1. Copy server certificate into tls/server.crt.
2. Copy server private key into tls/server.key.
3. Copy the client's CA certificate into tls/ca.crt if self-signed CA.
4. Update requirepass with your own password in both config/redis.conf and config/redis-docker.conf if you wish to.

If you have redis installed, you can just start redis with this command.

$ redis-server config/redis.conf

To run redis in docker container, first build the docker image with this command.

$ docker build -t redis-custom .

When the build is finished, start the container with this command.

$ docker run -d --rm -p 8080:6379 --name redis redis-custom

You can use my redis-client tool to test connectivity.
