Deploying to Google Cloud Run

In order to run this demo you will need the following requirements on your local computer:

• Docker
• Google Cloud CLI (Make sure its up to date and logged in)
• Python (>V3.8) if you want to edit and test the services, not necessary if just running the demo

First create a new project on Google Cloud to deploy all the resources required to run the demo using the following commands - take note of the project ID assigned to the new project for the next step and also ensure billing is linked to the project so the setup script step doesn't fail:

gcloud projects create otel-demo
# Get ID in case Google added no. to end
gcloud projects list
# Don't forget to ensure billing is linked to new project in console!

Next run the setup-gcr.sh bash script in the root of the project repository to setup all the Google Cloud resources for the project:

chmod +x ./setup-gcr.sh
./setup-gcr.sh <project-id>

Finally you can now use the deploy-gcr.sh script to deploy the services to Google Cloud Run for testing:

chmod +x ./deploy-gcr.sh
./deploy-gcr.sh

Note: All services will be deployed in region us-central-1. If you wish to use another region, please edit the bash scripts region variable at the top.

Finally go to the API service URL /docs' to see the OpenAPI docs for the REST API and try the greet` API. You should be able to see traces for each request you make on Google Cloud Trace in your console.
