Exploring

  • Lets create a Ubuntu Server 20.04 with size Standard_B1s
  • Select the necessary options and create the virtuam machine Preview Preview Preview Preview
  • Lets download the template Preview Preview Preview
  • Overview of Templates
    • When we try to create any thing in Azure, Azure will create a template and deploy it.
    • The deployment of template leads to creation of resources Preview
  • Basic Idea behind templates:
    • When we want to do the same activity again, rather that reselecting the stuff from azure portal, we can deploy the template.
  • Assume your application deployment has lot of vms and other azure resources, creating them manually for every environment will be difficult to create, so as a solution
    • We can create the reusable template and deploy this reusable template with different parameters for different environments.

Azure Resource Manager Templates

  • So, to automate application deployments on Azure we should be able to create/modify the templates to suit to your application needs
  • Skills to acquire
    • Understanding JSON
    • Writing ARM Template from scratch
    • Modify the existing ARM Templates
  • ARM Templates can be deployed from
    • Portal
    • CLI/Powershell
    • API
  • This gives us the flexibility to integrate the ARM Template deployment with any CI/CD tool.
  • Azure has developed a Domain Specific language where we can use declarative syntax to deploy Azure resources which is called as Bicep

JSON

  • Refer Here for the JSON and YAML Tutorial

  • Json is all about writing the data in the form of name value pairs

  • Here when we try to do this value can be of the following formats

    • text
    • number
    • true/false
    • list
    • complex i.e it has more name value pairs
  • For doing this json has specific syntax

<name>: <value>
  • string/text
'name' : 'QualityThought'
  • number
'started': 2010
'age': 11
  • boolean
'classroom': false
'online': true
  • list
'courses': [ 'AWS', 'Azure', 'DevOps', 'Python', 'DataScience' ]
  • complex or object
address: {
    'flatno': '209-B',
    'building': 'Nilgiri Block',
    'landmark': 'Ameerpet Metro'
}
  • Academics json
{
	"schooling": {
		"name": "Bhartiya Vidya Bhavan",
		"academic percentage": 85.6
	},
	"intermediate": {
		"name" : "FITJEE",
		"academic percentage" : 94,
		"specialization": ["Maths", "Physics", "Chemistry"]
		
	},
	"graduation": {
		"name": "NIT",
		"academic percentage": 75,
		"specialization" : "Computer Science and Engieering",
		"degree": "B.Tech"
		
	}
}
  • Json is generally stored in files with .json extension.
  • JSON is widely used to represent data and is a common format in web applications.
