LibreNMS Docker Starting then Stopping

Hi there
Recently heading down the path of installing LibreNMS on my Synology NAS in Docker.

Upon starting it up it stays up for a second or so then stops.

The only information I see in the logs is as follows:
*** Running /etc/my_init.d/0_cron…

*** Running /etc/my_init.d/1_ssl…

*** Running /etc/my_init.d/2_ipv6…

*** Running /etc/my_init.d/3_timezone…

*** Running /etc/my_init.d/4_config…

WARNING: Detected deprecated config.custom.php file, please check the docs

*** Running /etc/my_init.d/5_environment…

*** Running /etc/my_init.d/6_permissions…

chown: changing ownership of ‘/opt/librenms/config.custom.php’: Read-only file system

*** /etc/my_init.d/6_permissions failed with status 1

*** Killing all processes…

Any clues would be great as I am at a loss as to what has been happening, have tried following the below site

Without any joy for some unknown reason.

I can’t say how to fix it but it’s because your file system is read only.

Thanks Iaf you sent me on the right path, updated the following:
-v /volume1/docker/librenms/config.custom.php:/opt/librenms/config.custom.php:ro \

to
-v /volume1/docker/librenms/config.custom.php:/opt/librenms/config.custom.php:rw \

Seems to be progressing.
