To develop applications with the redis database we can use a Docker image.
The documentation is at https://hub.docker.com/_/redis/
Set up the redis container to be accessed via localhost on the local computer
Start the redis container
Start the redis container “detached” ( -d ) in the background and expose it through localhost:6379
- In the terminal execute
docker run -dit --name redis -p 127.0.0.1:6379:6379 redis
Check if the container running
- In the terminal execute
docker ps -a
Test the redis database
Start a shell session in the redis container to access the command line utility
- In the terminal execute
docker exec -it redis sh - At the # prompt start the redis cli
redis-cli - At the 127.0.0.1:6379> prompt test the connection
ping
The response should be “PONG” - Store a value
set cat 10
The response should be “OK” - Retrieve the value
get cat
The response should be “10” - Get the list of all keys
keys *
Set up redis to be used by other Docker containers
Create a network
Create a Docker network, so multiple containers can communicate with each other using it.
- In the terminal execute
docker network create redis
Start the redis container
Start the redis container “detached” ( -d ) in the background in the “redis” network to make it available for redis-cli.
- In the terminal execute
docker run --name redis --network redis -d redis
Start the redis command line utility
- In the terminal execute
docker run --name redis-cli -it --network redis --rm redis redis-cli -h redis
Using the redis command line utiliy
Store a value in the redis database
- In the terminal execute
set cat 10
Read a value from the redis database
- In the terminal execute
get cat
