Simplify deploying and managing Jina projects on Jina Cloud

Project description




JCloud logo: the command line interface that simplifies deploying and managing Jina projects on Jina Cloud


Simplify deploying and managing Jina projects on Jina Cloud

PyPI

☁️ To the cloud! - Smoothly deploy a local project as a cloud service. Radically easy, no brainfuck.

🎯 Cut to the chase - One CLI with five commands to manage the lifecycle of your Jina projects.

🎟️ Early free access - Sneak peek at our stealthy cloud hosting platform. Built on latest cloud-native tech stack, we now host your Jina project and offer computational and storage resources, for free!

Install

pip install jcloud
jc -h

In case jc is already occupied by another tool, please use jcloud instead. If your pip install doesn't register bash command for you, you can do python -m jcloud -h.

Get Started

Login

jc login

You can use Google/Github account to register and login. Without login, you can do nothing.

Deploy a Jina Project

In Jina's idiom, a project is a Flow, which represents an end-to-end task such as indexing, searching, recommending. In the sequel, we will use "project" and "Flow" interchangeably.

A Flow can have two types of file structure:

  • A folder: just like a regular Python project, you can have sub-folders of Executor implementations; and a flow.yml on the top-level to connect all Executors together. You can create an example project folder via jc new. This is often used in prototyping.
  • A single YAML file: a self-contained YAML file, consisting of all configs at the Flow-level and Executor-level. Note that, all Executors' uses: must follow uses: jinahub+docker://MyExecutor (from Jina Hub) or uses: docker://your_dockerhub_org/MyExecutor (from Docker Hub) to avoid any local file dependency. This is often used in production.

Deploy a Flow from a folder

jc new ./hello
jc deploy ./hello

Deploy a Flow from a single YAML

jc deploy toy.yml

The simplest toy.yml looks like the following:

jtype: Flow
executors: {}

A slightly complicated example, e.g. DALLE-mini (generating image from text prompt) looks like the following:

jtype: Flow
with:
  protocol: http
executors:
  - name: dalle_mini
    uses: jinahub+docker://DalleMini

Flow is succefully deployed when you see:

You will get a Flow ID, say 84b8b495df. This ID is required to manage, view logs and remove the Flow.

As this Flow is deployed with default gRPC gateway (feel free changing it to http or websocket), you can use jina.Client to access it:

from jina import Client, Document

c = Client(host='grpcs://84b8b495df.wolf.jina.ai')
print(c.post('/', Document(text='hello')))

View logs

To watch the logs in realtime.

jc logs 84b8b495df

Remove a Flow

jc remove 84b8b495df

Get the status of a Flow

jc status 84b8b495df

List all Flows on the cloud

jc list

You can only see the Flows deployed by you.

Verbose logs

To make the output more verbose, you can add --loglevel DEBUG before each CLI subcommand, e.g.

jc --loglevel DEBUG deploy toy.yml

gives you more comprehensive output.

FAQ

  • Why does it take a while on every operation of jcloud?

    Because the event listener at Jina Cloud is serveless by design, which means it spawns an instance on-demand to process your requests from jcloud. Note that operation such as deploy, remove in jcloud is not high-frequent. Hence, having a serveless listener is much more cost-efficient than an always-on listener. The downside is slower operations, nevertheless this does not affect the deployed service. Your deployed service is always on.

  • How long do you persist my service?

    Until you manually remove it, we will persist your service as long as possible.

  • Is everything free?

    Yes! We just need your feedback - use jc survey to help us understand your needs.

  • How powerful is Jina Cloud?

    Right now it is just m5.2xlarge. We are implementing auto-scaling of hosts on the server side. Also, it would be nice if you contact us on Slack or via jc survey to help us understand your needs.

  • How do I send request to a HTTP server?

    First, you need to set the Flow protocol to http. Then make sure you are sending to /post endpoint, e.g.

    curl -X POST https://6893976a58.wolf.jina.ai/post -H 'Content-Type: application/json' -d '{"data":[{"text": "hello, world!"}], "execEndpoint":"/"}'
