I’m having some difficulty utilizing the copyownershipfromparent
setting across two nodes.
Running the nodes as docker containers with root UID/GID to ensure they have chown/chmod permissions.
The docker-compose.yaml
on the first node is:
version: "3.4"
services:
syncthing:
container_name: syncthing
hostname: syncthing
image: syncthing/syncthing:latest
ports:
- "8384:8384"
- "21025:21025"
- "21025:21025/udp"
- "21027:21027"
- "21027:21027/udp"
- "22000:22000"
- "22000:22000/udp"
environment:
- "TZ=America/New_York"
- "GUID=0"
- "PUID=0"
volumes:
- "/docker/config/syncthing:/var/syncthing"
- "/docker/config/syncDir:/Sync/syncDir"
- "/etc/localtime:/etc/localtime:ro"
restart: unless-stopped
labels:
- "com.ouroboros.enable=true"
logging:
driver: json-file
options:
max-file: "3"
max-size: "10M"
And the config.xml
for the first node is:
<configuration version="36">
<folder id="mdvpi-nqscc" label="syncDir (data)" path="/Sync/syncDir/" type="sendonly" rescanIntervalS="3600" fsWatcherEnabled="true" fsWatcherDelayS="10" ignorePerms="false" autoNormalize="true">

On the second node, we have an identical docker-compose.yaml

Notably, both nodes have <copyOwnershipFromParent>true</copyOwnershipFromParent>
in both the folder settings, and the default folder settings. But when the files are sync’ed over, they appear on the second node with UID=0
and GID=1000
, despite them existing on the first node with a mix of UID=0
/GID=0
and UID=999
/GID=999
.
Any thoughts on where I’m going wrong to preserve UID/GID ownership across nodes?
