You have some deb files
You want to be able to apt-get install them on systems
You want this to happen automatically (perhaps the debs are on a webdav share, or in github releases)

Status

Proof of concept. Neither fast, efficient, secure, neat, or featureful. Don't use in production unless you are really sure you know what you're doing and even then prepare to have your laundry eaten.

Contributing

Contributions welcome! You may find the Github mirror at https://github.com/wlcx/debanator easier if you're not already there.

Usage

debanator -debpath ./path/to/your/debs -httppass hunter2

For more, see -help.

Then, on the system you want packages on:

echo "deb http://debanator:hunter2@<host of debanator>:1612/ stable main
curl http://debanator:hunter2@<host of debanator>:1612/pubkey.gpg | apt-key add -
apt update
apt install your-package

Tailscale

Debanator supports listening inside a Tailscale tailnet as a "Virtual Private Service". To enable this mode, generate an auth key in the Tailscale admin panel and pass it as the TS_AUTHKEY env var. You can change the hostname debanator uses with -tailscalehostname.

Note that debanator still respects -listenaddr, which given you're inside a tailnet now you probably just want to set to :80.

Discussion

Yes, you could just use dpkg-scanpackages, but you'd have to write some script which did that, plus gpg and also fetched your packages from wherever they are.
