When a family tries to sweep tragedy under the rug, the damage is deep and lasting.

If you've ever worked with Capistrano or Envoyer, you've probably seen a directory structure in your webroot that looks something like this: root root 4096 Mar 29 18:44 . root root 4096 Mar 28 14:15 .. root root 47 Mar 29 14:54 current -> ./releases/1490824249 root root 4096 Mar 29 14:50 releases Where you're expecting to see your webroot containing your Git repository, instead it's this weird structure. What gives? A brief introduction to Capistrano-style zero-downtime deploys The reason you're getting zero-downtime deploy from these tools is because the entire deploy process—clone, composer install, etc.—doesn't happen in the directory that is currently serving your site. Instead, each new release gets its own separate "release" directory, all while your site is still being served from its current "release" directory. - current -> ./releases/1490802721 * apache/nginx serves from this directory - releases - 1490802133 (the new release you're building right now) - 1490802721 (latest complete release) - 1490803081 (a little bit older release) - 1490824249 (an even older release) All of these release directories are just subdirectories of releases. Each directory here represents one of your deploys, and each directory individually has everything needed to serve your site. Your web server points to yourproject/current/public and therefore the "currently served" release is just that which has a symlink pointed at it from yourproject/current. So, once the build process is complete for each new release, your deploy tool will delete the current symlink and create a new current symlink that points to your latest release. Boom. Now that release is live. Caveats In general, Laravel is no different from any other project in that this style of deployment works great. In fact, a tool provided by Taylor Otwell, Envoyer, is predicated around this release style. However, every tool has a different set of caveats around how to handle them well in zero-downtime settings. Here's why: There are always some things that you want to persist between releases. Most of it lives in databases and caches, which is fine—nothing's wiping your database on every deploy. But some isn't. Take the storage folder; do you want to wipe that every time you push a new release? Naw. What about the .env file? Definitely naw. So there are a few quick tricks. How to set up your deploy for Laravel Remember: If you use Envoyer, this is all handled for you. But if you don't, here's what to do. Clone your release into a new release folder. This should be handled by your deploy tool. composer install -o --no-interaction php artisan migrate --no-interaction --force (optional, if you don't commit your built scripts) npm install (or yarn) and either gulp --production (Elixir) or npm run production (Mix) rm -rf storage && ln -s ../../storage ./ (Delete the storage directory and symlink it to a storage folder in the parent) ln -s ../../.e

Everyone I know seems a little ashamed of the compulsive phone-checking, but it is, circa 2017, our species-specific calling card, as surely as the bobbing head-thrust identifies the pigeon. No one much likes spending half the workday on e-mail, but that’s what work is for many of us. Our accelerating disappearance into the digital ether now defines us—we are the mediated people, whose contact with one another and the world around us is now mostly veiled by a screen. We threaten to rebel, just as we threaten to move to Canada after an election. But we don’t; the current is too fierce to swim to shore.
