Provisioning instances to a Red Hat OpenShift environment

Learn about the steps to provision a z/OS® instance that is running on an emulated IBM Z® hardware from a created image to a Red Hat® OpenShift® environment, or use a cloud-ready image to create an instance in the Red Hat OpenShift environment.

To provision instances from created images to a Red Hat OpenShift environment, complete the following steps:
  1. From the drop-down menu in the TARGET ENVIRONMENT pane, select a Red Hat OpenShift target environment to provision instances.
  2. Click Manage instances on the home page, or click the Instances tab on the header, and then click Provision instance.
  3. Enter a unique name that can be used to recognize the instance.
  4. Select an image that you want to provision in one of the following ways.
    • Select a created image by following these steps:
      1. Creating z/OS images or Creating ADCD images.
      2. If the image has multiple versions, then select a version.
      3. Enter the credentials that are used to log in to the final emulated IBM Z environment.
        • If you provision an instance from a z/OS image that requires the credentials, you must enter the initial password of the source environment. However, if you provision an instance from an ADCD image that requires the credentials, you can set the initial password for the user ID 'IBMUSER'. This password will be used when you log in to the final emulated z/OS system.
        • If you provision an instance from a cloud-ready image, this step is skipped.
    • Select a cloud-ready ready image by following the steps at Converting an image to a cloud-ready image.
  5. Configure the provisioning in one of the following ways.
    • Clear the Advanced settings option.
    • Enable the Advanced settings option. Then, complete the following optional steps:
      1. Define the central processors (CPs), integrated information processors (zIIPs), and available system memory size that are allocated to the emulator.
        • The total quantity of CPs and zIIPs cannot be more than 8, and the quantity of zIIPs cannot be greater than the quantity of CPs.
        • To ensure that the emulator performs well, the total quantity of CPs and zIIPs need to be less than the number of real cores on the target environment.
      2. Override the IPL command if you want. Specify the attributes of the device address, IODF volume device address, and LOADxx suffix.
      3. Specify the port of the service that is running on the z/OS that you want to expose. The SSH port name must be ssh, which is used to run all post-IPL tasks that need to connect to the target environment. If you use another SSH port number other than 22, set Expose SSH port (:22) to off, and then define your SSH port with a name that is exactly ssh in the Custom ports section.
  6. Click Provision instance to start the provisioning.
