Description

I have a Docker Compose service that mounts some project files as volume into the container

services:
  my-service:
    …
    volumes:
      - ./my-config1.yaml:/path/in/container/my-config1.yaml:ro
      - ./my-config2.yaml:/path/in/container/my-config2.yaml:ro

To the best of my knowledge, docker compose up my-service does not restart the container if it’s already up and running, even if my-config1.yaml or my-config2.yaml changed.

Since we are using Gradle with the gradle-docker-compose-plugin anyway, I would like to leverage Gradle to track input file changes and let trigger the Docker container recreation if necessary.

Is there a recommended way to achieve this or does even gradle-docker-compose-plugin support this feature out-of-the-box?

Research direction
Investigate the plugin's source code to see if it currently tracks input file changes for volumes. Look at the Gradle task implementation, possibly in the plugin's main class or task definitions. Determine if a custom task can be added that uses Gradle's built in input change tracking to detect volume file modifications and trigger container recreation. Check if there are any existing issues or PRs discussing similar functionality.
