Redis-Caching-Demo

We have build one PoC to Cache OData API responses. To store cache data we are using Redis Database.

Packages which are used here:

• Microsoft.AspNetCore.OData
• Microsoft.Extensions.Caching.StackExchangeRedis
• Microsoft.EntityFrameworkCore
• Microsoft.EntityFrameworkCore.SqlServer

Services used:

• AddStackExchangeRedisCache (Microsoft.Extensions.Caching.StackExchangeRedis)
• AddRedisOutputCache (Custom)

Middleware used:

• UseOutputCache()

Description:

• Here we add service AddStackExchangeRedisCache which is used to make connection with Redis Database and inject the IDistributedCache dependency for RedisCache implementation.
• In custom AddRedisOutputCache service, we added AddOutputCache service and remove IOutputCacheStore dependency which is in-memory cache store implementation. Then added IOutputCacheStore dependency with our custom RedisOutputCacheStore implementation.

Deploy Poc On Docker:

Here We added docker file and docker compose file to run multiple container at a time.

• Here total 3 container will be created.

1. ms-sql-server
2. redis(cache)
3. odatarediscaching

Description:

• During creating container migration will be applyed so database will be created.
• There is volumn which we have used to store data. During creating container you will get blank database.
• Here we add docker secret for security purpose in docker-compose.yml file.
• Here we have created two secret one is for sql and other one for redis database password.

How to create Docker Secrets?

• To create Docker secret use below command:
• echo "SetPassword" | docker secret create NameOfSecret -

As per your requirement you can create your secrets and use in docker-compose.yml file.

How to Deploy on docker?

1. Create secrets.
2. Use below command to create image:
   • docker compose up -d
   • Using this command containers will be created.
3. To remove container
   • docker compose down
