Docker Setup and Redis CLI

What you'll walk away with

Explain the core ideas behind Docker Setup and Redis CLI
Run the sample Redis command or code and verify its output
Apply the technique correctly to the Tutorial Platform and production scenarios

Build the mental model

Docker gives every learner a consistent environment. Bind only to `127.0.0.1`, use a named volume, and enable AOF persistence. One password is not a production security design, but it is safer than an unauthenticated local service and prepares you for ACL and TLS later.

Connect it to a real scenario

Run `redis:8.10-alpine` with AOF and a password. Pass `REDISCLI_AUTH` as command environment and verify readiness/version with `PING` and `INFO server`. Production credentials belong in a secret manager, not the repository or shell history.

Bind the port to localhost
Use a named volume and AOF
Verify readiness and version with PING/INFO

Try the working example

bash

docker volume create redis-data

docker run --name redis-tutorial \
  -p 127.0.0.1:6379:6379 \
  -v redis-data:/data \
  -d redis:8.10-alpine \
  redis-server --appendonly yes --requirepass learnredis

docker exec -e REDISCLI_AUTH=learnredis redis-tutorial redis-cli PING
docker exec -e REDISCLI_AUTH=learnredis redis-tutorial redis-cli INFO server

You should see

You see `PONG` and Redis 8.10.x server information.

5-minute try-it

Set `setup:test` to `ok`, stop/start the container, and verify that the volume and AOF preserve it.

One important caution

Never expose port 6379 to the public internet. A password alone does not replace network controls, ACLs, and TLS.

Easy traps

Never expose port 6379 to the public internet. A password alone does not replace network controls, ACLs, and TLS.
Validate sample commands on a local or test instance with recoverable data before applying them to production Redis.

Exercise

Set `setup:test` to `ok`, stop/start the container, and verify that the volume and AOF preserve it.

You'll know it worked when: You see `PONG` and Redis 8.10.x server information.
