Provisioning instances to a Docker environment

Edit online

Learn about the steps to provision instances from an image to a Docker environment, or resume a failed provisioning.

To provision instances from an image to a Docker environment, complete the following steps:
  1. From the drop-down menu in the TARGET ENVIRONMENT pane, select a Docker environment to provision instances.
  2. Click Manage instances on the home page. Or, click the Instances tab on the header, and click Provision instance.
  3. Enter a unique name that can be used to recognize your instance.
  4. Select an image and the version you want to provision to the container.
  5. Optional: Enter some notes that can help you identify the instance.
  6. If you provision an instance from an image that contains data set components. Enter the credentials to access the source environment.

    The credentials are needed to restore data sets in a more flexible and efficient way. The ZD&T Enterprise Edition needs to log in to the source environment to run the job or program.

    Note: 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.
  7. Configure the provisioning in one of the following ways.
    • Clear the Advanced settings option, and click Provision instance to start the provisioning.
    • Enable the Advanced settings option. Then, complete the following optional steps:
      1. Configure the central processors (CPs), integrated information processors (zIIPs), and available system memory size that are allocated to the instance.
        Notes:
        • 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 should 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 address, and LOADxx suffix.
      3. Specify the private port of your Docker environment.
  8. Click Provision instance.
