The formatting option (`--format`) will pretty print history output

using a Go template.
|

Valid placeholders for the Go template are listed below:
|
||||
|
||||
| Placeholder | Description|
|
||||
| ---- | ---- |
|
||||
| `.ID` | Image ID |
|
||||
| `.CreatedSince` | Elapsed time since the image was created if --human=true, otherwise timestamp of when image was created |
|
||||
| `.CreatedAt` | Timestamp of when image was created |
|
||||
| `.CreatedBy` | Command that was used to create the image |
|
||||
| `.Size` | Image disk size |
|
||||
| `.Comment` | Comment for image |

When using the `--format` option, the `history` command will either
|
||||
output the data exactly as the template declares or, when using the
|
||||
`table` directive, will include column headers as well.
|
||||
|
||||
The following example uses a template without headers and outputs the
|
||||
`ID` and `CreatedSince` entries separated by a colon for all images:
|
||||
|
||||
```bash
|
||||
{% raw %}
|
||||
$ docker images --format "{{.ID}}: {{.Created}} ago"
