py_az_vm_controller

Introduction

This is simple library for doing remote turn on and off azure virtual machine.

The library requires the user to have

• Azure Subscription with Entra ID (Entra ID's app id as tenantID) for register new app (registered app) for oauth login
  • App ID as clientId
  • Creating Credential as (clientSecret)
• The registered app configured to be able to perform
  • Microsoft.Compute/virtualMachines/read
  • Microsoft.Compute/virtualMachines/instanceView/read
  • Microsoft.Compute/virtualMachines/start/action
  • Microsoft.Compute/virtualMachines/powerOff/action

Execution

This is a library rather then a executable problem. The execution will trigger the demo only

Run through python interpreter:

python -m py_az_vm_controller

Demo Code

import os
os.environ["using-j-vault-rest-server"]="localhost,7910,false,harden"
import py_az_vm_controller as project
from j_vault_http_client_xethhung12 import client

# Make sure you defined the system variables:
#     * tenantId              <--- The microsoft Entra Id
#     * clientId              <--- The client id of the app registered
#     * clientSecret          <--- The client secret of the app registered 
#     * subscriptionId        <--- The subscription id of the VM
#     * resourceGroupName     <--- The resource group name of the VM
#     * vmName                <--- The name of the virtual machine

import time
def main():
    client.load_to_env()
    tenantId = os.getenv("tenantId")
    clientId = os.getenv("clientId")
    clientSecret = os.getenv("clientSecret")
    subscriptionId = os.getenv("subscriptionId")
    resourceGroupName = os.getenv("resourceGroupName")
    vmName = os.getenv("vmName")
    print(tenantId, clientId, clientSecret, subscriptionId, resourceGroupName, vmName)
    azOAuth = project.AzOAuth(tenantId)
    session = azOAuth.get_session(clientId, clientSecret)
    vm = session.vm(subscriptionId, resourceGroupName, vmName)
    if vm.isVMStopped():
        print("Try power on the machine")
        vm.powerOn()
    while(True):
        time.sleep(5)
        print(vm.instanceState())
        if vm.isVMRunning():
            print("running finally")
            break
        
    time.sleep(10)

    print("stopping machine")
    vm.powerOff()
    while(True):
        time.sleep(5)
        print(vm.instanceState())
        if vm.isVMStopped():
            print("stopped finally")
            break

Development

The project requires python (3+ version) installed and pip ready for use on adding manage dependencies

Tools

• install-dependencies.sh The script will install dependencies listed in dev-requirements.txt and requirements.txt. The first requirement file contains the dependencies for development like build and deploy tools. The second requirement file defined all required dependencies for the making the package works (actual dependencies).

Useful Scripts

Project Versioning

For version update in pyproject.toml. This project use package xh-py-project-versioning to manipulate the project version.

Simple usage includes:
Base on current version, update the patch number with dev id python -m xh_py_project_versioning --patch
In case current version is 0.0.1, the updated version will be 0.0.2-dev+000

To prompt the dev version to official version use command. python -m xh_py_project_versioning -r. Through the command, version 0.0.2-dev+000 will be prompt to 0.0.2 official versioning.

Base on current version, update the patch number directly python -m xh_py_project_versioning --patch -d
In case current version is 0.0.1, the updated version will be 0.0.2

Base on current version, update the minor number directly python -m xh_py_project_versioning --minor -d
In case current version is 0.0.1, the updated version will be 0.1.0

Base on current version, update the minor number directly python -m xh_py_project_versioning --minor -d
In case current version is 0.0.1, the updated version will be 1.0.0
