Cloudflare Zero Trust
I need to move some resources off of this virtual machine because I am running out of space. I can use a third party proxy to relocate services to other servers. The proxy could be the Cloudflare Zero Trust service. I should be able to completely eliminate the Varnish cache and reverse proxy running on this host and then I can move my wiki to an Oracle Cloud VM and then put a database replica on Bellman.
| What runs here? | Can I move it? | Where? | Notes |
|---|---|---|---|
| ssh | no | use a different dns name to access it | |
| wiki | yes | Oracle | Requires PHP and MySQL Replicate database on Bellman. Use webhooks to back up files. |
| hupi.org | yes | Oracle | Requires PHP |
| smtp | no | not worth it | |
| imap | no | not worth it | |
| Varnish | no |
WARP
Install a WARP client on Android it's called "Cloudflare One Agent", there is a separate WARP client but you don't need that.
WARP is the client side of a Zero Trust VPN client but routes all traffic from the device it's installed on through a proxy operated by Cloudflare. I put it on my tablet and my laptop. The laptop version allows selective use; this means I can decide which web sites get tunneled and which go direct.
Enabled swap
While I wait for the CS-1 to CS-2 upgrade, and while experiencing lockups due to memory exhaustion, I enabled swap.

Swap: 1048572 67156 981416
^^^^^ yep - doing "docker-compose up" hits swap space.
Packages installed
sudo certbot python-certbot-dns-cloudflare-doc python3-certbot-dns-cloudflare postfix postgrey
Docker installed from https://docs.docker.com/engine/install/debian/
I stood up an instance of nginx to get things tested using the command
docker run --name w6gkd -v /home/bwilson/html:/usr/share/nginx/html:ro -p 80:80 -d nginx
Since https://w6gkd.radio/ is proxied through Cloudflare I did not have to set up HTTPS. This is convenient. But it means traffic between Cloudflare and Tektonic is not encrypted yet.
