# import
|
|||
|
|
|
|||
|
|
Usage: docker import URL|- [REPOSITORY[:TAG]]
|
|||
|
|
|
|||
|
|
Create an empty filesystem image and import the contents of the
|
|||
|
|
tarball (.tar, .tar.gz, .tgz, .bzip, .tar.xz, .txz) into it, then
|
|||
|
|
optionally tag it.
|
|||
|
|
|
|||
|
|
-c, --change=[] Apply specified Dockerfile instructions while importing the image
|
|||
|
|
|
|||
|
|
URLs must start with `http` and point to a single file archive (.tar,
|
|||
|
|
.tar.gz, .tgz, .bzip, .tar.xz, or .txz) containing a root filesystem. If
|
|||
|
|
you would like to import from a local directory or archive, you can use
|
|||
|
|
the `-` parameter to take the data from `STDIN`.
|
|||
|
|
|
|||
|
|
The `--change` option will apply `Dockerfile` instructions to the image
|
|||
|
|
that is created.
|
|||
|
|
Supported `Dockerfile` instructions:
|
|||
|
|
`CMD`|`ENTRYPOINT`|`ENV`|`EXPOSE`|`ONBUILD`|`USER`|`VOLUME`|`WORKDIR`
|
|||
|
|
|
|||
|
|
## Examples
|
|||
|
|
|
|||
|
|
**Import from a remote location:**
|
|||
|
|
|
|||
|
|
This will create a new untagged image.
|
|||
|
|
|
|||
|
|
$ docker import http://example.com/exampleimage.tgz
|
|||
|
|
|
|||
|
|
**Import from a local file:**
|
|||
|
|
|
|||
|
|
Import to docker via pipe and `STDIN`.
|
|||
|
|
|
|||
|
|
$ cat exampleimage.tgz | docker import - exampleimagelocal:new
|
|||
|
|
|
|||
|
|
**Import from a local directory:**
|
|||
|
|
|
|||
|
|
$ sudo tar -c . | docker import - exampleimagedir
|
|||
|
|
|
|||
|
|
**Import from a local directory with new configurations:**
|
|||
|
|
|
|||
|
|
$ sudo tar -c . | docker import --change "ENV DEBUG true" - exampleimagedir
|
|||
|
|
|
|||
|
|
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.
