Question

我正在将Ansible与Docker一起部署ROR应用程序，创建了Ruby Docker映像并将其推送到Docker HUB，Ansible将应用程序从私有存储库克隆到目标服务器，成功创建了Docker容器，但无法运行诸如Bundle安装，DB Migrate，Rake Task之类的Ruby命令。这些命令需要在从Ansible Code以交互模式进行部署时运行。

以及如何使用独角兽运行上述任务后如何启动应用程序。

这是要使用Ansible（以前使用Capistrano，但现在我们要从Capistrano迁移到Ansible）来自动化部署过程。

我希望Ansible Playbook能够与Docker / Nginx / Unicorn一起部署Ruby on Rails应用程序

您的剧本失败了，因为您在docker_container模块（docker_container module

中指定了以下参数，该参数不是有效参数

...
bundler:
      deployment_mode: production

这里的另一种方法可能是这样

在/var/www/app-path/install-ror.sh

中创建Shell脚本

#!/bin/sh

working_dir=/var/www/app-path/
cd $working_dir

export gem_path=/var/www/app-path
export gemfile=/var/www/app-path

#see https://stackoverflow.com/questions/10912614/rails-bundle-install-production-only 
gem install bundle-only

#install only production modules
bundle-only production

如下更新您的剧本

- name: Run Ruby Docker Container
    docker_container:
        name: 'container_name'
        image: 'docker-hub/ruby-2.4.1:0.1'
        tty: yes
        detach: true
        restart: yes # not required. Use with started state to force a matching container to be stopped and restarted.
        interactive: yes # not required. Keep stdin open after a container is launched, even if not attached.
        state: started
        volumes: /var/www/app-path:/var/www/app-path/
        working_dir: /var/www/app-path/
        command: /var/www/app-path/install-ror.sh

您可以按照输出进行改进。
