（二）pulsar安装在独立的docker中，python测试
版本: 3.2.x
官网: https://pulsar.apache.org/docs/3.2.x/getting-started-docker/
安装pulasr服务
拉取镜像
# sudo docker pull apachepulsar/pulsar:3.0.3
sudo docker pull apachepulsar/pulsar:3.2.1
运行docker
CURRENT_DIR=$(cd `dirname $0`; pwd)
BASE_DIR=$(cd $(dirname $0);cd ..; pwd)FROM_DOCKER=apachepulsar/pulsar:3.2.1
DOCKER_NAME=pagoda_pulsar# 【新建要修改】主机端口

python简单测试
安装模块
pip install pulsar-client
例子参考：https://pulsar.apache.org/api/python/3.4.x/
（1）生产消息
import pulsarclient = 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()
（2）消费消息
import pulsarclient = pulsar.Client('pulsar://localhost:6650')
producer = client.create_producer('my-topic')for i in range(10):producer.send(('hello-pulsar-{i}').encode('utf-8'))client.close()
