Azure CLI

• Azure CLI Refer Here
• Azure CLI Onboarding Guide
• login into azure cli az login
• Azure CLI Command structure

az <service-group> [sub-groups] <action> [args]

• Examples

az group create
az sql server create
az vm list
az group delete

• azure cli also gives the responses in json form by default
• We can filter the responses using jmes path

az group list --query ""

• Finding documentation:
  • Google azure <> cli or azure <> quick start

Lets create an Azure Virtual machine

• inputs:
• resource group:
  • name
  • location
• name: hello-cli
• location: eastus
• size: Standard_B1s
• Image: ubuntu 24.04
• credentials:
  • username
  • password/key
• ports or nsg
• output: virtual machine with public ip
• Steps:
  • create a resource group
  • create a vm

#!/bin/bash
group_name='fromcli'
location='eastus'
vm_name='node-1'


# if resource group does not exist create one
if [ $(az group exists --name $group_name) = false ]; then 
   az group create --name ${group_name} --location ${location}

     az vm list --output tsv | grep $vm_name -q || az vm create --name ${vm_name} \
        --resource-group ${group_name} \
        --authentication-type 'password' \
        --admin-username 'qtdevops' \
        --admin-password 'ltdevops@123' \
        --nsg-rule 'SSH' \
        --size 'Standard_B1s' \
        --image 'Ubuntu2404' \
        --zone 1
else
   echo $resourceGroup
fi

Lets create reusable scripts in AWS and Azure using CLI

Manage start, stop and terminate of ec2 instances

• inputs:
  • instance-id
  • region
  • action: start | stop | terminate
• solution

#!/bin/bash
#
# Controls start stop and terminating the ec2 instance
# usage:
#  ./ec2_control.sh <action> <instance-id> <region>
#      action = [start|stop|termination]
# author: khaja
#

action=$1
instance_id=$2
region=$3

if [[ $action == "start"  ]]; then
    # if action is start
    aws ec2 start-instances --instance-ids ${instance_id} --region ${region}
    echo "performed action: ${action} on instance-id ${instance_id}"
elif [[ $action == "stop"  ]]; then
    # if action is stop
    aws ec2 stop-instances --instance-ids ${instance_id} --region ${region}
    echo "performed action: ${action} on instance-id ${instance_id}"
elif [[ $action == "terminate"  ]]; then
    # if action is terminate
    aws ec2 terminate-instances --instance-ids ${instance_id} --region ${region}
    echo "performed action: ${action} on instance-id ${instance_id}"
else 
    echo "Wrong usage: Not a valid action"
    echo "./ec2_control.sh <action> <instance-id> <region>"
    echo "action = [start|stop|termination]"
    exit 1
fi

# command="${action}-instances"
# aws ec2 ${command} --instance-ids ${instance_id} --region ${region}

• Write me something similar for azure vms

# vm_control.sh <action> <group-name> <vm-name>
# action = start | stop | delete
