Deploy simple nginx multi-container service NGINX/PHP-FPM

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
  • Artifact Registry
gcloud services enable run.googleapis.com artifactregistry.googleapis.com

Getting started

Declare the following environment variables.

# References your Google Cloud Project
export PROJECT_ID=<your-project-id>
# References your Artifact Registry repo name
export REPO_NAME="default"
# References your resource location
export REGION="us-west1"
# References final Cloud Run multi-contaienr service name
export MC_SERVICE_NAME="mc-php-example"
  1. Authenticate in gcloud cli.
gcloud auth login
  1. Create a repository within Artifact Registry.
gcloud artifacts repositories create ${REPO_NAME} --repository-format=docker
  1. Build the nginx and hellophp container images for our multi-container service.
# Creating image from the Dockerfile within nginx/ dir.
gcloud builds submit --tag=${REGION}-docker.pkg.dev/${PROJECT_ID}/${REPO_NAME}/nginx ./nginx

# Creating image from the Dockerfile within php-app/ dir.
gcloud builds submit --tag=${REGION}-docker.pkg.dev/${PROJECT_ID}/${REPO_NAME}/php ./php-app
  1. Configure the service with the appropriate memory limit.

You will see as you read through service.yaml, that the memory limit has been explicitly set to 335M. This leaves ~143M for PHP processes after allocating 192M for opcache. See how we got here and read more about how to optimize for concurrency.

Note: This sample does not contain extra configuration to tune php-fpm settings to specify the number of workers to correlate with the container concurrency.

  1. Deploy the multi-container service.

From within service.yaml, customize the service.yaml file with your own project values by replacing the following PROJECT_ID, MC_SERVICE_NAME, REGION, and REPO_NAME.

Once you've replaced the values, you can deploy from root directory (hello-php-nginx-sample/).

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)
  • hellophp: application container

The Cloud Run Multi-container service will default access to port 8080, where nginx container will be listening and proxy request over to hellophp container at port 9000.

Verify by using curl to send an authenticated request:

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