A connection to a Redis database is expected to run the application successfully. You need to download and run Redis DB on your local machine with default values localhost 6379.

You can also run the application via Docker.

docker-compose up --build -d

However, you need either to run it with Docker-compose ensuring that all containers are within a network or start application locally. In order to change environment two properties must be changed.

data-access.properties - property redis.host
logback.xml - configuration/appender/host element value

If application is to be run locally, both of above should be set to "localhost" If application is to be run in docker environment, both should be set to name of a redis container (by default "redis")

Docker automaticly translates container name to IP address, considering all containers are within same network. Try to avoid using any symbols in names of containers, because it may cause that URL exception to be thrown. Instead use letters only.

Operations on Redis DB

Use Redis CLI or attach to Redis docker image in order to manually operate on DB.

docker exec -it mockedservices_redis-server redis-cli

Attach to redis server image and open a redis client.

Useful redis-cli commands:

KEYS *

Show all keys in the db.

TYPE key

Show key type.

LRANGE key start stop

Display elements from the list.

LLEN key

Display list length.

SMEMBERS key

Display elements from hashSet. Logs can be found in lists with names logstash_yyyy-mm-dd.
