## Asus router
|
|
Access via https://router.asus.com.
|
|
|
|
## How DNS works
|
|
We use pihole running on a raspberrypi 3B connected via `eth` to the router. This is used so that we can use domain names to point to devices in the local network. You can view the DNS records in the [pi-hole admin panel](http://pi.hole/admin).
|
|
|
|
_Password stored in firefox._
|
|
|
|
Note: we are not using pi-hole as a DHCP server. We leave this to the router, although we should likely use the pi-hole server for this.
|
|
|
|
### Discoveries
|
|
1. Do not have a secondary DNS server in router config. This makes pi-hole local DNS not work.
|
|
2. Do not use `.local` for domain in local DNS. You will see a warning when using dig that `.local` is reserved for mDNS.
|
|
|
|
## Container registry
|
|
For saving docker images. We run a private registry.
|
|
|
|
_Ask Arjun to add another user for you._
|
|
username: talksik
|
|
password: (it's typical arjun)
|
|
|
|
Used [this](https://www.digitalocean.com/community/tutorials/how-to-set-up-a-private-docker-registry-on-ubuntu-20-04) guide to get a private docker registry running, in docker.
|
|
|
|
Given that the reverse-proxy works and domain works, hitting `https://registry.flowy.live/v2/_catalog` and entering credentials should return list of repositories.
|
|
|
|
## Reverse-proxy
|
|
We run our reverse-proxy on homelab1 or talksik-homelab-main.
|
|
|
|
The current configuration is at `[email protected]:/etc/nginx/nginx.conf` as one would expect. However, we have a (likely stale) copy in `./reverse-proxy`.
|
|
|
|
## Kubernetes
|
|
Using k3s. Lightweight, easy system service.
|
|
|
|
Make sure you have static ip for each node.
|
|
|
|
### Grafana and prometheus
