Maestro is a docker orchestration tool built on top of NodeJS. It is designed to make scaling docker containers easy. All you need is a running consul deployment.
Easy deployments Transparent Docker Remote API arguments Discovery via consul Uses docker daemon, so no hidden crazyness. Uses labels to determine containers it is manageing Plugin Architecture
Deployments are not seperate from apps.
Unless you use an external deployment method, like git auto pull the docker image will not automatically update.
You can create a new app for deploys, and then scale down the old app as an alternative.
Also, new nodes added to the system may pull down a later version of the image then old nodes.
For this case we recommend always using tagging, and always only pushing to foreign when you are ready to do a deployment.
I plan to fix some of these issues by using a deployments object.
maestro-autoscale-node ( auto scale aws and containers based on node event loop lag ) ( first to be coded )
- how do we accomplish this -maybe peer process that jumps into each docker tagged with node and runs a pm2 describe and echo's out the evll. but that would be hard -maybe we force a contract, where a certain route is exposed on every container that provides evll -cleanest solution, but forces use of route -maybe we publish an npm module that can report back information to maestro -dirtier than route, and forces heavier rule maestro-autoscale ( auto scale aws and containers based on cpu and mem usage )
