Error message when running mongo container - mongodb

Question

I have currently a problem with mongoDB and Docker:
I have this error when I compose up:
ERROR: Named volume "mongo:/data/db:rw" is used in service "mongo" but no declaration was found in the volumes section.

Answer 1

In fact, i realized that i have a volume instead a container but i can't access to the data or manipulate them with the mongo shell.
I have to delete an index from one mongodb collection in the volume.
How i can do that knowing that i have no container but i have a volume instead.
