Docker installs Redis
Method one, built with Dockerfile
Create Dockerfile
First, create a directory redis for later related things.
w3cschool@w3cschool:~$ mkdir -p ~/redis ~/redis/data
The data directory is mapped to the /data directory configured by the redis container as a storage directory for the persistence of redis data
Go to the redis directory you created and create Dockerfile

Create a mirror with Dockerfile and replace it with your own name
w3cschool@w3cschool:~/redis$ docker build -t redis:3.2 .
Once the creation is complete, we can find the image we just created in the local mirror list
w3cschool@w3cschool:~/redis$ docker images redis REPOSITORY TAG IMAGE ID CREATED SIZE redis 3.2 43c923d57784 2 weeks ago 193.9 MB
Method two, docker pull redis: 3.2
Find the redis image on Docker Hub
w3cschool@w3cschool:~/redis$ docker search redis NAME DESCRIPTION STARS OFFICIAL AUTOMATED redis Redis is an open source ... 2321 [OK] sameersbn/redis 32 [OK] torusware/speedus-redis Always updated official ... 29 [OK] bitnami/redis Bitnami Redis Docker Image 22 [OK] anapsix/redis 11MB Redis server image ... 6 [OK] webhippie/redis Docker images for redis 4 [OK] clue/redis-benchmark A minimal docker image t... 3 [OK] williamyeh/redis Redis image for Docker 3 [OK] unblibraries/redis Leverages phusion/baseim... 2 [OK] greytip/redis redis 3.0.3 1 [OK] servivum/redis Redis Docker Image 1 [OK] ...
Here we pull the official image with the label 3.2
w3cschool@w3cschool:~/redis$ docker pull redis:3.2
After waiting for the download to complete, we can find the REPOSITORY as redis with a label of 3.2 in the local mirror list.
Use redis mirroring
Run the container
w3cschool@w3cschool:~/redis$ docker run -p 6379:6379 -v $PWD/data:/data -d redis:3.2 redis-server --appendonly yes 43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330 w3cschool@w3cschool:~/redis$
Command Description:
-p 6379:6379: Map the container's port 6379 to the host's port 6379
-v $PWD/data:/data: Mount the data under the current directory in the host to the container's/data
redis-server --appendonly yes: Execute the redis-server startup command in the container and open the redis persistence configuration
View how the container started
w3cschool@w3cschool:~/redis$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 43f7a65ec7f8 redis:3.2 "docker-entrypoint.sh" ... 0.0.0.0:6379->6379/tcp agitated_cray
Connect, view the container
Use the redis image to execute the redis-cli command to connect to the newly launched container, and the host IP is 172.17.0.1
w3cschool@w3cschool:~/redis$ docker run -it redis:3.2 redis-cli -h 172.17.0.1 172.17.0.1:6379> info # Server redis_version:3.2.0 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:f449541256e7d446 redis_mode:standalone os:Linux 4.2.0-16-generic x86_64 arch_bits:64 multiplexing_api:epoll ...
