Redis

• Fastest data platform.
• Open source, advanced key-value store.

• Provides cloud and on-premise solutions for:

  • Caching.
  • Vector search.
  • NoSQL databases.

  

• Seamlessly fit into any tech stack.
• “Protected mode” is turned off by default.
  • For ease of use in dev env.
  • If you expose the port outside of your host, it will be open without a password to anyone.
  • Supplying a config file, in that file set a password.
  • Learn more:
    • Redis documentation on security⁠.
    • Protected mode⁠.
    • A few things about Redis security by antirez⁠.
• We use Redis Insight as our dashboard.

• I use bitnami since it is well documented.

  • It uses AOF persistence.
  • NOTE: The @ is not supported for REDIS_PASSWORD.

  • Note that Redis’s default port number is 6379, but we can change it:

    docker run --name redis -e REDIS_PORT_NUMBER=7000 -p 7000:7000 bitnami/redis:latest
    

• In the healthcheck command for the Redis we are passing the password and the port that your Redis instance is using within the container:
  1. To learn more about why our healthcheck command is using grep PONG read this Stackoverflow Q&A.
  2. We need to prevent docker compose from parsing environment variables inside our test command, thus the reason we used $$ (ref).

Redis Insight

• An ideal tool for developers who build with any Redis deployments to optimize their development process.
• Let you visually browse and interact with data, take advantage of the advanced command line interface and diagnostic tools.
• Log levels: error, warn, info, http, verbose, debug, silly.
