#docker network create traefik

#Traefik creates an acme.json file with 755 and then promptly complains about too wide permissions
#Hence need for below janky fixing permissions
#Need a chmod 600 on the acme.json

#Traefik reverse proxy creates the SSL cert with 755 and then bombs with an error because the permissions are too open.
