Question

我意识到有一些关于此的文章，但我正在尝试在Elastic Beanstalk上部署Rails应用程序并在部署过程中启动delayed_job，但我还没有设法让它工作。

我已尝试在.ebextensions文件夹中设置配置文件：

命令：创造 - -DIR后：命令：“mkdir / opt / elasticbeanstalk / hooks / appdeploy / post” ignoreErrors：true

文件： “/opt/elasticbeanstalk/hooks/appdeploy/post/restart_delayed_job.sh”：模式：“000755” 所有者：root group：root 内容：| ＃！/ usr / bin / env bash

  # Loading environment data
  EB_APP_USER=$(/opt/elasticbeanstalk/bin/get-config container -k app_user)
  EB_APP_DEPLOY_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k app_deploy_dir)
  EB_APP_PID_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k app_pid_dir)
  EB_SCRIPT_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k script_dir)
  EB_SUPPORT_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k support_dir)
  # Export EB_APP_LOG_DIR so we can access it when running bin/delayed_job below,
  # which accesses config/initializers/delayed_job.rb, which uses EB_APP_LOG_DIR.
  export EB_APP_LOG_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k app_log_dir)

  # Make sure the delayed_job.log exists and is owned by $EB_APP_USER
  touch $EB_APP_LOG_DIR/delayed_job.log
  chown $EB_APP_USER:$EB_APP_USER $EB_APP_LOG_DIR/delayed_job.log

  # Setting up correct environment and ruby version so that bundle can load all gems
  . $EB_SUPPORT_DIR/envvars
  . $EB_SCRIPT_DIR/use-app-ruby.sh

  # Now we can do the actual restart of the worker. Make sure to have double quotes when using env vars in the command.
  # For Rails 4, replace script/delayed_job with bin/delayed_job
  cd $EB_APP_DEPLOY_DIR
  su -s /bin/bash -c "bundle exec bin/delayed_job --pid-dir=$EB_APP_PID_DIR restart" $EB_APP_USER
  su -s /bin/bash -c "bundle exec bin/delayed_job --pid-dir=$EB_APP_PID_DIR status" $EB_APP_USER

非常感谢任何帮助我们开展此工作！

在花了很多时间之后，我终于得到了以下的工作。虽然它不适用于delayed_job，但我相信这解决了获取rails环境设置以便捆绑运行的相同问题。

<强> .ebextensions / 01_my_server.config

files:
"/opt/elasticbeanstalk/hooks/appdeploy/post/99_restart_my_servers.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
        #!/usr/bin/env bash
        EB_APP_USER=$(/opt/elasticbeanstalk/bin/get-config container -k app_user)
        EB_APP_DEPLOY_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k app_deploy_dir)
        EB_APP_PID_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k app_pid_dir)
        EB_SCRIPT_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k script_dir)
        EB_SUPPORT_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k support_dir)

        . $EB_SUPPORT_DIR/envvars
        . $EB_SCRIPT_DIR/use-app-ruby.sh

        mkdir -p /home/webapp
        chown webapp:webapp /home/webapp
        mkdir -p /home/webapp/pids
        chown webapp:webapp /home/webapp/pids

        cd $EB_APP_DEPLOY_DIR
        su -m -c "bundle exec bin/my_server.rb --pid-dir=/home/webapp/pids restart" -s /bin/bash webapp

注意事项：

使用su -m选项来保持环境变量。
使用su -s选项为webapp用户指定shell。
守护进程pid需要存储在/ var / app / current之外，因为每次新部署都会删除它（因此会中断重启守护进程）

部署Rails应用程序，并将delayed_job作为守护程序任务运行
