NEW QUESTION # 16
You are tasked with setting up fine-grained access control for a Kubernetes cluster running a microservices application. You need to ensure that developers can only access the resources related to their specific microservices while preventing them from accessing or modifying other services' resources. Define RBAC roles and permissions to achieve this, including details of the resources, verbs, and namespaces involved. Consider the following:
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:

Specify the YAML configurations for roles, role bindings, and service accounts to enable the required access control, ensuring developers only have access to their respective microservice's resources within their assigned namespaces. Solution (Step by Step) : 1. Define Roles:

2. Create Service Accounts: apiVersion: vl kind: ServiceAccount metadata: name: order-service-sa namespace: order-service-ns -- apiVersion: vl kind: ServiceAccount metadata: name: payment-service-sa namespace: payment-service-ns -- apiVersion: vl kind: ServiceAccount metadata: name: inventory-service-sa namespace: inventory-service-ns 3. Bind Roles to Service Accounts: -- apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: order-service-dev-binding namespace: order-service-ns roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: order-service-dev subjects: - kind: ServiceAccount name: order-service-sa namespace: order-service-ns -- apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: payment-service-dev-binding namespace: payment-service-ns roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: payment-service-dev subjects: - kind: ServiceAccount name: payment-service-sa namespace: payment-service-ns -- apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: inventory-service-dev-binding namespace: inventory-service-ns roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: inventory-service-dev subjects: - kind: ServiceAccount name: inventory-service-sa namespace: inventory-service-ns 4. Assign Service Accounts to Users: This step requires external authentication mechanisms like OIDC or LDAP. Assuming you have these mechanisms set up, you can associate the service accounts with specific users ('john.doe@example.com' , 'jane.doe@example.com', and 'peter.pan@example.com') using the configured authentication provider. Roles: Define the specific permissions for each microservice developer within their respective namespaces. The roles allow developers to access resources like Pods, Deployments, Services, ConfigMaps, and Secrets related to their assigned microservice. Service Accounts: Service accounts are created in each namespace for each microservice, representing the identity of the developer group. Role Bindings: Role bindings connect the defined roles with the service accounts, granting the associated permissions. User Association: This step connects the service accounts with individual developers through external authentication mechanisms, enabling them to utilize the assigned permissions. By following these steps, you ensure that developers can only access and manage resources associated with their respective microservices within their assigned namespaces. This fine-grained access control policy effectively restricts access and prevents developers from interfering with other microservices or resources. ,
