SYNOPSIS

DESCRIPTION

   List the changed files and directories in a container᾿s filesystem since the container was created. Three different types of change are tracked:

   ┌────────┬─────────────────────────────────┐
   │ Symbol │ Description                     │
   ├────────┼─────────────────────────────────┤
   │ A      │ A file or directory was added   │
   ├────────┼─────────────────────────────────┤
   │ D      │ A file or directory was deleted │
   ├────────┼─────────────────────────────────┤
   │ C      │ A file or directory was changed │
   └────────┴─────────────────────────────────┘

   You can use the full or shortened container ID or the container name set using docker run --name option.
