We can understand images as the building blocks from which containers are build, that way organizing the building of containers on a Docker environment. When we talk about containers on Docker, we talk about processes running from instructions that were set on images. What are those images for? That’s what we will find out on the next section. We can also see that the daemon is communicating with a image repository and using images while processing the requests. On the image above we can see the Docker clients connecting to the daemon, making requests to start/stop/create containers etc. The diagram bellow illustrates this architecture: The Docker architecture consists of a client-server model, where we have a Docker client, that could be the command line one provided by Docker, or a consumer of the RESTFul API also provided on the toolset, and the Docker server, also known as Docker daemon, which receives requests to create/start/stop containers, been responsible for the container management. By providing a logical layer that manages the lifecycle of the containers, we can focus our development on the applications themselves, leaving the implementation of the container management to Docker. So, without further delay, let’s begin do dive in on Docker, one of the most popular container engines on the market today.ĭocker was developed by Docker inc (formerly DotCloud inc) as a open-source engine for deployment of applications on containers. The fact is that containers are here to stay and his lightweight implementation provides a very good foundation for a lot of applications, such as a Microservices architecture. This is a very heated debate, which we can find a lot of discussion by the Internet.

Of course that using virtualization with hypervisors over containers has his benefits too, such as more flexibility – since you can’t for example run a windows container from a linux machine – and security, since this shared kernel approach leads to a scenario where if a attacker invades the kernel, he automatically get access to all the containers provided by that kernel, although we can say the same if the attacker invades the hypervisor of a machine running some VMs. This leads to a much more lightweight virtualization, allowing us to run a lot more VMs on a single host then we could do with a hypervisor. On containers, however, we don’t have this hypervisor layer. Instead, containers run directly on top of the kernel itself of the host machine they are running. This technologies, however, use hypervisors, which creates a intermediate layer responsible for isolating the virtual machine from the physical machine.
In this world, there is several traditional technologies such as VMWare, Virtualbox, etc.

Virtualization, as the name implies, consists in the use of software to emulate any part of a environment, ranging from hardware components to a entire OS. But after all, what it is virtualization? On this post, we will talk about the virtualization technology called Docker, which gained a ton of popularity this days, specially when we talk about Microservices architectures.
