Usage

Integrate Metaplay SDK to Your Game

You can add Metaplay SDK to your game using the integration wizard in the CLI by running:

MyProject$ metaplay init project

This will link your local project to the Metaplay Portal, donwload and extract the SDK, add the game-specific backend project, and add some samples on how to get started.

Build and Deploy Server to Cloud

You must run the steps in the same directory as your metaplay-project.yaml project config file is located.

First, build the game server docker image.

MyProject$ metaplay build image <image>:<tag>

Then, deploy the game server to an environment:

MyProject$ metaplay deploy server <environment> <image>:<tag>

The command also pushes the docker image to the environment's registry.

View Game Server Logs

To get logs from your game server running in the cloud, use the following:

metaplay debug logs ENVIRONMENT

By default, it shows time-ordered logs from all pods, but you can also only target a single pod with:

metaplay debug logs ENVIRONMENT --pod=POD_NAME

It's enough to provide only the environment ID's suffix. For example, in project lovely-wombats-build, the environment lovely-wombats-build-quickly can be targeted with just:

metaplay debug logs quickly

Alternatively, you can run the command without any parameters and the CLI will ask you the project and environment:

metaplay debug logs

Kubernetes Access

To access the Kubernetes control plane for your environment, you can do the following:

# Get the kubeconfig file for the environment.
metaplay get kubeconfig ENVIRONMENT -o <pathToKubeconfig>
# Configure kubectl to use the kubeconfig file.
export KUBECONFIG=<pathToKubeconfig>
# Check the status of your pods.
kubectl get pods

By default, the generated kubeconfig file will invoke the metaplay CLI itself to resolve the credentials used to communicate with the Kubernetes control plane.

Using in CI Jobs

Tips & Tricks

Working Directory

It's generally easiest to run the metaplay CLI in your project directory, i.e., where metaplay-project.yaml is located. This way the CLI knows the project you're working with and can target operations to operate on that.

If you wish to run in another directory, provide the path to the project directory with -p <pathToProject>.

Troubleshooting the CLI

If you have any issues running a command, give it the --verbose flag to get more detailed output on what is happening, e.g.:

metaplay deploy server <environment> <image>:<tag> --verbose

Multiple Sessions

The CLI supports storing multiple sessions at the same time. This can be useful when working with projects that use 3rd party authentication instead of Metaplay Portal for their authentication.

The authentication provider is determined from the metaplay-project.yaml and thus any authentication operations are dependent on the project in the context of which the CLI is run.

Support & Feature Requests

If you have a paid support contract with Metaplay, you can open a ticket on the Metaplay portal's support page.

Development

If you develop the CLI or the Metaplay platform, see DEVELOPMENT.md for building and testing the CLI, for development builds and update channels, and for running it against a local or test environment.
