🌍 Live demo

Setup

The project can be run locally and deployed on the cloud - in our case to Google Cloud via Pulumi.

The below setup assumes you've already cloned the project locally.

1️⃣ Google Cloud setup
  1. Create a new Google Cloud project.
  2. Create a Service Account for the infrastructure as code setup with the following roles:
  3. Export a JSON API key for your Service Account and call it credentials-gcp-infra.json.
  4. Signup and Install Pulumi locally.
  5. Create a Pulumi access token and login locally using pulumi login.
  6. The project uses Pulumi micro-stacks to deploy the microservices individually. Each microservice has a corresponding infra folder containing its Pulumi.yaml infrastructure program, eg landing-page-web/infra. To get the project going, you will need to manually initialise each microservice on GCP using the Pulumi scripts.
The order to do this matters, so go with common/infra first, then all other microservices, then proxy-web/infra. The reason is that the resouces are created incrementally at each stage and we currently have no way synchronize them.
  1. The steps to deploy a microservice's infrastructure is the same for all:
    1. Navigate to its infra folder.
    2. Paste the credentials-gcp-infra.json file.
    3. Create a new empty Pulumi project with no resources using the pulumi new command and follow the instructions:
      • you can use the prompt Empty project with no resources for Pulumi AI;
      • you can use prod as your stack name;
    4. Replace the name in the microservice Pulumi.yaml with the value you entered in the prompt.
    5. Open Pulumi.prod.yml and replace the gcp:project value with your project id.
    6. Run pulumi up to automatically create the required microservice infrastructure.
    7. Repeat for the remaining microservices.
2️⃣ Local setup
  1. Install Docker Desktop and start it up. No additional configuration is required as the project uses Docker Compose to run locally. Checkout the docker folder for the setup.
  2. Install IntelliJ. This project has been tested with IntelliJ IDEA 2023.2.5.
  3. Open the root project with IntelliJ and wait for it to initialise.

Run locally

After completing the setup, you should be able to run the project locally using the Personal-Website-Docker IntelliJ IDE configuration. There is a landing page that should be available when you navigate to your localhost url.

CI and cloud deployment

This is really up to you! However, we've provided our setup below.

GitHub Actions

The project is configured to build with GitHub Actions and have a separate workflow for each microservice. Checkout the .github folder for details. Follow these steps to configure the CI environment:

  1. Add your Pulumi access token as a GitHub encrypted secret with the name PULUMI_ACCESS_TOKEN.
  2. Add an additional GCP_SA_KEY_INFRA GitHub encrypted secret, containing the raw JSON API key for the above infrastructure as code Service Account.
  3. (Optional) Install the Pulumi GitHub app to get automated summaries of your infrastructure as code changes directly on your PR.

Once this is done:

  • opening pull requests against the repo will trigger build/test checks as well as infrastructure changes preview for the microservice that has been changed;
  • merging pull requests to the main branch deploys the changes to the corresponding microservice to Google Cloud;
