Example of deploying Redis cluster3.2.5 cluster using Docker

As before, redis is a stable version 3.2.5 with alpine.

[Root @ LinuxEA redis1] # cat Dockerfile
FROM alpine

RUN apk update \
& Apk -- no-cache add curl \
& Curl-sO http://download.redis.io/releases/redis-3.2.5.tar.gz \

EXPOSE 6379/tcp 6380/tcp 16379/tcp 16380/tcp
ENTRYPOINT/usr/local/redis/bin/redis-server/etc/redis. conf
Now we build docker and then provide it to other machines in a repository:
Docker build-t redis3.2.5.
Docker tag reids3 10.10.242.23: 5000/alpinedocker push 10.10.242.23: 5000/alpine'
Docker warehouse usage, refer to the blog docker warehouse building article: http://www.111cn.net/1424.html

We usually need six hosts, three master nodes and three slave nodes. We use three hosts and two redis containers for each host. After the cluster is complete, two apsaradb for redis instances on each host are not the same master/slave
Configuration File example: we need to modify the port number, IP address, and pid name. Here, the IP address uses the docker hosts mode, which will be much simpler. The topology is as follows:

After the modification, run the docker of the three servers.

We simply add a rule to allow: iptables-I INPUT-p tcp-j ACCEPT
Now we can create a cluster!
