## Description
|
|
|
|
|
|
2015-07-25 08:07:24 -04:00
|
|
|
|
You can specify a `URL` or `-` (dash) to take data directly from `STDIN`. The
|
|
|
|
|
`URL` can point to an archive (.tar, .tar.gz, .tgz, .bzip, .tar.xz, or .txz)
|
2015-07-28 01:12:01 -04:00
|
|
|
|
containing a filesystem or to an individual file on the Docker host. If you
|
2015-07-25 08:07:24 -04:00
|
|
|
|
specify an archive, Docker untars it in the container relative to the `/`
|
|
|
|
|
(root). If you specify an individual file, you must specify the full path within
|
|
|
|
|
the host. To import from a remote location, specify a `URI` that begins with the
|
|
|
|
|
`http://` or `https://` protocol.
|
2015-06-21 16:41:38 -04:00
|
|
|
|
|
|
|
|
|
The `--change` option will apply `Dockerfile` instructions to the image
|
|
|
|
|
that is created.
|
|
|
|
|
Supported `Dockerfile` instructions:
|
|
|
|
|
`CMD`|`ENTRYPOINT`|`ENV`|`EXPOSE`|`ONBUILD`|`USER`|`VOLUME`|`WORKDIR`
|
|
|
|
|
|
|
|
|

|
|
2017-02-07 18:42:48 -05:00
|
|
|
|
```bash
|
2015-07-25 08:07:24 -04:00
|
|
|
|
$ docker import /path/to/exampleimage.tgz
|

|
|
|
### Import from a local directory
|
2015-06-21 16:41:38 -04:00
|
|
|
|
|
2017-02-07 18:42:48 -05:00
|
|
|
|
```bash
|
|
|
|
|
$ sudo tar -c . | docker import - exampleimagedir
|
|
|
|
|
```
|
2015-06-21 16:41:38 -04:00
|
|
|
|
|
2017-02-07 18:42:48 -05:00
|
|
|
|
### Import from a local directory with new configurations
|
2015-06-21 16:41:38 -04:00
|
|
|
|
|
2017-02-07 18:42:48 -05:00
|
|
|
|
```bash
|
|
|
|
|
$ sudo tar -c . | docker import --change "ENV DEBUG true" - exampleimagedir
|
|
|
|
|
```
|
2015-06-21 16:41:38 -04:00
|
|
|
|
|
|
|
|
|
Note the `sudo` in this example – you must preserve
|
|
|
|
|
the ownership of the files (especially root ownership) during the
|
|
|
|
|
archiving with tar. If you are not root (or the sudo command) when you
|
|
|
|
|
tar, then the ownerships might not get preserved.

## When the daemon supports multiple operating systems
|
|
|
|
|
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 import --platform=linux .\linuximage.tar
|
