If your Dockerized Grav CMS project isn't syncing changes between your local machine and the container, it's likely due to how Docker volumes are configured. This issue often arises when the volume mount replaces the container's directory with an empty local directory, leading to discrepancies between the container and local code. Stack Overflow

Solution: Proper Volume Mounting

To ensure seamless synchronization, you should mount only the necessary subdirectories instead of the entire Grav directory. Here's how you can adjust your docker-compose.yml file:

yaml Copy Edit services: grav: build: . container_name: grav ports:

• "8000:8000" volumes:
• ./grav/user:/var/www/html/user
• ./grav/config:/var/www/html/config
• ./grav/themes:/var/www/html/themes restart: unless-stopped By mounting specific subdirectories like user, config, and themes, you avoid overwriting the entire /var/www/html directory in the container, which can lead to the loss of essential files and configurations. This approach ensures that your local changes in these directories are reflected inside the container. Stack Overflow

Additional Tips

Avoid Mounting the Entire Directory: Mounting the entire Grav directory (./grav:/var/www/html) can overwrite container files with your local files, especially if the local directory is empty. Stack Overflow +1 Eric Stauffer +1

Use Named Volumes for Persistence: Consider using Docker named volumes for directories that require data persistence, such as logs or uploaded files.

Check File Permissions: Ensure that the user permissions on your local directories match those expected by the container to prevent permission-related issues. Grav Community Forum +2 Stack Overflow +2 Stack Overflow +2

Rebuild the Container if Necessary: If changes aren't reflecting, try rebuilding the container:

bash Copy Edit docker-compose down docker-compose up --build -d
