How do I change default port in docker (on a Synology)

ℹ️ Support

Hi,

So how does one change a docker parameter to get Nextcloud working on a different port?
I looked up here as this is the image I’m using:

https://docs.linuxserver.io/images/docker-nextcloud#ports-p

But there is literally no way to add in the “-p” command anywhere in the docker interface under synology.

It seems Nextcloud is not supported on docker with synology?

You usually change the docker port within the docker-compose file although this could be done also at the command line. You’ll need to make sure if you are using a firewall this also allows for port ingress/egress. You would have to post some examples of your configuration in order to determine where things aren’t exactly working.

Thanks kevdog.

I was hoping I wouldn’t need to SSH in but here’s the json file from the docker image.
I highlighted in where I attempted to change the port but that line doesn’t seem to do anything.

Is that a docker compose file? Looks more like json?
