This simple container image bundles together the latest stable releases of Redis and select Redis modules from Redis Labs. This image is based on the official image of Redis from Docker. By default, the container starts with Redis' default configuration and all included modules loaded.
- RediSearch: a full-featured search engine
- RedisGraph: a graph database
- RedisTimeSeries: a timeseries database
- RedisAI: a tensor and deep learning model server
- RedisJSON: a native JSON data type
- RedisBloom: native Bloom and Cuckoo Filter data types
- RedisGears: a dynamic execution framework
The latest redismod:preview Docker image holds RedisJSON 2.0 and RediSearch 2.2 Private Preview Release. This Private Preview Releases delivers real-time document capabilities with active-active support. The ability to index, query, and use full-text search on JSON documents using RediSearch is the coolest new feature of this release. Try it out today -
docker run -p 6379:6379 redislabs/redismod:preview
Refer to the link provided in the References section for further details.
To use RedisMod on a local Mac, the first step is to install Docker for your operating system. Run the docker version command in a terminal window to make sure that docker is installed correctly.
It should display Docker Engine Server and Client version successfully.
Let us test drive RediSearch modules as discussed below in detail.
We are now ready to insert some data. This example uses movies data stored as Redis Hashes, so let’s insert a couple of movies:
Your Redis database now contains two Hashes. It is simple to retrieve information using the HMGET command, if you know the key of the movies (movies:11002):
To be able to query the hashes on the field for title, say, or genre, you must first create an index. To create an index, you must define a schema to list the fields and their types that are indexed, and that you can use in your queries.
Use the FT.CREATE command to create an index, as shown here:
You can now use the FT.SEARCH to search your database, for example, to search all movies sorted by release year:
