Imagine

• Create Firestore database, i.e. Datastore in native mode, to persist the confirmed bookings.

• Implement CRUD

Create

Create Datastore in native mode in console for project serverless-devops-play - maybe not necessary?

Create Firebase project associated to serverless-devops-play

gcloud config list

firebase login
firebase init                         # see output in firebase_init.out
firebase projects:list
firebase database:instances:list

firebase database:instances:create bookings-play
firebase database:instances:list

Change Firestore rules

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

Set Service Account to access Firestore database

export LOCAL_CREDENTIALS_DIR=<local credentials directory>

export PROJECT_ID=serverless-devops-play

SA_NAME=firestore-play

gcloud iam service-accounts create ${SA_NAME} \
    --description="Service account to access Firestore API" \
    --display-name="${SA_NAME}"
    
gcloud projects add-iam-policy-binding ${PROJECT_ID} \
    --member "serviceAccount:${SA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com" --role "roles/firebasedatabase.admin"    
    
    
gcloud iam service-accounts keys create ${LOCAL_CREDENTIALS_DIR}/${PROJECT_ID}-${SA_NAME}.json \
  --iam-account ${SA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com
  

export GOOGLE_APPLICATION_CREDENTIALS="${LOCAL_CREDENTIALS_DIR}/${PROJECT_ID}-${SA_NAME}.json"
ls -l $GOOGLE_APPLICATION_CREDENTIALS

Edit main.go and run it

go mod init

go run main.go
