Chapter 3. Install OpenDaylight on the overcloud

Red Hat OpenStack Platform director 10 provides an overcloud image that contains all of the necessary software for OpenStack services that run on overcloud nodes. However, the OpenDaylight software and dependencies are not included in the image by default. To install OpenDaylight, use the virt-customize command on the undercloud to upload the OpenDaylight RPM and install it:

Prepare the installation of OpenDaylight

  1. Log on to the undercloud node.

  2. Run the script: 

    $ source ~/stackrc

  3. Install the following packages: 

    $ sudo yum -y install libguestfs-tools libvirt rhosp-director-images

  4. Start the libvirtd service: 

    $ sudo systemctl start libvirtd

  5. Create the directory where you will store the images: 

    $ mkdir ~/images

  6. Enter the directory: 

    $ cd ~/images

  7. Extract the overcloud-full.tar file: 

    $ tar xvf /usr/share/rhosp-director-images/overcloud-full.tar

  8. Extract the ironic-python-agent.tar file: 

    $ tar xvf  /usr/share/rhosp-director-images/ironic-python-agent.tar

Install the OpenDaylight packages

  1. Register the image with your RHN user: 

    $ virt-customize -a overcloud-full.qcow2 --run-command 'subscription-manager register --username <your RHN user>  --password <RHN password>’

  2. Attach the Red Hat Enterprise Linux subscription: 

    $ virt-customize -a overcloud-full.qcow2 --run-command 'subscription-manager attach --pool <pool id>'

  3. Enable the necessary repositories in your image: 

    $ virt-customize -a overcloud-full.qcow2 --run-command 'subscription-manager repos --enable=rhel-7-server-rpms --enable=rhel-7-server-extras-rpms --enable=rhel-7-server-openstack-10-rpms'

  4. Install the OpenDaylight package and its dependencies: 

    $ virt-customize -a overcloud-full.qcow2 --install opendaylight --selinux-relabel --update

  5. Detach the subscription and unregister the image: 

    $ virt-customize -a overcloud-full.qcow2 --run-command 'subscription-manager remove --all && subscription-manager unregister && subscription-manager clean'

  6. If you do not have an overcloud image installed, skip this and proceed to next step. Otherwise update the image: 

    $ openstack overcloud image upload --update-existing --image-path ~/images/

  7. If you have skipped Step 6, upload the new overcloud image to glance: 

    $ openstack overcloud image upload
