ERROR (catatonit:7): failed to exec pid1: Permission denied on docker-compose

i have a docker-compose file that when i try to start from,
immediately exits with
ERROR (catatonit:7): failed to exec pid1: Permission denied

The same docker-compose file was working earlier…
I’ve checked the following

  1. docker logs : this gives me the error i’ve reported.
  2. docker inspect : just dumps a json with unhealty.

I’ve restarted the docker service but no use.
Any idea where i can start looking ?
