Procedure - When Deploying with Docker

Get dfdaemon image

You can get it from DockerHub directly.

Or you can build your own dfdaemon image.

  1. Obtain the source code of Dragonfly.
git clone https://github.com/dragonflyoss/Dragonfly2.git
  1. Enter the project directory.
cd Dragonfly2
  1. Build the Docker image.
TAG="2.0.0"
make docker-build-dfdaemon D7Y_VERSION=$TAG
  1. Obtain the latest Docker image ID of the dfdaemon.
docker image ls | grep 'dfdaemon' | awk '{print $3}' | head -n1

Start dfdaemon

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

docker run -d --name dfdaemon --restart=always -p 65000:65000 -p 65001:65001 -p 65002:65002 ${dfdaemonDockerImageId} daemon

After dfget is installed, run the following commands to verify if dfdaemon is started, and if Port 65000, 65001 and 65002 is available.

telnet 127.0.0.1 65000
