38To see how the `docker:apache` image was added to a container's base image:

40```console
41$ docker history docker:scm

49### <a name="format"></a> Format the output (--format)
50
51The formatting option (`--format`) will pretty-prints history output
52using a Go template.
53
54Valid 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
65When using the `--format` option, the `history` command either
66outputs the data exactly as the template declares or, when using the
67`table` directive, includes column headers as well.
68
69The following example uses a template without headers and outputs the
70`ID` and `CreatedSince` entries separated by a colon (`:`) for the `busybox`
71image:
72
73```console
74$ docker history --format "{{.ID}}: {{.CreatedSince}}" busybox
