Docker and the Path to a Better Staging Environment
Staging environments are notoriously difficult to set up and maintain. Unless you have a top-notch DevOps team, staging environments are usually different from production environments, and consequently, they are fraught with problems—failing deployments, "out of disk space" errors, and various other issues. Even when the staging environment is great, there's still a problem: There’s only one. If you want to test a feature branch, you must allocate time or, alternatively, install the feature branch and risk disrupting other testers. It’s time the testers took control about building their own testing environments, and we can do it using Docker, Docker-Compose, and Docker Swarm. Join Gil Tayar as he explains what Docker is and how to quickly deploy an app that includes a front end, backend service, and database, and he'll show how to run an end-to-end test on it. You'll return to your office with the ability to help developers change their code so that it can be deployed using a Docker setup, and you'll know how to execute the necessary changes to make the application deployable in such a setup.
