Is it possible to run multiple instances of Nextcloud on one machine with Docker? I’m a complete Docker newbie.
I am about to install NC on a Synology NAS with Docker using a mix of these intructions / tutorial and also these other ones and I’m wondering if I would be able to have two different instances running at the same time. Each would need to be accessible with its own IP address in my LAN so that I can configure the reverse proxy on the NAS to route traffic to the correct instance.
Yes. You can run any number of instances behind a reverse proxy. Depending on your network configuration, you may need to make sure they have unique ports.
it is definitely possible. I would recommend you to use different public hostnames e.g.
mycloud.tld
test-cloud.tld
mypartents-cloud.tld
and duplicate important infrastructure like DB and redis for every instance. you can share heavy applications like collabora and coturn if you use them…
The approach gives you a chance to separate the instances and have a way to test things without touching your production…
my setup with docker-compose looks like this
nc.mydomain.tld
dev-nc,mydomain.tld
are separate docker-compose files (identical besides hostnames and RAM) located in different folders. other containers like traefik (reverse proxy), dns, collabora and coturn run in separated docker-compose applications…
