如何获取运行我的 Web 应用程序的容器的 ID/名称来满足当前用户请求

Question

We are using Dockers and Kubernetes to containerize my.Net web application and scale up to 8-9 replicas. So we installed Dockers (in my Win 10 machine) and used Linux containers.

Orchestration is done by Kubernetes. I would like to get the name/id of the container in which my web application is running to serve the current user request.

Could not find a way to get the id/name of the container from my.Net Web application. Please share me your thoughts on this.

Regards

You can expose Pod fields as environment variables, the field metadata.name will contain the name of the Pod.

Documentation and example: https://kubernetes.io/docs/tasks/inject-data-application/environment-variable-expose-pod-information/#use-container-fields-as-values-for-environment-variables

Edit: You can also use System.Environment.MachineName as @vahdet commented earlier. The hostname of the container is the pod id.
