I am used to mapping volumes to docker containers in the traditional sense:
/mnt/self-hosted/immich:/immich
/mnt/self-hosted/immich:/immich
However, Immich install guide says:
volumes: # Do not edit the next line. If you want to change the media storage location on your system, edit the value of UPLOAD_LOCATION in the .env file - ${UPLOAD_LOCATION}:/data
volumes: # Do not edit the next line. If you want to change the media storage location on your system, edit the value of UPLOAD_LOCATION in the .env file - ${UPLOAD_LOCATION}:/data
