Extending an existing OpenStack engine#

To connect the blueprint design server to an OpenStack-based cloud, extend the Heat orchestration engine that is associated with the cloud. By extending the engine, you add custom types to it so that you can use it with the blueprint design server.

Before you install the engine, ensure that you do the following steps:

  1. Root access is required for installation.
  2. The operating system must be configured with required packages and dependencies before you install the engine. The system might need network access to install these packages. Make sure that the system is connected to a package manager, such as a Yum server.
  3. Enable the optional "rhel-7-server-optional-rpms" repository.

    • On RHEL systems that use the Red Hat Network subscription-based package manager, use the following command:

      subscription-manager repos --enable=rhel-7-server-optional-rpms

    • On virtual machines that are hosted on Amazon Web Services, run the following command:

      yum-config-manager --enable rhui-REGION-rhel-server-optional

  4. Determine whether the akonadi package is installed on the system.

    rpm -ql akonadi

  5. If the akonadi package is installed, remove it:

    yum remove -y akonadi

  6. Determine whether the program qpid is installed on the system.

    • On RHEL version 7, run the following command:

      systemctl status qpidd.service

  7. If the program qpid is running on the system, stop its service.

    • On RHEL version 7, run the following command:

      systemctl stop qpidd.service

To deploy environments to OpenStack clouds and clouds that are based on OpenStack, you install the blueprint design server and extend the Heat engine that is associated to the cloud. In this case, you do not use the Heat engine that comes with UrbanCode Deploy.

To extend a Heat orchestration engines for the blueprint design server, do the following steps:

  1. Download and extract the installation files for the engine.

    These files are available for download from the HCL® Passport Advantage® website. See the HCL UrbanCode Deploy download document.

  2. Change to the ibm-ucd-patterns-install/engine-install/ directory.

  3. From the command line, run the ./extend-ucd-existing-engine.sh command to install the UrbanCode Deploy plug-in.

  4. The installer asks if you have satisfied the dependencies. If you configured the system with the prerequisites for the engine, press Y.

  5. Read the license agreements for the software package. Press Space to show one page at a time, or press F to show the entire license.

  6. If you agree to the terms of all of the license agreements, press Y, and then press Enter.

  7. If you use a Kilo-level Heat engine and apply Chef roles to environments, modify the engine to be compatible with Chef.

    Run the following commands:

    sed -i '125,127 s/^/#/' /usr/lib/python2.7/site-packages/heat/engine/resources/openstack/heat/software_deployment.py sed -n '125,127p' /usr/lib/python2.7/site-packages/heat/engine/resources/openstack/heat/software_deployment.py

    The following text is displayed in the command line:



    constraints.CustomConstraint('nova.server')# ]


  8. Restart the engine and the Heat API.

    See the documentation for your cloud system.

  9. Verify that the new resource types are available in the engine by running the following command:

    heat resource-type-list

    If you see resource types that start with HCL::UrbanCode, such as HCL::UrbanCode::SoftwareDeploy::UCD, you correctly added the required types to the engine.

The engine is configured to work with the blueprint design server.
