The issue seems to be that during a capistrano deploy the created cron job has RAILS_ENV=staging as expected since the deployment environment is staging. However, in a capistrano rollback the created cron job has RAILS_ENV=new_staging where new_staging is the capistrano stage being rolled back.
my schedule file
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
My deploy/new_staging.rb file
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
And my 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
What is causing the rollback to use the capistrano stage instead of the rails_env when running Whenever gem? And how can I get it to properly use the rails_env?
I'm a little confused by your staging setup (what is the difference between staging and new_staging?). That said, you should be able to do this by changing your whenever_environment to use rails_env instead of the stage value set by capistrano:
so
set :whenever_environment, defer { stage }
Would become:
set :whenever_environment, defer { rails_env }
