redis's Introduction

https://github.com/docker-library/redis

Maintained by: the Docker Community

This is the Git repo of the Docker "Official Image" for redis (not to be confused with any official redis image provided by redis upstream). See the Docker Hub page for the full readme on how to use this Docker image and for information regarding contributing and issues.

The full image description on Docker Hub is generated/maintained over in the docker-library/docs repository, specifically in the redis directory.

redis's Issues

libtasn1-6 and libidn11 security updates

The packages libtasn1-6 and libidn11 need to be updated in the current redis image on Docker Hub.

https://www.debian.org/security/2016/dsa-3568

For the stable distribution (jessie), this problem has been fixed in version 4.2-3+deb8u2.

commands are executed twice within docker-entrypoint.sh of version 3.2

exec gosu redis "$0" "$@"
this in docker-entrypoint.sh makes above commands executed twice. such as following when I set -ex in it:

root@ubuntu:~/Desktop/redis/3.2/alpine# docker run -it --rm redis-orig
+ [ redis-server != redis-server ]
+ [ redis-server != redis-server ]
+ id -u
+ [ redis-server = redis-server -a 0 = 0 ]
+ chown -R redis .
+ exec su-exec redis /usr/local/bin/docker-entrypoint.sh redis-server
+ [ redis-server != redis-server ]
+ [ redis-server != redis-server ]
+ id -u
+ [ redis-server = redis-server -a 100 = 0 ]
+ exec redis-server

What's the purpose of this? why not just
exec gosu redis "$@"

protected-mode breaks options (ports, volumes, etc) used with docker run.

I'm basically running into issue #60 in regards to options passed to docker run. Using this Dockerfile:

FROM redis:latest
COPY redis.conf /usr/local/etc/redis/redis.conf
CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]

And this command:

docker run myredis -p 6379:6379

I get this error message:

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 2
>>> 'protected-mode "no" "-p" "6379:6379"'
Bad directive or wrong number of arguments

Can't open the log file: No such file or directory

my OS is : ubuntu:15.10
my docker-compose.yml

version: '2'
services:

  redis:
    image: redis
    ports:
      - "6379:6379"
    volumes:
      -  ~/dbdata/redis_conf/redis.conf:/usr/local/etc/redis/redis.conf
    volumes_from:
      -  redisdata
    environment:

redisdata:
    image: redis
    volumes:
      - /home/keryhu/dbdata/redisdb:/data
    command: --break-redis

I copy the default redis.conf to the "~/dbdata/redis_conf/redis.conf" directory . And just modify the "requirepass" to "29c4181fb842b5f24a3103dbd2ba17accb1f7e3c8f19868955401ab921"

when i start the container ,i met an error -

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 103
>>> 'logfile /var/log/redis/redis-server.log'
Can't open the log file: No such file or directory

Can help me ?

No dockerfile is present for building redis container on Ubuntu for power8 architecture

I have ported Redis to power8 architecture (ppc64le) and have also dockerized it on Ubuntu. I want to contribute docker files back to Redis community.

I would like to know more about,

What is the correct way/procedure to commit/submit dockerfile to repository?
Is there any preference about naming convention of docker files and their place in repository?

Making the discontinued v2.8 alive again

Hi,

I've found that you have discontinued 2.8 and removed it from Dockerhub.

I was actually using the version and still need it, because Amazon's AWS Elasticache still only supports version 2.6 towards 2.8.
http://docs.aws.amazon.com/ja_jp/AmazonElastiCache/latest/UserGuide/SelectEngine.html

Since they don't support 3x, I still need Redis 2x on Docker to synchronize the capability and functionality between Elasticache and my local testing/development facility built on Docker.

Is it possible to turn 2.x back to alive?

Thanks

Getting a REDIS_PORT env set to tcp://IP:6379 instead of 6379

Hi,

When linking this container with php, I'm getting a REDIS_PORT env being set to tcp://IP:6379 instead of 6379, which just gives me error after error about tcp://172.17.0.7:tcp://172.17.0.7:6379 not existing, which of course it doesn't. Any way we can actually make it a port by default?

At the moment I have to run my containers with -e "REDIS_PORT=6379".

Cheers

Slim number of redis versions

We support too many versions. After the rebuilding, we should cut out most of them, but make sure to keep 2.8.6 (for AWS parity). Maybe a determine an end-of-life cycle for all Docker maintained Official Images (individually or collectively)?

What am I doing wrong?

32 bit?

I was wondering if it would possible to get a 32bit image. I have been trying to get my own built, but I can't seem to get it working.

I added libc6-dev-i386 to $buildDeps and removed --no-install-recommends. I then changed make -C /usr/src/redis to make 32bit -C /usr/src/redis. Everything builds fine.

Go to run it. docker run redis. Get exec: "/entrypoint.sh": permission denied. Add RUN chmod +x entrypoint.sh

Now when I try and run it, I get error: exec failed: no such file or directory.

ls -la /usr/local/bin gives me:

Any idea what's going on? Am I taking the right approach?

Dockerfile: https://gist.github.com/b758f19378c719e3d42e

Entrypoint is the same

8mb /core file

Is there a reason that there is what looks like a 8mb core dump file in the redis:3.2.3-alpine docker image? It does look like it compresses down to 28kb so it probably doesn't take up much space, but it still seems odd to just be hanging around.

It looks like it has been hanging around since June 23rd, 2016:

Access: 2016-06-23 21:59:02.000000000 +0000
Modify: 2016-06-23 21:59:02.000000000 +0000

It does not appear to be on the redis:3.0.7-alpine image.

start with persistent storage (/data/dump.rdb) volume-shared-filesystems

I'm trying to "start with persistent storage" Redis docker using Docker run reference, however, inside of docker container I see /data/dump.rdb file, yet on host I do not:

alexus@mbp:~ $ docker run --name redis --volume=data:/data/:rw -p 6379:6379 -d redis
720d5faa3c90ae73bf0add2013fe074dd4bc14a6c30b6c593fa88646371efd4d
alexus@mbp:~ $ ls data/
alexus@mbp:~ $

please advise)

Permissions on mounted /data volume not correct

I'm running this instance with the /data directory mounted to the host machine with

-v /data/redis:/data

For some reason the permissions on the volume are not getting set properly despite the chown call in the Dockerfile, and therefore Redis pukes when trying to persist the DB.

Any ideas?

Move docker-entrypoint.sh to the root directory

I'm not sure what the convention is here but it would seem like the entrypoint script should live in the root directory judging from other official images.

xxxxxxxx_elasticsearch_1   /docker-entrypoint.sh elas
xxxxxxxx_neo4j_1           /docker-entrypoint.sh neo4j
xxxxxxxx_percona_1         /docker-entrypoint.sh mysqld
xxxxxxxx_redis_1           docker-entrypoint.sh redis

State that protected mode is disabled

README here and at https://hub.docker.com/_/redis/ should say that protected mode is disabled.

#74 (comment)

WARNING overcommit_memory is set to 0

When I start container, I see this in logs:

WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

I want data to be persistent. Should I worry about it?

Establish provenance of gosu

In the Redis dockerfile, the checksum for the redis download is tested, but the gosu one isn't. I release this is code under your control, but it's not completely infeasible that someone could hack the repository.

I know this is a pain, especially if you change the gosu code, but I think it is important for official images.

* FATAL CONFIG FILE ERROR * passing as parameter redis.conf file

I am trying to create a Redis cluster node passing as parameter my own redis.conf file with the following configuration:

port 7000
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes

I am running the following command to create the cluster node, which seems to be correct according with the documentation:

docker run -v redis.conf:/usr/local/etc/redis/redis.conf --name node redis redis-server /usr/local/etc/redis/redis.conf

But I am getting the following error:

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 2
>>> 'protected-mode "no" "/usr/local/etc/redis/redis.conf"'
Bad directive or wrong number of arguments

If I create my own Dockerfile to add the configuration file inside, it works perfect. But this is not the solution that I pursuit due I need to create nodes with different port numbers.

If I remove the port number from my configuration file, then I create my custom image named "redis-cluster-node" and finally I run the following command to pass the port as parameter:

docker run --name node redis-cluster-node -p 7000

I get the following error:

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 2
>>> 'protected-mode "no" "-p" "7000"'
Bad directive or wrong number of arguments

My configuration file works fine with the original project when I create a cluster node, so I presume the problem is related with the docker image itself or maybe I am missing something.

Can you help me with this? Thanks in advance! 😃

gpg recv-keys not working

In all your Dockerfiles, the command "gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4" fails for me with a timeout. This is because the default port used by gpg is blocked on my corporate firewall and instead I have to use port 80.

So the correct command which should work for everybody should be:
gpg --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-keys 0xB42F6819007F00F88E364FD4036A9C25BF357DD4

Please note the two changes:

the keyserver address has been fully qualified with protocol and port, and
the key ID has been preceeded with "0x" which is the correct syntax fot the keyserver being used.

Build issue with Docker 1.7.0

After a fresh Docker 1.7.0 update I'm unable to build that container again.
Downgrading to 1.6.2 fix the issue.

3.2 Dockerfile breaks compatibility for custom config path

As a user of an older version of the docker container I'm used to have my configuration file in /data/redis.conf and expect to be able to continue using this behavior

Steps to reproduce

# docker run --rm -ti -v /data/redis:/data redis redis-server /data/redis.conf

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 2
>>> 'protected-mode "no" "/data/redis.conf"'
Bad directive or wrong number of arguments

Observed result

Parameter --protected-mode no is injected before the configuration file name and the container fails with above mentioned error

Expected result

Redis starts using /data/redis.conf as its config file

create a redis cluster in a single container, client connect failed due to container ip

i create a redis cluster with all nodes in one docker container, and expose all ports.
If i connect the cluster in the containers host, it can connect the container successful,
if i run: redis-cli -c -h [container host ip] -p 7000 on other host, I find that it try to connect the real ip of cluster node, that is the docker container's private ip(not the container host ip). so it fail always.

I'm not sure if this would helpful.

Redis 3.0.0 is out

See https://groups.google.com/forum/#!msg/redis-db/dO0bFyD_THQ/Uoo2GjIx6qgJ

I imagine this can essentially be added by copying the 2.8 content and changing the lines that have to do with 2.8 to 3.0?

WARNING you have Transparent Huge Pages (THP) support enabled

When Redis starts I'm seeing the following two warnings, Is this something to be concerned about or something that should be corrected in the docker-library redis:2.8 image?

Server started, Redis version 2.8.23

WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

dump.rdb getting set to read-only

I seem to be having a recurring issue. Every few days my redis container starts throwing errors such as:

1:M 04 Feb 17:45:03.166 # Background saving error
1:M 04 Feb 17:45:09.085 * 1 changes in 3600 seconds. Saving...
1:M 04 Feb 17:45:09.085 * Background saving started by pid 1031
1031:C 04 Feb 17:45:09.086 # Failed opening .rdb for saving: Permission denied

Which is causing my clients to fail writes.

I have docker exec'd into the container and verified that the /data/dump.rdb file is read-only. I imagine this is causing those errors. I can't figure out why that file would be read-only.

I am running the container with no options other than container names and ports. I'm not mounting in any volumes or anything of the sort.

Anyone have any ideas?

Doesn't save on SIGTERM

According to http://redis.io/topics/signals Redis is supposed to do a save on SIGTERM:

If Redis is configured to persist on disk using RDB files, a synchronous (blocking) save is performed. Since the save is performed in a synchronous way no additional memory is used.

According to http://docs.docker.com/reference/commandline/cli/#stop Docker sends a SIGTERM followed by a SIGKILL after a period (10 second default).

The main process inside the container will receive SIGTERM, and after a grace period, SIGKILL

It seems to receive the SIGTERM and gracefully shutdown but it does so without a save.
Subsequent start of the container doesn't have the data.

Image is HUGE

This image comes in at 812MB for me, which is much much much larger than I would expect for a redis image.

Valgrind seems to be the real culprit here. Is this a build dep for redis?
Adjusting the Dockerfile for optimizing size yields a 364.6 MB image:

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
RUN groupadd -r redis && useradd -r -g redis redis

Any clue as to whats happening?

chown operation not permitted when running container with --user=xxxx

I am using Vagrant's docker provisioner to install a docker host on a development VM and then run the redis:3.2 image in a container.

When I was using vagrant 1.7.2 (which installed docker 1.9.1) and VirtualBox 4.3.x the following vagrantfile snippet worked:

    # according to the docker docs, this command is idempotent as long as the same driver is used
    dbs.vm.provision 'shell', inline: "docker volume create --driver local --name datastore"

    dbs.vm.provision "docker" do |docker|
      # run the redis container (Vagrant daemonizes and restarts by default, no need to add flags here)
      # use the datastore volume for storage and run as linux user id 1000 (works around filesystem permissions issues)
      docker.run "redis",
        image: "redis:3.2",
        args: "-v 'datastore:/data' -p '6379:6379' -u 1000",
        cmd: "redis-server --appendonly yes"
    end

Now that I have updated to VirtualBox 5.0.20, Vagrant 1.8.1 (which installs docker 1.11.2), I get the following error:

==> dbs: datastore
==> dbs: Running provisioner: docker...
==> dbs: Starting Docker containers...
==> dbs: -- Container: redis
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

          rm -f /var/lib/vagrant/cids/b840fc02d524045429941cc15f59e41cb7be6c52

I note that the docker-entrypoint.sh for 3.2 is what runs the chown command. Can you think of any reason why the container no longer has permissions to chown /var/lib/docker/volumes/datastore/_data just because I updated to a newer Vagrant/Docker combination?

EDIT: I have also tried to run these containers with --privileged=true but I get the same error.

Connecting through localhost...

I am on osx and I'm trying to use this container by doing:

$ docker run --name redis -p 6379:6379 -d redis
$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

Based on this it seems like the container is running properly, and the key being: 0.0.0.0:6379->6379/tcp

However when I attempt to connect to the server via node_redis with code like this:

var redis = require('redis');
var client = redis.createClient(); // localhost:6379
client.on('error', function (err) {
    console.log('Redis Error:', err); // errors here
});

I get this error:

Redis Error: { [Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 6379 }

I've tried using some other clients, and they all do the same thing. Furthermore, trying to use the linking suggested in the documentation here, this same code when run in that container is also having this error.

What am I missing?

Shouldn't we set overcommit_memory=1?

Guys,

There are some official recommended settings here http://redis.io/topics/admin

One should be
RUN sysctl vm.overcommit_memory=1

What do you think?

Thanks

Does redis:latest (3.2.3) start in protected mode? Does passing ` --protected-mode no` work?

There is SO question http://stackoverflow.com/questions/39424559/check-connect-to-redis-running-within-docker-from-javaspring-boot-or-node-js

I expected that docker run -p 6379:6379 redis would give ready to use redis instance.

If it is decided not to keep protected mode, README here should have tips how to disable it.

Cluster mode?

Redis has settings for cluster mode.

How can I use it with this image?

HTTP code 400 on docker pull redis

I'm receiving an error with HTTP code 400 when trying to pull the latest redis image. These errors started around 2015/09/11 13:02:10 UTC. The issue seems to be with image tags > 2.8.21 as I'm able to pull and run tag 2.8.21 with no problem.

See below for the output:

Docker Hub doesn't have the new versions

2.8.14 - 2.8.17

Disable Transparent Huge Pages (THP) in docker machine

We probably need to disable Transparent Huge Pages (THP) inside the docker machine this might cause latency and memory usage issues with Redis.
To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled'

make install does not install redis-sentinel

Even though sentinel is essentially redis-server --sentinel, it would be good to be able to use redis-sentinal directly as is the convention in the redis community.

dockerfile/redis does this here: https://github.com/dockerfile/redis/blob/master/Dockerfile#L18

Please provide a 2.8.6 tag

2.8.6 is a little outdated, yes, but it's the latest version provided by AWS ElastiCache, so it would be helpful to have available for the sake of development/production parity.

P.S. I tried to make a PR out of this, but I can't seem to propose that you pull something into a new branch. Here's the relevant commit, though: 1d4d9e7

Thanks!

Redis container not starting

Getting "Creating Server TCP listening socket *:6379: unable to bind socket"
OS UnRAID 6.1.9 , Docker ver1.7.1

Set password and other options via ENV variable

It would be awesome if it would be possible to set the Password via an ENV variable. Is this planned any time soon or maybe even already possible?

Of course it would even more awesome when we could set other parameters as well 👍

custom redis.conf

The current idea for dealing with custom config is having the user make the following:

FROM redis
ADD redis.conf /data/
CMD [ "redis-server", "/data/redis.conf" ]

If we are encouraging the user to put the config into the /data volume, it would be better to make an entrypoint that checks for the custom conf file and puts in into the launch args. That way a user only has to ADD the file to a data container or put it in a bind mounted volume and run it with docker run --volumes-from datacontainer --name myredis redis. There would be no need for the user to have a Dockerfile for the redis container.

Tag 3.2 doesn't run with `--protected-mode no` with persistent storage or other args

Expected behavior:
Redis runs in docker container in unprotected mode.

Actual behavior:
Starting the container with redis-server --appendonly yes (or probably any other explicit arguments) causes redis to start in protected mode.

Details:
When running the redis docker image from tag 3.2 with docker run --name token-redis -p ${MY_PORT}:6379 -d redis:3.2 redis-server --appendonly yes the following error is produced.

Error: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside. channel: [id: 0x8d7ec4dc, /192.168.99.1:52640 => /192.168.99.101:6379] data: null

The explicit arguments override the CMD in the dockerfile which disables protected mode.

Suggestion:
If the intention is to always disable protected mode (makes sense) then move --protected-mode no to docker-entrypoint.sh so that it always runs, even with over-ridden CMD.
If the intention is to allow the container to be run with protected mode, then update the docs on docker hub (specifically under the header start with persistent storage) to indicate that --protected-mode no also needs to be provided.

Use --userns-remap ?

Hello,

I was wondering if there is any reason to not use --userns-remap available since docker 1.10 ?
