@luxifer I'm curious when I run sudo dokku plugins-install and all my plugins install, why is that that the plugin always seemingly rebuilds the docker container? It seems other plugins don't do this. What part of the code causes this to occur?

this plugin suffers from the same issue as dokku buildstep: https://github.com/progrium/buildstep/pull/85/files
In some cases we want to use one redis instance by several apps. And we want to select different redis dbs for each of these apps.
Can we have an incremental REDIS_DATABASE variable for this?
I get this after installing this plugin and doing a rebuild of an app:
-----> Releasing node-js-app ... Usage: docker inspect CONTAINER|IMAGE [CONTAINER|IMAGE...] Return low-level information on a container/image -format="": Format the output using the given go template. -----> node-js-app linked to redis/node-js-app container
I'm using Docker 0.7.6
I'm getting the following error from the redis plugin, not entirely sure what's causing it:
ubuntu@domU-12-31-39-15-08-6C:/home/dokku$ dokku release flask-heroku-sample
Usage: docker inspect CONTAINER|IMAGE [CONTAINER|IMAGE...]
Return low-level information on a container/image
-format="": Format the output using the given go template.
export REDIS_IP=
export REDIS_URL=redis://:6379
-----> flask-heroku-sample linked to redis/flask-heroku-sample container
When testing the redis info:
ubuntu@domU-12-31-39-15-08-6C:~$ dokku redis:info flask-heroku-sample
Usage: docker inspect CONTAINER|IMAGE [CONTAINER|IMAGE...]
Return low-level information on a container/image
-format="": Format the output using the given go template.
Usage: docker port CONTAINER PRIVATE_PORT
Lookup the public-facing port which is NAT-ed to PRIVATE_PORT
P.S. I'm using the latest version of Dokku as per today (723cf1d43d commit)
It seems that after rebooting the Dokku server the redis image that comes up has lost all that data, is this expected?
See Kloadut/dokku-pg-plugin#12 (comment) for a comment on how dokku-pg-plugin addessed this.
dokku-redis uses always the same port and changes the IP in REDIS_URL. dokku-pg uses the same IP and changes the port in DATABASE_URL (see: https://github.com/Kloadut/dokku-pg-plugin/blob/master/commands#L167)
I notice in README.md that the deployment output shows a REDIS_IP env var. All I see from an installation as of 1 day ago is a REDIS_URL var. Would not IP and PORT env vars be useful?
ID=$(docker run -v $VOLUME -p 6379 -d $REDIS_IMAGE /bin/start_redis.sh)
for each project I have.
Is there a possibility to fix this problem?

root@precise64:~# dokku redis:create convos
mv: missing destination file operand after `/var/lib/docker/volumes/redis-convos'
Try `mv --help' for more information.
The current version sets a port for the redis-container via the -p switch.
This leads to docker binding that port to 0.0.0.0 /eth0.
For a development setup that seems convenient.
But not the best idea for more productive systems.
I tried to close down the port with iptables... but sunk some hours without success.
Therefore I recommend removing the -p from the commit script.
As linked containers get reported the docker IP anyway.
I have a "fixed" forked version here https://github.com/wesrc/dokku-redis-plugin/commit/101ce67006b1fc45ca924c807941c3dddac5a925 and can do a proper PR if wanted.
I created a container with the same name of the app. It worked. Then I tried delete it but I get this error:
76e6050a9e7f
Error response from daemon: Conflict, cannot delete 13d9c76a1d02 because the container 76e6050a9e7f is using it, use -f to force
FATA[0000] Error: failed to remove one or more images
I stopped the app and tried again and got the same error. Finally I did:
sudo docker rmi -f redis/demo
sudo dokku redis:delete demo
And all seems ok now. It could be a docker's problem.
On git push dokku dokku:master (I'm trying dokku out on another branch of my app, and renaming the remote ebranch to master), I'm getting the following output:
...
-----> Discovering process types

error: failed to push some refs to '<host>:<app>'
Any idea what's going wrong? Line 111 of commands is:
echo -e "$ENV_TEMP" | sed '/^$/d' | sort > $ENV_FILEI've already run dokku redis:create <app> too. I'm running this on a DigitalOcean dokku droplet (the 1GB instance, if it makes a difference).
Server is digital ocean ubuntu 13.04 64 bit.
heres the output when i try to manually run the image. dokku redis:create never starts it either.

let me know if you need any other info. I'm fairly new to docker so I'm not totally sure what is needed to debug this.
Heres the error i get when I run it without daemonizing it:

How do I unlink the redis container from my app? Because I can't remove the redis container.
dokku redis:delete www
b0b7a3a3028f
Error: Conflict, cannot delete 90bd00bd9e8f because the container b0b7a3a3028f is using it
2014/04/21 08:31:00 Error: failed to remove one or more images
REDIS_PORT and REDIS_HOST are wrong / not updated, while REDIS_URL is the correct info.
I'm using Digital Ocean's dokku image (0.2, I believe). It works great until I install dokku-redis like so:
ssh [email protected]
cd /var/lib/dokku/plugins
git clone https://github.com/luxifer/dokku-redis-plugin redis
dokku plugins-install
After this point, SSH connections to [email protected] are broken - no command, not git pushes are accepted.
Running dokku version doesn't given me anything.
I'm using virtual naming.
This can't be right.
dokku redis:create talkingdev

Hi @luxifer !
Thankyou so much for this plugin!
I just installed it into my new Dokku v0.3.19 app, and found I had to make a few changes to get it working with the new version of Docker that it ships with.
Is this plugin still maintained? I'd be happy to help out with it?
In the last few days this plugin has completely stopped working and my app is no longer able to connect to the redis store. I've recently updated my dokku install to v0.2.0 but I'm not sure if this issue occurred before or after.
I updated to master for this plugin today, reran dokku plugins-install, and rebooted a few times. The plugin shows up when I run dokku plugins and when I run dokku help but I don't see a redis process when I run docker ps. I do see the output from the redis pre-release hook when I deploy but my app is not able to connect to the redis store.
Running any dokku:redis command doesn't seem to do anything and produces no output. Here is the output from dokku redis:info www with DOKKU_TRACE set:
+ case "$1" in

I'see the specific redis var:
dokku config

REDIS_URL: redis://172.17.0.61:6379
But then, when I try to connect to the redis instance, I have the following error in the dokku logs:
> node app.js
Main stream starting
Error Error: Redis connection to redis://172.17.0.38:6379 failed - connect ENOENT
the redis instance seems to be running ( a ps confirm it), but there is nothing in redis log...Any help appreciate, thanks in advance
Hello. thank you for plugin.
Ubuntu 14.04
dokku v0.3.16
dokku-redis-plugin installed from readme instructions (no release versioning)
After first installation application linked with error:
bad URI(is not URI?): redis://174.17.0.44 174.17.0.44:6379 (URI::InvalidURIError)
dancing with a tambourine, restart app, stop/start redis container directly with docker – :link command get me right url redis://174.17.0.44:6379$ (Dollar dollar sign on the end? hmmm, strange... but rails parse url correctly and accept).
Day later, server was restarted – link broken again.
In this time only manual dokku config:set REDIS_URL allow me run my application linked with redis.
What i am doing wrong?
How can I import / export dumps?
Should I install redis-cli in my server to connect locally to the redis db?
Restarting my EC2 instance causes the app to retain its previous REDIS_URL variable and have the new one with the new IP.
Using latest dokku master branch as of yesterday and latest dokku-redis-plugin.
