How to successfully start redis in docker container and enter

The following are the steps to start redis in docker and enter:

First, you need to search for the image source related to redis through docker

docker search redis

Then We download the Redis image source through Docker

docker pull redis

If the version is not set here, the latest image source will be downloaded by default.

[root@localhost ~]# docker images
REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE
docker.io/tomcat          latest              aeea3708743f        9 days ago          529 MB
docker.io/rabbitmq        latest              2b5cda43d345        2 weeks ago         151 MB
docker.io/elasticsearch   7.6.0               5d2812e0e41c        2 weeks ago         790 MB
docker.io/redis           latest              44d36d2c2374        2 weeks ago         98.2 MB
docker.io/mysql           latest              791b6e40940c        2 weeks ago         465 MB
[root@localhost ~]#

Then create and start the Redis container

First start Docker

[root@localhost ~]# systemctl start docker

Start Redis in Docker

Here we do not set the alias of the container, -d Represents background startup.

[root@localhost ~]# docker run -d redis

You can also start Redis like this, where -p represents port mapping, mapping 6379 in the container to port 6379 in the machine running Docker, --name represents a custom container name

[root@localhost ~]# docker run -d -p 6379:6379   --name="myredis"  redis

[root@localhost ~]#

Enter the Redis terminal

docker exec ：在运行的容器中执行命令
# 语法
docker exec [OPTIONS] CONTAINER COMMAND [ARG...]
# OPTIONS说明：
-d :分离模式: 在后台运行
-i :即使没有附加也保持STDIN 打开
-t :分配一个伪终端

The container ID in Docker can be viewed with docker -ps

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

[root@localhost ~]#

redis-cli means running a redis client.

[root@localhost ~]# docker exec -it da45019bf760 redis-cli
127.0.0.1:6379> 
127.0.0.1:6379> set msg "Hello World Redis"
OK
127.0.0.1:6379> get msg
"Hello World Redis"
127.0.0.1:6379>
