Ansible, an open-source automation tool, has gained popularity among cloud engineering professionals for its ability to simplify and streamline infrastructure management tasks. In this blog, we will explore five code examples of Ansible for cloud engineering, showcasing how Ansible can be used to automate common cloud-related tasks and enhance the efficiency of cloud operations.

Provisioning EC2 Instances on AWS

Ansible enables cloud engineers to automate the provisioning of Amazon EC2 instances on AWS. Using Ansible’s AWS modules, such as ec2_instance and ec2_key, you can define the desired configuration for the EC2 instance, including instance type, security groups, key pairs, and tags. Here’s an example playbook that provisions an EC2 instance:

- name: Provision EC2 Instance
  hosts: localhost
  gather_facts: false
    - name: Launch EC2 Instance
        instance_type: t2.micro
        image: ami-0c94855ba95c71c99
        key_name: my-keypair
        security_groups: my-security-group
          Name: my-instance
      register: ec2

    - name: Display EC2 Instance Details
        var: ec2
Deploying Applications on Kubernetes

Ansible can be used to automate the deployment of applications on Kubernetes clusters. With Ansible’s Kubernetes modules, such as k8s and k8s_scale, you can define the desired deployment, services, and replicas for your application. Here’s an example playbook that deploys a sample application on a Kubernetes cluster:

- name: Deploy Application on Kubernetes
  hosts: localhost
  gather_facts: false
    - name: Deploy Kubernetes Deployment
        state: present
        src: deployment.yaml

    - name: Expose Kubernetes Service
        state: present
        src: service.yaml

    - name: Scale Kubernetes Deployment
        name: my-app
        replicas: 3
Configuring Load Balancers on Azure

Ansible provides modules for configuring load balancers on cloud platforms like Azure. Using Ansible’s Azure modules, such as azure_rm_loadbalancer and azure_rm_publicipaddress, you can define load balancer rules, backend pools, and public IP addresses. Here’s an example playbook that configures a load balancer on Azure:

- name: Configure Azure Load Balancer
  hosts: localhost
  gather_facts: false
    - name: Create Public IP Address
        resource_group: my-resource-group
        name: my-public-ip
        allocation_method: Static

    - name: Create Load Balancer
        resource_group: my-resource-group
        name: my-load-balancer
          - name: my-frontend-ip
            public_ip_address: my-public-ip
          - name: my-backend-pool
Managing RDS Databases on AWS

Ansible allows cloud engineers to automate the management of Amazon RDS databases on AWS. Using Ansible’s AWS RDS modules, such as rds_instance and rds_param_group, you can create, modify, and delete RDS database instances. Here’s an example playbook that creates an RDS database instance:

    - name: Create RDS Instance
        instance_name: my-db-instance
        db_instance_identifier: my-db-instance
        engine: postgres
        instance_class: db.t2.micro
        master_username: admin
        master_password: MyP@ssw0rd
        vpc_security_group_ids: sg-12345678
          Name: my-db-instance
Configuring Firewall Rules on Google Cloud Platform (GCP)

Ansible provides modules for managing firewall rules on GCP. Using Ansible’s GCP modules, such as gcp_compute_firewall, you can define firewall rules to allow or deny incoming traffic to your instances. Here’s an example playbook that configures a firewall rule on GCP:

yamlCopy code- name: Configure GCP Firewall Rule
  hosts: localhost
  gather_facts: false
    - name: Create Firewall Rule
        name: my-firewall-rule
        network: default
          - protocol: tcp
              - "80"
              - "443"
        target_tags: web-server


Ansible offers a powerful automation framework for cloud engineering tasks, simplifying the management of cloud resources across various platforms. From provisioning instances and deploying applications to configuring load balancers and managing databases, Ansible provides a consistent and declarative approach to cloud infrastructure management. By utilizing these code examples and exploring Ansible’s vast array of modules, cloud engineering professionals can streamline their workflows, reduce manual effort, and achieve greater efficiency in managing cloud infrastructure.
