Redis pod-manager using Fabric

POD-MANAGER

This simple tool uses Fabric to automate the creation of new Redis Pods running on Docker containers. It can run using a pre-defined hosts list or fetch them dynamically from AWS.

Requirements

  • Python 2.7
  • Fabric

Install

pip install fabric

Configure

config.yml

  • ssh_user: the username you are going to use to login in redis instances
  • ssh_key: path to ssh key
  • fetch_mode: can be static or dynamic, depending if you have a static set of hosts (sentinels and redis), or if you are going to fetch them though AWS API.
  • sentinel.key: the AWS tag key you have defined for sentinels
  • sentinel.value: the AWS tag value you defined for sentinels
  • redis.key: same as above but for redis hosts
  • redis.value: same as above but for redis hosts

hosts.yml

Use this file if you have set fetch_mode: static on config.yml.

Something like:

---
sentinels:
    172.22.41.15
    172.22.42.15
    172.22.43.15
redis:
    172.22.41.27
    172.22.41.133
    172.22.42.122
    172.22.42.239
    172.22.43.81
    172.22.43.48

Usage

Task list

fab -l

New Pod

fab podName:<YOURPODNAME>,<REDISPORT>,<CLUSTER>

ie:

fab podName:colossus,7190,redis-cluster-2

TODO

  • Discovery using AWS API / boto
  • Validations about container name and port
  • define more than one cluster on hosts.yml
