In the context ofOCI DevOps project service, the keyDevOps resourcesinclude:

Environments: These are used to represent deployment targets, such as Kubernetes clusters, compute instances, or functions.

Build pipelines: These automate the building, testing, and packaging of software.

Code repositories: These store source code for the application being built, providing version control and collaboration.

API integrationsarenotdirectly considered a DevOps resource in OCI DevOps projects. Instead, they facilitate communication and integration with other tools or services but do not represent a core component of DevOps projects likeenvironments, build pipelines, or code repositories.

Build pipelines in OCI DevOps are responsible for defining the stages involved in compiling, testing, and running software applications. These pipelines automate the process of building the code, running unit tests, scanning for vulnerabilities, and packaging the software, all of which occur before deploying the application.

Enhanced clusters in Oracle Container Engine for Kubernetes (OKE) provide advanced features such as granular control over cluster add-ons, workload identity, and improved worker node management. They also offer strong security measures and come with a financially-backed service level agreement (SLA) for Kubernetes API server uptime, ensuring higher reliability and support for production workloads.

You need therequired permissions(such as policies allowing secret management) to create and managesecretsinOracle Cloud Infrastructure (OCI) Vaultservice. These permissions are essential for performing operations such as creating, reading, and managing secrets.

Vault managed keyis required toencrypt the secretbefore it is stored in the OCI Vault. The managed key acts as the encryption key for securing the secret, ensuring its confidentiality.

To run applications on GPU worker nodes in Oracle Kubernetes Engine (OKE), you need to:

Select a managed node pool and choose a GPU shape for the worker nodes.

Use a GPU image that has the necessary CUDA libraries pre-installed to ensure that GPU workloads can be executed properly.

In the pod specification, specify the number of GPU resources required for the container to utilize the GPU hardware during execution. This allows Kubernetes to schedule the podon a node with an available GPU.

Thecorrect approachto upgrade an Oracle Container Engine for Kubernetes (OKE) cluster involves first upgrading theKubernetes control plane, followed by upgrading thenode pools. The control plane must be upgraded first to ensure compatibility with newer versions of Kubernetes, as node pools rely on the control plane for orchestration and management.

After upgrading the control plane, eachnode poolis upgraded to match the new Kubernetes version. This phased approach ensures the cluster remains in a stable state during the upgrade.

The Oracle Cloud Infrastructure Logging service has several log categories that users can utilize:

Custom Logs: Users can create their own logs to collect application-specific data.

Audit Logs: These logs contain audit records that provide information about activities performed on resources, generated by OCI Audit service.

Service Logs: These are logs generated by OCI services, providing information about the functioning and performance of the services.

Execution Logs is not a valid log category in OCI Logging. There are no "execution logs" as a defined category for the Logging service.

OCI DevOps service can be used to deploy Helm charts for Kubernetes-based applications running on Oracle Kubernetes Engine (OKE). For deploying the Helm chart through the OCI DevOps service, the Helm chart must be stored in the OCI Container Registry. This allows the OCI DevOps service to easily access the Helm chart during the deployment process.

Oracle Cloud Infrastructure Functions is a serverless compute service that supports a consumption-based pricing model. This means that you are only charged for the compute resources when your function is invoked. This is ideal for intermittent, dynamic, and irregular workloads since the company does not need to provision infrastructure in advance, and costs are directly tied to usage.

In Kubernetes clusters created by Oracle Container Engine for Kubernetes (OKE), data in etcd (the key-value store that holds cluster state and configuration data) is encrypted at rest by default using encryption keys managed by Oracle. Oracle manages the encryption using a master encryption key to protect sensitive data.
