Bitnami Secure Image for Redis®

Redis® is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

TL;DR

docker run --name redis -e ALLOW_EMPTY_PASSWORD=yes bitnami/redis:latest

Warning: These quick setups are only intended for development environments. You are encouraged to change the insecure default credentials and check out the available configuration options in the Configuration section for a more secure deployment.

Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise OS Photon Linux. Why choose BSI images?

• Hardened secure images of popular open source software with Near-Zero Vulnerabilities
• Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
• Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
• Software supply chain provenance attestation through in-toto
• First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in our public catalog here. Note: Some data is only available with commercial subscriptions to BSI.

If you are looking for our previous generation of images based on Debian Linux, please see the Bitnami Legacy registry.

How to deploy Redis(R) in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami Redis(R) Chart GitHub repository.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

Get this image

The recommended way to get the Bitnami Redis(R) Docker Image is to pull the prebuilt image from the Docker Hub Registry.

docker pull bitnami/redis:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

docker pull bitnami/redis:[TAG]

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build command. Remember to replace the APP, VERSION and OPERATING-SYSTEM path placeholders in the example command below with the correct values.

git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

Using docker-compose.yaml

Please be aware this file has not undergone internal testing. Consequently, we advise its use exclusively for development or testing purposes. For production-ready deployments, we highly recommend utilizing its associated Bitnami Helm chart.

Persisting your database

Redis(R) provides a different range of persistence options. This contanier uses AOF persistence by default but it is easy to overwrite that configuration in a docker-compose.yaml file with this entry command: /opt/bitnami/scripts/redis/run.sh --appendonly no. Alternatively, you may use the REDIS_AOF_ENABLED env variable as explained in Disabling AOF persistence.

If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a directory at the /bitnami path. If the mounted directory is empty, it will be initialized on the first run.

Note

As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Connecting to other containers

Using Docker container networking, a Redis(R) server running inside a container can easily be accessed by your application containers.

Containers attached to the same network can communicate with each other using the container name as the hostname.

Disabling Redis(R) commands

For security reasons, you may want to disable some commands. You can specify them by using the following environment variable on the first run:

• REDIS_DISABLE_COMMANDS: Comma-separated list of Redis(R) commands to disable. Defaults to empty.

Passing extra command-line flags to redis-server startup

Passing extra command-line flags to the redis service command is possible by adding them as arguments to run.sh script:

docker run --name redis -e ALLOW_EMPTY_PASSWORD=yes bitnami/redis:latest /opt/bitnami/scripts/redis/run.sh --maxmemory 100mb

Alternatively, modify the docker-compose.yml file present in this repository:

services:
  redis:
  ...
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
    command: /opt/bitnami/scripts/redis/run.sh --maxmemory 100mb
  ...

Refer to the Redis(R) documentation for the complete list of arguments.

Setting the server password on first run

Passing the REDIS_PASSWORD environment variable when running the image for the first time will set the Redis(R) server password to the value of REDIS_PASSWORD (or the content of the file specified in REDIS_PASSWORD_FILE).

NOTE: The at sign (@) is not supported for REDIS_PASSWORD.

Warning The Redis(R) database is always configured with remote access enabled. It's suggested that the REDIS_PASSWORD env variable is always specified to set a password. In case you want to access the database without a password set the environment variable ALLOW_EMPTY_PASSWORD=yes. This is recommended only for development.

Allowing empty passwords

By default the Redis(R) image expects all the available passwords to be set. In order to allow empty passwords, it is necessary to set the ALLOW_EMPTY_PASSWORD=yes env variable. This env variable is only recommended for testing or development purposes. We strongly recommend specifying the REDIS_PASSWORD for any other scenario.

Enabling/Setting multithreading

Redis 6.0 features a new multi-threading model. You can set both io-threads and io-threads-do-reads though the env vars REDIS_IO_THREADS and REDIS_IO_THREADS_DO_READS

Disabling AOF persistence

Redis(R) offers different options when it comes to persistence. By default, this image is set up to use the AOF (Append Only File) approach. Should you need to change this behaviour, setting the REDIS_AOF_ENABLED=no env variable will disable this feature.

Enabling Access Control List

Redis(R) offers ACL since 6.0 which allows certain connections to be limited in terms of the commands that can be executed and the keys that can be accessed. We strongly recommend enabling ACL in production by specifying the REDIS_ACLFILE.

docker run -name redis -e REDIS_ACLFILE=/opt/bitnami/redis/mounted-etc/users.acl -v /path/to/users.acl:/opt/bitnami/redis/mounted-etc/users.acl bitnami/redis:latest

Alternatively, modify the docker-compose.yml file present in this repository:

services:
  redis:
  ...
    environment:
      - REDIS_ACLFILE=/opt/bitnami/redis/mounted-etc/users.acl
    volumes:
      - /path/to/users.acl:/opt/bitnami/redis/mounted-etc/users.acl
  ...

Setting up replication

A replication cluster can easily be setup with the Bitnami Redis(R) Docker Image using the following environment variables:

• REDIS_REPLICATION_MODE: The replication mode. Possible values master/slave. No defaults.
• REDIS_REPLICA_IP: The replication announce ip. Defaults to $(get_machine_ip) which return the ip of the container.
• REDIS_REPLICA_PORT: The replication announce port. Defaults to REDIS_MASTER_PORT_NUMBER.
• REDIS_MASTER_HOST: Hostname/IP of replication master (replica node parameter). No defaults.
• REDIS_MASTER_PORT_NUMBER: Server port of the replication master (replica node parameter). Defaults to 6379.
• REDIS_MASTER_PASSWORD: Password to authenticate with the master (replica node parameter). No defaults. As an alternative, you can mount a file with the password and set the REDIS_MASTER_PASSWORD_FILE variable.

In a replication cluster you can have one master and zero or more replicas. When replication is enabled the master node is in read-write mode, while the replicas are in read-only mode. For best performance its advisable to limit the reads to the replicas.

Securing Redis(R) traffic

Starting with version 6, Redis(R) adds the support for SSL/TLS connections. Should you desire to enable this optional feature, you may use the following environment variables to configure the application:

• REDIS_TLS_ENABLED: Whether to enable TLS for traffic or not. Defaults to no.
• REDIS_TLS_PORT_NUMBER: Port used for TLS secure traffic. Defaults to 6379.
• REDIS_TLS_CERT_FILE: File containing the certificate file for the TLS traffic. No defaults.
• REDIS_TLS_KEY_FILE: File containing the key for certificate. No defaults.
• REDIS_TLS_CA_FILE: File containing the CA of the certificate (takes precedence over REDIS_TLS_CA_DIR). No defaults.
• REDIS_TLS_CA_DIR: Directory containing the CA certificates. No defaults.
• REDIS_TLS_DH_PARAMS_FILE: File containing DH params (in order to support DH based ciphers). No defaults.
• REDIS_TLS_AUTH_CLIENTS: Whether to require clients to authenticate or not. Defaults to yes.

When enabling TLS, conventional standard traffic is disabled by default. However this new feature is not mutually exclusive, which means it is possible to listen to both TLS and non-TLS connection simultaneously. To enable non-TLS traffic, set REDIS_TLS_PORT_NUMBER to another port different than 0.

Alternatively, you may also provide with this configuration in your custom configuration file.

Configuration file

The image looks for configurations in /opt/bitnami/redis/mounted-etc/redis.conf. You can overwrite the redis.conf file using your own custom configuration file.

docker run --name redis \
    -e ALLOW_EMPTY_PASSWORD=yes \
    -v /path/to/your_redis.conf:/opt/bitnami/redis/mounted-etc/redis.conf \
    -v /path/to/redis-data-persistence:/bitnami/redis/data \
    bitnami/redis:latest

Alternatively, modify the docker-compose.yml file present in this repository:

services:
  redis:
  ...
    volumes:
      - /path/to/your_redis.conf:/opt/bitnami/redis/mounted-etc/redis.conf
      - /path/to/redis-persistence:/bitnami/redis/data
  ...

Refer to the Redis(R) configuration manual for the complete list of configuration options.

Overriding configuration

Instead of providing a custom redis.conf, you may also choose to provide only settings you wish to override. The image will look for /opt/bitnami/redis/mounted-etc/overrides.conf. This will be ignored if custom redis.conf is provided.

docker run --name redis \
    -e ALLOW_EMPTY_PASSWORD=yes \
    -v /path/to/overrides.conf:/opt/bitnami/redis/mounted-etc/overrides.conf \
    bitnami/redis:latest

Alternatively, modify the docker-compose.yml file present in this repository:

services:
  redis:
  ...
    volumes:
      - /path/to/overrides.conf:/opt/bitnami/redis/mounted-etc/overrides.conf
  ...

Enable Redis(R) RDB persistence

When the value of REDIS_RDB_POLICY_DISABLED is no (default value) the Redis(R) default persistence strategy will be used. If you want to modify the default strategy, you can configure it through the REDIS_RDB_POLICY parameter.

FIPS configuration in Bitnami Secure Images

The Bitnami Redis® Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

• OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.

Logging

The Bitnami Redis(R) Docker image sends the container logs to the stdout. To view the logs:

docker logs redis

or using Docker Compose:

docker-compose logs redis

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

Notable Changes

5.0.8-debian-10-r24

• The recommended mount point to use a custom redis.conf changes from /opt/bitnami/redis/etc/ to /opt/bitnami/redis/mounted-etc/.

5.0.0-r0

• Starting with Redis(R) 5.0 the command REPLICAOF is available in favor of SLAVEOF. For backward compatibility with previous versions, slave replication mode is still supported. We encourage the use of the REPLICAOF command if you are using Redis(R) 5.0.

4.0.1-r24

• Decrease the size of the container. It is not necessary Node.js anymore. Redis(R) configuration moved to bash scripts in the rootfs/ folder.
• The recommended mount point to persist data changes to /bitnami/redis/data.
• The main redis.conf file is not persisted in a volume. The path is /opt/bitnami/redis/mounted-etc/redis.conf.
• Backwards compatibility is not guaranteed when data is persisted using docker-compose. You can use the workaround below to overcome it:

docker-compose down
## Locate your volume and modify the file tree
VOLUME=$(docker volume ls | grep "redis_data" | awk '{print $2}')
docker run --rm -i -v=${VOLUME}:/tmp/redis busybox find /tmp/redis/data -maxdepth 1 -exec mv {} /tmp/redis \;
docker run --rm -i -v=${VOLUME}:/tmp/redis busybox rm -rf /tmp/redis/{data,conf,.initialized}
## Change the mount point
sed -i -e 's#redis_data:/bitnami/redis#redis_data:/bitnami/redis/data#g' docker-compose.yml
## Pull the latest bitnami/redis image
docker pull bitnami/redis:latest
docker-compose up -d

4.0.1-r1

• The redis container has been migrated to a non-root container approach. Previously the container run as root user and the redis daemon was started as redis user. From now own, both the container and the redis daemon run as user 1001. As a consequence, the configuration files are writable by the user running the redis process.

3.2.0-r0

• All volumes have been merged at /bitnami/redis. Now you only need to mount a single volume at /bitnami/redis for persistence.
• The logs are always sent to the stdout and are no longer collected in the volume.
