Let's briefly look at the types of Redis commands that could be useful to us for TempMessenger:
- SET: Sets a given key to hold a given string. It also allows us to set an expiration in seconds or milliseconds.
- GET: Gets the value of the data stored with the given key.
- TTL: Gets the time-to-live for a given key in seconds.
- PTTL: Gets the time-to-live for a given key in milliseconds.
- KEYS: Returns a list of all keys in the data store.
To try them out, we can use redis-cli which is a program that ships with our Redis container. To access it, first log in to the container by executing the following in your terminal:
docker exec -it redis /bin/bash
Then access redis-cli in the same terminal window by simply running:
redis-cli
There ...
