To create your Hub Executor, you just need to run:

jina hub new

For the basic configuration, you will be asked for two things: The Executor’s name and where it should be saved. A more advanced configuration is optional but rarely necessary.

After running the command, a project with the following structure will be generated:

├── Dockerfile	        # Advanced configuration will generate this file
├── manifest.yml
├── config.yml
├── requirements.txt
  • manifest.yml should contain the Executor’s annotations for getting better exposure on Jina Hub.

  • config.yml is the Executor’s configuration file, where you can define init arguments using with keyword.

  • requirements.txt describes the Executor’s Python dependencies.

  • should contain your Executor’s main logic.

  • should describe how to use your Executor.

Fields of manifest.yml#

manifest.yml is optional.

manifest.yml annotates your image so that it can be better managed by the Hub portal. To get better exposure on Jina Hub, you may want to carefully set manifest.yml to the correct values:

Key Description Default
manifest_version The version of the manifest protocol 1
name Human-readable title of the Executor None
description Human-readable description of the Executor None
url URL to find more information about the Executor, normally the GitHub repo URL None
keywords A list of strings to help users filter and locate your package None
