load balancing infrastructure. The load balancing infrastructure must meet the following requirements:.

Configure the following conditions: Layer 4 load balancing only. Do not configure session persistence for an API load balancer. Configure the following ports on both the front and back of the load balancers:. Example load balancer configuration for user-provisioned clusters This section provides an example API and application ingress load balancer configuration that meets the load balancing requirements for user-provisioned clusters.

Preparing the user-provisioned infrastructure Before you install OKD on user-provisioned infrastructure, you must prepare the underlying infrastructure. The validation steps detailed in this section must succeed before you install your cluster. Agent pid Obtaining the installation program Before you install OKD, download the installation file on a local computer. Red Hat Operators are not available.

The Telemetry and Insights operators do not send data to Red Hat. Manually creating the installation configuration file For user-provisioned installations of OKD, you manually generate your installation configuration file. You must name this configuration file install-config. Sample install-config. All DNS records must be sub-domains of this base and include the cluster name. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, - , and the first line of the controlPlane section must not.

Although both sections currently define a single machine pool, it is possible that future versions of OKD will support defining multiple compute pools during installation. Only one control plane pool is used. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.

The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value. Preface a domain with. For example,. If you provide additionalTrustBundle and at least one proxy setting, the Proxy object is configured to reference the user-ca-bundle config map in the trustedCA field.

The installation program does not support the proxy readinessEndpoints field. Creating the Kubernetes manifest and Ignition config files Because you must modify some cluster definition files and manually start the cluster machines, you must generate the Kubernetes manifest and Ignition config files that the cluster needs to configure the machines.

Because you create and manage these resources yourself, you do not have to initialize them. Save and exit the file. Extracting the infrastructure name The Ignition config files contain a unique cluster identifier that you can use to uniquely identify your cluster in VMware vSphere.

Click the VMs and Templates view. Right-click the name of your datacenter. On the Select a compute resource tab, click the name of your vSphere cluster. On the Select storage tab, configure the storage options for your VM.

Select the datastore that you specified in your install-config. For a bootstrap machine, specify the URL of the bootstrap Ignition config file that you hosted. Navigate to a virtual machine from the vCenter Server inventory.

Optional: On the Select storage tab, customize the storage options. From the Latency Sensitivity list, select High. Define the following parameter names and values: guestinfo. Disk partitioning In most cases, data partitions are originally created by installing FCOS, rather than by installing another operating system.

SSH Public Key The root file system is automatically resized to fill all available space up to the specified offset. If no value is specified, or if the specified value is smaller than the recommended minimum, the resulting root file system will be too small, and future reinstalls of FCOS might overwrite the beginning of the data partition.

Updating the bootloader using bootupd To update the bootloader by using bootupd , you must either install bootupd on FCOS machines manually or provide a machine config with the enabled systemd unit.

After you have installed bootupd , you can manage it remotely from the OKD cluster. Inspect the system status: bootupctl status. Component EFI Installed: grub2-efi-x If the system status is Adoptable , perform the adoption:. Updated: grub2-efi-x Provide a machine config file with the enabled systemd unit, as shown in the following example: Example output.

To check your PATH , open the command prompt and execute the following command:. To check your PATH , open a terminal and execute the following command:. Waiting for the bootstrap process to complete The OKD bootstrap process begins after the cluster nodes first boot into the persistent FCOS environment that has been installed to disk.

INFO It is now safe to remove the bootstrap resources. Logging in to the cluster by using the CLI You can log in to your cluster as a default system user by exporting the cluster kubeconfig file. Approving the certificate signing requests for your machines When you add machines to a cluster, two pending certificate signing requests CSRs are generated for each machine that you added.

Some Operators might not become available until some CSRs are approved. Initial Operator configuration After the control plane initializes, you must immediately configure some Operators so that they all become available. Image registry removed during installation On platforms that do not provide shareable object storage, the OpenShift Image Registry Operator bootstraps itself as Removed. The Prometheus console provides an ImageRegistryRemoved alert, for example:. Image registry storage configuration The Image Registry Operator is not initially available for platforms that do not provide default storage.

Configuring registry storage for VMware vSphere As a cluster administrator, following installation you must configure your registry to use storage. When using shared storage, review your security settings to prevent outside access. Configuring storage for the image registry in non-production clusters You must configure storage for the Image Registry Operator. Configure this option for only non-production clusters.

Error from server NotFound : configs. Configuring block registry storage for VMware vSphere To allow the image registry to use block storage types such as vSphere Virtual Machine Disk VMDK during upgrades as a cluster administrator, you can use the Recreate rollout strategy. With ReadWriteOnce , the volume can be mounted with read and write permissions by a single node. Completing installation on user-provisioned infrastructure After you complete the Operator configuration, you can finish installing the cluster on infrastructure that you provide.

INFO Waiting up to 30m0s for the cluster to initialize If the pod logs display, the Kubernetes API server can communicate with the cluster machines. Backing up VMware vSphere volumes OKD provisions new volumes as independent persistent disks to freely attach and detach the volume on any node in the cluster. Stop the application that is using the persistent volume. Clone the persistent volume. Restart the application.

Create a backup of the cloned volume. Delete the cloned volume. Additional resources. Next steps Customize your cluster.

Storage with in-tree drivers. One temporary bootstrap machine. Three control plane machines. At least two compute machines, which are also known as worker machines.

The workloads requested by OKD users run on the compute machines. Network reachability tests. The default ports that Kubernetes reserves. Kubernetes node port. Kubernetes API. Bootstrap machine. Control plane machines. Compute machines. Provides name resolution for the Kubernetes API. Provides name resolution for the wildcard routes. Port handles the Kubernetes API traffic and points to the control plane machines. The bootstrap entries must be in place before the OKD cluster installation and they must be removed after the bootstrap process is complete.

Port handles the machine config server traffic and points to the control plane machines. The base domain of the cluster. The controlPlane section is a single mapping, but the compute section is a sequence of mappings. Whether to enable or disable simultaneous multithreading, or hyperthreading.
