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
