How to deploy and start redis in docker

Start Docker in Centos7
 systemctl start docker //Start docker
 systemctl stop docker //Stop docker
 systemctl restart docker //Restart docker

docker pull redis //Do not specify a version number, pull the latest one by default.
docker pull redis:6.0.8

docker images
docker rmi image ID //delete the image

The redis.conf configuration file can be downloaded at http://download.redis.io/redis-stable/redis.conf

Use mkdir /usr/local/docker to create a docker directory on the host machine. vi /usr/local/docker/redis.conf to create the redis configuration file redis.conf in docker.
Replace the downloaded redis.conf file or copy the content to the configuration file you created and then modify the configuration bind 127.0.0.1 //127.0.0.1 restricts access to the local machine only and changes it to 0.0.0.0

protected-mode no # The default is yes, which turns on protected mode and limits access to local devices daemonize no The default is no, and changing to yes means starting redis as a daemon process. Yes will cause the configuration file to fail to start redis (it will exit as soon as it is turned on)

1. $ docker run -itd --name redis-test -p 6379:6379 redis

2. $ docker run -itd -p 192.168.220.129:6379:6379 --name redis -v /usr/local/docker/redis.conf:/etc/redis/redis.conf -v /usr/local/docker/data:/data redis redis-server /etc/redis/redis.conf 

-d Run as a daemon thread (background run)
-i runs the container in interactive mode -t reallocates a pseudo input terminal for the container -p maps port 6379 of the container service to port 6379 of the host machine. The outside world can directly access the Redis service through the host ip:6379.

 //It may not work without -it because, for Docker container to run in the background, there must be a foreground process. The commands run by the container are not those that are always suspended (such as running top, tail), and it will automatically exit -v /usr/local/docker/redis.conf:/etc/redis/redis.conf //Mount the redis.conf configured on the host to the specified location in the container -v /usr/local/docker/data:/data //Mount the persistent data of redis to the host for data backup redis-server /etc/redis/redis.conf //Start redis according to the configuration of redis.conf –appendonly yes //Data persistence after redis starts
