* [Static provisioning](https://cloud.ibm.com/docs/containers?topic=containers-kube_conceptsstatic_provisioning)







 Dynamic provisioning 

Use dynamic provisioning if you want to give developers the freedom to provision storage when they need it.

Dynamic provisioning is a feature that is native to Kubernetes and that allows a cluster developer to order storage with a pre-defined type and configuration without knowing all the details about how to provision the physical storage device. To abstract the details for the specific storage type, the cluster admin must create [storage classes](https://cloud.ibm.com/docs/containers?topic=containers-kube_conceptsstorageclasses) that the developer can use, or use the storage classes that are provided with the IBM Cloud® storage plug-ins.

To order the storage, you must create a PVC. The PVC determines the specification for the storage that you want to provision. After the PVC is created, the storage device and the PV are automatically created for you.

The following image shows how file storage is dynamically provisioned in a cluster. This sample flow works similarly with other storage types, such as block storage.

![Sample flow to dynamically provision file storage in a cluster, as described in the following list.](https://cloud.ibm.com/docs-content/v1/content/4d497aff9e27b92fbbc2ee4e343a9ec4549cb1d7/containers/images/cs_storage_dynamic-01-01.svg)

Figure 1. Sample flow to dynamically provision file storage in a cluster



1. The user creates a persistent volume claim (PVC) that specifies the storage type, storage class, size in gigabytes, number of IOPS, and billing type. The storage class determines the type of storage that is provisioned and the allowed ranges for size and IOPS. Creating a PVC in a cluster automatically triggers the storage plug-in for the requested type of storage to provision storage with the given specification.
2. The storage device is automatically ordered and provisioned into your IBM Cloud infrastructure account.

FAQs 

Answers to common questions about the IBM Cloud® Code Engine service.



 What is IBM Cloud Code Engine? 

Code Engine is developed by IBM and it is built with many open source components. The goal is to extend the capabilities of Kubernetes to help you create modern, source-centric containerized, and serverless apps that run on your Kubernetes cluster. The platform is designed to address the needs of developers who today must decide what type of app they want to run in the cloud: 12-factor apps, containers, or functions. For more information, see [About Code Engine](https://cloud.ibm.com/docs/codeengine?topic=codeengine-about).

With Code Engine, you can deploy applications, run jobs, and even build source code from a single dashboard.





 What is a project? 

A project is a grouping of Code Engine entities such as applications, jobs, and builds. A project is based on a Kubernetes namespace. The name of your project must be unique within your IBM Cloud® resource group, user account, and region. Projects are used to manage resources and provide access to its entities.

A project provides the following items.



* Provides a unique namespace for entity names.
* Manages access to project resources (inbound access).
* Manages access to backing services, registries, and repositories (outbound access).
* Has an automatically generated certificate for Transport Layer Service (TLS).



For more information about projects, see [Manage projects](https://cloud.ibm.com/docs/codeengine?topic=codeengine-manage-project).





 Where can I find code samples? 

You can find code samples to help you explore the capabilities of Code Engine. Visit our [Code Engine code samples repository on GitHub](https://github.com/IBM/CodeEngine).

4. If you have pods that mount the secret, either remove the pod or the deployment that manages the pod, or update the pod and deployment YAML to use a different secret instead.



* To remove a pod or deployment:

kubectl delete pod <pod_name> -n <namespace>

kubectl delete deployment <deployment_name> -n <namespace>
* To update an existing pod or deployment:



1. Get the pod or deployment YAML file.

kubectl get pod <pod_name> -o yaml

kubectl get deployment <deployment_name> -o yaml
2. Copy the YAML file and in the spec.volumes section, change the name of the secret that you want to use.
3. Apply the change in your cluster.

kubectl apply -f pod.yaml

kubectl apply -f deployment.yaml
4. Verify that a new pod is created with the updated volume specification.
After that, you bind the database to the Kubernetes cluster through the private endpoint with the cluster service bind command.

ibmcloud ks cluster service bind <your_cluster_name> <resource_group> <your_database_deployment> --key <your-private-key>

Verify - Verify that the Kubernetes secret was created in your cluster namespace. Running the following command, you get the API key for accessing the instance of your deployment that's provisioned in your account.

kubectl get secrets --namespace=default

More information on binding services is found in the [Kubernetes Service documentation](https://cloud.ibm.com/docs/containers?topic=containers-service-bindingbind-services).





 Configuring in your Kubernetes app 

When you bind your application to Kubernetes Service, it creates an environment variable from the cluster's secrets. Your deployment's connection information lives in BINDING as a JSON object. Load and parse the JSON object into your application to retrieve the information your application's driver needs to make a connection to the database.

The [Connection Strings](https://cloud.ibm.com/docs/databases-for-etcd?topic=databases-for-etcd-connection-stringsconnection-string-breakdown) page contains a reference of the JSON fields.

* etcd data store: Stores all Kubernetes resources of a cluster, such as Services, Deployments, and Pods. Kubernetes ConfigMaps and Secrets are app data that is stored as key value pairs so that they can be used by an app that runs in a pod. Data in etcd is stored on the local disk of the Kubernetes master and is backed up to IBM Cloud Object Storage. Data is encrypted during transit to IBM Cloud Object Storage and at rest. You can choose to enable encryption for your etcd data on the local disk of your Kubernetes master by [enabling IBM Key Protect encryption](https://cloud.ibm.com/docs/containers?topic=containers-encryptionkeyprotect) for your cluster. When etcd data is sent to a pod, data is encrypted via TLS to ensure data protection and integrity.
* kube-apiserver: Serves as the main entry point for all cluster management requests from the worker node to the Kubernetes master. The API server validates and processes requests that change the state of cluster resources, such as pods or services, and stores this state in the etcd data store.
* kube-scheduler: Decides where to deploy pods, considering the capacity and performance needs, hardware and software policy constraints, anti-affinity specifications, and workload requirements. If no worker node can be found that matches the requirements, the pod is not deployed in the cluster.
* kube-controller-manager: Responsible for monitoring replica sets, and creating corresponding pods to achieve the specified state.
* Konnectivity: IBM Cloud Kubernetes Service-specific component to provide secured network connectivity for all Kubernetes master to worker node communication. The Konnectivity server works with the Konnectivity agent to securely connect the master to the worker node. This connection supports apiserver proxy requests to your pods and services, and kubectl top, exec, attach, and logs requests to the kubelet. The connection from the worker nodes to the master is automatically secured with TLS certificates.
