Installing Dragonfly Scheduler Server

This topic explains how to install the Dragonfly scheduler server.

Context

Install scheduler in one of the following ways:

• Deploying with Docker: Recommended for production usage.
• Deploying with physical machines.

Prerequisites

When deploying with Docker, the following conditions must be met.

Required Software	Version Limit
Git	1.9.1+
Docker	1.12.0+

When deploying with physical machines, the following conditions must be met.

Required Software	Version Limit
Git	1.9.1+
Golang	1.12.x
Nginx	0.8+

Procedure - When Deploying with Docker

Get scheduler image

You can get it from DockerHub directly.

1. Obtain the latest Docker image of the scheduler.

   docker pull d7yio/scheduler
   

Or you can build your own scheduler image.

1. Obtain the source code of Dragonfly.

   git clone https://github.com/dragonflyoss/Dragonfly2.git
   

2. Enter the project directory.

   cd Dragonfly2
   

3. Build the Docker image.

   TAG="1.0.0"
   make docker-build-scheduler D7Y_VERSION=$TAG
   

4. Obtain the latest Docker image ID of the scheduler.

   docker image ls | grep 'scheduler' | awk '{print $3}' | head -n1
   

Start scheduler

NOTE: Replace ${schedulerDockerImageId} with the ID obtained at the previous step.

docker run -d --name scheduler --restart=always -p 8002  ${schedulerDockerImageId}

Procedure - When Deploying with Physical Machines

Get scheduler executable file

1. Download a binary package of the scheduler. You can download one of the latest builds for Dragonfly on the [github releases page](https://github. com/dragonflyoss/Dragonfly2/releases).

   version=1.0.0
   wget https://github.com/dragonflyoss/Dragonfly2/releases/download/v$version/Dragonfly2_$version_linux_amd64.tar.gz
   

2. Unzip the package.

   # Replace `xxx` with the installation directory.
   tar -zxf Dragonfly2_1.0.0_linux_amd64.tar.gz -C xxx
   

3. Move the scheduler to your PATH environment variable to make sure you can directly use scheduler command.

Or you can build your own scheduler executable file.

1. Obtain the source code of Dragonfly.

   git clone https://github.com/dragonflyoss/Dragonfly2.git
   

2. Enter the project directory.

   cd Dragonfly2
   

3. Compile the source code.

   make build-scheduler && make install-scheduler
   

Start scheduler

scheduler --options

After this Task

• After scheduler is installed, run the following commands to verify if scheduler is started, and if Port 8002 is available.

  telnet 127.0.0.1 8002
