How to build redis Cluster in docker

This article shows you how to build a redis cluster in docker. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

1. Create a virtual network card

Docker network create redis-net

3. Check the network card information

Docker network ls

4. View the redis-net virtual network card gateway ip

Docker network inspect redis-net | grep "Gateway" | grep-- color=auto-P'(\ d {1Magne 3}.) {3}\ d {1Magne 3}'- o

5. Create directories and files to be mounted

# create cluster mount directory mkdir-p / docker/redis# create cluster configuration file template touch / docker/redis/redis-cluster.conf# edit configuration file template content port ${PORT} cluster-enabled yescluster-config-file nodes.confcluster-node-timeout 5000cluster-announce-ip 192.168.100.101cluster-announce-port ${PORT} cluster-announce-bus-port 1 ${PORT} appendonly yes

6. Create a sh script file in the / docker/redis directory

Touch create_conf.sh

Edit the script as follows:

#! / bin/bashfor port in `seq 6001 6006`; domkdir-p. / ${port} / conf & & PORT=$ {port} envsubst

< ./redis-cluster.conf >

. / ${port} / conf/redis.conf & & mkdir-p. / ${port} / data;done

Authorized executable chmod-R 777 create_conf.sh

7. Execute the script to create the mount directory and configuration file

. / create_conf.sh

8. Edit the startup container script (start 6 containers)

Touch create_redis_docker.sh

Edit the content as

#! / bin/bashfor port in `seq 6001 6006` Dodocker run-d-ti-p ${port}: ${port}-p 1 ${port}: 1 ${port}-v / docker/redis/$ {port} / conf/redis.conf:/usr/local/etc/redis/redis.conf-v / docker/redis/$ {port} / data:/data-restart always-- name redis-$ {port}-net redis-net-- sysctl net.core.somaxconn=1024 redis redis-server / usr/local/etc/redis/redis.conf;done

Authorize chmod-R 777 create_redis_docker.sh

9. Execute the script to create the container

. / create_redis_docker.sh

10. View the ip of the created container

Docker inspect redis-6001 redis-6002 redis-6003 redis-6004 redis-6005 redis-6006 | grep IPAddress

11. Enter the 6001 port container

Docker exec-it redis-6001 bash

12. Execute cluster commands in the container

/ usr/local/bin/redis-cli-- cluster create 172.18.0.2 cluster-replicas 6001 172.18.0.3 VR 6002 172.18.0.4 VR 6003 172.18.0.5 cluster-replicas 6004 172.18.0.6 VR 6005 172.18.0.7 VR 6006--
