Ensure you have allocated enough memory to Docker: at least 8Gb.
On Macs with ARM chip, enabling Rosetta for amd64 emulation on Docker will make your containers boot faster.
Before jumping into any of the scenarios, you must start the shared infrastructure all of them will use. This includes one Zookeeper instance, two Bookkeepers, and two Pulsar brokers.
1οΈβ£ Start the persistence layer
sh start-persistence.sh
π You must wait until the containers zookeeper
, persistence-bookie-1
, and persistence-bookie-2
are healthy to proceed with the next step.
2οΈβ£ Start the Pulsar brokers with AoP, KoP, and MoP enabled
sh start-brokers.sh
π You must wait until the container broker-1
is healthy to proceed with any next step.
3οΈβ£ Optional: Start the control plane
sh start-control-plane.sh
π You must wait until the container pulsar-manager
is healthy before you can access the UI and create an environment. Once the container is running, you should see a screen similar to the following when you visit http://localhost:9527. Enter admin
for the username and apachepulsar
as the password.
Next, you will need to add an environment to the Pulsar Manager. An environment represents a Pulsar instance or a group of clusters you want to manage. A Pulsar Manager is capable of managing multiple environments.
Click "New Environment" button to add an environment.
Input the "Environment Name". The environment name is used for identifying an environment.
Input the "Service URL". The Service URL is the admin service url of your Pulsar cluster.
You need to make sure that Pulsar Manager is able to access the service url. In this example, both the pulsar container and pulsar-manager container use the same docker network. So you can use pulsar container name as the domain name of the pulsar standalone cluster. Thus, you can type http://broker-1:8080 in the service URL box and click on the confirm
button.
This will create the environment and allow you to manage the Pulsar cluster from the Pulsar Manager UI.
This scenario checks two things. First, if AoP provides a truly AMQP-compatible API where third-party frameworks such as Spring Boot can connect with without deployment problems. Second, to check whether we can both send and receive messages using the AMQP protocol using Pulsar. 1οΈβ£ Run the Spring Boot microservice
sh microservice-with-amqp/run-microservice.sh
π You must wait until the microservice connects with the brokers and start producing and consuming messages like this:
i.s.protocols.amqp.demo.MyAmqpListener : Received [π° - I am using AMQP to talk to Pulsar - 1]
2οΈβ£ stop the microservice using Ctrl+C.
This scenario checks two things. First, if Pulsar provides a truly JMS-compatible API where third-party frameworks such as Spring Boot can connect with without deployment problems. Second, to check whether we can both send and receive messages with the JMS protocol using Pulsar. 1οΈβ£ Run the Spring Boot microservice
sh microservice-with-jms/run-microservice.sh
π You must wait until the microservice connects with the brokers and start producing and consuming messages like this:
i.s.protocols.jms.demo.MyJmsListener : Received [π¦οΈ - I am using JMS to talk to Pulsar - 1]
i.s.protocols.jms.demo.MyJmsListener : Received [π¦οΈ - I am using JMS to talk to Pulsar - 2]
i.s.protocols.jms.demo.MyJmsListener : Received [π¦οΈ - I am using JMS to talk to Pulsar - 3]
i.s.protocols.jms.demo.MyJmsListener : Received [π¦οΈ - I am using JMS to talk to Pulsar - 4]
2οΈβ£ stop the microservice using Ctrl+C.
This scenario checks two things. First, if KoP provides a truly Kafka-compatible API where third-party frameworks such as Spring Boot can connect with without deployment problems. Second, to check whether we can both send and receive messages using the Kafka protocol using Pulsar. 1οΈβ£ Run the Spring Boot microservice
sh microservice-with-kafka/run-microservice.sh
π You must wait until the microservice connects with the brokers and start producing and consuming messages like this:
i.s.p.kafka.demo.MyKafkaListener : Received [πΆ - I am using Kafka to talk to Pulsar - 1]
2οΈβ£ stop the microservice using Ctrl+C.
This scenario checks two things. First, if MoP provides a truly MQTT-compatible API where third-party frameworks such as Spring Boot can connect with without deployment problems. Second, to check whether we can both send and receive messages using the MQTT protocol using Pulsar. 1οΈβ£ Run the Spring Boot microservice
sh microservice-with-mqtt/run-microservice.sh
π You must wait until the microservice connects with the brokers and start producing and consuming messages like this:
i.s.p.mqtt.demo.MqttMessageListener : Received [π± - I am using MQTT to talk to Pulsar - 1]
2οΈβ£ stop the microservice if you're done for the day using Ctrl+C.
This scenario tests the Pulsar integration with the Spring Boot frameworks. Can we connect with without deployment problems as well as send and receive messages using the spring-pulsar-spring-boot-starter
.
1οΈβ£ Run the Spring Boot microservice
sh microservice-with-pulsar/run-microservice.sh
π You must wait until the microservice connects with the brokers and start producing and consuming messages like this:
i.s.p.pulsar.demo.MyPulsarListener : Received [π¦ - I am using Pulsar to talk to Pulsar - 1]
2οΈβ£ stop the microservice if you're done for the day using Ctrl+C.
This scenario tests if clients using different messaging protocols (AoP, MoP, KoP, and Native Pulsar) can exchange messages on a single common topic.
1οΈβ£ Run the Spring Boot Aop microservice
sh microservice-with-amqp/run-microservice.sh
π The console for the AMQP microservice shows that it only ever consumes messages published using the AMQP protocol:

2οΈβ£ In another console window, start the Spring Boot MoP microservice
sh microservice-with-mqtt/run-microservice.sh
3οΈβ£ In another console window, start the Spring Boot Kafka microservice
sh microservice-with-kafka/run-microservice.sh
4οΈβ£ Finally, in another console window, start the Spring Boot Pulsar microservice
sh microservice-with-pulsar/run-microservice.sh
π Observe the fact that messages from different protocols are getting received by the MoP, KoP, and Pulsar microservices:

Pretty cool, huh?
When you are finished with your testing, you can stop all docker containers using the following command:
sh stop-everything.sh
