### Format the output
|
||||
|
||||
The formatting option (`--format`) pretty-prints search output
|
||||
using a Go template.
|
||||
|
||||
Valid placeholders for the Go template are:
|
||||
|
||||
| Placeholder | Description |
|
||||
| -------------- | --------------------------------- |
|
||||
| `.Name` | Image Name |
|
||||
| `.Description` | Image description |
|
||||
| `.StarCount` | Number of stars for the image |
|
||||
| `.IsOfficial` | "OK" if image is official |
|
||||
| `.IsAutomated` | "OK" if image build was automated |
|
||||
|
||||
When you use the `--format` option, the `search` command will
|
||||
output the data exactly as the template declares. If you use the
|
||||
`table` directive, column headers are included as well.
|
||||
|
||||
The following example uses a template without headers and outputs the
|
||||
`Name` and `StarCount` entries separated by a colon for all images:
|
||||
