| 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. |
| The user can optionally specify the folder by --local-instance-dir and the |
| instance id by --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. |
| |
| To run this program outside of a build environment, the following setup is |
| required. |
| - One of the local tool directories is a decompressed cvd host package, |
| i.e., cvd-host_package.tar.gz. |
| - If the instance doesn't require mixed images, the local image directory |
| should be an unzipped update package, i.e., <target>-img-<build>.zip, |
| which contains a super image. |
| - If the instance requires mixing system image, the local image directory |
| should be an unzipped target files package, i.e., |
| <target>-target_files-<build>.zip, |
| which contains misc info and images not packed into a super image. |
| - If the instance requires mixing system image, one of the local tool |
| directories should be an unzipped OTA tools package, i.e., otatools.zip. |
