Tweet Provider Demo

Setup

To run these demos locally, you will have first create a secret file (pipeline/secrets.json). These will be used by Dapr components at runtime. To get the Twitter API secretes you will need to register your app here.

{
    "Twitter": {
        "ConsumerKey": "",
        "ConsumerSecret": "",
        "AccessToken": "",
        "AccessSecret": ""
    }
}

Run it

Standalone Mode

Navigate to the tweet-provider directory and run:

cd tweet-provider
dapr run \
    --app-id tweet-provider \
    --app-port 8080 \
    --app-protocol http \
    --components-path ./config \
    go run main.go

The last line from the above command should be

✅  You're up and running! Both Dapr and your app logs will appear here.

Your tweets should appear in the logs now

Kubernetes

Create secret for tweet-provider to connect to Twitter API

kubectl create secret generic twitter-secret \
  --from-literal=consumerKey="" \
  --from-literal=consumerSecret="" \
  --from-literal=accessToken="" \
  --from-literal=accessSecret=""

Deploy the tweet-provider service and its components

kubectl apply -f tweet-provider/k8s/state.yaml
kubectl apply -f tweet-provider/k8s/pubsub.yaml
kubectl apply -f tweet-provider/k8s/twitter.yaml
kubectl apply -f tweet-provider/k8s/deployment.yaml
kubectl rollout status deployment/tweet-provider

If you have changed an existing component, make sure to reload the deployment and wait until the new version is ready

kubectl rollout restart deployment/tweet-provider
kubectl rollout status deployment/tweet-provider

Check Dapr to make sure components were registered correctly

kubectl logs -l app=tweet-provider -c daprd --tail 200
