Isolated application execution with Docker
211/258
Image
An image is the basis for a container and includes only its program code
and basic settings.
It does not include information the program code generates on a storage
medium or RAM while it is running.
Moreover, it does not include any information on the environment the image
is to be executed in, i.e. it is platform-neutral.
An image always relates to the defined processor architecture it is compiled
for, e.g. x86, x64 or ARM. If a container is generated from an image, make
sure that the image is suitable for the hardware platform used.
For distributing images via the Internet, the Docker organization provides a
so-called repository under
. Images stored there
are freely accessible. Users can also manage their own repositories.
Note:
For more information on images, see the Docker documentation
https://docs.docker.com/engine/docker-overview/%23docker-
objects
and, in particular, its glossary
.
