Docker runs processes in isolated containers. A container is a process that runs on a host. The host may be local or remote. When an operator executes docker run, the container process that runs is isolated in that it has its own file system, its own networking, and its own isolated process tree separate from the host.
The specific way to run it depends on whether you gave the image a tag or name.
To see if your docker image has a name, list the images using the docker images command and look for the tag or repository column:
docker images
Output:
REPOSITORY TAG ID CREATED SIZE
ubuntu 12.04 8dbd9e392a96 4 months ago 131.5 MB (virtual 131.5 MB)
To run a Docker image with a name, use the following syntax:
docker run -i -t ubuntu:12.04 /bin/bash
To run a Docker image with the image id, use the following syntax
docker run -i -t 8dbd9e392a96 /bin/bash
