GCP: 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.
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
Set the environment variable for your cluster:
CODEexport CLUSTER_NAME=<your-management-cluster-name>
Copy the
kubeconfig
file of your Management cluster to your local directory:CODEdkp get kubeconfig -c ${CLUSTER_NAME} >> ${CLUSTER_NAME}.conf
Create a configuration file for the deployment:
CODEdkp install kommander --init > kommander.yaml
If required: Customize your
kommander.yaml
.
See Kommander Customizations for customization options. Some of them include:
Custom Domains and Certificates, HTTP proxy, External Load Balancer, GPU utilization, Rook Ceph customization (Pre-provisioned envs), etc.
Enable DKP Catalog Applications and Install Kommander
If you want to enable DKP Catalog applications after installing DKP, see Enable DKP Catalog Applications after Installing DKP.
In the same
kommander.yaml
of the previous section, add these values fordkp-catalog-applications
:CODEapiVersion: config.kommander.mesosphere.io/v1alpha1 kind: Installation catalog: repositories: - name: dkp-catalog-applications labels: kommander.d2iq.io/project-default-catalog-repository: "true" kommander.d2iq.io/workspace-default-catalog-repository: "true" kommander.d2iq.io/gitapps-gitrepository-type: "dkp" gitRepositorySpec: url: https://github.com/mesosphere/dkp-catalog-applications ref: tag: v2.6.1
If you only want to enable catalog applications to an existing configuration, add these values to an existing installer configuration file to maintain your Management cluster’s settings.
Use the customized
kommander.yaml
to install DKP:CODEdkp install kommander --installer-config kommander.yaml --kubeconfig=${CLUSTER_NAME}.conf
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.
