Commands

These are the commands that are available in UCC framework.

ucc-gen build

The ucc-gen build command builds the add-on. As of now, running ucc-gen does the same thing as running ucc-gen build, but eventually calling ucc-gen without specifying a subcommand will be deprecated.

It takes the following parameters:

  • --source - [optional] folder containing the app.manifest and app source. The default is package.
  • --config - [optional] path to the configuration file. It defaults to the globalConfig file in the parent directory of the source provided. Only .json and .yaml files are accepted.
  • --ta-version - [optional] override current version of TA. The default version is version specified in globalConfig.json or globalConfig.yaml. A Splunkbase compatible version of SEMVER is used by default.
  • -o / --output - [optional] output folder to store the build add-on. By default, it is saved in the current directory/output folder. Absolute paths are accepted as well.
  • --python-binary-name - [optional] Python binary name to use when installing Python libraries. The default is python3.
  • -v / --verbose - [optional] shows detailed information about created/copied/modified/conflict files after build is complete. This option is in the experimental mode. The default is False.
  • --pip-version - [optional] pip version that is used to install python libraries. The default is latest.
  • --pip-legacy-resolver - [optional] Use old pip dependency resolver by adding flag ‘–use-deprecated=legacy-resolver’ to pip install command. The default isFalse. >NOTE: This flag is deprecated and will be removed from pip in the future. Instead of using this flag, the correct solution would be to fix the packages your project depends on to work properly with the new resolver. Additionally, this flag is not compatible with pip version 23.2. Use 23.2.1 instead.

  • --pip-custom-flag - [optional] Additional flag(s) that will be added to the pip install command. By default, all the following flags are added to the pip install command: --no-compile, --prefer-binary and --ignore-installed. If --pip-custom-flag is specified these three arguments will be missing so if you still want them in your command add them to the --pip-custom-flag argument.

    Example: --pip-custom-flag="--no-compile --prefer-binary --ignore-installed --report path/to/report.json --progress-bar on"

  • --ui-source-map - [optional] if present generates front-end source maps (.js.map files), that helps with code debugging.

Verbose mode

The verbose mode is available for v5.35.0 and later.

Running ucc-gen build -v or ucc-gen build --verbose prints additional information about what was exactly created / copied / modified / conflicted after the build is complete. It does not scan the lib folder due to the nature of the folder.

See the following description of what each state means:

  • created: the file is not in the original package and was created during the build process.
  • copied: the file is in the original package and was copied during the build process.
  • modified: the file is in the original package and was modified during the build process.
  • conflict: the file is in the original package and was copied during the build process, but may be generated by UCC itself, so incorrect usage can stop the add-on from working.

ucc-gen init

ucc-gen init initializes the add-on. This is available on v5.19.0 and later. The ucc-gen init command initializes the add-on and bootstraps some code in the modular input which you, as a developer, can extend for your needs.

Apart from standard files needed for the add-on, it also adds search head clustering files in the default/server.conf file and reload triggers in the default/app.conf file. Those files will be soon generated automatically by the ucc-gen build command itself. during the add-on development.

It takes the following parameters:

  • --addon-name - [required] add-on name. See the official naming convention guide.
  • --addon-rest-root - [optional] add-on REST root, defaults to --addon-name if not provided.
  • --addon-display-name - [required] add-on “official” name.
  • --addon-input-name - [required] name of the generated input.
  • --addon-version - [optional] version of the generated add-on, with 0.0.1 by default.
  • --overwrite - [optional] overwrites the already existing folder. By default, you can’t generate a new add-on to an already existing folder.

ucc-gen import-from-aob

Import from AoB (Add-on Builder), from v5.24.0 and later. It is in the experimental state as of now, meaning that running this command may not produce a 100% UCC compatible add-on, but we are going to work on future improvements for the script itself.

Note: the import-from-aob command does not currently support Windows.

The import functionality is based on the ucc_migration_test bash script. One of the ways you can use it is to download an AoB-based add-on from Splunkbase, unarchive the folder, and then use ucc-gen import-from-aob --addon-name <unarchived-folder-name>. Or you can run the same command against your locally developed add-on, but it should be exported from AoB.

It accepts the following parameters:

  • --addon-name - [required] add-on name.

ucc-gen package

ucc-gen package can be used for v5.30.0 and later. It packages the add-on so it can be installed. It mimics the basics of the slim package command. This command can be used for most of the simple cases.

It does not support:

It accepts the following parameters:

  • --path - [required] path to the built add-on (should include the app.manifest file).
  • -o / --output - [optional] output folder to store the packaged add-on. By default, it will be saved in the current directory folder. It accepts absolute paths as well.
