| r"""LocalImageLocalInstance class. |
| |
| Create class that is responsible for creating a local instance AVD with a |
| local image. For launching multiple local instances under the same user, |
| The cuttlefish tool requires 3 variables: |
| - ANDROID_HOST_OUT: To locate the launch_cvd tool. |
| - HOME: To specify the temporary folder of launch_cvd. |
| - CUTTLEFISH_INSTANCE: To specify the instance id. |
| Acloud user must either set ANDROID_HOST_OUT or run acloud with --local-tool. |
| Acloud sets the other 2 variables for each local instance. |
| |
| The adb port and vnc port of local instance will be decided according to |
| instance id. The rule of adb port will be '6520 + [instance id] - 1' and the vnc |
| port will be '6444 + [instance id] - 1'. |
| e.g: |
| If instance id = 3 the adb port will be 6522 and vnc port will be 6446. |
| |
| To delete the local instance, we will call stop_cvd with the environment variable |
| [CUTTLEFISH_CONFIG_FILE] which is pointing to the runtime cuttlefish json. |
