run private docker images on Google Container Engine

Question

How do I run a docker image that I built locally on Google Container Engine?

Answer 1

Follow theses steps:

1. Setup some environment variables

   gcloud components update kubectl
   gcloud config set project <your-project>
   gcloud config set compute/zone <your-cluster-zone>
   gcloud config set container/cluster <your-cluster-name>
   gcloud container clusters get-credentials <your-cluster-name>
   

2. Tag your image

   docker tag <your-image> gcr.io/<your-project>/<your-image>
   

3. Push your image

   gcloud docker push gcr.io/<your-project>/<your-image>
   

4. Create a pod manifest for your container: my-pod.yaml

   id: my-pod
   kind: Pod
   apiVersion: v1
   desiredState:
     manifest:
       containers:
       - name: <container-name>
         image: gcr.io/<your-project>/<your-image>
       ...
   

5. Schedule this pod

   kubectl create -f my-pod.yaml
   

6. Repeat from step (4) for each pod you want to run. You can have multiple definitions in a single file using a line with --- as delimiter.
