gyne 🐝🐜

gyne, the insect queen, is a declarative interface to manage a Docker swarm

npm install --save gyne

overview

given you have a config.yml that declares the complete state of your Docker swarm (including nested stacks),

you run:

gyne up config.yml

first, you will be shown the diff between the inspected state of the swarm and your declared state.

you are given a choice to accept or decline the patch.

if you accept, the Docker swarm will be updated to the declared state.

example

npm install -g gyne
git clone [e-mail]:buttcloud/gyne

# bring up your docker swarm 
gyne up example/config.yml
# check out your docker swarm! 
docker service ls
