For local development and testing, you can run Pulsar in standalone mode on your own machine within a Docker container.

If you have not installed Docker, download it following [the instructions](https://docs.docker.com/get-docker/) for your OS.

## Start Pulsar in Docker

* For MacOS, Linux, and Windows:

  ```shell

  $ docker run -it -p 6650:6650  -p 8080:8080 --mount source=pulsardata,target=/pulsar/data --mount source=pulsarconf,target=/pulsar/conf apachepulsar/pulsar:@pulsar:version@ bin/pulsar standalone

  ```

A few things to note about this command:
 * The data, metadata, and configuration are persisted on Docker volumes in order to not start "fresh" every
time the container is restarted. For details on the volumes you can use `docker volume inspect <sourcename>`
 * For Docker on Windows make sure to configure it to use Linux containers

If you start Pulsar successfully, you will see `INFO`-level log messages like this:

```

08:18:30.970 [main] INFO  org.apache.pulsar.broker.web.WebService - HTTP Service started at http://0.0.0.0:8080
...
07:53:37.322 [main] INFO  org.apache.pulsar.broker.PulsarService - messaging service is ready, bootstrap service port = 8080, broker url= pulsar://localhost:6650, cluster=standalone, configs=org.apache.pulsar.broker.ServiceConfiguration@98b63c1
...

```

:::tip

When you start a local standalone cluster, a `public/default`

:::

namespace is created automatically. The namespace is used for development purposes. All Pulsar topics are managed within namespaces.
For more information, see [Topics](concepts-messaging.md#topics).

## Use Pulsar in Docker

Pulsar offers client libraries for [Java](pathname:///docs/client-libraries/java), [Go](pathname:///docs/client-libraries/go), [Python](pathname:///docs/client-libraries/python)
and [C++](pathname:///docs/client-libraries/cpp). If you're running a local standalone cluster, you can
use one of these root URLs to interact with your cluster:

* `pulsar://localhost:6650`
* `http://localhost:8080`

The following example will guide you get started with Pulsar quickly by using the [Python client API](pathname:///docs/client-libraries/python)
client API.

Install the Pulsar Python client library directly from [PyPI](https://pypi.org/project/pulsar-client/):

```shell

$ pip install pulsar-client

```

### Consume a message

Create a consumer and subscribe to the topic:

```python

import pulsar

client = pulsar.Client('pulsar://localhost:6650')
consumer = client.subscribe('my-topic',
                            subscription_name='my-sub')

while True:
    msg = consumer.receive()
    print("Received message: '%s'" % msg.data())
    consumer.acknowledge(msg)

client.close()

```

### Produce a message

Now start a producer to send some test messages:

```python

import pulsar

client = pulsar.Client('pulsar://localhost:6650')
producer = client.create_producer('my-topic')

for i in range(10):
    producer.send(('hello-pulsar-%d' % i).encode('utf-8'))

client.close()

```

## Get the topic statistics

In Pulsar, you can use REST, Java, or command-line tools to control every aspect of the system.
For details on APIs, refer to [Admin API Overview](admin-api-overview.md).

In the simplest example, you can use curl to probe the stats for a particular topic:

```shell

$ curl http://localhost:8080/admin/v2/persistent/public/default/my-topic/stats | python -m json.tool

```

The output is something like this:

```json
