问题似乎是在 capistrano 部署期间，创建的 cron 作业具有RAILS_ENV=staging预期的效果，因为部署环境是staging. 但是，在 capistrano 回滚中，创建的 cron 作业具有正在回滚的 capistrano 阶段RAILS_ENV=new_staging。new_staging

我的日程文件

set :job_template, nil
job_type :rake,    "cd :path && :environment_variable=:environment bundle exec rake :task :output"

every 15.minute, roles: [:db] do
  rake "jobs:publish", output: lambda { "2>&1 >> /path/to/capistrano_directory/shared/log/jobs.log" }
end

我的 deploy/new_staging.rb 文件

set :branch, "develop"
set :deploy_env, 'staging'
set :rails_env, 'staging'

server "user@server_ip", :web, :app, :db, :metrics
role :db, "user@server_ip", :primary => true       # This is where Rails migrations will run
ssh_options[:forward_agent] = false                                # use local SSH keys remotely

ssh_options[:paranoid] = false

set :use_sudo, false
set :deploy_to, "/path/to/capistrano_directory"
set :unicorn_conf, "#{deploy_to}/current/config/environments/#{deploy_env}/unicorn.rb"
set :unicorn_pid, "#{deploy_to}/shared/pids/unicorn.pid"

before 'deploy:finalize_update', 'set_current_release'
before "deploy:finalize_update", "deploy:update_crontab"
after 'deploy:update_code', 'deploy:symlink_db'

namespace :deploy do
  task :symlink_db, :roles => :app do
    run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml"
  end

  task :start, :roles => :app, :except => { :no_release => true } do
    run "cd #{deploy_to}/current && bundle exec unicorn -c #{unicorn_conf} -E #{deploy_env} -D"
  end

  task :stop do
    run "#{try_sudo} kill -QUIT `cat #{unicorn_pid}`"
  end

  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} kill -s USR2 `cat #{unicorn_pid}`"
  end
end

task :set_current_release, :roles => :app, :except => { :no_release => true } do
  set :current_release, latest_release
end

还有我的 deploy.rb

require 'bundler/capistrano'
require 'capistrano/ext/multistage'
set :whenever_command, "bundle exec whenever"
set :whenever_environment, defer { stage }
set :whenever_roles, [:db, :metrics]
require "whenever/capistrano"

set :stages, %w(production staging new_staging)

set :application, "###"
set :repository,  "###"
set :deploy_via, :remote_cache
set :scm, :git

default_run_options[:shell] = '/bin/bash --login'

ssh_options[:forward_agent] = false
ssh_options[:paranoid] = false


namespace :deploy do
  desc "Update the crontab file"
  task :update_crontab do
    run "cd #{release_path} && RAILS_ENV=#{fetch(:rails_env)} bundle exec whenever --update-crontab #{application} --set environment=#{fetch(:rails_env)}"
  end
end
  • 每当版本（0.9.7）
  • Capistrano 版本 (2.12.0)

是什么导致回滚在运行时使用 capistrano 阶段而不是 rails_env gem？我怎样才能让它正确使用 rails_env？

我对您的 staging 设置感到有些困惑（staging 和 new_staging 有什么区别？）。也就是说，您应该能够通过更改您whenever_environment的使用rails_env而不是stagecapistrano 设置的值来做到这一点：

所以

set :whenever_environment, defer { stage }

会成为：

set :whenever_environment, defer { rails_env }

每当自述文件
