Context

Playground example of using https://docs.dapr.io/ with Kind cluster. Scenario: two Spring Boot services Dapr1 and Dapr2 - when calling API - call chain: Nginx/Ingress -> Dapr1 -> Dapr2

NOTE: it is not secure / quality setup - only as dev playground

Setup:

• Install Docker and Kind

• Create Kind cluster and local docker registry > create-king-with-docker-reg.sh

• Setup ingress (Nginx) > kubectl apply -f k8-nginx.yml

• Install Dapr

• Install Dapr in K8 Kind cluster > create-dapr-k8.sh

• Build and deploy apps > cd code/dapr1 && make publish && make deploy > cd code/dapr2 && make publish && make deploy

• Dapr Dashboard at http://localhost:8080/configurations/daprsystem

• Call service:

  • for normal answer > curl 'localhost:8081/api/value?command=abc'

  • for error > curl 'localhost:8081/api/value?command=throw'

  • for delayed answer > curl 'localhost:8081/api/value?command=wait'
