Cannot bind ports to my container in Google Container optimized VM - docker

Question

I'm trying to run a docker container on Google Container-optimized VM in GCE.
Here is my dockerfile. I built a container image and push it to gcr.io.
FROM nginx:1.9
COPY config /etc/nginx
And I wrote a container manifest file.
version: v1beta2
containers:
- name: test
image: gcr.io/myproject/test
ports:
- name: http
hostPort: 80
containerPort: 80
- name: https
hostPort: 443
containerPort: 443
I deployed to GCE with the manifest file, but port binding was not as I had expected. Why did the host port 80 and 443 redirect to google_containers/pause instead of myproject/test?
local$ gcloud compute instance create test \
--image container-vm \
--metadata-from-file google-container-manifest=container.yaml \
--zone us-central1-b \
--machine-type f1-micro \
--tags http-server,https-server
local$ gcloud compute ssh --zone us-central1-b test
test$ sudo docker ps -a

Answer 1

I had updated version of the manifest v1beta2 to v1 (v1beta3) and tried it again. The result of port binding seems to be same as previous one, but the container can communicate with external network through port 80 and 443.
