## Import from a local file
Import to docker via pipe and stdin:
# cat exampleimage.tgz | docker import - example/imagelocal
Import with a commit message.
# cat exampleimage.tgz | docker import --message "New image imported from tarball" - exampleimagelocal:new
Import to a Docker image from a local file.
# docker import /path/to/exampleimage.tgz
## Import from a local file and tag
Import to docker via pipe and stdin:
# cat exampleimageV2.tgz | docker import - example/imagelocal:V-2.0
## Import from a local directory
# tar -c . | docker import - exampleimagedir
## Apply specified Dockerfile instructions while importing the image
This example sets the docker image ENV variable DEBUG to true by default.
# tar -c . | docker import -c="ENV DEBUG true" - exampleimagedir
