Self-hosted blog - do I need a static IP address? (lemmy.ml)

hi everyone,

I was just about to self-host a Ghost blog but then was warned that my ISP might change my external IP address at any time, so I would need to pay for a static IP address.

Is that true?

(I'd not seen much about that in stuff I've looked up so far about self hosting)

How are you hosting? And do you have a domain? Lot's of good advice here, but knowing if you're running on a Pi, in Docker, etc, would help others give you the easiest/best method.

In short, you do not need a static IP.

Hi, I'm using Docker - one container for Ghost and one for Nginx Proxy Manager.

I've decided to go with DDNS but am having trouble choosing a reliable free provider. I've seen Dynu.com recommended but that is not available in the dropdown list of servers in my router's section on DDNS. Is that relevant?

Or would I just ignore the router settings and set it up some other way?

I'm having a good experience with cloudflare, using ddclient on a cron job

To clarify: it doesn't matter much what your router supports if you have a server with ddclient (possibly in Docker container). Then you can choose whatever provider you'd like, and there are tons of resources on ddclient.

If I install ddclient on my mini-pc is that what you mean by having a server with ddclient?

My Asus router is not shown in their docs as supported - does that matter?

Also - can I just keep using my current domain name registrar, and not use Cloudflare?

Cloudflare is a good choice. I used DNSExit for a while, and also NS1, but settled on Cloudflare. You don't have to use their proxying, just DNS.

Here's a Docker Compose for you that will set myhost.mydomain.com to point to your public IP of wherever it is run:

dyndns-cloudflare:
    image: oznu/cloudflare-ddns
    container_name: dyndns-cloudflare
    environment:
      - API_KEY=<key>
      - ZONE=mydomain.com
      - SUBDOMAIN=myhost
      - PROXIED=false
    restart: unless-stopped
