Redis Connector Sample App

ASP.NET Core sample app illustrating how to use the Steeltoe Redis Connector to connect to a Redis server. This sample uses both Microsoft RedisCache and StackExchange ConnectionMultiplexer to work with the same Redis service.

General pre-requisites

  1. Installed .NET 8 SDK
  2. Optional: VMware Tanzu Platform for Cloud Foundry (optionally with Windows support) with Redis for VMware Tanzu Application Service or VMware Tanzu Cloud Service Broker and Cloud Foundry CLI

    [!NOTE] ASP.NET before v9 requires that Lua scripting is activated, which is disabled by default on Cloud Foundry (check your plan settings)

  3. Optional: VMware Tanzu Platform for Kubernetes v1.5 or higher and Kubernetes

Running locally

  1. Start a Redis docker container
  2. Run the sample 
    dotnet run

Upon startup, the app inserts a couple of key/value pairs into the bound Redis cache using both APIs. They are displayed on the home page.

Running on Tanzu Platform for Cloud Foundry

  1. Create a Redis service instance in an org/space 
    cf target -o your-org -s your-space
    • When using Redis for VMware Tanzu Application Service: 
      cf create-service p.redis on-demand-cache sampleRedisService
      or: 
      cf create-service p-redis shared-vm sampleRedisService
    • When using the Cloud Service Broker for Azure: 
      cf create-service csb-azure-redis your-plan sampleRedisService
    • When using the Cloud Service Broker for GCP: 
      cf create-service csb-google-redis your-plan sampleRedisService
  2. Wait for the service to become ready (you can check with cf services)
  3. Run the cf push command to deploy from source (you can monitor logs with cf logs redis-connector-sample)
    • When deploying to Windows, binaries must be built locally before push. Use the following commands instead: 
      dotnet publish -r win-x64 --self-contained
cf push -f manifest-windows.yml -p bin/Release/net8.0/win-x64/publish
  4. Copy the value of routes in the output and open in your browser

Running on Tanzu Platform for Kubernetes

Create Redis class claim

In order to connect to Redis for this sample, you must have a class claim available for the application to bind to. The commands listed below will create the claim, and the claim will be bound to the application via the definition in the workload.yaml that is included in the config folder of this project.

kubectl config set-context --current --namespace=your-namespace
tanzu service class-claim create my-postgresql-service --class postgresql-unmanaged

If you'd like to learn more about these services, see claiming services and consuming services in the documentation.

App deployment

To deploy from local source code:

tanzu app workload apply --local-path . --file ./config/workload.yaml -y

Alternatively, from locally built binaries:

dotnet publish -r linux-x64 --no-self-contained
tanzu app workload apply --local-path ./bin/Release/net8.0/linux-x64/publish --file ./config/workload.yaml -y

See the Tanzu documentation for details.

See the Official Steeltoe Connectors Documentation for a more in-depth walkthrough of the samples and more detailed information.
