Display comments in the image history

   The docker commit command has a -m flag for adding comments to the image. These comments will be displayed in the image history.

   $ sudo docker history docker:scm

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, oth‐ │
   │               │ erwise 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 all images:

   $ docker images --format "{{.ID}}: {{.CreatedSince}} ago"
