First container start without existing folders / wrong chmod fails to create assets about nginx-sso

[Luzifer]

Hm indeed there is something if the data folder does not exist / has the wrong permissions:

# docker run -d --name nginx-sso -p 127.0.0.1:8082:8082 -v /tmp/sso-config:/data luzifer/nginx-sso

# docker logs nginx-sso
cp: can't create directory '/data/frontend': Permission denied

# sudo mkdir /tmp/sso-config/frontend
# sudo chown -R 1000:1000 /tmp/sso-config/

# docker rm nginx-sso
nginx-sso

# docker run -d --name nginx-sso -p 127.0.0.1:8082:8082 -v /tmp/sso-config:/data luzifer/nginx-sso

# docker logs nginx-sso
An example configuration was copied to /data/config.yaml - You want to edit that one!

# lt /tmp/sso-config
drwxr-xr-x    - luzifer luzifer 27 Mar 21:10 /tmp/sso-config
.rw-r--r-- 5.0k luzifer luzifer 27 Mar 21:10 ├── config.yaml
drwxr-xr-x    - luzifer luzifer 27 Mar 21:10 └── frontend
.rw-r--r-- 5.4k luzifer luzifer 27 Mar 21:10    └── index.html

Try creating the /data/sso-config/frontend dir and chown -R 1000:1000 /data/sso-config before running the container.

After you've edited the config you need to start the container again (when generating the example config it will exit afterwards as you probably don't want to work with those defaults).

I'm assigning this issue to the v1.x Milestone to build a proper fix in there.

Thanks for the quick reply! And the spot-on troubleshooting. That was exactly the issue.

I created the directories and adjusted the permissions and the logs reflect that the example configuration file was created.
