docker-image-import - Import the contents from a tarball to create a filesystem image

docker image import [OPTIONS] file|URL|- [REPOSITORY[:TAG]]

Create a new filesystem image from the contents of a tarball (.tar, .tar.gz, .tgz, .bzip, .tar.xz, .txz) into it, then optionally tag it.

# docker image import http://example.com/exampleimage.tgz example/imagerepo

Import to docker via pipe and stdin:

# cat exampleimage.tgz | docker image import - example/imagelocal

Import with a commit message.

# cat exampleimage.tgz | docker image import --message "New image imported from tarball" - exampleimagelocal:new

Import to a Docker image from a local file.

# docker image import /path/to/exampleimage.tgz 

Import to docker via pipe and stdin:

# cat exampleimageV2.tgz | docker image import - example/imagelocal:V-2.0

# tar -c . | docker image import - exampleimagedir

This example sets the docker image ENV variable DEBUG to true by default.

# tar -c . | docker image import -c="ENV DEBUG true" - exampleimagedir

If the daemon supports multiple operating systems, and the image being imported does not match the default operating system, it may be necessary to add --platform. This would be necessary when importing a Linux image into a Windows daemon.

# docker image import --platform=linux .\linuximage.tar

docker-export(1) to export the contents of a filesystem as a tar archive to STDOUT.

-c, --change=
Apply Dockerfile instruction to the created image

-h, --help[=false]
help for import

-m, --message=""
Set commit message for imported image

--platform=""
Set platform if server is multi-platform capable
