There is no risk of conflict with libraries that are installed by others.

Install your application, dependencies and environment variables one time into theĬontainer image rather than on each system you run on.In addition, the key benefits to using containers also include: One of the many benefits to using containers is that you can install your application,ĭependencies and environment variables one time into the container image rather than on each This saves spaceĪnd also greatly reduces the possibility of “version skew” so that layers that should be theĪ Docker container is the running instance of a Docker image. This reduces the time to create containers and also allows you to keepĭocker is also very good about keeping one copy of the layers on a system. If you make a change to a layer through a DockerFile (see Building Containers), than Docker rebuilds that layer and all subsequent layers but not the layers that are notĪffected by the build. You can think of layers as intermediate images that add some capability to the overallĬontainer.

The layers are combined to create the container. Systems uses Docker containers as the mechanism forĪ Docker container is composed of layers. Therefore, all kernel calls from the container are handled by the host system kernel.

Unlike a VM which has its own isolated kernel, containers use the host system kernel. Its libraries, data files, and environment variables so that the execution environment isĪlways the same, on whatever Linux system it runs and between instances on the same host. A Docker container is a mechanism for bundling a Linux application with all of
