How to solve the problem that docker redis cannot connect?

The application deployed to the docker container cannot connect to the redis container

##Each container run by docker is isolated. Redis does not allow external connections by default. Therefore, if you want to connect the application deployed in the docker container to redis, you need to modify the default configuration of redis. Here we can run redis with the configuration file.

Pull the redis container

docker pull redis

Specify the version number:

docker pull redis:4.0.9

Download and get the configuration file redis.conf from github

https://github. com/antirez/redis/releases

Download the redis release version, and select the version that matches the one in the container.
Get redis.conf, comment bind:127.0.0.1

Turn off protected mode

Run with configuration file

docker run -p 6379:6379 --name myredis -v /usr/local/docker/redis.conf:/etc/redis/redis.conf -d redis redis-server /etc/redis/redis.conf --appendonly yes

After successful startup , enter the redis container

docker exec -it myredis /bin/bash

View the ip assigned by docker to the container

cat /etc/hosts

When other containers connect to redis, you must change the 127.0.0.1 in the redis connection configuration to the ip you just found.
