Named arguments#

Named arguments are intended for detailed configuration of all commands for the luna_prepare script.

Each command has a specific set of named arguments available. A list of named arguments for each command can be obtained using the reference argument:

docker run \
--rm \
--network=host \
dockerhub.visionlabs.ru/luna/storages:v.0.4.23 \
bash -c "luna_prepare <command> <named_argument> --help"

If the prepare command is used, then named arguments are specified after positional ones (see "Types of passed arguments" section).

The table below provides a description for all named arguments.

* to get the Storages utility settings, you can use either the --config argument or the --luna-config argument. See "Setting Storages configuration" for details.

** latest revision does not always mean a revision for the latest version of LUNA PLATFORM. If you need a revision of the latest version of LP, then you don’t have to specify the --configs-revision flag, because the default value means using the revision corresponding to the LUNA PLATFORM version specified in the --platform_version flag.

*** named arguments can be used in the case when you need to create a database from one user and use it from another.

Also, when using the --luna-config argument, you can pass the following named arguments containing the configuration tag in the Configurator service:

  • --LUNA_LAMBDA_DB
  • --LUNA_FACES_DB
  • --LUNA_BACKPORT3_DB
  • --LUNA_ACCOUNTS_DB
