Google Cloud Run Python Samples

This directory contains samples for Google Cloud Run. Cloud Run runs stateless containers on a fully managed environment or in your own GKE cluster.

Samples

Sample	Description	Deploy
Hello World ➥	Quickstart
Cloud Pub/Sub	Handling Pub/Sub push messages
Cloud SQL (MySQL)	Use MySQL with Cloud Run	-
Cloud SQL (Postgres)	Use Postgres with Cloud Run	-
Django	Deploy Django on Cloud Run	-
Identity Platform	Authenticate users and connect to a Cloud SQL postgreSQL databases

For more Cloud Run samples beyond Python, see the main list in the Cloud Run Samples repository.

Setup

Set up for Cloud Run development
Clone this repository:
```
git clone https://github.com/GoogleCloudPlatform/python-docs-samples.git
```
Note: Some samples in the list above are hosted in other repositories. They are noted with the symbol "➥".

How to run a sample locally

Install docker locally

Build the sample container:

export SAMPLE=<SAMPLE_NAME>
cd $SAMPLE
docker build --tag $SAMPLE .

Run containers locally

With the built container:

PORT=8080 && docker run --rm -p 8080:${PORT} -e PORT=${PORT} $SAMPLE

Overriding the built container with local code:

PORT=8080 && docker run --rm \
    -p 8080:${PORT} -e PORT=${PORT} \
    -v $PWD:/app $SAMPLE

Injecting your service account key for access to GCP services:

# Set the name of the service account key within the container
export SA_KEY_NAME=my-key-name-123

PORT=8080 && docker run --rm \
    -p 8080:${PORT} \
    -e PORT=${PORT} \
    -e GOOGLE_APPLICATION_CREDENTIALS=/tmp/keys/${SA_KEY_NAME}.json \
    -v $GOOGLE_APPLICATION_CREDENTIALS:/tmp/keys/${SA_KEY_NAME}.json:ro \
    -v $PWD:/app $SAMPLE

Use the --volume (-v) flag to inject the credential file into the container (assumes you have already set your GOOGLE_APPLICATION_CREDENTIALS environment variable on your machine)
Use the --environment (-e) flag to set the GOOGLE_APPLICATION_CREDENTIALS variable inside the container

Learn more about testing your container image locally.

Deploying

Set an environment variable with your GCP Project ID

export GOOGLE_CLOUD_PROJECT=<PROJECT_ID>

Submit a build using Google Cloud Build

gcloud builds submit --tag gcr.io/${GOOGLE_CLOUD_PROJECT}/${SAMPLE}

Deploy to Cloud Run

gcloud run deploy $SAMPLE --image gcr.io/${GOOGLE_CLOUD_PROJECT}/${SAMPLE}
