8.4.22. コンピュートマシンの作成

手順

1. コマンドラインで、作業ディレクトリーを inventory.yaml および common.yaml ファイルの場所に変更します。

2. compute-nodes.yaml というローカルファイルに、以下のコンテンツを挿入します。

   例8.16 compute-nodes.yaml

   # Required Python packages:
   #
   # ansible
   # openstackclient
   # openstacksdk
   # netaddr
   
   - import_playbook: common.yaml
   
   - hosts: all
     gather_facts: no
   
     tasks:
     - name: 'Create the Compute ports'
       os_port:
         name: "{{ item.1 }}-{{ item.0 }}"
         network: "{{ os_network }}"
         security_groups:
         - "{{ os_sg_worker }}"
         allowed_address_pairs:
         - ip_address: "{{ os_subnet_range | next_nth_usable(7) }}"
       with_indexed_items: "{{ [os_port_worker] * os_compute_nodes_number }}"
       register: ports
   
     - name: 'Set Compute ports tag'
       command:
         cmd: "openstack port set --tag {{ cluster_id_tag }} {{ item.1 }}-{{ item.0 }}"
       with_indexed_items: "{{ [os_port_worker] * os_compute_nodes_number }}"
   
     - name: 'List the Compute Trunks'
       command:
         cmd: "openstack network trunk list"
       when: os_networking_type == "Kuryr"
       register: compute_trunks
   
     - name: 'Create the Compute trunks'
       command:
         cmd: "openstack network trunk create --parent-port {{ item.1.id }} {{ os_compute_trunk_name }}-{{ item.0 }}"
       with_indexed_items: "{{ ports.results }}"
       when:
       - os_networking_type == "Kuryr"
       - "os_compute_trunk_name|string not in compute_trunks.stdout"
   
     - name: 'Create the Compute servers'
       os_server:
         name: "{{ item.1 }}-{{ item.0 }}"
         image: "{{ os_image_rhcos }}"
         flavor: "{{ os_flavor_worker }}"
         auto_ip: no
         userdata: "{{ lookup('file', 'worker.ign') | string }}"
         nics:
         - port-name: "{{ os_port_worker }}-{{ item.0 }}"
       with_indexed_items: "{{ [os_compute_server_name] * os_compute_nodes_number }}"

3. コマンドラインで Playbook を実行します。

   $ ansible-playbook -i inventory.yaml compute-nodes.yaml
