Thank you. I also found the tips here. I created a new user “photostructure” - got some info from Synology via SSH:
uid=1027(photostructure) gid=100(users) groups=100(users),65536(docker)
Setting environment variables for PUID and PGUID for a bunch of combinations (that user, 1026 which is user “reed”, GID vs Docker GID, using 0 to try and use root) - but haven’t yet been successful…
