Run BaGetter on Google Cloud Platform


This page is a work in progress!

We're open source and accept contributions! Fork us on GitHub.

Before you begin, you should decide which AppEngine region you will use. For best performance, Cloud Storage and Cloud SQL should be located in the same region as your AppEngine deployment.

Google Cloud Storage

Packages can be stored in Google Cloud Storage.


Follow the instructions in Using Cloud Storage to create a bucket.


NOTE: If you plan to use AppEngine, skip this part and follow the AppEngine instructions below.

Set up a service account, create and download a key as JSON file. Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path to the JSON file you downloaded. The file should contain something like this:

"type": "service_account",
"project_id": "your_project",
"private_key_id": "6950mvh3690mg3h90jg3986vgm",
"private_key": "-----BEGIN PRIVATE KEY-----\hriv eohgrup4nhg8594nhvpog59p4w5...",
"client_email": "",
"client_id": "49826518658461496",
"auth_uri": "",
"token_uri": "",
"auth_provider_x509_cert_url": "",
"client_x509_cert_url": "",
"universe_domain": ""

Configure BaGetter to use Google Cloud Storage by updating the appsettings.json file:


"Storage": {
"Type": "GoogleCloud",
"BucketName": "your-gcs-bucket"


Or set the Storage__Type and Storage__BucketName environment variables in your deployment (i.e. AppEngine project) accordingly.

Google Cloud SQL

  • Follow the instructions in Using Cloud SQL to create a (for example) 2nd Gen MySQL 5.7 Google Cloud SQL instance. The default options should work well.
  • Create a database named bagetter. This can be done through the Google Cloud Console. Use utf8mb4 as the Character set.
  • Follow Configuring SSL/TLS to create a client certificate. Download the three files it creates.
  • Convert the PEM to a PFX by running openssl pkcs12 -inkey client-key.pem -in client-cert.pem -export -out client.pfx
    • One way to obtain OpenSSL on Windows is to install Git Bash.
  • Configure BaGetter to use Google Cloud SQL by updating the appsettings.json file:
"Database": {
"Type": "MySql",
"ConnectionString": "Server=YOURIP;User Id=root;Password=***;Database=bagetter;CertificateFile=C:\\Path\\To\\client.pfx;CACertificateFile=C:\\Path\\To\\server-ca.pem;SSL Mode=VerifyCA"
  • Create the tables by running dotnet ef database update --context MySqlContext --project src\BaGetter

Google AppEngine

BaGetter can be hosted in Google AppEngine. See here for a tutorial on how to create a new AppEngine project.

Create a app.yaml file to publish the Docker container built by the Dockerfile in this repo. In the template below, make the following replacements:

  • PROJECT - your GCP project, as returned by gcloud config get-value project
  • REGION -- the GCP region your Google Cloud SQL database is in, e.g., us-central1 or us-west2
  • DBINSTANCE -- the name of your Google Cloud SQL database instance
  • DBNAME -- the name of the BaGetter database on that instance (e.g., bagetter in the instructions above)
  • PASSWORD -- the password for the database root user
  • BUCKETNAME -- the name of the Google Cloud Storage Bucket configured above
runtime: custom
env: flex

disk_size_gb: 10

cloud_sql_instances: "PROJECT:REGION:DBINSTANCE"

Database__Type: "MySql"
Database__ConnectionString: "Server=/cloudsql/PROJECT:REGION:DBINSTANCE;User Id=root;Password=PASSWORD;Database=DBNAME;SslMode=None"
Storage__Type: "GoogleCloud"
Storage__BucketName: "BUCKETNAME"
Search__Type: "Database"

To publish the application, run gcloud app deploy.
