Raketask for connecting to Redis on Heroku

Assuming redis-cli is installed on your computer and you're using OpenRedis. If not, replace OPENREDIS_URL with the correct Heroku config variable that contains a Redis connection string.

desc 'Connect to Redis (production)'
task :redis do
 redis_uri = `heroku config:get OPENREDIS_URL`
 pattern = /redis:\/\/:(\S+)@(\S+):(\d+)/
 redis_uri[pattern]
 exec "redis-cli -a #{1ドル} -h #{2ドル} -p #{3ドル}"
end

Execute by running rake redis

The regex pattern will capture the password, the host and the port into 1ドル, 2ドル and 3ドル respectively. exec will replace the currently running process with that of the command being executed, in this case redis-cli.

Perhaps a bit Perl-ish code, but it gets the job done. :)

Update: OpenRedis is using a proxy these days. For details, see http://gist.io/4198977
