Lifecycle for guest operating systems 

In the lifecycle of an operating system, end of support (EOS) is the last date that IBM Cloud® delivers standard support for a version or release of a product. The end of support date is aligned to the vendor and community support dates. A notification is sent out 90 days before support for an operating system is withdrawn.



Table 1. Image lifecycle status

 Image status Description 

 available The most current version of the stock operating system image is available. When a new version of an operating system is made available, the older version image of that guest operating system changes to deprecated. No stock operating system that reaches EOS has an available image. 
 deprecated Older versions of stock operating systems are deprecated. Also, any stock operating system that reached EOS is also deprecated. The UI doesn't display any deprecated images when creating an instance. These images are still visible in the CLI and API. 



If you choose to continue to use a deprecated stock operating system image after EOS, be aware of the following risks:



* The operating system no longer receives security patches or updates.
* The operating system is no longer tested for hardware, drivers, or firmware.
* There is no support for performance or operational issues on the server.
* There is no vendor support for the operating system.
* EOS operating systems are not supported by IBM Cloud Technical Support.

VPC Instance Metadata Service (GA)
: The VPC Instance Metadata service is now generally available in all regions. This free service provides a REST API that you invoke within an instance to get information about that instance. Access to the API is unavailable from outside the instance. The service is disabled by default. Before you can access the metadata, you need to use the service to generate an instance identity access token for accessing the metadata service. You can optionally get an IAM token from this token to access all IAM-enabled services.

Changes with Citrix XenServer 6.2 and greater 

The release of Citrix XenServer 6.2+ brings several changes that not only impact how XenServer functions but how the product is offered.

XenServer 6.2+ Free is now an option, but it is unlicensed. After a device is provisioned with XenServer Free, it can be upgraded to the licensed version at any time. If you want to upgrade to XenServer Paid, the license is available for direct purchase from [Citrix ![External link icon](https://cloud.ibm.com/docs-content/v1/content/icons/launch-glyph.svg)](https://www.citrix.com/products/xenserver/buy.html). Licensing is acquired on a per-socket basis.

Note: Upgrading to XenServer Paid can still be initiated from within the XenServer application. Go to Tools > License Manager to view each Pool or Host that is associated with the account. Click Buy Licenses to be directed to the XenServer site to purchase licenses.

For more information about XenServer 6.2+, see the [XenServer ![External link icon](https://cloud.ibm.com/docs-content/v1/content/icons/launch-glyph.svg)](https://www.citrix.com/products/xenserver/overview.html) home page.
: Optional: Download the Calico configuration file, TLS certificates, and permission files that are required to run calicoctl commands in your cluster. This option can't be used with the --yaml option.

--skip-rbac
: Skip adding user Kubernetes RBAC roles based on the IBM Cloud IAM service access roles to the cluster configuration. Include this option only if you [manage your own Kubernetes RBAC roles](https://cloud.ibm.com/docs/containers?topic=containers-usersrbac). If you use [IBM Cloud IAM service access roles](https://cloud.ibm.com/docs/containers?topic=containers-iam-service-access-roles) to manage all your RBAC users, don't include this option.

-q
: Optional: Do not show the message of the day or update reminders.

--yaml
: Optional: Prints the command output in YAML format.



 Example cluster config command 

ibmcloud ks cluster config --cluster my_cluster







 ibmcloud ks cluster create classic 

Classic infrastructure

Create a cluster with worker nodes on classic infrastructure. For free clusters, you specify the cluster name; everything else is set to a default value. A free cluster is automatically deleted after 30 days. You can have one free cluster at a time. To take advantage of the full capabilities of Kubernetes, create a standard cluster.
Build a network 

IBM® Blockchain Platform is a blockchain-as-a-service offering that enables you to develop, deploy, and operate blockchain applications and networks. You can learn more about blockchain components and how they work together by visiting the [Blockchain component overview](https://cloud.ibm.com/docs/blockchain?topic=blockchain-blockchain-component-overviewblockchain-component-overview). This tutorial is the first part in the [sample network tutorial series](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-console-build-networkibp-console-build-network-sample-tutorial) and describes how to use the IBM Blockchain Platform console to build a fully functional network on Kubernetes cluster deployed into the cloud infrastructure of your choice.

Target audience: This topic is designed for network operators who are responsible for creating, monitoring, and managing the blockchain network.

If you have not already used the IBM Blockchain Platform console to deploy components to a Kubernetes cluster on IBM Cloud, see [Getting started with IBM Blockchain Platform for IBM Cloud](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-v2-deploy-iksibp-v2-deploy-iks). Note that the console itself does not reside in your cluster. It is a tool that you can use to deploy components into your cluster.

Whether you deploy components to a paid or free Kubernetes cluster, pay close attention to the amount of available resources in your cluster when you choose to deploy nodes and create

channels. It is your responsibility to manage your Kubernetes cluster and deploy additional resources when necessary. While components will successfully deploy to an IBM Cloud free cluster, the more components you add, the slower your components will run.

* CLI
* API







 Creating dedicated hosts and groups 

You can create one or more dedicated hosts with associated dedicated host groups in your IBM Cloud® VPC by using the IBM Cloud console, the CLI, or the API. Dedicated Host for VPC is fully integrated into IBM Cloud.

Dedicated hosts are not supported for LinuxONE (s390x processor architecture).



 Dedicated hosts 

You can create a dedicated host to carve out a single-tenant compute node, free from users outside of your organization. Within that dedicated space, you can create virtual server instances according to your needs. Additionally, you can create dedicated host groups that contain dedicated hosts for a specific purpose. Because a dedicated host is a single-tenant space, only users within your account that have the required permissions can create instances on the host.

When you create a dedicated host, you are billed by the usage of the host on an hourly basis. You are not billed for the vCPU and RAM associated with instances that are running on the host.

When you provision a dedicated host, the host is owned and managed by IBM. For more information about your responsibilities for managing virtual server instances provisioned on the host, see [Understanding your responsibilities when using Virtual Private Cloud](https://cloud.ibm.com/docs/vpc?topic=vpc-responsibilities-vpc).

To create a dedicated host and associated dedicated host group you must have a minimum role of Editor assigned in IBM Cloud Identity and Access Management (IAM) access policies. Within VPC Infrastructure Services access, Dedicated Host for VPC access is given as a set of permissions, including access to dedicated hosts, dedicated host groups, and to provision instances on dedicated hosts. If you want to assign granular access for users to a specific resource, such as a dedicated host group, you can create a separate [resource group](https://cloud.ibm.com/docs/account?topic=account-rgs) for that resource with a separate access policy and minimum access role assigned.
You can preview the IBM Blockchain Platform at no charge for 30 days when you link your IBM Blockchain Platform service instance to an IBM Cloud Kubernetes free cluster.

Limitations of the free preview



* Performance will be limited by throughput, storage, and functionality. Read more about the [limitations of free clusters](https://cloud.ibm.com/docs/containers?topic=containers-cs_ovcluster_types).
* IBM Cloud will delete your Kubernetes cluster after 30 days.
* Only one blockchain console can be connected to a free cluster at a time.
* You cannot migrate any nodes or data from a free cluster to a paid cluster.



The following capabilities are only available on a paid cluster:



* Customizing resource allocation for a node during or after deployment.
* Using a Hardware Security Module (HSM) to secure the private key for a node.
* Configuring a Certificate Authority (CA) for high availability by using a PostgreSQL database and replica sets.
* Selecting a specific Kubernetes zone when deploying a node.
* Overriding node configuration during or after deployment by using the console or APIs.
* Adding or removing ordering nodes to an ordering service. The free offering only supports a single node Raft ordering service.



How to preview IBM Blockchain Platform for free



1. Get an [IBM Cloud Account](https://cloud.ibm.com/registration?target=%2Fcatalog%2Fservices%2Fblockchain).
2. Upgrade your IBM Cloud Account to "Pay-as-you-go" by adding in a credit card. You will not be charged.
3. Launch IBM Blockchain Platform in the [IBM Cloud Catalog](https://cloud.ibm.com/catalog/services/blockchain-platform).
4. Under Select a pricing plan, ensure that the Standard plan is selected and then click Create.
5. On the Welcome and pre-requisites panel that opens, click I have a Cluster (Skip to Link a cluster).
6.
If you have not already used the IBM Blockchain Platform console to deploy components to a Kubernetes cluster on IBM Cloud, see [Getting started with IBM Blockchain Platform for IBM Cloud](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-v2-deploy-iksibp-v2-deploy-iks). Note that the console itself does not reside in your cluster. It is a tool that you can use to deploy components into your cluster.

Whether you deploy components to a paid or free Kubernetes cluster, pay close attention to the resources at your disposal when you choose to deploy nodes and create channels. It is your responsibility to manage your Kubernetes cluster and deploy additional resources if necessary. While components will successfully deploy to an IBM Cloud free cluster, the more components you add, the slower your components will run. For more information about component sizings and how the console interacts with your Kubernetes cluster on IBM Cloud, see [Allocating resources](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-console-adv-deploymentibp-console-adv-deployment-allocate-resources).



 Sample network tutorial series 

You are currently on the second part of our three-part tutorial series. This tutorial guides you through the process of using the console to create and join a peer node to an existing IBM Blockchain Platform network. Note that while this tutorial shows how this process works with a paid Kubernetes cluster on IBM Cloud, the same basic flow applies to free clusters, albeit with a few limitations (for example, you cannot size or resize nodes in a free cluster).



* [Build a network tutorial](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-console-build-networkibp-console-build-network) guides you through the process of hosting a network by creating an ordering service and a peer.
* Join a network tutorial (Current tutorial) Guides you through the process of joining an existing network by creating a peer and joining it to a channel.
Acquisition and activation of the license is between you and the OS vendor. BYOL is not supported on Red Hat Enterprise Linux for SAP.
