Docker is a robust platform that leverages lightweight containers, streamlining container management tasks for developers. With Docker, you can effortlessly create and deploy applications, which are analogous to images in traditional virtual machine environments, but tailored for containerization. By handling container provisioning and mitigating networking complexities, Docker simplifies the development process. Moreover, Docker offers a built-in registry functionality, enabling convenient storage and versioning of Docker applications
The Docker application abstraction proves beneficial as it shields us from the underlying technology utilized to implement the service, similar to VM images. We employ Docker applications generated through our service builds and store them within the Docker registry, allowing us to seamlessly proceed with our development process.
Docker can also alleviate some of the downsides of running lots of services locally for dev and test purposes. Rather than using Vagrant to host multiple independent VMs, each one containing its own service, we can host a single VM in Vagrant that runs a Docker instance. We then use Vagrant to set up and tear down the Docker platform itself, and use Docker for fast provisioning of individual services.
