DevOps & Cloud Security Guides
A consolidated DevOps cheat sheet covering CI/CD foundations, Git, Docker, Kubernetes, Terraform and multi-cloud CLIs circulated on social media this week (x.com). freeCodeCamp published a cloud security essentials guide covering root vs. IAM users, the Shared Responsibility model, and permissions for infrastructure protection (x.com).
Two learning guides moved through developer feeds this week: a DevOps cheat sheet bundled Git, Docker, Kubernetes, Terraform and cloud command-line tools, while freeCodeCamp published an Amazon Web Services security primer on account access and permissions. (x.com) (freecodecamp.org) The DevOps guide grouped the stack around a software delivery pipeline: Git for version history, Continuous Integration and Continuous Delivery for automated testing and release steps, Docker for packaging apps, Kubernetes for running containers, Terraform for infrastructure as code, and cloud command-line interfaces for Amazon Web Services, Microsoft Azure and Google Cloud. (x.com) (docs.github.com) (docs.docker.com) (developer.hashicorp.com) freeCodeCamp’s article focused on Amazon Web Services basics that are easy to misuse in a first cloud account: the root user has full control of the account, Identity and Access Management users get narrower permissions, and multi-factor authentication adds a second sign-in check. (freecodecamp.org) (docs.aws.amazon.com) DevOps is the practice of moving code from a developer’s laptop into production through repeatable steps instead of manual handoffs. GitHub says GitHub Actions runs those workflows inside a repository, and Docker says its official Actions can build container images inside the same pipeline. (docs.github.com) (docs.docker.com) Cloud security starts with a simpler split: the provider protects the underlying data centers and core infrastructure, while the customer protects identities, data, operating systems and service settings inside the account. Amazon Web Services describes that division as the Shared Responsibility Model. (aws.amazon.com) (docs.aws.amazon.com) That is why the access lesson matters more than a product checklist. Amazon Web Services says the root user should not be used for everyday work, recommends least-privilege permissions, and says human users should use temporary credentials through an identity provider when possible. (docs.aws.amazon.com 1) (docs.aws.amazon.com 2) The tools in the DevOps stack connect in sequence. Developers commit code in Git, a Continuous Integration job tests it, Docker packages it into an image, Kubernetes runs that image across servers, and Terraform defines the infrastructure those services need in configuration files. (freecodecamp.org) (docs.github.com) (developer.hashicorp.com) freeCodeCamp’s security guide uses Amazon Web Services examples, but the ideas travel across cloud platforms: do not use the all-powerful account owner for routine work, turn on multi-factor authentication, and grant only the permissions a person or application actually needs. (freecodecamp.org) (docs.aws.amazon.com) Amazon Web Services tightened one of those defaults in June 2025, when it said Identity and Access Management now enforces multi-factor authentication for root users across all account types. That change pushed a long-standing best practice closer to a baseline control. (aws.amazon.com) (docs.aws.amazon.com) Taken together, the two guides map the same path from different ends: one shows how software gets shipped, and the other shows how the keys to that system should be handled.
