And, install a version of reids, I have installed the official version.

1 2	$ docker pull redis:latest # you can install the latest version of redis $ docker images # you can use this command to view how many images have been installed on docker

And then, create a redis image on docker.

$ docker run -itd --name redis-test -p 6379:6379 redis
$ docker ps   # you can view redis version by this command
CONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS          PORTS                                       NAMES
90f9bfe40ae4   redis     "docker-entrypoint.s…"   42 minutes ago   Up 42 minutes   0.0.0.0:6379->6379/tcp, :::6379->6379/tcp   redis-test

Finally, you can run redis on docker like this:

1	$ sudo docker run -it --name redis-test -d redis bash

Or like this:

1
2
3

$ sudo docker exec/run -it redis-test bash
# you can also use CONTAINER ID instead of NAMES
$ sudo docker exec/run -it 90f9bfe40ae4 bash

When you at this step, it’s not means you are started redis successfully, you need run it on a remote host:

$ redis -h [ip address or domain address] -p port 
# for example
$ redis -h 127.0.0.1 -p 6379
127.0.0.1:6379>   # when you see this line, it's means successful.
