What is this?

This is a really simple project that wires together a bunch of technology with a little bit of code to create a website of daily terrible "inspirational" quotes. Technology used:

• Google Cloud Scheduler
• Google Cloud Functions
• OpenAI GPT 3.5
• OpenAI DALL-E
• Google Cloud Storage
• GitHub Pages
• Jekyll

The following diagram shows how things are wired together:

Deploy

Before running locally or deploying, create an .env.yaml file in the _job directory containing:

OPENAI_API_KEY: {key from OpenAI}

IMAGES_BUCKET_NAME: {Cloud Storage Bucket Name}
GCP_PROJECT_ID: {Project ID}

GITHUB_REPO: {GitHub repo: username/reponame}
GITHUB_TOKEN: {GitHub token, must be able to create content at the above repo}

GCP

Before continuing, ensure that the following APIs are enabled:

• Cloud Run
• Cloud Build
• EventArc
• Cloud Functions
• Cloud Storage

Setup a Service Account

Create it

gcloud iam service-accounts create inspiration-ai-uploader --project inspiration-ai

Give it permissions:

# Allow it to upload to Cloud Storage
gcloud projects add-iam-policy-binding inspiration-ai --member="serviceAccount:inspiration-ai-uploader@inspiration-ai.iam.gserviceaccount.com" --role=roles/storage.objectCreator

# Allow it to invoke a Cloud Function
gcloud projects add-iam-policy-binding inspiration-ai --member="serviceAccount:inspiration-ai-uploader@inspiration-ai.iam.gserviceaccount.com" --role=roles/run.invoker

Create a Cloud Storage Bucket

gcloud storage buckets create gs://static-inspiration-ai --project=inspiration-ai --default-storage-class=standard --location=europe-north1 --uniform-bucket-level-access

Make the bucket public:

gcloud storage buckets add-iam-policy-binding gs://static-inspiration-ai --member=allUsers --role=roles/storage.objectViewer

Create a Pub/Sub Topic

To create a pubsub topic to trigger the cloud function, run:

gcloud pubsub topics create inspiration-ai_generate

Deploy the Cloud Function

See _job/deploy_function.sh:

gcloud functions deploy inspiration-ai-function \
--project=inspiration-ai \
--gen2 \
--runtime=python311 \
--region=northamerica-northeast1 \
--source=. \
--entry-point=generate_inspiration \
--trigger-topic=inspiration-ai_generate \
--service-account=inspiration-ai-uploader@inspiration-ai.iam.gserviceaccount.com \
--env-vars-file .env.yaml

Testing

Local

Run the function in local mode:

cd _job
./run-function.sh

Simulate a pubsub event, run the function:

cd _job
./test-function.sh

Deployed

To generate a quote for a specific day, run:

gcloud pubsub topics publish inspiration-ai_generate --message="{\"date\":\"2023-10-27\"}" --project=inspiration-ai
