elasticbeanstalkにcronoを設定したので、そのconfig

Elasticbeanstalk + rails + crono

railsでcron的なものを使いたかったけど、crontabを触りたくなかったので、cronoを使うことにした.その設定ファイル（結構作るのに時間かかったので。。。）
Cronoはこちら
I would like to use something like cron with rails, but didn't want to use crontab, so I try to use crono(I know it may not be maintained, but...), here is the config which I used.

環境

# rails -v
Rails 6.0.2.1
# uname -a
Linux ip-172-31-27-188 4.14.165-103.209.amzn1.x86_64 #1 SMP Sun Feb 9 00:23:26 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

設定ファイル

# cat .ebextensions/05_crono.config 
commands:
  create_post_dir:
    command: "mkdir -p /opt/elasticbeanstalk/hooks/appdeploy/post"
    ignoreErrors: true

files:
  "/opt/elasticbeanstalk/hooks/appdeploy/post/50_restart_crono.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      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_APP_LOG_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k app_log_dir)

      . $EB_SUPPORT_DIR/envvars
      . $EB_SCRIPT_DIR/use-app-ruby.sh
      PID=$EB_APP_PID_DIR/crono.pid
      cd $EB_APP_DEPLOY_DIR
      if [ -f $PID ] 
      then
        su -s /bin/bash -c "kill -TERM `cat $PID`" $EB_APP_USER
        su -s /bin/bash -c "rm -rf $PID" $EB_APP_USER
      fi
      . $EB_SUPPORT_DIR/envvars.d/sysenv
      sleep 10
      su -s /bin/bash -c "bundle exec crono start -P $PID " $EB_APP_USER
      sleep 10
      ln -sf $EB_APP_DEPLOY_DIR/log/crono.log $EB_APP_LOG_DIR
    "/opt/elasticbeanstalk/hooks/appdeploy/pre/03_mute_crono.sh":

        EB_SUPPORT_DIR=$(/opt/elasticbeanstalk/bin/get-config container -k support_dir)

        . $EB_SCRIPT_DIR/use-app-ruby.sh
        PID=$EB_APP_PID_DIR/crono.pid
        if [ -f $PID ] 
        then
          su -s /bin/bash -c "kill -USR1 `cat $PID`" $EB_APP_USER
        fi

テストに使ったjob

class CronoTestJob < ApplicationJob
  queue_as :default

  def logger
    Crono.logger.nil? ? Rails.logger : Crono.logger
  end

  def perform(*args)
    logger.info '*** start crono test job ***'
  end
end
