| |
| ### 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 the `busybox` image: |
| |
| ```bash |
| $ docker history --format "{{.ID}}: {{.CreatedSince}}" busybox |
