我正在使用 Ansible 和 Docker 部署 ROR 应用程序，创建 Ruby Docker 映像并推送到 Docker HUB，Ansible 将应用程序从私有仓库克隆到目标服务器，成功创建了 docker 容器，但无法运行 Ruby 命令，例如捆绑安装、数据库迁移、Rake 任务。这些命令需要在从 Ansible Code 以交互模式部署时运行。

以及如何在使用 unicorn 运行上述任务后启动应用程序。

这是为了使用 Ansible 自动化部署过程，以前使用 Capistrano，但现在我们正在从 Capistrano 迁移到 Ansible。

我希望 Ansible Playbook 使用 Docker / Nginx / Unicorn 部署 Ruby on Rails 应用程序

您的剧本失败了，因为您指定了以下参数，该参数不是 docker_container 模块（docker_container 模块

...
bundler:
      deployment_mode: production

这里的另一种方法可能是这样的

在 /var/www/app-path/install-ror.sh 中创建一个 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

您可以按照输出来改进这一点。
