Method of building redis cluster based on docker

Download the redis image

docker pull yyyyttttwwww/redis

Take an alias

docker tag docker.io/yyyyttttwwww/redis redis

Delete the original image tag

docker rmi docker.io/yyyyttttwwww/redis

Start the redis container of 6 nodes. Note that the network used is net1.

docker run -it -d --name r1 -p 5001:6379 --net=net1 --ip 172.19.0.101 redis bash
docker run -it -d --name r2 -p 5002:6379 --net=net1 --ip 172.19.0.102 redis bash
docker run -it -d --name r3 -p 5003:6379 --net=net1 --ip 172.19.0.103 redis bash
docker run -it -d --name r4 -p 5004:6379 --net=net1 --ip 172.19.0.104 redis bash
docker run -it -d --name r5 -p 5005:6379 --net=net1 --ip 172.19.0.105 redis bash
docker run -it -d --name r6 -p 5006:6379 --net=net1 --ip 172.19.0.106 redis bash

The created containers are not started by default, so they need to be started one by one

docker exec -it -u 0 r1 bash
/usr/redis/src/redis-server /usr/redis/redis.conf
exit
 
docker exec -it -u 0 r2 bash
/usr/redis/src/redis-server /usr/redis/redis.conf
exit
 
docker exec -it -u 0 r3 bash
/usr/redis/src/redis-server /usr/redis/redis.conf
exit
 
docker exec -it -u 0 r4 bash
/usr/redis/src/redis-server /usr/redis/redis.conf
exit
 
docker exec -it -u 0 r5 bash
/usr/redis/src/redis-server /usr/redis/redis.conf
exit
 
docker exec -it -u 0 r6 bash
/usr/redis/src/redis-server /usr/redis/redis.conf
exit

Enter any container such as r1 and start the cluster using the ruby script

docker exec -it -u 0 r1 bash
 
/usr/redis/src/redis-trib.rb create --replicas 1 172.19.0.101:6379 172.19.0.102:6379 172.19.0.103:6379 172.19.0.104:6379 172.19.0.105:6379 172.19.0.106:6379

Enter yes to create successfully. The terminal output effect when executing the script is as follows:

Enter the command line of a node to connect to the redis cluster and check the cluster status

You can see that there are 3 master nodes and 3 slave nodes
