Deploy simple nginx multi-container service

A Google Cloud Project is required in order to run the sample.

Enable required APIs

The project should have the following API's enabled:

  • Cloud Run
  • Secret Manager
gcloud services enable secretmanager.googleapis.com run.googleapis.com

Add nginx server configuration to Secret Manager

Instead of packaging the nginx config into the container image, the config will be mounted as a volume at runtime using Secret Manager. This allows for separation of config from code.

In Kubernetes, while you are able to mount different volume types, Cloud Run currently provides secret volume as a lightweight volume mount. If you need a full filesystem, see Using network file systems. In service.yaml, look for nginx-conf-secret volume mount and nginx_config secret name references.

Follow along either using the gcloud commands in your terminal or the Google Cloud Console site to add the nginx_config secret.

gcloud CLI

The following creates a new secret in Secret Manager and adds value (new version) from local file nginx.conf.

gcloud secrets create nginx_config --replication-policy="automatic" --data-file="./nginx.conf"

Grant your compute service account to have access to your newly created secret.

export PROJECT_NUMBER=$(gcloud projects describe $(gcloud config get-value project) --format='value(projectNumber)')
gcloud secrets add-iam-policy-binding nginx_config --member=serviceAccount:$PROJECT_NUMBER[email protected] --role='roles/secretmanager.secretAccessor'

OR

Console UI

  • Go to the Secret Manager UI
  • Select + Create Secret and name it nginx_config with the contents of nginx.conf
  • Click Create Secret

Deploy the multi-container service

From inside the hello-nginx-sample directory, declare an environment variable MC_SERVICE_NAME to store your custom service name string.

export MC_SERVICE_NAME=<service-name>
export REGION = us-central1

# Substituting above env vars
sed -i -e s/MC_SERVICE_NAME/${MC_SERVICE_NAME}/g -e s/REGION/${REGION}/g service.yaml

# Deploy your service
gcloud run services replace service.yaml

By default, the above command will deploy the following containers into a single service:

  • nginx: serving ingress container (entrypoint)
  • hello: sidecar container

The Cloud Run Multi-container service will default access to port 8080, where nginx container will be listening and proxy request over to hello container at port 8888.

Try it out

Use curl to send an authenticated request:

curl --header "Authorization: Bearer $(gcloud auth print-identity-token)" <cloud-run-mc-service-url>

Allow unauthenticated requests

To allow un-authenticated access to containers:

gcloud run services add-iam-policy-binding $MC_SERVICE_NAME \
    --member="allUsers" \
    --role="roles/run.invoker"

Visit the Cloud Run url or use curl to send a request:

curl <cloud-run-mc-service-url>
