Rediseen

"Latest Release" action travis codecov License Go Report Card Docker Pull

Start a REST-like API service for your Redis database, without writing a single line of code.

  • Allows clients to query records in Redis database via HTTP conveniently
  • Allows you to specify which logical DB(s) to expose, and what key patterns to expose
  • Expose results of Redis INFO command in a nice format, so you can use Rediseen as a connector between your Redis DB and monitoring dashboard as well.
  • Supports API Key authentication

(Inspired by sandman2; Built on shoulder of go-redis/redis ; CLI implemented with Cobra)

Quick Start

Let's assume that your Redis database URI is redis://:@localhost:6379, and you want to expose keys with prefix key: in logical database 0.

Quick Start with go get

If you have Go (1.11+) installed, you can install Rediseen easily by running

go get github.com/xd-deng/rediseen

If your GOPATH is added to PATH, you should be able to run command rediseen now.

# Configuration
export REDISEEN_REDIS_URI="redis://:@localhost:6379"
export REDISEEN_DB_EXPOSED=0
export REDISEEN_KEY_PATTERN_EXPOSED="^key:([0-9a-z]+)"

# Start the service
rediseen start

Now you should be able to query against your Redis database, like http://localhost:8000/0, http://localhost:8000/0/key:1, http://localhost:8000/info or http://localhost:8000/info/server (say you have keys key:1 (string) and key:2 (hash) set in your logical DB 0). Sample responses follow below.

GET /0

{
    "count": 2,
    "total": 2,
    "keys": [
        {
            "key": "key:1",
            "type": "string"
        },
        {
            "key": "key:2",
            "type": "hash"
        }
    ]
}
GET /0/key:1

{
    "type": "string",
    "value": "rediseen"
}
GET /info

{
    Server: {
        redis_version: "5.0.6",
        ...
    },
    Clients: {
        ...
    },
    ...
}
GET /info/server

{
    Server: {
        redis_version: "5.0.6",
        ...
    }
}

For more details, please refer to the rest of the documentation.

Quick Start with Homebrew

# Install using Homebrew
brew install XD-DENG/rediseen/rediseen

Then you can configure and start the service as described above.

Quick Start with Docker

docker run \
    -e REDISEEN_REDIS_URI="redis://:@[YOUR REDIS HOST]:6379" \
    -e REDISEEN_DB_EXPOSED=0 \
    -e REDISEEN_KEY_PATTERN_EXPOSED="^key:([0-9a-z]+)" \
    -p 8000:8000 \
    xddeng/rediseen:latest

Please note:

  • REDISEEN_REDIS_URI above should be a specific host address. If you are running Redis database using Docker too, you can consider using Docker's link or network feature to ensure connectivity between Rediseen and your Redis database (refer to the complete example below).
  • You can choose the image tag among:
    • latest (the latest release version)
    • nightly (the latest code in master branch)
    • unstable (latest dev branch)
    • release tags (like 2.2.0. Check Docker Hub/xddeng/rediseen for full list)

A complete example using Docker follows below

docker network create test-net

docker run -d --network=test-net --name=redis-server redis

docker run \
    -d --network=test-net \
    -e REDISEEN_REDIS_URI="redis://:@redis-server:6379" \
    -e REDISEEN_DB_EXPOSED=0 \
    -e REDISEEN_KEY_PATTERN_EXPOSED="^key:([0-9a-z]+)" \
    -p 8000:8000 \
    xddeng/rediseen:latest

curl -s http://localhost:8000/0

Result is like

{
  "count": 0,
  "total": 0,
  "keys": null
}

Then you can execute

docker exec -i redis-server redis-cli set key:0 100

curl -s http://localhost:8000/0

and you can expect output below

{
  "count": 1,
  "total": 1,
  "keys": [
    {
      "key": "key:0",
      "type": "string"
    }
  ]
}
