Example of deploying a custom Docker image into Google Cloud Run service using TypeScript. Image builds a simple HelloWorld web application in Ruby. You may change it to any language and runtime that can run on Linux and serve HTTP traffic.

1. Ensure you have the latest Node.js and NPM
2. Install the Pulumi CLI
3. Configure Pulumi to access your GCP account
4. Install Docker
5. Enable Docker to deploy to Google Container Registry with gcloud auth configure-docker

1. NPM dependencies:

   $ npm install
   

2. Create a new stack:

   $ pulumi stack init dev
   

3. Configure your GCP project and region:

   $ pulumi config set gcp:project <projectname>
   $ pulumi config set gcp:region <region>
   

4. Run pulumi up to deploy changes:

   $ pulumi up
   

5. Check the deployed Cloud Run endpoint:

   $ curl "$(pulumi stack output rubyUrl)"
   

6. Clean up your GCP and Pulumi resources:

   $ pulumi destroy
