Query About Creating Volumes Without Services in Docker Compose v2 #10930
Description
Description
In Docker Compose v1, I was able to create volumes independently using the following syntax:
version: '3.2'
volumes:
volume1:
driver: local
name: "volume1"
However, upon migrating to Docker Compose v2, I attempted to use the same approach. Unfortunately, I encountered an error message "no service selected." It seems that the behavior has changed in v2 regarding how volumes are define
I'm looking for advice on how to create volumes in Docker Compose v2 without associating them with any specific service in Docker Compose v2. This was possible in v1, and I'm curious whether there's a workaround or new syntax in v2 that achieves the same result.
Steps To Reproduce
- Up Docker Compose with the YAML file using v1 syntax to define volumes.
Use the following YAML code:
version: '3.2'
volumes:
volume1:
driver: local
name: "volume1"
- Attempt to use the same file in Docker Compose v2 environment.
- Observe the "no service selected" error.
