How do I run a docker image on google container engine? - kubernetes

Question

I am trying to run a docker image in Google Container Engine. The instance comes up with no running docker images. I can ssh and run the docker commands and the service comes up. But nothing happens when I just launch the instance from the terminal. Can some one take a look at what I am doing wrong.
My docker file looks like
FROM golang
RUN mkdir -p /app
COPY . /app
RUN go get golang.org/x/tools/cmd/present
ENTRYPOINT cd /app && /go/bin/present -http=":8080"
EXPOSE 8080
containers.yaml looks like
version: v1beta3
containers:
- name: talks
image: sheki/talks
ports:
- name: http-port
containerPort: 8080
hostPort: 80'
The command to launch the instance is
gcloud compute instances create zoop \
--image container-vm \
--metadata-from-file google-container-manifest=containers.yaml \
--zone us-central1-a \
--machine-type f1-micro

You mentioned in your question that you are using google container engine, but in fact you are using the container vm (which is a bit different). If you want to use container engine, please check out the documentation to create a container cluster.
I ran your example, and in /var/log/kubelet.log saw the following error:
E0519 17:05:41.285556 2414 http.go:54] Failed to read URL: http://metadata.google.internal/computeMetadata/v1beta1/instance/attributes/google-cont
ainer-manifest: received 'version: v1beta3
containers:

', but couldn't parse as neither single (error unmarshaling JSON: json: cannot unmarshal string into Go value of type int: {Version:v1beta3 ID: UUID:

Port":8080,"hostPort":"80'","name":"http-port"}]}],"version":"v1beta3"}').
It looks like the documentation for container vms is out of date.
