## Description
|
|
|
|
Produces a tarred repository to the standard output stream.
|
|
Contains all parent layers, and all tags + versions, or specified `repo:tag`, for
|
|
each argument provided.
|
|
|
|
## Examples
|
|
|
|
### Create a backup that can then be used with `docker load`.
|
|
|
|
```console
|
|
$ docker save busybox > busybox.tar
|
|
|
|
$ ls -sh busybox.tar
|
|
|
|
2.7M busybox.tar
|
|
|
|
$ docker save --output busybox.tar busybox
|
|
|
|
$ ls -sh busybox.tar
|
|
|
|
2.7M busybox.tar
|
|
|
|
$ docker save -o fedora-all.tar fedora
|
|
|
|
$ docker save -o fedora-latest.tar fedora:latest
|
|
```
|
|
|
|
### Save an image to a tar.gz file using gzip
|
|
|
|
You can use gzip to save the image file and make the backup smaller.
|
|
|
|
```console
|
|
$ docker save myimage:latest | gzip > myimage_latest.tar.gz
|
|
```
|
|
|
|
### Cherry-pick particular tags
|
|
|
|
You can even cherry-pick particular tags of an image repository.
|
|
|
|
```console
|
|
$ docker save -o ubuntu.tar ubuntu:lucid ubuntu:saucy
|
|
```
