Configuration

Redis Commander can be configured by configuration files, environment variables or using command line parameters. The different types of config values overwrite each other, only the last (most important) value is used.

For configuration files the node-config module (https://github.com/lorenwest/node-config) is used, with default to json syntax.

The order of precedence for all configuration values (from least to most important) is:

  • Configuration files

    default.json - this file contains all default values and SHOULD NOT be changed

    local.json - optional file, all local overwrites for values inside default.json should be placed here as well as a list of redis connections to use at startup

    local-<NODE_ENV>.json - Do not add anything else than connections to this file! Redis Commander will overwrite this whenever a connection is added or removed via user interface. Inside docker container this file is used to store all connections parsed from REDIS_HOSTS env var. This file overwrites all connections defined inside local.json

    There are some more possible files available to use - please check the node-config Wiki for an complete list of all possible file names (https://github.com/lorenwest/node-config/wiki/Configuration-Files)

  • Environment variables - the full list of env vars possible (except the docker specific ones) can be get from the file config/custom-environment-variables.json together with their mapping to the respective configuration key.

  • Command line parameters - Overwrites everything

Environment Variables

These environment variables can be used starting Redis Commander as normal application or inside docker container (defined inside file config/custom-environment-variables.json):

HTTP_USER
HTTP_PASSWORD
HTTP_PASSWORD_HASH
ADDRESS
PORT
URL_PREFIX
ROOT_PATTERN
NOSAVE
NO_LOG_DATA
FOLDING_CHAR
USE_SCAN
SCAN_COUNT
FLUSH_ON_IMPORT
REDIS_CONNECTION_NAME
REDIS_LABEL

Docker

All environment variables listed at "Environment Variables" can be used running image with Docker. The following additional environment variables are available too (defined inside docker startup script):

REDIS_PORT
REDIS_HOST
REDIS_SOCKET
REDIS_PASSWORD
REDIS_DB
REDIS_HOSTS
SENTINEL_PORT
SENTINEL_HOST
K8S_SIGTERM

The K8S_SIGTERM variable (default "0") can be set to "1" to work around kubernetes specificas to allow pod replacement with zero downtime. More information on how kubernetes handles termination of old pods and the setup of new ones can be found within the thread [https://github.com/kubernetes/contrib/issues/1140#issuecomment-290836405]

Hosts can be optionally specified with a comma separated string by setting the REDIS_HOSTS environment variable.

After running the container, redis-commander will be available at localhost:8081.

Valid host strings

the REDIS_HOSTS environment variable is a comma separated list of host definitions, where each host should follow one of these templates:

hostname

label:hostname

label:hostname:port

label:hostname:port:dbIndex

label:hostname:port:dbIndex:password

With docker-compose

version: '3'
services:
  redis:
    container_name: redis
    hostname: redis
    image: redis
 
  redis-commander:
    container_name: redis-commander
    hostname: redis-commander
    image: rediscommander/redis-commander:latest
    restart: always
    environment:
    - REDIS_HOSTS=local:redis:6379
    ports:
    - "8081:8081"

Without docker-compose

Simplest

If you're running redis on localhost:6379, this is all you need to get started.

docker run --rm --name redis-commander -d \
  -p 8081:8081 \
  rediscommander/redis-commander:latest

Specify single host

docker run --rm --name redis-commander -d \
  --env REDIS_HOSTS=10.10.20.30 \
  -p 8081:8081 \
  rediscommander/redis-commander:latest

Specify multiple hosts with labels

docker run --rm --name redis-commander -d \
  --env REDIS_HOSTS=local:localhost:6379,myredis:10.10.20.30 \
  -p 8081:8081 \
  rediscommander/redis-commander:latest

Kubernetes

An example deployment can be found at k8s/redis-commander/deployment.yaml.

If you already have a cluster running with redis in the default namespace, deploy redis-commander with kubectl apply -f k8s/redis-commander. If you don't have redis running yet, you can deploy a simple pod with kubectl apply -f k8s/redis.

Alternatively, you can add a container to a deployment's spec like this:

containers:
- name: redis-commander
  image: rediscommander/redis-commander
  env:
  - name: REDIS_HOSTS
    value: instance1:redis:6379
  ports:
  - name: redis-commander
    containerPort: 8081

OpenShift V3

To use the stock Node.js image builder do the following.

  1. Open Catalog and select the Node.js template
  2. Specify the name of the application and the URL to the redis-command github repository
  3. Click the advanced options link
  4. (optional) specify the hostname for the route - if one is not specified it will be generated
  5. In the Deployment Configuration section
    • Add REDIS_HOST environment variable whose value is the name of the redis service - e.g., redis
    • Add REDIS_PORT environment variable whose value is the port exposed of the redis service - e.g., 6379
    • Add value from secret generated by the redis template:
      • name: REDIS_PASSWORD
      • resource: redis
      • key: database-password
  6. (optional) specify a label such as appl=redis-commander-dev1
    • this label will be applied on all objects created allowing for easy deletion later via:
    oc delete all --selector appl=redis-commander-dev1

Build images based on this one

To use this images as a base image for other images you need to call "apk update" inside your Dockerfile before adding other apk packages with "apk add foo". Afterwards, to reduce your image size, you may remove all temporary apk configs too again as this Dockerfile does.
