How to resolve Docker could not connect to redis at 127.0.0.1:6379: connection refused error?
Redis is an open source (BSD licensed), in-memory data structure store used as a database, cache, message broker, and streaming engine.
Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.
It is one of the most popular Docker images.
The key-value store makes it possible to save data from Docker containers.
If you want to take advantage of this feature, you can connect Redis and Docker in the terminal.
Typically, above error occurs when Redis is disable.
- To start Redis server you can run the command below:
Redis install inside of Docker container
sudo service redis-server startTo restart Redis inside Docker run command:
sudo service redis-server restartRedis install outside of Docker(In OS such as Ubuntu)
systemctl restart redis-server
systemctl enable redis-serverTo check the status of Redis run command:
systemctl status redis-server2. You may need to daemonize the redis-server so that docker can connect to it:
/usr/local/bin/redis-server --daemonize yes
Then try again the command you performed, that gives you error.
