### Running Spring Boot examples
|
||||
|
||||
The Spring Boot integration for Dapr use [Testcontainers](https://testcontainers.com) to set up a local environment development flow that doesn't
|
||||
require the use of the `dapr` CLI and it integrates with the Spring Boot programming model.
|
||||
|
||||
You can find a [step-by-step tutorial showing this integration here](./spring-boot-examples/README.md).
|
||||
|
||||

# Dapr Spring Boot and Testcontainers integration Example
|
||||
|
||||
This example consists of two applications:
|
||||
- Producer App:
|
||||
- Publish messages using a Spring Messaging approach
|
||||
- Store and retrieve information using Spring Data CrudRepository
|
||||
- Implements a Workflow with Dapr Workflows
|
||||
- Consumer App:
|
||||
- Subscribe to messages
|
||||
|
||||
## Running these examples from source code
|
||||
|
||||
To run these examples you will need:
|
||||
- Java SDK
|
||||
- Maven
|
||||
- Docker or a container runtime such as Podman
|
||||
|
||||
From the `spring-boot-examples/` directory you can start each service using the test configuration that uses
|
||||
[Testcontainers](https://testcontainers.com) to boostrap [Dapr](https://dapr.io) by running the following command:
|
||||
|
||||
<!-- STEP
|
||||
name: Run Demo Producer Service
|
||||
match_order: none
|
||||
output_match_mode: substring
|
||||
expected_stdout_lines:
|
||||
- 'Started ProducerApplication'
|
||||
background: true
|
||||
expected_return_code: 143
|
||||
sleep: 30
|
||||
timeout_seconds: 45
|
||||
-->
|
||||
<!-- Timeout for above service must be more than sleep + timeout for the client-->
|
||||
|
||||
```sh
|
||||
cd producer-app/
|
||||
../../mvnw -Dspring-boot.run.arguments="--reuse=true" spring-boot:test-run
|
||||
```
|
||||
|
||||
<!-- END_STEP -->
|
||||
|
||||
This will start the `producer-app` with Dapr services and the infrastructure needed by the application to run,
|
||||
in this case RabbitMQ and PostgreSQL. The `producer-app` starts on port `8080` by default.
|
||||
|
||||
The `-Dspring-boot.run.arguments="--reuse=true"` flag helps the application to connect to an existing shared
|
||||
infrastructure if it already exists. For development purposes, and to connect both applications we will set the flag
|
||||
in both. For more details check the `DaprTestContainersConfig.java` classes in both, the `producer-app` and the `consumer-app`.
|
||||
|
||||
Then run in a different terminal:
|
||||
|
||||
<!-- STEP
|
||||
name: Run Demo Consumer Service
|
||||
match_order: none
|
||||
output_match_mode: substring
|
||||
expected_stdout_lines:
|
||||
- 'Started ConsumerApplication'
|
||||
background: true
|
||||
expected_return_code: 143
|
||||
sleep: 30
|
||||
timeout_seconds: 45
|
||||
-->
|
||||
<!-- Timeout for above service must be more than sleep + timeout for the client-->
|
||||
|
||||
```sh
|
||||
cd consumer-app/
|
||||
../../mvnw -Dspring-boot.run.arguments="--reuse=true" spring-boot:test-run
|
||||
```
|
||||
|
||||
<!-- END_STEP -->
|
||||
The `consumer-app` starts in port `8081` by default.
|
||||
|
||||
## Interacting with the applications
|
||||
|
||||
Now that both applications are up you can place an order by sending a POST request to `:8080/orders/`
|
||||
You can use `curl` to send a POST request to the `producer-app`:
|
||||
|
||||
|
||||
<!-- STEP
|
||||
name: Send POST request to Producer App
|
||||
match_order: none
|
||||
output_match_mode: substring
|
||||
expected_stdout_lines:
|
||||
- 'Order Stored and Event Published'
|
||||
background: true
|
||||
sleep: 1
|
||||
timeout_seconds: 2
|
||||
-->
|
||||
<!-- Timeout for above service must be more than sleep + timeout for the client-->
|
||||
|
||||
```sh
|
||||
curl -X POST localhost:8080/orders -H 'Content-Type: application/json' -d '{ "item": "the mars volta EP", "amount": 1 }'
|
||||
```
|
||||
|
||||
<!-- END_STEP -->
|
||||
|
||||
|
||||
If you check the `producer-app` logs you should see the following lines:
|
||||
|
||||
```bash
|
||||
...
|
||||
Storing Order: Order{id='null', item='the mars volta EP', amount=1}
|
||||
Publishing Order Event: Order{id='d4f8ea15-b774-441e-bcd2-7a4208a80bec', item='the mars volta EP', amount=1}
|
||||
|
||||
```
|
||||
|
||||
If you check the `consumer-app` logs you should see the following lines, showing that the message
|
||||
published by the `producer-app` was correctly consumed by the `consumer-app`:
|
||||
|
||||
```bash
|
||||
Order Event Received: Order{id='d4f8ea15-b774-441e-bcd2-7a4208a80bec', item='the mars volta EP', amount=1}
|
||||
```
|
||||
|
||||
Next, you can create a new customer to trigger the customer's tracking workflow:
|
||||
|
||||
<!-- STEP
|
||||
name: Start Customer Workflow
|
||||
match_order: none
|
||||
output_match_mode: substring
|
||||
expected_stdout_lines:
|
||||
- 'New Workflow Instance created for Customer'
|
||||
background: true
|
||||
sleep: 1
|
||||
timeout_seconds: 2
|
||||
-->
|
||||
<!-- Timeout for above service must be more than sleep + timeout for the client-->
|
||||
|
||||
```sh
|
||||
curl -X POST localhost:8080/customers -H 'Content-Type: application/json' -d '{ "customerName": "salaboy" }'
|
||||
```
|
||||
|
||||
<!-- END_STEP -->
|
||||
|
||||
|
||||
A new Workflow Instance was created to track the customers interactions. Now, the workflow instance
|
||||
is waiting for the customer to request a follow-up.
|
||||
|
||||
You should see in the `producer-app` logs:
|
||||
|
||||
```bash
|
||||
Workflow instance <Workflow Instance Id> started
|
||||
Let's register the customer: salaboy
|
||||
Customer: salaboy registered.
|
||||
Let's wait for the customer: salaboy to request a follow up.
|
||||
```
|
||||
|
||||
Send an event simulating the customer request for a follow-up:
|
||||
|
||||
<!-- STEP
|
||||
name: Emit Customer Follow-up event
|
||||
match_order: none
|
||||
output_match_mode: substring
|
||||
expected_stdout_lines:
|
||||
- 'Customer Follow-up requested'
|
||||
background: true
|
||||
sleep: 1
|
||||
timeout_seconds: 5
|
||||
-->
|
||||
<!-- Timeout for above service must be more than sleep + timeout for the client-->
|
||||
|
||||
```sh
|
||||
curl -X POST localhost:8080/customers/followup -H 'Content-Type: application/json' -d '{ "customerName": "salaboy" }'
|
||||
```
|
||||
|
||||
<!-- END_STEP -->
|
||||
|
||||
In the `producer-app` logs you should see that the workflow instance id moved forward to the Customer Follow Up activity:
|
||||
|
||||
```bash
|
||||
Customer follow-up requested: salaboy
|
||||
Let's book a follow up for the customer: salaboy
|
||||
Customer: salaboy follow-up done.
|
||||
Congratulations the customer: salaboy is happy!
|
||||
```
|
||||
|
||||
## Running on Kubernetes
|
||||
|
||||
You can run the same example on a Kubernetes cluster. [Check the Kubernetes tutorial here](kubernetes/README.md).

# Running this example on Kubernetes
|
||||
|
||||
To run this example on Kubernetes, you can use any Kubernetes distribution.
|
||||
We install Dapr on a Kubernetes cluster and then we will deploy both the `producer-app` and `consumer-app`.
|
||||
|
||||
## Creating a cluster and installing Dapr
|
||||
|
||||
If you don't have any Kubernetes cluster you can use Kubernetes KIND to create a local cluster. We will create a cluster
|
||||
with a local container registry, so we can push our container images to it. This is covered in the
|
||||
[KIND documentation here](https://kind.sigs.k8s.io/docs/user/local-registry/).
|
||||
|
||||
```bash
|
||||
./kind-with-registry.sh
|
||||
```
|
||||
|
||||
Once you have the cluster up and running you can install Dapr:
|
||||
|
||||
```bash
|
||||
helm repo add dapr https://dapr.github.io/helm-charts/
|
||||
helm repo update
|
||||
helm upgrade --install dapr dapr/dapr \
|
||||
--version=1.14.4 \
|
||||
--namespace dapr-system \
|
||||
--create-namespace \
|
||||
--wait
|
||||
```
|
||||
|
||||
## Creating containers using Spring Boot and pushing to local registry
|
||||
|
||||
Now that we have our cluster set up with a local container registry, we need to build our `producer-app` and `consumer-app` containers.
|
||||
For this we will use Spring Boot build it functions to create container images using [Buildpacks](https://buildpacks.io):
|
||||
|
||||
From inside the `spring-boot-examples/producer-app` directory you can run the following command to create a container:
|
||||
```bash
|
||||
mvn spring-boot:build-image
|
||||
```
|
||||
|
||||
Once we have the container image created, we need to tag and push to the local registry, so the image can be used from our local cluster.
|
||||
Alternatively, you can push the images to a public registry and update the Kubernetes manifests accordingly.
|
||||
|
||||
```bash
|
||||
docker tag producer-app:0.14.0-SNAPSHOT localhost:5001/sb-producer-app
|
||||
docker push localhost:5001/sb-producer-app
|
||||
```
|
||||
|
||||
From inside the `spring-boot-examples/consumer-app` directory you can run the following command to create a container:
|
||||
```bash
|
||||
mvn spring-boot:build-image
|
||||
```
|
||||
|
||||
Once we have the container image created, we need to tag and push to the local registry, so the image can be used from our local cluster.
|
||||
Alternatively, you can push the images to a public registry and update the Kubernetes manifests accordingly.
|
||||
|
||||
```bash
|
||||
docker tag consumer-app:0.14.0-SNAPSHOT localhost:5001/sb-consumer-app
|
||||
docker push localhost:5001/sb-consumer-app
|
||||
```
|
||||
|
||||
Now we are ready to install our application into the cluster.
|
||||
|
||||
## Installing and interacting with the application
|
||||
|
||||
Now that we have a running Kubernetes cluster, we need to first install the components needed by the application.
|
||||
In this case RabbitMQ and PostgreSQL. We will use Helm to do so:
|
||||
|
||||
Let's start with RabbitMQ:
|
||||
```bash
|
||||
helm install rabbitmq oci://registry-1.docker.io/bitnamicharts/rabbitmq --set auth.username=guest --set auth.password=guest --set auth.erlangCookie=ABC
|
||||
```
|
||||
|
||||
Then PostgreSQL:
|
||||
```bash
|
||||
helm install postgresql oci://registry-1.docker.io/bitnamicharts/postgresql --set global.postgresql.auth.database=dapr --set global.postgresql.auth.postgresPassword=password
|
||||
```
|
||||
|
||||
Once we have these components up and running we can install the application by running from inside
|
||||
the `spring-boot-examples/kubernetes/` directory:
|
||||
|
||||
```bash
|
||||
kubectl apply -f .
|
||||
```
|
||||
|
||||
Next you need to use `kubectl port-forward` to be able to send requests to the applications.
|
||||
|
||||
```bash
|
||||
kubectl port-forward svc/producer-app 8080:8080
|
||||
```
|
||||
|
||||
In a different terminals you can check the logs of the `producer-app` and `consumer-app`:
|
||||
|
||||
```bash
|
||||
kubectl logs -f producer-app-<POD_ID>
|
||||
```
|
||||
and
|
||||
|
||||
```bash
|
||||
kubectl logs -f consumer-app-<POD_ID>
|
||||
```

||||
