The documentation you are viewing is for Dapr v1.10 which is an older version of Dapr. For up-to-date documentation, see the latest version.

Quickstart: Input & Output Bindings

Get started with Dapr’s Binding building block

Let’s take a look at Dapr’s Bindings building block. Using bindings, you can:

Trigger your app with events coming in from external systems.
Interface with external systems.

In this Quickstart, you will schedule a batch script to run every 10 seconds using an input Cron binding. The script processes a JSON file and outputs data to a SQL database using the PostgreSQL Dapr binding.

Select your preferred language-specific Dapr SDK before proceeding with the Quickstart.

Pre-requisites

For this example, you will need:

Docker Desktop

Step 1: Set up the environment

Clone the sample provided in the Quickstarts repo.

git clone https://github.com/dapr/quickstarts.git

Step 2: Run PostgreSQL Docker container locally

Run the PostgreSQL instance locally in a Docker container on your machine. The Quickstart sample includes a Docker Compose file to locally customize, build, run, and initialize the postgres container with a default orders table.

In a terminal window, from the root of the Quickstarts clone directory, navigate to the bindings/db directory.

cd bindings/db

Run the following command to set up the container:

docker compose up

Verify that the container is running locally.

docker ps

The output should include:

CONTAINER ID   IMAGE      COMMAND                  CREATED         STATUS         PORTS                    NAMES
55305d1d378b   postgres   "docker-entrypoint.s…"   3 seconds ago   Up 2 seconds   0.0.0.0:5432->5432/tcp   sql_db

Step 3: Schedule a Cron job and write to the database

In a new terminal window, navigate to the SDK directory.

cd bindings/python/sdk/batch

Install the dependencies:

pip3 install -r requirements.txt

Run the batch-sdk service alongside a Dapr sidecar.

dapr run --app-id batch-sdk --app-port 50051 --resources-path ../../../components -- python3 app.py

Note: Since Python3.exe is not defined in Windows, you may need to use python app.py instead of python3 app.py.

The code inside the process_batch function is executed every 10 seconds (defined in binding-cron.yaml in the components directory). The binding trigger looks for a route called via HTTP POST in your application by the Dapr sidecar.

# Triggered by Dapr input binding
@app.route('/' + cron_binding_name, methods=['POST'])
def process_batch():

The batch-sdk service uses the PostgreSQL output binding defined in the binding-postgres.yaml component to insert the OrderId, Customer, and Price records into the orders table.

with DaprClient() as d:
    sqlCmd = ('insert into orders (orderid, customer, price) values ' +
              '(%s, \'%s\', %s)' % (order_line['orderid'],
                                    order_line['customer'],
                                    order_line['price']))
    payload = {'sql': sqlCmd}

    print(sqlCmd, flush=True)

    try:
        # Insert order using Dapr output binding via HTTP Post
        resp = d.invoke_binding(binding_name=sql_binding, operation='exec',
                                binding_metadata=payload, data='')
        return resp
    except Exception as e:
        print(e, flush=True)
        raise SystemExit(e)

Step 4: View the output of the job

Notice, as specified above, the code invokes the output binding with the OrderId, Customer, and Price as a payload.

Your output binding’s print statement output:

== APP == Processing batch..
== APP == insert into orders (orderid, customer, price) values (1, 'John Smith', 100.32)
== APP == insert into orders (orderid, customer, price) values (2, 'Jane Bond', 15.4)
== APP == insert into orders (orderid, customer, price) values (3, 'Tony James', 35.56)
== APP == Finished processing batch

In a new terminal, verify the same data has been inserted into the database. Navigate to the bindings/db directory.

cd bindings/db

Run the following to start the interactive Postgres CLI:

docker exec -i -t postgres psql --username postgres  -p 5432 -h localhost --no-password

At the admin=# prompt, change to the orders table:

\c orders;

At the orders=# prompt, select all rows:

select * from orders;

The output should look like this:

 orderid |  customer  | price
---------+------------+--------
       1 | John Smith | 100.32
       2 | Jane Bond  |   15.4
       3 | Tony James |  35.56

`components\binding-cron.yaml` component file

When you execute the dapr run command and specify the component path, the Dapr sidecar:

Initiates the Cron binding building block
Calls the binding endpoint (batch) every 10 seconds

The Cron binding-cron.yaml file included for this Quickstart contains the following:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: cron
  namespace: quickstarts
spec:
  type: bindings.cron
  version: v1
  metadata:
  - name: schedule
    value: "@every 10s" # valid cron schedule

Note: The metadata section of binding-cron.yaml contains a Cron expression that specifies how often the binding is invoked.

`component\binding-postgres.yaml` component file

When you execute the dapr run command and specify the component path, the Dapr sidecar:

Initiates the PostgreSQL binding building block
Connects to PostgreSQL using the settings specified in the binding-postgres.yaml file

With the binding-postgres.yaml component, you can easily swap out the backend database binding without making code changes.

The PostgreSQL binding-postgres.yaml file included for this Quickstart contains the following:

apiVersion: dapr.io/v1alpha1

  metadata:
  - name: url # Required
    value: "user=postgres password=docker host=localhost port=5432 dbname=orders pool_min_conns=1 pool_max_conns=10"

In the YAML file:

spec/type specifies that PostgreSQL is used for this binding.
spec/metadata defines the connection to the PostgreSQL instance used by the component.

Pre-requisites

For this example, you will need:

Docker Desktop

Step 1: Set up the environment

Clone the sample provided in the Quickstarts repo.

git clone https://github.com/dapr/quickstarts.git

Step 2: Run PostgreSQL Docker container locally

In a terminal window, from the root of the Quickstarts clone directory, navigate to the bindings/db directory.

cd bindings/db

Run the following command to set up the container:

docker compose up

Step 3: Schedule a Cron job and write to the database

In a new terminal window, navigate to the SDK directory.

cd bindings/javascript/sdk/batch

Install the dependencies:

npm install

Run the batch-sdk service alongside a Dapr sidecar.

dapr run --app-id batch-sdk --app-port 5002 --dapr-http-port 3500 --resources-path ../../../components -- node index.js

async function start() {
    await server.binding.receive(cronBindingName,processBatch);
    await server.start();
}

The batch-sdk service uses the PostgreSQL output binding defined in the binding-postgres.yaml component to insert the OrderId, Customer, and Price records into the orders table.

async function processBatch(){
    const loc = '../../orders.json';
    fs.readFile(loc, 'utf8', (err, data) => {
        const orders = JSON.parse(data).orders;
        orders.forEach(order => {
            let sqlCmd = `insert into orders (orderid, customer, price) values (${order.orderid}, '${order.customer}', ${order.price});`;
            let payload = `{  "sql": "${sqlCmd}" } `;
            console.log(payload);
            client.binding.send(postgresBindingName, "exec", "", JSON.parse(payload));
        });
        console.log('Finished processing batch');
      });
    return 0;
}

Step 4: View the output of the job

Notice, as specified above, the code invokes the output binding with the OrderId, Customer, and Price as a payload.

== APP == insert into orders (orderid, customer, price) values(2, 'Jane Bond', 15.4)
== APP == insert into orders (orderid, customer, price) values(3, 'Tony James', 35.56)

In a new terminal, verify the same data has been inserted into the database. Navigate to the bindings/db directory.

cd bindings/db

Run the following to start the interactive Postgres CLI:

docker exec -i -t postgres psql --username postgres  -p 5432 -h localhost --no-password

At the admin=# prompt, change to the orders table:
