I have an Angular Universal application with the following Dockerfile:

FROM node:14-alpine
WORKDIR /app

COPY package.json /app
COPY dist/webapp /app/dist/webapp

ENV NODE_ENV "production"
ENV PORT 80

EXPOSE 80
CMD ["npm", "run", "serve:ssr"]

And I can deploy it to a Kubernetes cluster just fine but it keeps getting restarted every 10 minutes or so:

NAME                      READY   STATUS    RESTARTS   AGE
api-xxxxxxxxx-xxxxx       1/1     Running   0          48m
webapp-xxxxxxxxxx-xxxxx   1/1     Running   232        5d19h

Pod logs are clean and when I describe the pod I just see:

    Last State:     Terminated
      Reason:       Completed
      Exit Code:    0
      Started:      Tue, 22 Sep 2020 15:58:27 -0300
      Finished:     Tue, 22 Sep 2020 16:20:31 -0300

This is my deployment.yaml:

    tier: frontend

          image: $IMAGE_TAG
          ports:
            - containerPort: 80

How can I tell the reason it keeps restarting? Thanks!
