The WORKDIR instruction sets the working directory for all subsequent RUN, CMD, ENTRYPOINT, COPY, and ADD instructions in the Dockerfile. This means that after specifying WORKDIR, all these instructions will use the specified directory as their current working directory.

By implementing each module as anindependent service/process(which is a core feature ofmicroservices architecture), you can replace, update, or delete services without affecting the rest of the application. This ensuresdeployment independenceand makes it easier to adapt toarchitecture changesor technology upgrades without major disruptions.

Microservices architectureallows each service to be built with the best-suited technology stack for its specific function. Thisflexibilityensures that you are not tied to a single technology for the entire application, making future technology upgrades easier and eliminatinglong-term technology commitments.

Oracle Cloud Infrastructure (OCI) Events Serviceallows you to createrulesto automatically respond to changes in your OCI environment. To create a rule, you need the following items:

Rule Conditions:Conditions define theeventsthat will trigger the rule. This specifies what event (e.g., instance creation, object storage bucket modification) will trigger an action.

Actions:Actions define what should happen when aconditionis met. For example, the action might be to trigger anOCI Functionorsend a notification.

Resources provisioned through OCI Resource Manager (RM) can still be modified or destroyed from outside of RM, such as using the OCI Console, CLI, or other APIs. RM manages the lifecycle of resources created by its Terraform configurations, but it does not prevent other tools or methods from modifying or deleting those resources.

TheMonitoring servicein OCI can be used to trackmetricsfor various OCI resources, includingload balancers. You can monitor specific metrics, such asHTTP 5XX error rates, to identify issues.

By usingAlarms, you can set up thresholds for theHTTP 5XX error rateand receive notifications when the threshold is breached. The notifications can be configured throughOCI Notifications, which allows integration with email, PagerDuty, Slack, and other channels.

OCI Container Instances provide a serverless way to run containers in Oracle Cloud Infrastructure (OCI). They allow you to run containers without having to manage any underlying servers or clusters. This is ideal for development teams that need a simple, quick, and secure way to develop and test isolated web applications or RESTful APIs.

Oracle Cloud Infrastructure (OCI) Resource Manager uses Terraform to manage infrastructure resources. If you need to add new resources (e.g., a new CIDR block, subnet, and compute instance), you can simply make the necessary changes to the Terraform code defining the stack.

After modifying the Terraform configuration to include the new resources, you can run an Apply job in Resource Manager. The Apply job will provision the new resources in your OCI environment according to the updated Terraform code.

To create a Docker registry secret to pull images from the Oracle Cloud Infrastructure Registry (OCIR), you need to specify the correct parameters such as the region key, namespace, OCI username, and OCI authentication token.

Chosen command is correct because:

The kubectl create secret docker-registry command creates a Docker registry secret.

The --docker-server=.ocir.io specifies the correct endpoint for OCIR.

The --docker-username=/ provides both the tenancy namespace and the OCI username, which is the required format for authentication with OCIR.

The --docker-password='' specifies the OCI auth token, which acts as a password for authentication.

The --docker-email= is also included.

The other commands have errors, such as missing tenancy namespace or using incorrect flags (passwd instead of secret).

Helm chartsare used to manageKubernetesdeployments, notOCI Functions. Helm charts are deployed toKubernetes clusters, such asOCI Container Engine for Kubernetes (OKE), to manage containerized applications. OCI Functions are serverless and do not use Helm charts for deployment.

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.
