Error mounting file with remote docker context

[aphilas]

I am getting the error error mounting "/root/public/litesiem/core/elasticsearch/config/elasticsearch.yml" to rootfs at "/usr/share/elasticsearch/config/elasticsearch.yml" while trying to bring up a compose service on a remote host.

$ docker --version

Docker version 20.10.17, build 100c701

$ docker-compose --version

docker-compose version 1.29.2, build 5becea4c

$ docker context ls

ERROR: Encountered errors while bringing up the project.

What I have tried

• Deleting old containers/images for the service
• Deleting are re-rsyncing the config file/folder
• Removed the volume mount mode ro,z

P.S. I hope this is the right community forum for help related to Docker.

Solved by upgrading Compose, a la sudo apt-get install docker-compose-plugin

The full command to bring the service up is: ROOT=/root/public/litesiem/core docker --context remote compose -f docker-compose.yaml up elasticsearch.
