i trying to use docker-ssh with an ubuntu docker container, but get this error:
invalid reference format: repository name must be lowercase.

my command:
docker run --name sshd-testsystem -p 1333:22 -v /var/run/docker.sock:/var/run/docker.sock -e AUTH_MECHANISM=noAuth -e FILTERS={\"name\":[\"^/mytestsystem$\"]} jeroenpeeters/docker-ssh

the error occures when i set the FILTERS paramter.
What i'am doing wrong?
