Update docker setup

[fabarea]

Hi,

Your config looks interesting. Could you update the docker file and update the fig.yml (should be renamed to docker-compose.yml at the same time)? Currently it fails with:

make build
docker build --force-rm=true --no-cache=true -t cron/docker-typo3-cms .
Sending build context to Docker daemon 177.2 kB
