Permissions for Output Directory

If you use a bind mount for the output directory, you may need to fix permissions so the container can write to it. Run this command on your host before running the container:

sudo chown -R 999:999 ./output

This sets the correct ownership for the libcartosym user inside the container.

Volumes

• ./data → /data (input files)
• ./output → /output (output files)
