Apache Pulsar manager

Apache Pulsar manager is a web-based GUI management tool for managing and monitoring Pulsar.

A Pulsar Manager is capable of managing multiple Pulsar clusters. A Pulsar instance or a group of Pulsar clusters is defined as an Environment in Pulsar Manager. You can create as many environments as you can. The following diagram illustrates the overall architecture of a Pulsar Manager.

A running Pulsar Manager instance is comprised of two components: one is the frontend which provides the GUI to manage and monitor Pulsar clusters, the other one is the backend which interacts with Pulsar clusters for collecting metrics, forwarding admin requests to the requested Pulsar cluster or brokers.

Since Pulsar Manager directly interacts with Pulsar brokers and bookies for management, it is required to deploy the Pulsar Manager into the same network as your Pulsar clusters. So the Pulsar Manager backend is able to talk to the brokers and bookies in your Pulsar cluster.

Install

Use Docker

1. Start Pulsar standalone.

   docker pull apachepulsar/pulsar:latest
   docker run -d -it \
       -p 6650:6650 \
       -p 8080:8080 \
       -v pulsardata:/pulsar/data \
       -v pulsarconf:/pulsar/conf \
       --name pulsar-standalone \
       apachepulsar/pulsar:latest \
       bin/pulsar standalone
   

2. Start Pulsar Manager in a separate container.

NOTE: the command links the pulsar-manager container with the pulsar standalone container so they are in the same network.

```
docker pull apachepulsar/pulsar-manager:v0.1.0
docker run -it \
    -p 9527:9527 \
    -e REDIRECT_HOST=127.0.0.1 \
    -e REDIRECT_PORT=9527 \
    -e DRIVER_CLASS_NAME=org.postgresql.Driver \
    -e URL='jdbc:postgresql://127.0.0.1:5432/pulsar_manager' \
    -e USERNAME=pulsar \
    -e PASSWORD=pulsar \
    -e LOG_LEVEL=DEBUG \
    -v pulsarui:/data \
    --link pulsar-standalone \
    apachepulsar/pulsar-manager:v0.1.0
```

* `REDIRECT_HOST`: the IP address of the front-end server.
    
* `REDIRECT_PORT`: the port of the front-end server.

* `DRIVER_CLASS_NAME`: the driver class name of PostgreSQL.

* `URL`: the jdbc url of your PostgreSQL database, example: jdbc:postgresql://127.0.0.1:5432/pulsar_manager. The docker image automatically start a local instance of PostgresSQL database.

* `USERNAME`: the username of PostgreSQL.

* `PASSWORD`: the password of PostgreSQL.

* `LOG_LEVEL`: level of log.

* `pulsarui`: docker volume to store PostgresSQL data.

Use Docker Compose

Alternatively, you can start a standalone and Pulsar Manager using the docker compose file provided in this repository.

1. Clone this git repoistory.

   https://github.com/apache/pulsar-manager

2. Go to the docker directory.

   cd docker

3. Start the docker composed cluster.

   docker-compose up

Deploy Pulsar Manager to Kubernetes

The Pulsar Manager can be deployed as part of Pulsar Helm Chart.

1. Install the Pulsar cluster with Pulsar Manager

   helm repo add streamnative https://charts.streamnative.io
   helm repo update
   helm install <release-name> streamnative/pulsar

2. Access the Pulsar Manager.

   The default values will create a ClusterIP for the Pulsar Manager you can use to interact with cluster. To find the IP address of the Pulsar Manager, use the following command:

   kubectl get service -n <k8s-namespace>

   After find the ip address of the Pulsar Manager, you can access the Pulsar Manager at http://${pulsar-manager-cluster-ip}/#/environments.

Build from source code

Prerequisites

• Java JDK 1.8
• Node 10.15.3 or later
• Npm 6.4.1 or later
• Pulsar 2.4.0 or later

Build instructions

1. Clone the source code.

   git clone https://github.com/apache/pulsar-manager

2. Build and start the backend.

   cd pulsar-manager
   ./gradlew build -x test
   cd build/distributions
   unzip pulsar-manager.zip or tar -zxvf pulsar-manager.tar
   ./pulsar-manager/bin/pulsar-manager
   

3. Open a new terminal, build and start the front end.

   cd pulsar-manager/front-end
   npm install --save
   npm run dev
   

After running these steps, the Pulsar Manager is running locally at http://127.0.0.1/#/environments.

Access Pusar Manager

1. Access Pulsar manager UI at http://${frontend-end-ip}/#/environments.

If you started Pulsar Manager using docker or docker-compose, the Pulsar Manager is running at port 9527. You can access the Pulsar Manager UI at http://127.0.0.1/#/environments.

If you are deploying Pulsar Manager 0.1.0 using the released container, you can log in the Pulsar Manager UI using the following credentials.

• Account: pulsar
• Password: pulsar

If you are deploying Pulsar Manager using the latest code, you can create a super-user using the following command. Then you can use the super user credentials to log in the Pulsar Manager UI.

```$xslt
curl 
    -H "Content-Type: application/json" \
    -X PUT http://backend-service:7750/pulsar-manager/users/superuser \
    -d '{"name": "admin", "password": "apachepulsar", "description": "test", "email": "username@test.org"}'
```

backend-service: The IP address or domain name of the backend service.

2. Create an environment.

   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 the service url that Pulsar Manager is able to access. In this example, both pulsar container and pulsar-manager container are linked. So you can use pulsar container name as the domain name of the pulsar standalone cluster. Thus you can type http://pulsar-standalone:8080.

Development

Default Test database HerdDB

Introduction

Pulsar Manager bundles JDBC Drivers for HerdDB. The default configuration starts and embedded in-memory only HerdDB database.

HerdDB can be used in production, you just have to use the correct JDBC URL. Follow the instructions in application.properties to switch the connection to a standalone HerdDB service or cluster.

The JDBC URL will look like this: jdbc:herddb:server:localhost:7000

In cluster mode HerdDB uses Apache BookKeeper and Apache ZooKeeper to store data and metadata, you can share your ZooKeeper cluster and the Bookies bundled with Pulsar.

The JDBC URL will look like this: jdbc:herddb:zookeeper:localhost:2181/herddb

In order to start and setup an HerdDB database follow the instructions on the HerdDB documentation.
