How to wipe Heroku Redis?

Question

I have some information stored in my RedisToGo instance in Heroku and I want to wipe it so the Redis store is clean. Any idea how to do this?

Yes I want to clear the entire store. – kidcapital Feb 04 '12 at 03:11 — kidcapital, Feb 04 '12 at 03:11

You can do this with redis-cli.

RedisToGo gives you a url in the form:

redis://redistogo:d20739cffb0c0a6fff719acc2728c236@catfish.redistogo.com:9402

So this command will empty your db:

redis-cli -h catfish.redistogo.com -p 9402 -a d20739cffb0c0a6fff719acc2728c236 flushall

This gives me `(error) NOAUTH Authentication required.`. What is that about? – Apr 26 '15 at 04:04

@torazaburo That error occurs when you've entered bad credentials. – ty. Sep 02 '15 at 09:11
This no longer works. You get a NOAUTH error. There may be a missing step, but the steps above will just yield an error. – Jesse Farmer Sep 21 '18 at 04:18
@JesseFarmer I was just able to run this command successfully. Received "OK" response. You might want to double check your credentials. – ty. Sep 22 '18 at 08:11
@ty, it responds with OK, but it seems like it doesn't actually clear it. So far I wasn't able to find a way to clear rediscloud redis without accessing rails console. – AndreiMotinga Sep 29 '18 at 18:47
For anyone reading this answer, you can simply do `redis-cli -u redis://...` with the URL – Tallboy May 08 '22 at 02:54

You can install the heroku-redis-cli plugin

Installation

Requirements:

The heroku gem — gem install heroku
A local installation of redis (or at least the redis-cli utility) — apt-get install redis-server

To install:

heroku plugins:install https://github.com/rapportive-oss/heroku-redis-cli.git

Usage

heroku redis:info — get run-time statistics from your redis.
heroku redis:monitor — monitor commands being sent to your redis in real time.
heroku redis:cli — execute custom commands against redis.

Then you could simply do:

$ heroku redis:cli
$ flushall

Steps taken from readme file on the github repo: https://github.com/rapportive-oss/heroku-redis-cli

It is not an _Heroku_ command but an [heroku-redis-cli](https://github.com/rapportive-oss/heroku-redis-cli) plugin command. – esbanarango Apr 14 '14 at 20:02

It hasn't been updated for over 2 years and doesn't work – TJL Jun 26 '14 at 08:44

this was definitely an easier approach. worked for me. – amlutz160 Aug 27 '15 at 15:57

To wipe your redis on heroku there are a couple of ways. One of the simplest is probably connecting to the heroku console and clearing it from there. Commands are (for cedar stack):

heroku run console
REDIS.flushall

And that's it :-)

You can do this with the heroku console:

$ heroku redis:cli -a my_app --confirm my_app
$ FLUSHALL

You can destroy and recreate the entire Redis datastore for your app by doing:

heroku addons:remove redistogo
heroku addons:add redistogo

Is there a better way than dropping and re-adding the whole instance? – kidcapital Feb 04 '12 at 03:11

That's the easiest way. If you are using the environment variable then this should be a quick and easy change. – James Ward Feb 04 '12 at 03:23

In order to empty the store, you can run the flushall command: http://redis.io/commands/flushall

So, simply something like:

$redis.flushall

if you're doing it with Ruby or similar.

It depends on what you're using to be honest, if it's something like Rails you can run it via the Rails console (`heroku run console`) - however, it's very dependant on what tools you're using. – Neil Middleton Feb 05 '12 at 13:36

Get a python shell on heroku by doing the following CLI:

heroku run python

Then in that shell type

import os
import redis
redis_url = os.getenv('REDISTOGO_URL', 'redis://localhost')
r = redis.from_url(redis_url) 
r.flushdb()

This can be done in one convenient one-liner, even for non-ruby apps:

echo " FLUSHALL\r\n QUIT" | heroku redis:cli -a MY_APP --confirm MY_APP

Replace MY_APP with the name of your app.

Note: This assumes that you have Heroku CLI installed.

You can use this https://github.com/rapportive-oss/heroku-redis-cli to connect to the Redis instance you are using, Heroku update broke it some time ago but there is a fix https://github.com/johnbeynon/heroku-redis-cli. Then just do flushdb

If you're looking for a one-liner (and happen to be using Rails), you can do

heroku run rails runner 'REDIS.flushall'

rather than connecting first (with console) then manually entering the flushall command.
