Automatic cluster manager for Redis Cluster
This project is created for educational purposes only, this piece of software is not production ready.
- Expose cluster metrics for cluster monitoring
- Track cluster incidents within a reasonable time
- Choose a set of incidents and focus on solving each one as fast as possible
The cluster manager consists of multiple services.
- manager - The primary coordinator service responsible for orchestrating cluster operations
- agent - Metric collector and coordinator for each Redis instance
The agent service runs as a sidecar deployed together with each Redis instance. Only one manager should run at the time.

You need to have the go toolchain installed to build this project.
git clone git@github.com:eirsyl/apollo.git $GOPATH/src/github.com/eirsyl/apollo
make
The compiled artifact is located in the bin/ folder.
Apollo supports the following management tasks:
- Cluster creation
- Open slot
- Slot coverage
- Node addition
- Balance cluster
- Monitoring (prometheus exporter)
The Apollo agents exposes a set of Redis metrics via the http server. The metrics are located on the /metrics
endpoint in the Prometheus metrics format. The dashboards folder contains a Grafana dashboard for monitoring
of the Redis nodes.
