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:
$ docker history --format "{{.ID}}: {{.CreatedSince}}" busybox
