TL,DR: beginner tries to set up NextCloud via docker components without having a domain. Trying to access via IP doesn’t work. Probably made a few mistakes/missed some important stuff along the way
Hi everyone,
I am completely new to self hosting. Like many others I want to move away from Google, Apple, Microsoft… for my Calendar, Tasks and Contacts, and I thought I would try self hosting all that in NextCloud. I have already tried a 3rd-party hosted NextCloud instance and I feel comfortable with it, so now I want to do the next step and host it myself on a RaspBerry Pi 4 (4GB) that I recently purchased.
I have read around and searched for tutorials, and although I am still a bit lost I decided I would start working on it and see what problems I find along the way, and learn from this. Once I’m done I hope to have learned properly, and I plan to wipe everything and do it again, this time knowing better what I’m doing.
So, to begin with I decided to do it using Docker Compose, as I’ve read it makes setup and troubleshooting easier. I found 2 tutorials that looked good to me: tutorial 1 and tutorial 2, but going through them I see the most frequent case they require that I have my own domain (tutorial 1 has only that option, tutorial 2 offers that option or using an IP address). Do I need to have my own domain to have NextCloud calendar, tasks and contacts shared between my computer and my smartphone? If both options are possible, is one of them more secure than the other? is there some strong reason to avoid one of them?
Since I don’t have a domain (I’m completely new to this), I opted to try tutorial 2 with IP address, but I got stuck in the end, where I am supposed to access my NextCloud Web Interface. Tutorial 2 suggests getting my Raspberry Pi IP address with hostname -I (step 17), but this way I get five different IP addresses (4 IPv4 and one IPv6), not just one. When I try any of those IPs on a browser (step 18) none of them work. I guess I am missing something basic here, so I’d be grateful if someone can point me in the right direction.
Searching for an answer I found a comment on reddit saying that I can skip getting a domain and host locally (no domain) and set up a VPN.
Would it be necessary in my case to get a domain? If I skip the domain, what steps am I missing to be able to access my current NextCloud docker installation? What mistakes have I made so far, and what resources can I use to learn about what I’m missing? Do you have any other tips for an absolute beginner (who is comfortable around the linux command line)?
At a glance your first issue is finding the correct ip address, you should only have one local ip address to access it with (inside your home network).
To find your local ip, type “ip a” into the terminal, and look for the address under “eth0“ for a wired connection, or “wlan0” for wireless. This will allow you to connect using the ip and port while on your home network to test the connection and make sure it works right.
After that, I highly recommend the vpn option, it will simplify connecting to it while not at home without creating security issues like setting it up with a domain. I personally use zerotier, that guide will help you get it set up on the raspberry pi. Not the last bit about a “managed ip.” That will be the address to tell your phone to connect too once you have the vpn set up on the phone as well.
