ApplicationLoadBalancer

Manages ApplicationLoadBalancer Resource on IONOS Cloud.

Overview

• Resource Name: ApplicationLoadBalancer

• Resource Group: alb.ionoscloud.crossplane.io

• Resource Version: v1alpha1

• Resource Scope: Cluster

Usage

In order to manage resources on IONOS Cloud using Crossplane Provider, you need to have Crossplane Provider for IONOS Cloud installed into a Kubernetes Cluster, as a prerequisite. For a step-by-step guide, check the following link.

It is recommended to clone the repository for easier access to the example files.

Create

Use the following command to create a resource instance. Before applying the file, check the properties defined in the spec.forProvider fields:

kubectl apply -f examples/ionoscloud/alb/applicationloadbalancer.yaml

Note: The command should be run from the root of the crossplane-provider-ionoscloud directory.

Update

Use the following command to update an instance. Before applying the file, update the properties defined in the spec.forProvider fields:

kubectl apply -f examples/ionoscloud/alb/applicationloadbalancer.yaml

Note: The command should be run from the root of the crossplane-provider-ionoscloud directory.

Wait

Use the following commands to wait for resources to be ready and synced. Update the <instance-name> accordingly:

kubectl wait --for=condition=ready applicationloadbalancers.alb.ionoscloud.crossplane.io/<instance-name>

kubectl wait --for=condition=synced applicationloadbalancers.alb.ionoscloud.crossplane.io/<instance-name>

Get

Use the following command to get a list of the existing instances:

kubectl get -f applicationloadbalancers.alb.ionoscloud.crossplane.io

Note: Use options --output wide, --output json to get more information about the resource instances.

Delete

Use the following command to destroy the resources created by applying the file:

kubectl delete -f examples/ionoscloud/alb/applicationloadbalancer.yaml

Note: The command should be run from the root of the crossplane-provider-ionoscloud directory.
