Format the output

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
