Rekor server - redis not found

[iamulya]

While trying to run rekor server using the following command: $HOME/go/bin/rekor-server serve --trillian_log_server.port=8091 --enable_retrieve_api=false, I ran into the following issue regarding redis

PANIC   api/api.go:140  failure connecting to redis instance: dial tcp 127.0.0.1:6379: connect: connection refused

Do we have to start a redis instance ourselves?
