AWS Air-gapped FIPS: Install Kommander

You have installed the Konvoy component and created a cluster. Now it is time to Install Kommander which will allow you to access the UI and attach new or existing clusters to monitor.

Prerequisites

• Ensure you have reviewed all Prerequisites for Install.

• Ensure you have a default StorageClass.

• Ensure you have loaded all necessary images for your configuration. See load the images into your registry .

• Note down the name of the cluster, where you want to install Kommander. If you do not know it, use kubectl get clusters -A to display it.

Create your Kommander Installer Configuration File

1. Set the environment variable for your cluster:

   CODE

   export CLUSTER_NAME=<your-management-cluster-name>

2. Copy the kubeconfig file of your Management cluster to your local directory:

   CODE

   dkp get kubeconfig -c ${CLUSTER_NAME} >> ${CLUSTER_NAME}.conf

3. Create a configuration file for the deployment:

   CODE

   dkp install kommander --init --airgapped > kommander.yaml

4. If required: Customize your kommander.yaml.
   See Kommander Additional Install Configurations for customization options. Some of them include:
   Custom Domains and Certificates, HTTP proxy, External Load Balancer, GPU utilization, Rook Ceph customization (Pre-provisioned envs), etc.

5. If required: If your cluster uses a custom AWS VPC and requires an internal load-balancer, set the traefik annotation to create an internal-facing ELB:

   CODE

   apps:
     traefik:
       enabled: true
       values: |
         service:
           annotations:
             service.beta.kubernetes.io/aws-load-balancer-internal: "true"

Enable DKP Catalog Applications and Install Kommander

If you have an Enterprise license and would like to use the DKP Catalog Applications function, follow these steps:

1. In the same kommander.yaml of the previous section, add these values for dkp-catalog-applications:

   CODE

   apiVersion: config.kommander.mesosphere.io/v1alpha1
   kind: Installation
   catalog:
     repositories:
       - name: dkp-catalog-applications
         labels:
           kommander.d2iq.io/project-default-catalog-repository: "true"
           kommander.d2iq.io/workspace-default-catalog-repository: "true"
           kommander.d2iq.io/gitapps-gitrepository-type: "dkp"
         gitRepositorySpec:
           url: https://github.com/mesosphere/dkp-catalog-applications
           ref:
             tag: v2.5.0

   If you only want to enable catalog applications to an existing configuration, add these values to an existing installer configuration file to maintain your Management cluster’s settings.

2. Use the customized kommander.yaml to install DKP:

   CODE

   dkp install kommander --installer-config kommander.yaml --kubeconfig=${CLUSTER_NAME}.conf \
   --kommander-applications-repository ./application-repositories/kommander-applications-v2.5.0.tar.gz \
   --charts-bundle ./application-charts/dkp-kommander-charts-bundle-v2.5.0.tar.gz \
   --charts-bundle ./application-charts/dkp-catalog-applications-charts-bundle-v2.5.0.tar.gz

Tips and recommendations

• The --kubeconfig=${CLUSTER_NAME}.conf flag ensures that you install Kommander on the correct cluster. For alternatives, see (Provide Context for Commands with a kubeconfig File .

• Applications can take longer to deploy, and time out the installation. Add the --wait-timeout <time to wait> flag and specify a period of time (for example, 1h) to allocate more time to the deployment of applications.

• If the Kommander installation fails, or you wish to reconfigure applications, rerun the install command to retry.
