Format the output (--format)

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 either outputs the data exactly as the template declares or, when using the table directive, includes 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
