this functionality in the 1.7 version. If you liked this functionality, you can
still find it in the third-party dockviz tool: https://github.com/justone/dockviz.
## Listing images in a desired format
When using the --format option, the image command will either output the data
exactly as the template declares or, when using the `table` directive, will
include column headers as well. You can use special characters like `\t` for
inserting tab spacing between columns.
The following example uses a template without headers and outputs the ID and
Repository entries separated by a colon for all images:
docker images --format "{{.ID}}: {{.Repository}}"
77af4d6b9913: <none>
b6fa739cedf5: committ
78a85c484bad: ipbabble
30557a29d5ab: docker
5ed6274db6ce: <none>
746b819f315e: postgres
746b819f315e: postgres
746b819f315e: postgres
746b819f315e: postgres
To list all images with their repository and tag in a table format you can use:
docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
IMAGE ID REPOSITORY TAG
