Hi,
I’d like to know whether it is possible to merge a list of volumes with an extension field in a compose file?
I have a few volumes which are common to all services, but then each service has its own additional volume.
The following doesn’t work:
version: "3.7"
x-function: &function
volumes:
- /var/run/docker.sock:/var/run/docker.sock
services:
myservice:
image: ubuntu
<<: *function
volumes:
- /dev:/dev:ro
myservice won’t get access to the Docker socket. I’ve also tried to add the *function inside the volumes
block, but it caused a syntax error.
Thanks in advance

Sadly, Docker is not able to beat the limitation yaml anchors and aliases have: no merge for lists!
