![]() The unsung hero here are the hosting options available to us today. We were not confident that we’d be able to upgrade this server without extraordinary effort and significant downtime. Now that old server can be safely retired and removed from your deployment automation.ĭevelopment of this procedure was borne out of necessity for us. We will indeed clear all tasks managed by Whenever on both servers, but the tasks only get added back to the new server because of our clever configuration from before. Remember that our tasks are limited by the server’s role. The second is to actually write the crontab to both servers based on Whenever’s configuration.Ĭutover_tasks.sh: $ cap production whenever:clear_crontab The first step is to clear all cronjobs from both servers (the new server’s crontab is empty, and that’s okay). By configuring our new and old servers to exist in their own Capistrano roles in the deploy configuration we primed Whenever to perform the seamless cutover we required. With that option set, Whenever limits the servers on which it will define those tasks. This turned out to be a great thing because that meant we could expand Whenever’s set of roles without having those tasks defined on more servers. Our Whenever schedule has many more tasks than this, but they all define the roles option. This is what it looks like:ĭeploy.rb: server '0.0.0.0', roles: %w # New app server gets the existing roles After looking closely at this aspect of our configuration we realized that we could use Capistrano’s concept of servers fulfilling roles in an application to perform our cutover. We were also using its integration with our deployment automation tool Capistrano to limit background jobs to running only on our task server and not the web servers. Whenever provides a Ruby API to describe cron jobs, then converts them to cron syntax and inserts the rules into the server’s crontab. We use the Whenever Ruby gem to manage scheduling of background tasks. What we found was that our existing task scheduling and deployment automation were flexible enough to fulfill these requirements. Only then could we delete the old instance. Instead, we needed to simultaneously start running tasks on a new server while stopping them on the existing one. However, a dedicated task server on the project couldn’t simply be taken offline, nor could we risk running two of them with different Ruby versions. Servers meant to service web requests were easy remove them from the load balancer and shut them down.
