NAME
    gcloud beta app gen-config - generate missing configuration files for a
        source directory

SYNOPSIS
    gcloud beta app gen-config [SOURCE_DIR] [--config=CONFIG] [--custom]
        [--runtime=RUNTIME] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (BETA) (DEPRECATED) This command is deprecated and will soon be removed.

    As an alternative, create an app.yaml file yourself using the directions at
    https://cloud.google.com/appengine/docs/flexible/reference/app-yaml (App
    Engine flexible environment) or
    https://cloud.google.com/appengine/docs/standard/reference/app-yaml (App
    Engine standard environment) under the tab for your language.

    To create a custom runtime, please follow the instructions at
    https://cloud.google.com/appengine/docs/flexible/custom-runtimes/

    This command generates all relevant config files (app.yaml, Dockerfile and
    a build Dockerfile) for your application in the current directory or emits
    an error message if the source directory contents are not recognized.

EXAMPLES
    To generate configs for the current directory:

        $ gcloud beta app gen-config

    To generate configs for ~/my_app:

        $ gcloud beta app gen-config ~/my_app

POSITIONAL ARGUMENTS
     [SOURCE_DIR]
        The source directory to fingerprint.

FLAGS
     --config=CONFIG
        The yaml file defining the service configuration. This is normally one
        of the generated files, but when generating a custom runtime there can
        be an app.yaml containing parameters.

     --custom
        If true, generate config files for a custom runtime. This will produce
        a Dockerfile, a .dockerignore file and an app.yaml (possibly other
        files as well, depending on the runtime).

     --runtime=RUNTIME
        Generate config files for a given runtime. Can be used in conjunction
        with --custom. Allowed runtimes are: contrib-dart, dart, go, php,
        php55, php72, python, python27, python-compat, java, java7, java8,
        nodejs, ruby, go111, go112.

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,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.

NOTES
    This command is currently in beta and might change without notice.
