CANedge Google Cloud Platform Deployment

This repository provides Terraform configurations to automate the deployment of CANedge data processing infrastructure on Google Cloud Platform. The deployment is split into three parts:

1. Input Bucket Deployment: Creates an input bucket for storing uploaded CANedge log files
2. MF4-to-Parquet Deployment: Creates an output bucket and Cloud Function for DBC decoding MDF to Parquet
3. BigQuery Deployment: Creates BigQuery resources for querying Parquet data

---

Deployment

Setup Instructions

1. Log in to the Google Cloud Console
2. Select your project from the dropdown (top left)
3. Click on the Cloud Shell icon (>_) to open Cloud Shell (top right)
4. Once Cloud Shell is open, run the following command to clone this repository:

cd ~ && rm -rf canedge-google-cloud-terraform && git clone https://github.com/CSS-Electronics/canedge-google-cloud-terraform.git && cd canedge-google-cloud-terraform

 

1: Deploy Input Bucket

If you're just getting started, first deploy the input bucket where your CANedge devices will upload MF4 files:

chmod +x deploy_input_bucket.sh && ./deploy_input_bucket.sh --project YOUR_PROJECT_ID --region YOUR_REGION --bucket YOUR_BUCKET_NAME

Replace:

• YOUR_PROJECT_ID with your active Google Cloud project ID (e.g. bigquery7-464008)
• YOUR_REGION with your desired region (e.g., europe-west1 - see this link for available regions)
• YOUR_BUCKET_NAME with your desired bucket name (e.g. canedge-test-bucket-20)

 

2: Deploy MF4-to-Parquet Pipeline

Once you have an input bucket set up, you can optionally deploy the processing pipeline to automatically DBC decode uploaded MF4 files to Parquet format:

chmod +x deploy_mdftoparquet.sh && ./deploy_mdftoparquet.sh --project YOUR_PROJECT_ID --bucket YOUR_INPUT_BUCKET_NAME --id YOUR_UNIQUE_ID --email YOUR_EMAIL --zip YOUR_FUNCTION_ZIP

Replace:

• YOUR_PROJECT_ID with your Google Cloud project ID
• YOUR_INPUT_BUCKET_NAME with your input bucket name
• YOUR_UNIQUE_ID with a short unique identifier (e.g. datalake1)
• YOUR_EMAIL with your email address to receive notifications
• YOUR_FUNCTION_ZIP with the function ZIP file name (e.g. mdf-to-parquet-google-function-v3.1.0.zip)
  • Download the ZIP from the CANedge Intro (Process/MF4 decoders/Parquet data lake/Google)

Note

Make sure to upload the ZIP to your input bucket root before deployment

Important

If the deployment fails with a message regarding Eventarc propagation delay, simply re-run the deployment after a few minutes to complete it.

 

3: Deploy BigQuery

After setting up the MF4-to-Parquet pipeline, you can deploy BigQuery to query your Parquet data lake:

chmod +x deploy_bigquery.sh && ./deploy_bigquery.sh --project YOUR_PROJECT_ID --bucket YOUR_INPUT_BUCKET_NAME --id YOUR_UNIQUE_ID --dataset YOUR_DATASET_NAME --zip YOUR_FUNCTION_ZIP

Replace:

• YOUR_PROJECT_ID with your Google Cloud project ID
• YOUR_INPUT_BUCKET_NAME with your input bucket name
• YOUR_UNIQUE_ID with the same unique identifier used in the previous step (e.g. datalake1)
• YOUR_DATASET_NAME with your desired BigQuery dataset name (e.g. dataset1)
• YOUR_FUNCTION_ZIP with the BigQuery function ZIP file name (e.g. bigquery-map-tables-vT.3.0.zip)
  • Download the ZIP from the CANedge Intro (Process/MF4 decoders/Parquet data lake - interfaces/Google)

Note

Make sure to upload the ZIP to your input bucket root before deployment

Troubleshooting

If you encounter issues with either deployment:

• When deploying the MF4-to-Parquet pipeline for the first time in a Google project, the deployment may fail due to propagation delay on Eventarc permissions - in this case, simply re-run the deployment after a few minutes
• Make sure you have proper permissions in your Google Cloud project
• Use unique identifiers with the --id parameter to avoid resource conflicts
• Check the Google Cloud Console logs for detailed error messages
• For the MF4-to-Parquet and BigQuery deployments, ensure the relevant function ZIP files are uploaded to your input bucket before deployment
• Contact us if you need deployment support
