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:

PlaceholderDescription
.IDImage ID
.CreatedSinceElapsed time since the image was created if --human=true, otherwise timestamp of when image was created
.CreatedAtTimestamp of when image was created
.CreatedByCommand that was used to create the image
.SizeImage disk size
.CommentComment 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
