Ansible 显示 rails 测试的输出

Question

我有以下ansible play:

- name: run rails tests
  hosts: marflar
  sudo: yes
  sudo_user: vagrant
  tags:
    - rake
  tasks:
    - name: configure nokogiri
      command: bash -lc "bundle config build.nokogiri --use-system-libraries"

    - name: install gems
      command: bash -lc "bundle install"
      register: bundle_complete

    - name: check if database exists
      command: bash -lc "bundle exec rake db:version"
      ignore_errors: True
      register: rake_db_version_result

    - name: create database
      command: bash -lc "bundle exec rake db:setup"
      register: db_setup_complete
      when: rake_db_version_result|failed

    - name: apply database migrations
      command: bash -lc "bundle exec rake db:migrate"
      register: db_setup_complete
      when: rake_db_version_result|success

    - name: running the test suite
      command: bash -lc "bundle exec rake test"
      when: db_setup_complete

它运行良好，但在它完成之前我看不到 bundle exec rake test 的输出。有没有办法显示我的测试输出？

看起来像lot of people have requested this feature, but that the Ansible maintainers have decided that this kind of feature is not a good fit for the way Ansible is built。

为清晰起见编辑：

不支持在ansible中提供实时输出的原因有很多，工单中有一些可靠的论据：

Ansible contains 235+ modules and the APIs used in basically all of these modules don't have any capacity for reporting status in the middle of an async operation

和

The CLI has no good way to output standard out changes when running in parallel against several hundred hosts

如果你真的想在命令执行时看到它的输出，你最好尝试 ssh 或其他一些工具，Ansible 不能这样做。
