It is also an excellent feature for software developers running tests on their system since any data entered would be deleted, and the test run would start fresh each time. This is great to ensure that the application always runs consistently. When a container is restarted, it will always be the same, and any change that might have occurred while it was running is now gone.

Orchestration tools such as Kubernetes also make it simple to upgrade unique microservices without any downtime.Īnother benefit of using containers is that they are ephemeral in nature. Containers also make it possible to have small microservices running together side by side. Their small footprint makes it easy to run multiple self-contained and isolated applications. Therefore, the total cost of running an application as a container is much smaller than running it on a virtual machine.Ĭontainer technology is also at the heart of the microservices revolution in software development. This has the benefit of significantly reducing the resources needed to run compared to virtual machines, which require a full operating system of their own. Thanks to that engine, a container can run uniformly on Linux, macOS, and Windows.Ĭontainers run as single processes on the Docker engine.Ĭontainers run in their own isolated processes in a given user space. Docker popularized the concept of containers when they introduced the Docker Engine, which lets containers run on any operating system.
Containers are a way to isolate everything needed to run an application in its environment. This was the beginning of process isolation.įast forward a few years, and you get the state of containers as they are today. The chroot command was introduced as part of the operating system, which changes the root directory of a process and its children. It finds its roots with the advent of the Unix operating system. The concept of containers dates back to the ’70s. Docker is a tool to run those containers.

Imagine a big zip file that would include everything needed to run your application on any operating system or hardware.
A Docker container is a single unit containing an application and all of its necessary configurations or dependencies.
