create a user and a project

we ll be using the command line tool

pacaur -S google-cloud-sdk

create a GCP service account; format of account is email address

SA_EMAIL=$(gcloud iam service-accounts --format='value(email)' create k8s-gcr-auth-ro)

create the json key file and associate it with the service account and save it in k8s-gcr-auth-ro.json

gcloud iam service-accounts keys create k8s-gcr-auth-ro.json --iam-account=$SA_EMAIL

get the project id

PROJECT=$(gcloud config list core/project --format='value(core.project)')

add the IAM policy binding for the defined project and service account

gcloud projects add-iam-policy-binding $PROJECT --member serviceAccount:$SA_EMAIL --role roles/storage.objectViewer

and now we ct create a secret which we ll use to store the user login json info in.


kubectl create secret docker-registry $SECRETNAME \
  --docker-server= \
  --docker-username=_json_key \ \
  --docker-password="$(cat k8s-gcr-auth-ro.json)"

now we grab an example project ( for service static files using alpine nginx )

cd ~/Projects
git clone
cd k3s-nginx 

let’s get building an image called blog. the Dockerfile in this example repo will copy all other files from the folder ( in this case a index.html exists )

docker build -t blog .
docker run -p 80:80 blog

tag image and push to registry

docker tag blog$PROJECT/blog
docker push$PROJECT/blog

and last we can add additional parameters to tell the pod to use these credentials

apiVersion: v1
kind: Pod
  name: <pod_name>
    - name: <container_name>
      - name: your_secret_name
