Congrats! You and your coworkers love Docker. Docker has become an increasingly helpful tool when it comes to DevOps. We can now build smaller, more robust local development setups with the promise of mirroring production. One thing that still plagues many situations is how to get those containers into production and update them over time. We'll explore different tools for setting up, configuring, and maintaining containers as they go live.
