List labels for a docker container

docker-inspect.sh

docker inspect -f '{{ range $k, $v := .ContainerConfig.Labels -}}
{{ $k }}={{ $v }}
{{ end -}}' $cid

To imrpove readbility and easier spot empty labels I would add a semicolon after {{ $k }}={{ $v }}:

docker inspect -f '{{ range $k, $v := .Config.Labels -}}
{{ $k }}={{ $v }};
{{ end -}}' $cid

Or if you don't mind json output: docker inspect -f "{{json .Config.Labels}}" $cid
