1. Pre-instructions

The process of creating and deploying an application using Kubesphere is basically mastered in the previous steps.

PS: (an application with multiple components, such as FastAPI + Redis + PostresQL)

  • 1: Prepare the docker image of the service component required by the application
  • 2: Configure the environment variables required by some mirrors of the current service (configure the secret keys, etc.)
  • 3: Configure the PVC data mount volume of the service (mainly storage of static data of the service)
  • 4: Configure the extranet status based on the service status
  • 5: Identify the components of related services

Fastapi-hello World service foundation preparation

Service source: github.com/asdkant/fas…

2.1 Service Code

First we define a simple Hello World service: the code is as follows:

import fastapi

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def root():
    return {"message": "Hello World"}

Copy the code

2.2 Creating a Service Image Dockerfile

FROM tiangolo/ uvicorn-gunicorn-fastAPI :python3.7 COPY main.py /app/main.pyCopy the code

2.2 Uploading an image to DockerHub

Ps: The author himself has uploaded! Specific address:

Registry.hub.docker.com/r/asdkant/f…

If deployed using Docker can be directly:

docker pull asdkant/fastapi-hello-world

3. Start manual deployment

In fact, the deployment here is as simple as wordpress already deployed, or even less than that, mainly because our example does not need to mount external data storage, database dependencies, etc., so fade-out is just a simple service.

3.1 Building a self-made application

  • Log in to our Kubesphere using project-regular.

  • Enter the demo-project project we created last time:

  • Build your own app:

3.2 Setting Basic Application Information

Set the application name to fastapi-hello-world

3.3 Adding Service Components

Select the non-stateless service:

The service name is fastapi-hello-world

3.4 Adding a Mirror for a Service

Search for images: FastAPI

– Confirm port:

3.5 Ignore environment variables and mount storage

These are not needed when the mirror is started, so we can not configure!!

3.6 Advanced Settings – Enabling Internet access

3.7 Confirmation successful – No additional services need to be added!

3.8 Click To view application details and check the enabled port number

The port number is 30758

3.9 Access Verification

To access the address is: http://192.168.219.143:30758/

4. Dynamic operation service expansion

4.1 Entering the Corresponding Workload:

4.2 Select the service to view the workload and go to details

4.3 Adjustment of working copy

4.4 Configuring Elastic Service Scaling

Fill in the rules for elastic expansion:

5. View container logs

5.1 Select a Container in the Container Group:

5.2 Viewing Log Details:

At the end
