# Installing Dragonfly Manager Server

This topic explains how to install the Dragonfly manager server.

## Prerequisites

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

| Required Software | Version Limit |
| ----------------- | ------------- |
| Git               | 1.9.1+        |
| Docker            | 1.12.0+       |

## Procedure - When Deploying with Docker

### Get manager image

You can get it from [DockerHub](https://hub.docker.com/) directly.

1. Obtain the latest Docker image of the manager.

   ```sh
   docker pull dragonflyoss/manager
   ```

Or you can build your own manager image.

1. Obtain the source code of Dragonfly.

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

2. Enter the project directory.

   ```sh
   cd Dragonfly2
   ```

3. Build the Docker image.

   ```sh
   TAG="2.0.0"
   make docker-build-manager D7Y_VERSION=$TAG
   ```

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

   ```sh
   docker image ls | grep 'manager' | awk '{print $3}' | head -n1
   ```

### Start manager

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

```sh
docker run -d --name manager --restart=always -p 8080:8080 -p 65003:65003 ${managerDockerImageId}
```

After manager is installed, run the following commands to
verify if **manager** is started, and if Port `8080` and `65003` is available.

```sh
telnet 127.0.0.1 8080
telnet 127.0.0.1 65003
```

### Manager console

Now you can open brower and visit [console](http://localhost:8080)
