5 Installing the Command-Line Clients

During the installation, by default, the suite of OpenStack command-line tools are installed on the Cloud Lifecycle Manager and the control plane in your environment. This includes the OpenStack Command-Line Interface as well as the clients for the individual services such as the NovaClient, CinderClient, and SwiftClient. You can learn more about these in the OpenStack documentation here: OpenStack Command-Line Interface Reference.

If you wish to install the command-line interfaces on other nodes in your environment, there are two methods you can use to do so that we describe below.

5.1 Installing the CLI tools using the input model

During the initial install phase of your cloud you can edit your input model to request that the command-line clients be installed on any of the node clusters in your environment. To do so, follow these steps:

  1. Log in to the Cloud Lifecycle Manager.

  2. Edit your control_plane.yml file. Full path:

  3. In this file you will see a list of service-components to be installed on each of your clusters. These clusters will be divided per role, with your controller node cluster likely coming at the beginning. Here you will see a list of each of the clients that can be installed. These include:

  4. For each client you want to install, specify the name under the service-components section for the cluster you want to install it on.

    So, for example, if you would like to install the Nova and Neutron clients on your Compute node cluster, you can do so by adding the nova-client and neutron-client services, like this:

            - name: compute
              resource-prefix: comp
              server-role: COMPUTE-ROLE
              allocation-policy: any
              min-count: 0
                - ntp-client
                - nova-compute
                - nova-compute-kvm
                - neutron-l3-agent
                - neutron-metadata-agent
                - neutron-openvswitch-agent
                - neutron-lbaasv2-agent
                - nova-client
                - neutron-client

    This example uses the entry-scale-kvm sample file. Your model may be different so use this as a guide but do not copy and paste the contents of this example into your input model.

  5. Commit your configuration to the local git repo, as follows:

    cd ~/openstack/ardana/ansible
    git add -A
    git commit -m "My config or other commit message"
  6. Continue with the rest of your installation.

5.2 Installing the CLI tools using Ansible

At any point after your initial installation you can install the command-line clients on any of the nodes in your environment. To do so, follow these steps:

  1. Log in to the Cloud Lifecycle Manager.

  2. Obtain the hostname for the nodes you want to install the clients on by looking in your hosts file:

    cat /etc/hosts
  3. Install the clients using this playbook, specifying your hostnames using commas:

    cd ~/scratch/ansible/next/ardana/ansible
    ansible-playbook -i hosts/verb_hosts -e "install_package=<client_name>" client-deploy.yml -e "install_hosts=<hostname>"

    So, for example, if you would like to install the NovaClient on two of your Compute nodes with hostnames ardana-cp1-comp0001-mgmt and ardana-cp1-comp0002-mgmt you can use this syntax:

    cd ~/scratch/ansible/next/ardana/ansible
    ansible-playbook -i hosts/verb_hosts -e "install_package=novaclient" client-deploy.yml -e "install_hosts=ardana-cp1-comp0001-mgmt,ardana-cp1-comp0002-mgmt"
  4. Once the playbook completes successfully, you should be able to SSH to those nodes and, using the proper credentials, authenticate and use the command-line interfaces you have installed.
