Currently the owner is working to improve the image with new feature (slack notification), but have network issue to push this big image.

So I made a new one with two changes:

1. build from latest codes to get new feature (slack notification)
2. re-build the image based on alpine-node image, reduce the size from 640MB to 64BM.

You'd better to always get the update images from its original source:

docker pull ndelitski/rancher-alarms
