Steps to Reproduce the Problem
Using the attached docker file and deployment file to deploy my application in my GKE cluster where already dapr is installed:
Note:
Have installed dapr in both the remote machine and my local machine (since am using the google cloud sdk shell to run the deployment files from my local)
Your Dockerfile indicates you're using the openjdk image and expecting Dapr to be in it, which it isn't .
Your Dockerfile indicates you're using the openjdk image and expecting Dapr to be in it, which it isn't .
-- i checked the dapr website it says for development installing dapr runtime through a docker file is okay but for production environment it is not suggested. So, can you kindly suggest which jdk image shall i use or if there is any way to use an image with the Dapr in it
If you're running in Kubernetes you can install Dapr to the cluster to leverage it fully: https://docs.dapr.io/operations/hosting/kubernetes/kubernetes-overview/
I personally use the helm chart.
If for some reason you want to run dapr within your docker image, you need to download + install it in your runtime environment (e.g.: run wget or curl, and extract it)
Please, use K8s for running Dapr sidecar as a container. We do not recommend using sidecar built into the app's Docker image since it does not have the orchestration provided by Dapr's control plane in K8s (components, service discovery, mTLS, etc).
