schadokar/redis-go-server repository overview

⁠Redis-Go-Server

The project is saved in github⁠.

⁠Prerequisite

The Redis DB must be up and running. It can be locally hosted, Redis docker image or cloud-based.

Use docker-compose to pass the Redis DB details to the server.

Set the environment variable of the redis-db:

  • REDIS_DB_URL=URL
  • REDIS_DB_PASSWORD=Password
  • REDIS_DB=db index

Note If the password is an empty string "", don't send the empty string.

REDIS_DB_PASSWORD=

It will take that as an empty string.

⁠Instructions

⁠Pull the image
docker pull schadokar/redis-go-server
⁠Create a docker-compose file
version: "2"

services:
  redis-db:
    image: redis:alpine
    ports:
      - 6379:6379
    container_name: redis-db

  redis-go-server:
    image: schadokar/redis-go-server:latest

    environment:
      - REDIS_DB_URL=redis-db:6379
      - REDIS_DB_PASSWORD=
      - REDIS_DB=0
    ports:
      - 8080:8080
    depends_on:
      - redis-db
    container_name: redis-go-server

First, we're pulling the redis:alpine image and running it as redis-db container.
The second image is schadokar/redis-go-server which is running as redis-go-server container.

Check the environment variables.

⁠Endpoints of the server

There are 3 endpoints of the server:

  • POST METHOD set
    It takes a json object with 2 keys: "key" and "value"
{
    "key": "strongest-avenger",  
    "value": "thor"
}
  • GET METHOD get
    Return all the keys stored in the Redis DB.
  • GET METHOD get/{key}
    Return the value of the key
⁠Example
  • Run the docker-compose file
docker-compose -f <file-path> up -d

Output  

docker-compose -f ./docker-compose.yaml up -d  
Creating network "deployments_default" with the default driver
Creating redis-db ... done
Creating redis-go-server ... done
  • Save a key-value pair in the Redis DB using cURL
curl -d '{"key":"strongest-avenger","value":"thor"}' -X POST http://localhost:8080/set
