How to create an application
Every application which should be available on an Anbox Cloud cluster must be created first.
The internal process will prepare a container based on the currently available image with the application package installed. This container is then used for any newly launched containers to support fast boot times.
To create an application, you need an Android package (APK) with support for the target architecture. Additionally, you must select one of the available instance types for the application. The instance type defines CPU/RAM constraints put onto the container launch for the application.
See Instance types for a list of available instance types.
To create a new application, you must first create a manifest file to define the various attributes the new application should have. The manifest is a simple YAML file and looks like this:
name: candy instance-type: a4.3 image: default boot-activity: com.canonical.candy.GameApp required-permissions: - android.permission.WRITE_EXTERNAL_STORAGE - android.permission.READ_EXTERNAL_STORAGE addons: - ssh tags: - game extra-data: com.canonical.candy.obb: target: /data/app/com.canonical.candy-1/lib game-data-folder: target: /sdcard/Android/data/com.canonical.candy/ watchdog: disabled: false allowed-packages: - com.android.settings services: - name: adb port: 5559 protocols: [tcp] expose: false resources: memory: 4GB disk-size: 8GB
See Application manifest for detailed information about all available attributes.
Create from a directory
When creating an application from a directory, the directory should contain the required components for the creation:
Due to Snap strict confinement, the directory must be located in the home directory.
With everything in place, create the application by entering the following command:
amc application create <path/to/application-content>
create command returns, the application package is uploaded to the AMS service and the bootstrap process is started. The application is not yet ready to be used. You can watch the status of the application with the following command:
amc application show bcmap7u5nof07arqa2ag
The returned output looks similar to the following:
id: bcmap7u5nof07arqa2ag name: candy status: initializing published: false config: instance-type: a4.3 boot-package: com.canonical.candy versions: 0: image: bf7u4cqkv5sg5jd5b2k0 (version 0) published: false status: initializing addons: - ssh boot-activity: com.canonical.candy.GameApp required-permissions: - android.permission.WRITE_EXTERNAL_STORAGE - android.permission.READ_EXTERNAL_STORAGE extra-data: com.canonical.candy.obb: target: /data/app/com.canonical.candy-1/lib game-data-folder: target: /sdcard/Android/data/com.canonical.candy/ watchdog: disabled: false allowed-packages: - com.android.settings services: - port: 5559 protocols: - tcp expose: false name: adb resources: memory: 4GB disk-size: 8GB
Once the status of the application switches to
ready, the application is ready and can be used. See How to wait for an application for information about how to monitor the application status.
Create from a tarball
An application can also be created from a tarball file. The tarball file must be compressed with bzip2 and must use the same components and structure as the directory.
Due to Snap strict confinement, the tarball file must be located in the home directory.
For example, a tarball can be created with the following command:
tar cvjf foo.tar.bz2 -C <package-folder-path> app.apk extra-data manifest.yaml
Once the tarball is created, you can create the application:
amc application create foo.tar.bz2
The AMS service now starts the application bootstrap process. See How to wait for an application for information about how to monitor the application status.
