## Procedure - When Deploying with Docker
|
|
|
|
### Get scheduler image
|
|
|
|
You can get it from [DockerHub](https://hub.docker.com/) directly.
|
|
|
|
1. Obtain the latest Docker image of the scheduler.
|
|
|
|
```sh
|
|
docker pull dragonflyoss/scheduler
|
|
```
|
|
|
|
Or you can build your own scheduler 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-scheduler D7Y_VERSION=$TAG
|
|
```
|
|
|
|
4. Obtain the latest Docker image ID of the scheduler.
|
|
|
|
```sh
|
|
docker image ls | grep 'scheduler' | awk '{print $3}' | head -n1
|
|
```
|
|
|
|
### Start scheduler
|
|
|
|
**NOTE:** Replace ${schedulerDockerImageId} with the ID obtained at the previous step.
|
|
|
|
```sh
|
|
docker run -d --name scheduler --restart=always -p 8002:8002 ${schedulerDockerImageId}
|
|
```
|
|
|
|
After scheduler is installed, run the following commands to verify if **scheduler** is started, and if Port `8002` is available.
|
|
|
|
```sh
|
|
telnet 127.0.0.1 8002
|
|
```
|
|
|
|
## Procedure - When Deploying with Physical Machines
|
|
|
|
### Get scheduler executable file
|
|
|
|
1. Download a binary package of the scheduler. You can download one of the latest builds for Dragonfly on the [github releases page](https://github.
|
|
com/dragonflyoss/Dragonfly2/releases).
|
|
|
|
```sh
|
|
version=2.0.0
|
|
wget https://github.com/dragonflyoss/Dragonfly2/releases/download/v$version/Dragonfly2_$version_linux_amd64.tar.gz
|
|
```
|
|
|
|
2. Unzip the package.
|
|
|
|
```bash
|
|
# Replace `xxx` with the installation directory.
|
|
tar -zxf Dragonfly2_2.0.0_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.
|
|
|
|
```sh
|
|
git clone https://github.com/dragonflyoss/Dragonfly2.git
|
|
```
|
|
|
|
2. Enter the project directory.
|
|
|
|
```sh
|
|
cd Dragonfly2
|
|
```
|
|
|
|
3. Compile the source code.
|
|
|
|
```sh
|
|
make build-scheduler && make install-scheduler
|
|
```
|
|
|
|
### Start scheduler
|
|
|
|
```sh
|
|
scheduler --options
|
|
```
|
|
|
|
After scheduler is installed, run the following commands to verify if **scheduler** is started, and if Port `8002` is available.
|
|
|
|
```sh
|
|
telnet 127.0.0.1 8002
|
|
```
