The greatest advancement was that it was used straight from a Unix kernel, it didn't require any patches. It used control groups, namespaces, and a lot of what was built until then.

It was, at the time, the first and most complete implementation of a container management system. In 2008, LXC ( Linu X Containers) was launched. Jails were the first solution to expand the uses of chroot to allow not only the segregation at the filesystem level, but also virtualizing users, network, sub-systems and so on. Each jail can have its own IP config and system config. Jails allowed any FreeBSD users to partition the system into several independent, smaller systems (which are called jails). This solution was called jails, and it was one of the first real attempts to isolate stuff at the process level. In 2000, a hosting provider was searching for better ways to manage their customers' websites, since they were all installed in the same machine and competed for the same resources. But it was only two decades later when we had the first widespread application of it. This same syscall was introduced in BSD in 1982. In short, the process thinks it's running alone in the machine, because its file system is segregated from all other processes.

The chroot call allowed the kernel to change the apparent root directory of a process and its children. In 1979, the Unix version 7 introduced a system call called chroot, which was the very beginning of what we know today as process virtualization.

Did containers already exist in 1979? No! At that time, I wasn't even born, and my father was 15 years old. The history of containers begins in 1979 with Unix v7. This is mostly because they don't have to spin a whole operating system before running the process.ДЄnd this all began with six characters. While a VM can take about a minute to spin up and can weigh several Gigabytes, a container weighs, on average, 400 to 600mb (the biggest ones). This makes containers much smaller, faster, and more efficient. Difference between Virtual Machines and Docker Containers (Source: Docker) You can have several containers running within a single OS without having several different guest OS's installed. In other words, you don't need to have whole different OS (called guest OS) installed inside your host OS. What are containers?Д¬ontainers, or Linux Containers, are a technology that allows us to isolate certain kernel processes and trick them into thinking they're the only ones running in a completely new computer.Дifferent from Virtual Machines, a container can share the kernel of the operating system while only having their different binaries/libraries loaded with them. A lot of people think that Docker was the first of its kind, but this is not true вЂ“ Linux containers have existed since the 1970s.Дocker is important to both the development community and container community because it made using containers so easy that everyone started doing it. A Little Bit of Container HistoryДocker is a container runtime. And I'll summarize it here so we can focus on the important parts. I'll be using this amazing article by Rani Osnat that explains the whole history of containers in more depth. By the end, we'll also create, publish, and run our first Docker image.Д«ut first, let's lay the foundation for our story. We'll go on a journey to discover what is this Docker everyone is talking about and what you can do with it. If you have no idea of what I'm talking about, no worries вЂ“ that's what this article is for. And you're likely aware that it has become important tech for any application developer to know.

As a developer, you have probably heard of Docker at some point in your professional life.
