Modules in Terraform are reusable components that allow you to encapsulate and organize your infrastructure code.

• Modules help in breaking down complex infrastructure into smaller, manageable components

• They promote reusability and maintainability of code

• Modules can be shared and used across different projects

• Example: Creating a module for provisioning a virtual machine in Azure

Use encrypted variables, limit access to credentials, and utilize secure storage solutions.

• Encrypt sensitive variables using tools like Vault or AWS KMS

• Limit access to credentials by using least privilege principles

• Store credentials securely in a password manager or key vault

• Avoid hardcoding credentials in Terraform configuration files

VPC is a virtual private cloud that allows you to create isolated networks, NAT Gateway enables instances in a private subnet to connect to the internet, NACL controls inbound and outbound traffic at the subnet level, SG controls traffic at the instance level.

• VPC is a virtual network in the cloud that you can define and customize, providing a secure environment for your resources.

• NAT Gateway allows instances in a priva...read more

A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.

• Start with a base image

• Use the FROM keyword to specify the base image

• Add any necessary dependencies using the RUN keyword

• Copy application code into the image using the COPY keyword

• Expose any necessary ports using the EXPOSE keyword

• Specify the command to run when the container starts using the CMD ke

CICD stages include build, test, deploy, and monitor. Common issues include integration challenges and pipeline failures.

• Stages: Build, Test, Deploy, Monitor

• Issues: Integration challenges, Pipeline failures

• Example: Integration challenges with third-party tools delaying deployment

To check if a pod in ReplicaSet went down or failed, monitor the pod status, logs, and events.

Memory in Go is managed using garbage collection, which automatically frees up memory that is no longer in use.

• Go uses a garbage collector to automatically manage memory allocation and deallocation.

• Memory is allocated on the heap, and garbage collection is used to free up memory that is no longer needed.

• Pointers are used to reference memory locations, allowing for efficient memory management.

• Examples: var x *int = new(

Project internal architecture refers to the structure and organization of the codebase and components within a software project.

• Components and modules are organized in a logical manner to ensure scalability and maintainability.

• Design patterns such as MVC, MVVM, or microservices may be used to structure the codebase.

• Communication between components is defined through interfaces and APIs.

• Data flow and dependencies are ma...read more
