redis-sentinel ha deploy for docker-compose

Redis-sentinel-with-docker-compose

redis-sentinel ha deploy using docker-compose with bridge mode, the example deploy the basic model: 1 master, 2 slave, 3 sentinel

ideas

The redis-sentinel ha deploy is progressive， please deploy master/slave first, then deploy redis sentinel with the master/slave bridge network, So the sentinels can communicate with all the redis master/slave nodes.

redis client apps

1. deploy in the same bridge network : The redis client apps can link the same above docker bridge network that can access the whole redis-sentinel
2. deploy independent

Sentinel, Docker, or other forms of Network Address Translation or Port Mapping should be mixed with care, The Docker offical provider a [force announce]

please force announce the redis-sentinel node ip and port with the machine Ip and bind port （not the above master container ip and cotainer expose ip）

The example show the redis container mapping 6380、6381、6382、26379、26380、26381 port

tip

1. please config the sentinel config using the master [container ip] in the first deploy time

when redis redis app deploy independence machine， please config the sentinel.conf with the machine ip and bind port

2. if you using requirepass set the client access pwd, please ensure usinng the masterauth set the replicas replication pwd
3. In the sentinel docker-copose.yml, if you have set the 'requirepass' for the master, please set the 'masterauth' for the master, because the master will become a slvae when failover，then it is also need a masterauth
