existence of secret files are checked locally instead of remotely when using remote docker daemon with DOCKER_HOST #7857
Description
Description of the issue
I'm using an remote docker daemon (DOCKER_HOST is set). In my docker-compose.yml i have specified some secrets for use in my service. These secrets use a file that is only given on the remote system. Every time i use docker-compose on my local system it shows me a warning, that my service uses an undefined file. For my luck it is just a warning and the service starts and indeed uses the given files from the remote daemon.

Steps to reproduce the issue
- setup an remote docker daemon, that exposes the daemon port correctly
- install docker-cli and docker-compose locally
- specify DOCKER_HOST to the remote daemon
- configure a local docker-compose.yml file, that includes a configuration for a secret, which uses a file, that only exists on the remote system
- run the compose file
Observed result
i get a warning for the secret file
definition of remote volume works without warning
Expected result
i get a warning when the file is not present on the remote system and the local system should be ignored
Stacktrace / full error message
WARNING: Service "my_ser" uses an undefined secret file "/path/on/remote/system", the following file should be created "/path/on/remote/system"
Additional information
my remote system is a photon-os, my local system is ubuntu18.04 on WSL1
docker and docker-compose installed as documented
