As we will see in the upcoming sections of this chapter, installing and using Docker is not difficult considering how much of a chore it was to maintain consistent environments in the past, even with automation, Docker feels a little too easy – almost like cheating. Programmers can continue to use their chosen integrated development environment ( IDE) and maintain their workflows when working with the code. We will be covering this in Chapter 2, Building Container Images, as well as Docker Compose files, which we will go into more detail about in Chapter 5, Docker Compose.

Using Docker for Mac or Docker for Windows, a developer can quickly wrap their code in a container that they have either defined themselves or created as a Dockerfile while working alongside a sysadmin or operations team. Everyone has their way of working and their own personal preferences-enforcing consistency across multiple platforms is difficult enough when a single engineer is working on the systems, let alone a team of engineers working with a team of potentially hundreds of developers. In an ideal world, everything should be consistent, from the developer's laptop all the way through to your production servers however, this utopia has traditionally been challenging to achieve. So, should the production environment be configured to match the developer's machine, or should developers only do their work in environments that match those used in production? Even if the versions match, you then have to deal with differences in the configuration and overall environment on which the version of PHP is running, such as differences in the way file permissions are handled between different operating system versions, to name just one potential problem.Īll of this comes to a head when it is time for a developer to deploy their code to the host, and it doesn't work. The problemĮven in a world where DevOps best practices are followed, it is still all too easy for a developer's working environment to not match the final production environment.įor example, a developer using the macOS version of, say, PHP will probably not be running the same version as the Linux server that hosts the production code. While it is funny, it is, unfortunately, an all-too-real problem and one I have personally been on the receiving end of, let's take a look at an example of what is meant by this. This problem is best summed up by an image, based on the Disaster Girl meme, which simply had the tagline ' Worked fine in dev, ops problem now', that started popping up in presentations, forums, and Slack channels a few years ago. The company behind Docker, also called Docker, has always described the program as fixing the ' it works on my machine' problem.

You'll also learn how to take control of your containers efficiently using Docker Compose, Docker Swarm, and Kubernetes.īy the end of this Docker book, you’ll have a broad yet detailed sense of what's possible with Docker and how seamlessly it fits in with a range of other platforms and tools.īefore we look at installing Docker, let's begin by getting an understanding of the problems that the Docker technology aims to solve. Once you've got to grips with Docker security, the book covers essential concepts for extending and integrating Docker in new and innovative ways. You'll start by building, managing, and storing images along with exploring best practices for working with Docker confidently. This fourth edition not only demonstrates how to use Docker more effectively but also helps you rethink and reimagine what you can achieve with it.

It has now grown into a key driver of innovation beyond system administration, with a significant impact on the world of web development. Docker has been a game changer when it comes to how modern applications are deployed and created.
