Loading

Init

For local self-hosted:

dapr init

For kubernetes support:

dapr init --kubernetes --wait

Create Solution

mkdir store-manager
cd store-manager

Create Projects

dotnet new classlib -o shared
dotnet new webapi -o actors-api

Dashboard

Runs on port 8080:

dapr dashboard 

Redis cli

npm install -g redis-cli
rdcli -h localhost -a "" -p 6379
KEYS *
HGETALL DaprCounter||counter
del DaprCounter||counter

Alternatively, you can access Docker CLI:

docker exec -it dapr_redis redis-cli

• Clean Redis:

FLUSHALL

• Make sure:

KEYS *

If funning in k8s, do docker ps to discover the container name of the REDIS running in K8s. and then do the above docker command:

docker exec -it k8s_redis_redis-75db659ddc-q6jfn_dapr-storemanager_b116ad62-7b4e-4a75-968f-39f84ce8a16c_0 redis-cli

Docker

Docker files have to be at the roor because they need to include the shared library.

docker image build -t store-manager/entities:1.0 . -f Dockerfile-entities
docker container run -it  -p 6002:6002 store-manager/entities:1.0
docker inspect <container-id>

Make sure the ASP.Net core project run using 0.0.0.0 as opposed to localhost. Otherwise the error is socket hang whikle running in Docker.

You can also get into the Docker container:

docker run  -it store-manager/entities:1.0 /bin/bash

To push to Docker hub:

docker login
docker push khaledhikmat/image-name:tag

Kubernetes

bash ./start.sh
kubectl get pods -n dapr-storemanager
basg ./stop.sh

Notes

• Improve Mermaid diagram
• How about local K8s?
• How about Azure Container Apps?
• Use Azure Bicep to deploy using Github actions
