states an intended goal and then allows the underlying IaC tools to decide how those goals are implemented. SQL is a commonly known declarative programming language. Amazon Web Services (AWS) CloudFormation templates, among others, are written in the declarative style of infrastructure as code. ...
Infrastructure as code is a modern technology and process in which infrastructure is provisioned and managed using machine-readable code files. Frameworks such as Terraform and CloudFormation allow teams to write declarative or imperative code files, check those files into their version control system ...
Here’s an example of declarative IaC code: Resource: WebServer Type: AWS::EC2::Instance Properties: ImageId: "ami-0abcdef1234567890" InstanceType: t2.micro SecurityGroups: - WebServerSG KeyName: MyKeyPair In this example, the desired state is defined for an AWS EC2 instance. It specifies...
What is declarative configuration? Declarative configuration specifies the desired state of a system without outlining the steps to achieve it. The system's underlying management tools are responsible for executing the necessary actions to maintain the declared state. This approach contrasts with imperative...
Write in a Declarative Way: Scenarios should be written how the user would describe them. Avoid scenarios that only describe clicking links and entering data in form fields. Good Grammar: Write like your high school English teacher will be grading your Gherkin. Poor grammar, misspellings, and in...
