Deploy Casdoor in k8s

We have given a basic example of deploying Casdoor into k8s. In the root folder of casdoor, there exists a file named "k8s.yaml", which includes an example minimum configuration to be used in deploying casdoor in k8s, a deployment and a service.

First, make sure that you have modified the conf/app.conf so that the casdoor can successfully connect to the database, and the database is running. Second, make sure k8s is able to pull the necessary images.

Run

kubectl apply -f k8s.yaml

And soon you can see the result via command kubectl get pods

The content of k8s.yaml is as follow

# this is only an EXAMPLE of deploying casddor in kubernetes
# please modify this file according to your requirements
apiVersion: v1
kind: Service
metadata:
  #EDIT IT: if you don't want to run casdoor in default namespace, please modify this field

          imagePullPolicy: Always
          ports:
            - containerPort: 8000
          volumeMounts:
            # the mounted directory path in THE CONTAINER
            - mountPath: /conf
              name: conf
          env:       
            - name: RUNNING_IN_DOCKER
              value: "true"
      #if you want to deploy this in real prod env, consider the config map
      volumes:
        - name: conf
          hostPath:
            #EDIT IT: the mounted directory path in THE HOST
            path: /conf

This file is merely an example. For example, you can choose to use a namespace other than default, use a service type instead of nodeport to expose the casdoor, or use a use config map in k8s to mount the configuration file, which is a more recommended way in k8s.
