Hello, I’ve been looking at many guides but I’m having trouble understanding how to selfhost VaultWarden locally. Could someone help me understand how I could achieve this considering,
- I don’t have a domain
- It would be nice to do something like vaultwarden.local or vaultwarden.homelab.local instead of typing in the homelab’s pc static ip and the port vaultwarden is on
- I don’t want to expose anything outside of my local network
- Security reasons
- I am now well versed in networking so I don’t want to risk leaving an entry point for unwanted users or hackers
I also learned that I would need to sign certificates to be able to access it on some browsers and the additional security. I learned that Traefik offers self-signed certificates, but every video I have seen starts talking about needing a domain and cloudflare tunneling and I get lost.
It would be nice if I could get help or advice from the r/selfhosted community because I am new to all of this but want to learn and host more applications and services locally. Thank you.
Your router is exposed to public internet as long as it gets a public ip address. Domain is just an alias of ip easy to remember. Set strong policy on router will protects your local network on most scenarios.
What I did on self hosting is:
If you’re bothered to tweak config on router, you could also use Cloudflare’s tunnel, to manually add second level domain record for each service, if there are not many.
Besides, I use caddy to auto regenerate Let’s Encrypt’s certificate. It default requires that 80 port of you network is accessiable, not blocked by ISP. Or you can use dns verification in Let’s Encrypt’s config, just provide your domain provider’s API credential to it.
