 # `xena/alpine`
 
 This is a cut of Alpine Linux Edge with `runit(8)` for process supervision and zombie management. I use this for my projects when I can because it doesn't suck as much. Just do this like you would with Phusion's base image and everything will be fine.

-This also includes the [`backplane`](https://www.backplane.io) agent to make deployment easier. Usage:
-
-```console
-$ docker run \
-    -e BACKPLANE_TOKEN=<token> \
-    -e BACKPLANE_LABELS='hello:world' \
-    -e BACKPLANE_PROXY_URL=https://127.0.0.1:9090 \
-    xena/alpine
