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?

Solution 1

You can do this with redis-cli.

RedisToGo gives you a url in the form:

redis://redistogo:[email protected]:9402

So this command will empty your db:

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

Solution 2

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

Solution 3

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 :-)

Solution 4

You can do this with the heroku console:

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

Solution 5

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?

[user7740901]

That's the easiest way. If you are using the environment variable then this should be a quick and easy change.

[Neil Middleton]

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.

[esbanarango]

It is not an Heroku command but an heroku-redis-cli plugin command.

[Lal Krishna]

It hasn't been updated for over 2 years and doesn't work

[Dom Barker]

only if you are running a ruby app

This gives me (error) NOAUTH Authentication required.. What is that about?

[amlutz160]

this was definitely an easier approach. worked for me.

@torazaburo That error occurs when you've entered bad credentials.

[Jesse Farmer]

This no longer works. You get a NOAUTH error. There may be a missing step, but the steps above will just yield an error.

[ty.]

@JesseFarmer I was just able to run this command successfully. Received "OK" response. You might want to double check your credentials.

[AndreiMotinga]

@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.

[nmu]

@Keyul just tried it and it seems to still be working.

[Radon Rosborough]

The plugin fails to install.

For anyone reading this answer, you can simply do redis-cli -u redis://... with the URL
