NEW QUESTION 19
A service you are deploying to Oracle infrastructure (OCI) Container En9ine for Kubernetes (OKE) uses a docker image from a private repository Which configuration is necessary to provide access to this repository from OKE?

Add a generic secret on the cluster containing your identity credentials. Then specify a registrycredentials property in the deployment manifest.

Create a docker-registry secret for OCIR with API key credentials on the cluster, and specify the imagepullsecret property in the application deployment manifest.

Create a docker-registry secret for OCIR with identity Auth Token on the cluster, and specify the image pull secret property in the application deployment manifest.

Create a dynamic group for nodes in the cluster, and a policy that allows the dynamic group to read repositories in the same compartment.

Pulling Images from Registry during Deployment
During the deployment of an application to a Kubernetes cluster, you’ll typically want one or more images to be pulled from a Docker registry. In the application’s manifest file you specify the images to pull, the registry to pull them from, and the credentials to use when pulling the images. The manifest file is commonly also referred to as a pod spec, or as a deployment.yaml file (although other filenames are allowed).
If you want the application to pull images that reside in Oracle Cloud Infrastructure Registry, you have to perform two steps:
– You have to use kubectl to create a Docker registry secret. The secret contains the Oracle Cloud Infrastructure credentials to use when pulling the image. When creating secrets, Oracle strongly recommends you use the latest version of kubectl To create a Docker registry secret:
1- If you haven’t already done so, follow the steps to set up the cluster’s kubeconfig configuration file and (if necessary) set the KUBECONFIG environment variable to point to the file. Note that you must set up your own kubeconfig file. You cannot access a cluster using a kubeconfig file that a different user set up.
2- In a terminal window, enter:
$ kubectl create secret docker-registry <secret-name> –docker-server=<region-key>.ocir.io –docker-username='<tenancy-namespace>/<oci-username>’ –docker-password='<oci-auth-token>’ –docker-email='<email-address>’ where:
<secret-name> is a name of your choice, that you will use in the manifest file to refer to the secret . For example, ocirsecret
<region-key> is the key for the Oracle Cloud Infrastructure Registry region you’re using. For example, iad. See Availability by Region.
ocir.io is the Oracle Cloud Infrastructure Registry name.
<tenancy-namespace> is the auto-generated Object Storage namespace string of the tenancy containing the repository from which the application is to pull the image (as shown on the Tenancy Information page). For example, the namespace of the acme-dev tenancy might be ansh81vru1zp. Note that for some older tenancies, the namespace string might be the same as the tenancy name in all lower-case letters (for example, acme-dev).
<oci-username> is the username to use when pulling the image. The username must have access to the tenancy specified by <tenancy-name>. For example, [email protected] . If your tenancy is federated with Oracle Identity Cloud Service, use the format oracleidentitycloudservice/<username>
<oci-auth-token> is the auth token of the user specified by <oci-username>. For example, k]j64r{1sJSSF-;)K8
<email-address> is an email address. An email address is required, but it doesn’t matter what you specify. For example, [email protected]
– You have to specify the image to pull from Oracle Cloud Infrastructure Registry, including the repository location and the Docker registry secret to use, in the application’s manifest file.

NEW QUESTION 30
Your Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) administrator has created an OKE cluster with one node pool in a public subnet. You have been asked to provide a log file from one of the nodes for troubleshooting purpose.
Which step should you take to obtain the log file?

ssh into the node using public key.

ssh into the nodes using private key.

It is impossible since OKE is a managed Kubernetes service.

Use the username open and password to login.

Kubernetes cluster is a group of nodes. The nodes are the machines running applications. Each node can be a physical machine or a virtual machine. The node’s capacity (its number of CPUs and amount of memory) is defined when the node is created. A cluster comprises:
– one or more master nodes (for high availability, typically there will be a number of master nodes)
– one or more worker nodes (sometimes known as minions)
Connecting to Worker Nodes Using SSH
If you provided a public SSH key when creating the node pool in a cluster, the public key is installed on all worker nodes in the cluster. On UNIX and UNIX-like platforms (including Solaris and Linux), you can then connect through SSH to the worker nodes using the ssh utility (an SSH client) to perform administrative tasks.
Note the following instructions assume the UNIX machine you use to connect to the worker node:
Has the ssh utility installed.
Has access to the SSH private key file paired with the SSH public key that was specified when the cluster was created.
How to connect to worker nodes using SSH depends on whether you specified public or private subnets for the worker nodes when defining the node pools in the cluster.
Connecting to Worker Nodes in Public Subnets Using SSH
Before you can connect to a worker node in a public subnet using SSH, you must define an ingress rule in the subnet’s security list to allow SSH access. The ingress rule must allow access to port 22 on worker nodes from source 0.0.0.0/0 and any source port To connect to a worker node in a public subnet through SSH from a UNIX machine using the ssh utility:
1- Find out the IP address of the worker node to which you want to connect. You can do this in a number of ways:
Using kubectl. If you haven’t already done so, follow the steps to set up the cluster’s kubeconfig configuration file and (if necessary) set the KUBECONFIG environment variable to point to the file. Note that you must set up your own kubeconfig file. You cannot access a cluster using a kubeconfig file that a different user set up. See Setting Up Cluster Access. Then in a terminal window, enter kubectl get nodes to see the public IP addresses of worker nodes in node pools in the cluster.
Using the Console. In the Console, display the Cluster List page and then select the cluster to which the worker node belongs. On the Node Pools tab, click the name of the node pool to which the worker node belongs. On the Nodes tab, you see the public IP address of every worker node in the node pool.
Using the REST API. Use the ListNodePools operation to see the public IP addresses of worker nodes in a node pool.
2- In the terminal window, enter ssh opc@<node_ip_address> to connect to the worker node, where <node_ip_address> is the IP address of the worker node that you made a note of earlier. For example, you might enter ssh [email protected].
Note that if the SSH private key is not stored in the file or in the path that the ssh utility expects (for example, the ssh utility might expect the private key to be stored in ~/.ssh/id_rsa), you must explicitly specify the private key filename and location in one of two ways:
Use the -i option to specify the filename and location of the private key. For example, ssh -i ~/.ssh/my_keys/my_host_key_filename [email protected] Add the private key filename and location to an SSH configuration file, either the client configuration file (~/.ssh/config) if it exists, or the system-wide client configuration file (/etc/ssh/ssh_config). For example, you might add the following:
Host 192.0.2.254 IdentityFile ~/.ssh/my_keys/my_host_key_filename
For more about the ssh utility’s configuration file, enter man ssh_config Note also that permissions on the private key file must allow you read/write/execute access, but prevent other users from accessing the file. For example, to set appropriate permissions, you might enter chmod 600 ~/.ssh/my_keys/my_host_key_filename. If permissions are not set correctly and the private key file is accessible to other users, the ssh utility will simply ignore the private key file.
