  For loops with find are evil for a lot of reasons, one of which is spaces:

  $ tree
  .
  ├── arent good with find loops
  │   ├── a
  │   └── innerdira
  │       └── docker-compose.yml
  └── dirs with spaces
      ├── b
      └── innerdirb
          └── docker-compose.yml
  
  3 directories, 2 files
  $ for y in $(find .); do echo $y; done
  .
  ./are
  t good with fi
  d loops
  ./are
  t good with fi
  d loops/i
  
  erdira
  ./are
  t good with fi
  d loops/i
  
  erdira/docker-compose.yml
  ./are
  t good with fi
  d loops/a
  ./dirs with spaces
  ./dirs with spaces/i
  
  erdirb
  ./dirs with spaces/i
  
  erdirb/docker-compose.yml
  ./dirs with spaces/b
  

  You can kinda fix that with IFS:

  $ OIFS=$IFS
  $ IFS=$'\n'
  $ for y in $(find .); do echo "$y"; done
  .
  ./arent good with find loops
  ./arent good with find loops/innerdira
  ./arent good with find loops/innerdira/docker-compose.yml
  ./arent good with find loops/a
  ./dirs with spaces
  ./dirs with spaces/innerdirb
  ./dirs with spaces/innerdirb/docker-compose.yml
  ./dirs with spaces/b
  $ IFS=$OIFS
  

  But you can also use something like:

  find . -name 'docker-compose.yml' -printf '%h\0' | xargs -0 ...
  

  or in your case this could work:

  find . -name 'docker-compose.yml' -execdir ...

  I hope the real version doesn’t have the spelling problem!
