    24  To see how the `docker:latest` image was built:

    38  To see how the `docker:apache` image was added to a container's base image:
    39  
    40  ```console
    41  $ docker history docker:scm

    49  ### <a name="format"></a> Format the output (--format)
    50  
    51  The formatting option (`--format`) will pretty-prints history output
    52  using a Go template.
    53  
    54  Valid placeholders for the Go template are listed below:
    55  
    56  | Placeholder     | Description                                                                                               |
    57  |-----------------|-----------------------------------------------------------------------------------------------------------|
    58  | `.ID`           | Image ID                                                                                                  |
    59  | `.CreatedSince` | Elapsed time since the image was created if `--human=true`, otherwise timestamp of when image was created |
    60  | `.CreatedAt`    | Timestamp of when image was created                                                                       |
    61  | `.CreatedBy`    | Command that was used to create the image                                                                 |
    62  | `.Size`         | Image disk size                                                                                           |
    63  | `.Comment`      | Comment for image                                                                                         |
    64  
    65  When using the `--format` option, the `history` command either
    66  outputs the data exactly as the template declares or, when using the
    67  `table` directive, includes column headers as well.
    68  
    69  The following example uses a template without headers and outputs the
    70  `ID` and `CreatedSince` entries separated by a colon (`:`) for the `busybox`
    71  image:
    72  
    73  ```console
    74  $ docker history --format "{{.ID}}: {{.CreatedSince}}" busybox
