在 GitHub 查看 ↗Bank of Anthos
Bank of Anthos is a sample HTTP-based web app that simulates a bank's payment processing network, allowing users to create artificial bank accounts and complete transactions.
Google uses this application to demonstrate how developers can modernize enterprise applications using Google Cloud products, including: Google Kubernetes Engine (GKE), Anthos Service Mesh (ASM), Anthos Config Management (ACM), Migrate to Containers, Spring Cloud GCP, Cloud Operations, Cloud SQL, Cloud Build, and Cloud Deploy. This application works on any Kubernetes cluster.

Service architecture
| Service | Language | Description |
|---|---|---|
| frontend | Python | Exposes an HTTP server to serve the website. Contains login page, signup page, and home page. |
| ledger-writer | Java | Accepts and validates incoming transactions before writing them to the ledger. |
| balance-reader | Java | Provides efficient readable cache of user balances, as read from ledger-db. |
| transaction-history | Java | Provides efficient readable cache of past transactions, as read from ledger-db. |
| ledger-db | PostgreSQL | Ledger of all transactions. Option to pre-populate with transactions for demo users. |
| user-service | Python | Manages user accounts and authentication. Signs JWTs used for authentication by other services. |
| contacts | Python | Stores list of other accounts associated with a user. Used for drop down in "Send Payment" and "Deposit" forms. |
| accounts-db | PostgreSQL | Database for user accounts and associated data. Option to pre-populate with demo users. |
| loadgenerator | Python/Locust | Continuously sends requests imitating users to the frontend. Periodically creates new accounts and simulates transactions between them. |
Interactive quickstart (GKE)
The following button opens up an interactive tutorial showing how to deploy Bank of Anthos in GKE:
Quickstart (GKE)
-
Ensure you have the following requirements: - Google Cloud project. - Shell environment with
gcloud,git, andkubectl. -
Clone the repository.
sh
git clone https://github.com/GoogleCloudPlatform/bank-of-anthos
cd bank-of-anthos/
- Set the Google Cloud project and region and ensure the Google Kubernetes Engine API is enabled.
sh
export PROJECT_ID=<PROJECT_ID>
export REGION=us-central1
gcloud services enable container.googleapis.com \
--project=${PROJECT_ID}
Substitute <PROJECT_ID> with the ID of your Google Cloud project.
- Create a GKE cluster and get the credentials for it.
sh
gcloud container clusters create-auto bank-of-anthos \
--project=${PROJECT_ID} --region=${REGION} \
--labels dev-tutorial=bank-of-anthos
Creating the cluster may take a few minutes.
- Deploy Bank of Anthos to the cluster.
sh
kubectl apply -f ./extras/jwt/jwt-secret.yaml
kubectl apply -f ./kubernetes-manifests
- Wait for the pods to be ready.
sh
kubectl get pods
After a few minutes, you should see the Pods in a Running state:
NAME READY STATUS RESTARTS AGE
accounts-db-6f589464bc-6r7b7 1/1 Running 0 99s
balancereader-797bf6d7c5-8xvp6 1/1 Running 0 99s
contacts-769c4fb556-25pg2 1/1 Running 0 98s
frontend-7c96b54f6b-zkdbz 1/1 Running 0 98s
ledger-db-5b78474d4f-p6xcb 1/1 Running 0 98s
ledgerwriter-84bf44b95d-65mqf 1/1 Running 0 97s
loadgenerator-559667b6ff-4zsvb 1/1 Running 0 97s
transactionhistory-5569754896-z94cn 1/1 Running 0 97s
userservice-78dc876bff-pdhtl 1/1 Running 0 96s
- Access the web frontend in a browser using the frontend's external IP.
sh
kubectl get service frontend | awk '{print $4}'
Visit http://EXTERNAL_IP in a web browser to access your instance of Bank of Anthos.
- Once you are done with it, delete the GKE cluster.
sh
gcloud container clusters delete bank-of-anthos \
--project=${PROJECT_ID} --region=${REGION}
Deleting the cluster may take a few minutes.
Additional deployment options
- Workload Identity: See these instructions.
- Cloud SQL: See these instructions to replace the in-cluster databases with hosted Google Cloud SQL.
- Multi Cluster with Cloud SQL: See these instructions to replicate the app across two regions using GKE, Multi Cluster Ingress, and Google Cloud SQL.
- Istio: See these instructions to configure an IngressGateway.
- Anthos Service Mesh: ASM requires Workload Identity to be enabled in your GKE cluster. See the workload identity instructions to configure and deploy the app. Then, apply
extras/istio/to your cluster to configure frontend ingress. - Java Monolith (VM): We provide a version of this app where the three Java microservices are coupled together into one monolithic service, which you can deploy inside a VM (eg. Google Compute Engine). See the ledgermonolith directory.
