One way to understand the concept of a container is to compare it to a virtual machine (VM).
DOCKER AND KUBERNETES IN AWS PORTABLE
A container stands alone it is abstracted away from the host operating system (OS) - usually Linux - which makes it portable across IT environments. What is a container?Ī container is an executable unit of software that packages application code with its dependencies, enabling it to run on any IT infrastructure. To do so, it’s important to start with the foundational technology that ties them together: containers. In this post, we’ll explore the fundamentals of Kubernetes and Docker and take a look at the advantages of using them individually and in tandem. And while they excel in their respective areas, they also are complementary and can be powerful when combined.
They are, in fact, fundamentally different technologies and don’t compete - it’s not an either/or question. A lot of people want to know which option is better, but that question is based upon a misconception. When it comes to container technologies, two names emerge as open source leaders: Kubernetes and Docker. This post looks at how the two powerful technologies can complement each other. Although many people want to compare Kubernetes and Docker, it's not actually an either/or question.
