|
### Format the output
|
|
|
|
The formatting option (`--format`) will pretty-prints 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
|
|
$ docker images --format "{{.ID}}: {{.Created}} ago"
