Docker Redis Container

Step 1: Create a Docker Compose File

We'll create a Docker compose file that defines our Redis container.

redis-docker-compose.yml

services:
  redis-db:
    # Apple M1 Chip
    # platform: linux/amd64
    image: redis:7-alpine
    container_name: redis-db
    restart: always
    ports:
      - 6381:6379
    command: redis-server --save 60 1 --loglevel warning --requirepass Password1234
    volumes:     
      - redis_datadir:/data
    networks:
      - backend-network

networks:
  backend-network:
    driver: bridge

volumes:
  redis_datadir:

This file defines a single service, redis-db, which uses the official Redis 7-alpine image and maps port 6381 on your local machine to port 6379 in the container. The redis database authentication password set as Password1234.

Step 2: Start the Container

Now that we have our environment file and Docker compose file set up, it's time to start the container! Run the following command:

docker-compose -f redis-docker-compose.yml up -d

This will start the container in detached mode, meaning it will run in the background.

Step3: Test Redis Database Container

Once the container is running, we can test our database. Run the following commands:

Let us create some keys & values. 

Note: you should have redis-cli Client installed locally.

db_password=Password1234

redis-cli -h 127.0.0.1 -p 6381 -a ${db_password}

> set "Key1" "Value1"
> set "Key2" "Value2"
> SAVE
> exit

Test the database keys-

redis-cli -h 127.0.0.1 -p 6381 -a ${db_password}

> select 1
> keys *
> get "Key1"
> get "Key2"
> exit

Step 4: Stop the Container

Finally, we can stop the container by running the following command:

docker-compose -f redis-docker-compose.yml down

This will stop the container and remove it from memory.

That's it! We've successfully created and configured a Docker Redis container.
