Under the LABEL section here https://docs.docker.com/engine/reference/builder/#label the command is incorrectly shown as:
docker image inspect --format='' myimage
screenshot:

when according to the Markdown source it should read:
docker image inspect --format='{{json .Config.Labels}}' myimage
It seems there is a bug in the docs website which renders markdown incorrectly when it includes literal {{ even inside triple-quoted code blocks.
