Install Kommander in a Non-air-gapped Environment
To install the Kommander component of DKP in a Non-air-gapped Environment, you will need to ensure you have the prerequisites below met.
Prerequisites
Before installing Kommander:
Ensure you have the version of the CLI that matches the DKP version you want to install.
You have configured a Konvoy cluster using the Advanced Konvoy Configuration for infrastructure provider specific instructions on building a cluster-based on environment.
Review the Management Cluster Application Requirements and Workspace Platform Application Defaults and Resource Requirements to ensure that your cluster has sufficient resources.
Ensure you have a default
StorageClassconfigured as shown below.If you want to customize your cluster’s domain or certificate, ensure you review the respective documentation sections:
Configure a Default StorageClass
The cluster where Kommander is installed must have a default StorageClass configured. Use the following command to verify one is configured:
kubectl get scThe output should look similar to this. Note the (default) after the name:
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
ebs-sc (default) ebs.csi.aws.com Delete WaitForFirstConsumer false 41sIf the desired StorageClass is not set as default, add the following annotation to the StorageClass manifest:
annotations:
storageclass.kubernetes.io/is-default-class: "true"More information on setting a StorageClass as default can be found at Changing the default storage class in the Kubernetes documentation.
Install Kommander
To customize your Kommander installation, see the Kommander Install Configuration for more details.
Before running the commands below, ensure that your kubectl configuration references the cluster on which you want to install Kommander, otherwise it will install on the bootstrap cluster. You can do this by setting the KUBECONFIG environment variable to the appropriate kubeconfig file’s location.
NOTE: An alternative to initializing the KUBECONFIG environment variable as stated earlier is to use the --kubeconfig=cluster_name.conf flag. This ensures that Kommander is installed on the correct cluster.
Install Kommander:
dkp install kommanderTIP: Sometimes, applications require a longer period of time to deploy, which causes the installation to time out. Add the --wait-timeout <time to wait> flag and specify a period of time (for example, 1h) to allocate more time for the deployment of applications.
Verify Installation
Once the Konvoy cluster is built and Kommander has been installed, you will want to verify your installation of Kommander in that section of documentation.
