Explanation

To use a Kubernetes cluster in your deployment architecture on Oracle Cloud Infrastructure (OCI) with OCI DevOps service, the two recommended tools or services are: Terraform: Terraform is a widely used Infrastructure-as-Code (IaC) tool that allows you to define and manage your infra-structure resources in a declarative way. You can use Terraform to define and provision your Ku-bernetes cluster on OCI, including the necessary networking, compute resources, and container services. Ansible Collection: Ansible is an open-source automation tool that helps with configuration management, application deployment, and orchestration. The Ansible Collection for OCI provides modules and playbooks specifically designed to manage and interact with OCI resources, including Kubernetes clusters. You can use Ansible Collection to automate the deployment and management of your Kubernetes cluster on OCI. The other options mentioned are not directly related to managing Kubernetes clusters on OCI: Compute Jenkins Plug-in: Jenkins is a popular open-source automation server used for Continuous Integration/Continuous Deployment (CI/CD) processes. The Compute Jenkins Plug-in is specific to managing OCI compute resources using Jenkins but does not directly address Kubernetes cluster deployment. Chef Knife Plug-in: Chef is a configuration management tool that helps with managing infrastructure as code. The Chef Knife Plug-in is used to interact with the Chef tool, but it does not directly address Kubernetes cluster deployment on OCI. OCI Resource Manager: OCI Resource Manager is a service that helps you automate the process of deploying infrastructure resources on OCI. While it can be used to manage various OCI resources, including compute instances, it does not specifically focus on Kubernetes cluster deployment.

Explanation

The Kubernetes Cluster Autoscaler increases or decreases the size of a node pool automatically based on resource requests, rather than on resource utilization of nodes in the node pool. Reference:

The best practices that ABC Inc. should implement to incorporate DevSecOps into their DevOps process are:

• Follow established security guidelines, such as the OWASP DevSecOps guideline, during the development and testing process. The OWASP DevSecOps guideline is a set of recommendations and tools that help developers and testers integrate security into every stage of the software development lifecycle (SDLC). The guideline covers topics such as threat modeling, secure coding, code analysis, security testing, vulnerability management, etc.
• Perform regular scans for vulnerabilities and prioritize fixing them based on their severity. Vulnerability scanning is a process of identifying and assessing the security risks in your code, dependencies, images, containers, or infrastructure. You can use tools such as SonarQube, Sonatype Nexus IQ Server, or Twistlock to perform vulnerability scanning and generate reports with detailed information and remediation suggestions. You should also prioritize fixing the vulnerabilities based on their severity level and potential impact.
• Implement role-based access control and define roles and responsibilities for everyone involved in the development process. Role-based access control (RBAC) is a method of restricting access to resources based on the roles of the users or groups. You can use RBAC to enforce the principle of least privilege, which means granting only the minimum level of access required for each user or group to perform their tasks. You should also define clear roles and responsibilities for everyone involved in the development process, such as developers, testers, operations staff, security staff, etc., and assign them appropriate permissions and policies.

To securely store and version your application and automatically build, test, and deploy your application to OCI, you can choose the following OCI services:

• DevOps: This service enables you to automate the software development lifecycle (SDLC) and deliver software faster and more reliably. You can use DevOps to create projects, repositories, build pipelines, deployment pipelines, triggers, and artifacts.
• Oracle Cloud Infrastructure Registry: This service is a private Docker registry that allows you to store and manage your Docker images in OCI. You can use Registry to push and pull images from your local machine or from your build pipelines.
• Container Engine for Kubernetes: This service is a fully-managed platform that allows you to run your containerized applications in OCI. You can use Container Engine for Kubernetes to create and manage Kubernetes clusters, pods, services, and deployments.
