Visiting Dependency Hell

Last night I was (trying) to install a Laravel project (DreamFactory) for evaluation. Normally I'm using Kalabox, a Docker-based project we created to help people quickly start developing and evaluating software. However, we didn't have an app configuration for Laravel. In my haste to "get things moving," I threw caution to the wind and began installing dependencies to run the project locally.

Big mistake.

The first hurdles were fairly innocuous: updating PHP, getting Composer in shape. When I hit my first real error (an issue with autom4te when building the mongodb php extension), I was a little taken aback, but not troubled. A bit of troubleshooting found out that my Xcode command line tools needed to be updated.

An hour and several errors later, I decided to call it quits when encountering a cryptically labeled "Error 1." I'm sure it was solvable: all problems are solvable with sufficient time.

Don't Live in Dependency Hell

Developers aren't always good sysadmins (I'm certainly no savant). Don't feel bad: if you're trying to run web applications natively on your Mac or Windows computer, likely you're wasting your time anyway. Afterall, who is running a MacOS or Windows 10 Pro server?

If you're a Linux user with extreme command-line fu, by all means: develop locally and love it. But for the rest of us who lack the time and inclination, make sure you visit Dependency Hell as infrequently as possible.

Home Sweet Container

My short vacation reminded me why the container world of Docker and Kalabox is such a great place for my day-to-day development to live. I have the help of a huge community providing container images that solve all the tricky sysadmin problems for me. I can run the same containers locally that are used in production, guaranteeing my local efforts aren't sound and fury signifying nothing.

Using DreamFactory's Docker Compose instructions I was able to get things up and going. And with a little tweaking, I was able to switch the datastore over to Postgres and import my dataset. Now I can use my work to host this DreamFactory installation on a wide variety of providers.

It isn't magic and there's still cursing, but I'll be damned if I ever get sent back down to Dependency Hell.
