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 dragonflyoss/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="2.0.0"
   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 8002:8002 ${schedulerDockerImageId}

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
