How to wipe Heroku Redis?
HerokuRedisHeroku Problem Overview
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?
Heroku Solutions
Solution 1 - Heroku
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 - Heroku
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 - Heroku
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 - Heroku
You can do this with the heroku console:
$ heroku redis:cli -a my_app --confirm my_app
$ FLUSHALL
Solution 5 - Heroku
You can destroy and recreate the entire Redis datastore for your app by doing:
heroku addons:remove redistogo
heroku addons:add redistogo
Solution 6 - Heroku
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.
Solution 7 - Heroku
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()
Solution 8 - Heroku
heroku run rails c
$redis.flushall
Solution 9 - Heroku
I'm using Ruby on Rails on Heroku and tried this, it worked (After heroku run rails console)
> $redis = Redis.new url: ENV['REDISCLOUD_URL']
> $redis.flushall
=> "OK"
Solution 10 - Heroku
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
Solution 11 - Heroku
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.
Solution 12 - Heroku
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.
