Sample code to deploy a node.js app using npm in GCP Cloud Run
The script was built using Node v14.20.0. To run locally you need to have npm installed and then run the following commands:
npm install
npm start
These commands will first install any missing dependencies that are not present in the node_modules folder and then run the script. Also, make sure to copy the .env.tpl file to .env and update the environment variables with appropriate values.
Run the service locally using Docker, using the available Dockerfile.
local_port=8080
container_port=8080
docker_tag=node_cloud_run:latest
docker build . -t $docker_tag
docker run -p $local_port:$container_port -t $docker_tag
Deploying to Cloud Run is as easy as executing some commands and triggering the container push using the gcloud run command (this requires the Google Cloud SDK to be installed on your machine). Otherwise, you need to trigger the push manually on Cloud Run plaform
# Only run this if this is the first time running cloud run on your GCP account
gcloud services enable containerregistry.googleapis.com
gcloud auth configure-docker
# Tag container image and push it to Google Cloud Registry
docker_tag=node_cloud_run:latest
gcp_project_id=node-cloud-run-cloud-run
gcp_container_tag=node_cloud_run:latest
gcp_cloud_run_name=node-cloud-run
docker tag $docker_tag gcr.io/$gcp_project_id/$gcp_container_tag
docker push gcr.io/$gcp_project_id/$gcp_container_tag
# Deploy (start) container using gcloud
gcloud run deploy $gcp_cloud_run_name --image gcr.io/$gcp_project_id/$gcp_container_tag
There is currently a service running on Cloud Run under the following host: https://node-cloud-run-something.a.run.app
