Open source C# Web Application to help Admin and understand a Redis database.

While trying to understand how Redis works I used the Redis CLI and redis-commander which is an AWESOME piece of software!

1. Create your own bridge network

   docker network create --driver bridge redis-bridge-network
   

2. Spin up a redis server if you don't have one

   docker run --name red-srv -d -p 6379:6379 --network redis-bridge-network redis:4.0.5-alpine redis-server --appendonly yes
   

3. Spin up redis administrator and pass the environment setting to tell it which redis server to connect to. If not set it will default to localhost:6379,allowAdmin=true

   docker run --name red-admin -d -p 8080:80 --network redis-bridge-network --env REDIS_CONNECTION=red-srv,allowAdmin=true  carlpaton/redis-administrator:latest
   

4. Access from http://localhost:8080

5. Cleanup

   docker kill red-srv
   docker rm red-srv
   docker kill red-admin
   docker rm red-admin
   docker network rm redis-bridge-network

https://redis.io/topics/data-types

• String
  • Strings are the most basic kind of Redis value. Redis Strings are binary safe, this means that a Redis string can contain any kind of data, for instance a JPEG image or a serialized Ruby object.
• Sorted Set
  • Redis Sorted Sets are similar to Redis Sets, non-repeating collections of Strings. The difference is, every member of a Sorted Set is associated with a score, that is used in order to take the sorted set ordered, from the smallest to the greatest score. While members are unique, the scores may be repeated.

In the Redis Administrator code base the following types have not as yet been touched/used.

• Set
  • Redis Sets are an unordered collection of strings. In Redis, you can add, remove, and test for the existence of members in O(1) time complexity.
• List
• Hash
• Stream

These are the projects inside the RedisAdministrator solution.

.Net Core MVC web application, that's quite a mouthful!

Tests that were used during the repository development, true integration tests as they will indeed hit the supplied database.

These are specified in the docker image build:

RUN dotnet test "./UnitTest/UnitTest.csproj" -c Release --no-build --no-restore
