競技が開始したらやること

isucon-setupのansibleの実行​

ansible-playbook sites.yml -vv

失敗したら↓でやり直すと良い

ansible-playbook sites.yml -vv --start-at-task='<task名>'

特定のタスクをスキップしたいときはtagsをつけて --skip-tags すればよい

- name: want to skip
  ansible.builtin.shell:
    cmd: |
      ...
  tags:
    - onlyvm
ansible-playbook sites.yml -vv --start-at-task='<task名>' --skip-tags 'onlyvm'
