Terraform will use these values to authenticate to Azure before provisioning your resources. Your terraform. After you have saved your customized variables file, initialize your Terraform workspace, which will download the provider and initialize it with the values provided in your terraform.
In your initialized directory, run terraform apply and review the planned actions. Your terminal output should indicate the plan is running and what resources will be created. You can see this terraform apply will provision an Azure resource group and an AKS cluster.
Confirm the apply with a yes. This process should take approximately 10 minutes. Upon successful application, your terminal prints the outputs defined in aks-cluster.
Now that you've provisioned your AKS cluster, you need to configure kubectl. Run the following command to retrieve the access credentials for your cluster and automatically configure kubectl. The resource group name and Kubernetes Cluster name correspond to the output variables showed after the successful Terraform run.
To verify that your cluster's configuration, visit the Azure Portal's Kuberentes resource view. Azure recommends using this view over the default Kubernetes dashboard, since the AKS dashboard add-on is deprecated for Kubernetes versions 1.
Note that under the covers, rsync may or may not be used. In general, local files used as the source must exist before Packer is run. This is great for catching typos and ensuring that once a build is started, that it will succeed. However, this also means that you can't generate a file during your build and then upload it using the file provisioner later. A convenient workaround is to upload a directory instead of a file. The directory still must exist, but its contents don't.
You can write your generated file to the directory during the Packer run, and have it be uploaded later. The behavior when uploading symbolic links depends on the communicator. The Docker communicator will preserve symlinks, but all other communicators will treat local symlinks as regular files. If you wish to preserve symlinks when uploading, it's recommended that you use tar. Below is an example of what that might look like:.
Because of the way our WinRM transfers works, it can take a very long time to upload and download even moderately sized files. If you're experiencing slowness using the file provisioner on Windows, it's suggested that you set up an SSH server and use the ssh communicator. Verify that the metrics server has been deployed. If successful, you should see something like this. The following command will schedule the resources necessary for the dashboard. Now, create a proxy server that will allow you to navigate to the dashboard from the browser on your local machine.
To use the Kubernetes dashboard, you need to create a ClusterRoleBinding and provide an authorization token. This gives the cluster-admin permission to access the kubernetes-dashboard. Authenticating using kubeconfig is not an option. You can read more about it in the Kubernetes documentation. In another terminal do not close the kubectl proxy process , create the ClusterRoleBinding resource.
Select "Token" on the Dashboard UI then copy and paste the entire token you receive into the dashboard authentication screen to sign in. You are now signed in to the dashboard for your Kubernetes cluster. Navigate to the "Cluster" page by clicking on "Cluster" in the left navigation bar. You should see a list of nodes in your cluster. Congratulations, you have provisioned an EKS cluster, configured kubectl , and deployed the Kubernetes dashboard.
If you'd like to learn how to manage your EKS cluster using the Terraform Kubernetes Provider, leave your cluster running and continue to the Kubernetes provider Learn tutorial. By keeping the Terraform configuration for provisioning a Kubernetes cluster and managing a Kubernetes cluster resources separate, changes in one repository don't affect the other. In addition, the modularity makes the configuration more readable and enables you to scope different permissions to each workspace.
If not, remember to destroy any resources you create once you are done with this tutorial. Symmetric keys : When you create a new device identity in IoT Hub, the service creates two keys. You place one of the keys on the device, and it presents the key to IoT Hub when authenticating. When you create a new device identity in IoT Hub, you provide thumbprints from both certificates.
When the device authenticates to IoT Hub, it presents one certificate and IoT Hub verifies that the certificate matches its thumbprint. This article covers using symmetric keys as your authentication method. If you want to use X. If you have many devices to set up and don't want to manually provision each one, use one of the following articles to learn how IoT Edge works with the IoT Hub device provisioning service:.
These tasks have different prerequisites and utilities used to accomplish them. Make sure you have all the prerequisites covered before proceeding. Each utility has its own prerequisites:. A free or standard IoT hub in your Azure subscription.
Azure CLI in your environment. At a minimum, your Azure CLI version must be 2. Use az --version to validate. This version supports az extension commands and introduces the Knack command framework.
Be sure to review the supported systems list for a list of supported SKUs. Sign in to the Azure portal and navigate to your IoT hub. For these operations to work, you need to sign in to your Azure account and select your hub.
Click on the If you don't see the ellipsis, click on or hover over the header. In the output screen, you see the result of the command. The device info is printed, which includes the deviceId that you provided and the connectionString that you can use to connect your physical device to your IoT hub. Use the az iot hub device-identity create command to create a new device identity in your IoT hub.
