8.3.17. Creating the bootstrap machine

Create a bootstrap machine and give it the network access it needs to run on Red Hat OpenStack Platform (RHOSP). Red Hat provides an Ansible playbook that you run to simplify this process.

Prerequisites

  • The inventory.yaml and common.yaml Ansible playbooks in a common directory

    • If you need these files, copy them from Creating network resources
  • The metadata.json file that the installation program created is in the same directory as the Ansible playbooks

Procedure

  1. On a command line, change the working directory to the location of the inventory.yaml and common.yaml files.
  2. Insert the following content into a local file that is called bootstrap.yaml:

    例8.5 bootstrap.yaml

    # Required Python packages:
    #
    # ansible
    # openstackclient
    # openstacksdk
    # netaddr
    
    - import_playbook: common.yaml
    
    - hosts: all
      gather_facts: no
    
      tasks:
      - name: 'Create the bootstrap server port'
        os_port:
          name: "{{ os_port_bootstrap }}"
          network: "{{ os_network }}"
          security_groups:
          - "{{ os_sg_master }}"
          allowed_address_pairs:
          - ip_address: "{{ os_subnet_range | next_nth_usable(5) }}"
          - ip_address: "{{ os_subnet_range | next_nth_usable(6) }}"
    
      - name: 'Set bootstrap port tag'
        command:
          cmd: "openstack port set --tag {{ cluster_id_tag }} {{ os_port_bootstrap }}"
    
      - name: 'Create the bootstrap server'
        os_server:
          name: "{{ os_bootstrap_server_name }}"
          image: "{{ os_image_rhcos }}"
          flavor: "{{ os_flavor_master }}"
          userdata: "{{ lookup('file', os_bootstrap_ignition) | string }}"
          auto_ip: no
          nics:
          - port-name: "{{ os_port_bootstrap }}"
    
      - name: 'Create the bootstrap floating IP'
        os_floating_ip:
          state: present
          network: "{{ os_external_network }}"
          server: "{{ os_bootstrap_server_name }}"
  3. On a command line, run the playbook:

    $ ansible-playbook -i inventory.yaml bootstrap.yaml
  4. After the bootstrap server is active, view the logs to verify that the Ignition files were received:

    $ openstack console log show "$INFRA_ID-bootstrap"
