The sample deploys and exposes the Apache web server as a service. 2. By default, the ingress controller creates a Kubernetes service that assigns random NodePort ports. Create the Kubernets Cluster (ACS) First an Azure Container Service is created with Kubernetes as orchestrator and then the credentials are retrieved and inserted into the kubectl configuration: az acs create --orchestrator-type=kubernetes --agent-vm-size=Standard_D1_v2 --agent-count=1 --resource-group ACS-SSL-Ingress --name=acs-2019-02-05 . Generate YAML for a Kubernetes Pod $ kubectl run my-nginx --image nginx --restart Never --dry-run -o yaml output Generate YAML for a Kubernetes Deployment $ kubectl create deployment my-deploy --image nginx --dry-run -o yaml output It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. Perform the following steps to deploy the Citrix ingress controller. command: kubectl get ingress -n <NAMESPACE> . sorry.

These two options can be added to many commands in kubectl, including kubectl run and kubectl create. For more information, see the Kubernetes documentation. This will create an Azure Load Balancer that routes traffic to the ingress controller service. The Deployment's Pod runs the hello-app container image. Deploy Citrix Ingress Controller. for the kubectl command-line interface. To start creating a secret with kubectl, first create the files to store the sensitive information: echo -n ' [username]' > [file1] echo -n ' [password]' > [file2] The -n option tells echo not to append a new line at the end of the string. Once you update the environment variables, save the YAML file and deploy it using the following command: kubectl create -f citrix-k8s-ingress-controller.yaml Verify if the Citrix ingress controller is deployed successfully using the following command: kubectl get pods --all-namespaces What's next Managing Kubernetes Objects Using Object Configuration (Imperative) kubectl minio tenant create minio-tenant-1 \ --servers 4 \ --volumes 16 \ --capacity 16Ti \ --storage-class direct-csi-min-io \ --namespace minio-tenant-1. It creates two files inside the container. 4.1 Create a Service for the Ingress Controller Pods .
