NAME
    gcloud app instances enable-debug - enable debug mode for an instance
        (only works on the flexible environment)

SYNOPSIS
    gcloud app instances enable-debug [INSTANCE]
        [--service=SERVICE, -s SERVICE] [--version=VERSION, -v VERSION]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    When in debug mode, SSH will be enabled on the VMs, and you can use gcloud
    compute ssh to login to them. They will be removed from the health checking
    pools, but they still receive requests.

    Note that any local changes to an instance will be lost if debug mode is
    disabled on the instance. New instance(s) may spawn depending on the app's
    scaling settings.

    Additionally, debug mode doesn't work for applications using the App Engine
    standard environment.

EXAMPLES
    To enable debug mode for a particular instance, run:

        $ gcloud app instances enable-debug --service=s1 --version=v1 i1

    To enable debug mode for an instance chosen interactively, run:

        $ gcloud app instances enable-debug

POSITIONAL ARGUMENTS
     [INSTANCE]
        Instance ID to enable debug mode on. If not specified, select instance
        interactively. Must uniquely specify (with other flags) exactly one
        instance

FLAGS
     --service=SERVICE, -s SERVICE
        If specified, only match instances belonging to the given service. This
        affects both interactive and non-interactive selection.

     --version=VERSION, -v VERSION
        If specified, only match instances belonging to the given version. This
        affects both interactive and non-interactive selection.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
