These can include operating system utilities and other applications that support your main app. What is a Docker container?Ī Docker container is a packaging technology which allows you to distribute not just the app itself, but also all of its dependencies, such as the environment that app required.
Docker allows you to configure run time environments for each application in exactly the same way as that app requires it, without affecting how other applications run, so in our example each application could run its “favorite” version of Python. Docker and software packagingĮver tried to install a utility and was not able to because it depended on some version of Python to be present on your computer? This was the original problem Docker was meant help with. While we often here about Docker vs Kubernetes, because the two technologies have some overlapping features, it’s more helpful to think of them as complimenting each other, than competing with each other. While the Kubernetes architecture is open enough to allow for running multiple container platforms, most virtual environments that run Kubernetes do so with Docker provided. highly automated applications designed specifically for the cloud, as defined by the Cloud Native Computing Foundation. Docker and Kubernetes together has quickly become the de facto standard for cloud native applications, i.
