## Docker save
|
||
|
|
|
||
|
|
`docker save` stores a Docker image to a tar archive. It is useful to make an offline backup of an image or transfer an image to a computer in a corporate environment which does not have a direct access to the Internet.
|
||
|
|
|
||
|
|
For example, to save the nginx image already in local computer to a file named `nginx-backup.tar`, the following command can be run:
|
||
|
|
|
||
|
|
```
|
||
|
|
docker save -o nginx-backup.tar nginx
|
||
|
|
```
|
||
|
|
|
||
|
|
Or with a specific version:
|
||
|
|
|
||
|
|
```
|
||
|
|
docker save -o nginx-backup.tar nginx:1.15.5
|
||
|
|
```
|
||
|
|
|
