AWS Air-gapped GPU: Verify Install and Log in the UI

Once the Konvoy cluster is built and Kommander has been installed, you will want to verify your installation of Kommander. After the CLI successfully installs the components, it will wait for all applications to be ready by default.

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

If you prefer the CLI to not wait for all applications to become ready, you can set the --wait=false flag.

If you choose not to wait via the DKP CLI, you can check the status of the installation using the following command:

CODE

kubectl -n kommander wait --for condition=Released helmreleases --all --timeout 15m

This will wait for each of the helm charts to reach their Released condition, eventually resulting in an output resembling below:

CODE

helmrelease.helm.toolkit.fluxcd.io/centralized-grafana condition met
helmrelease.helm.toolkit.fluxcd.io/dex condition met

Failed HelmReleases

If any application fails to successfully deploy, you can check the status of a HelmRelease with:

CODE

kubectl -n kommander get helmrelease <HELMRELEASE_NAME>

If you find any HelmReleases in a “broken” release state such as “exhausted” or “another rollback/release in progress”, you can trigger a reconciliation of the HelmRelease using the following commands:

CODE

kubectl -n kommander patch helmrelease <HELMRELEASE_NAME> --type='json' -p='[{"op": "replace", "path": "/spec/suspend", "value": true}]'
kubectl -n kommander patch helmrelease <HELMRELEASE_NAME> --type='json' -p='[{"op": "replace", "path": "/spec/suspend", "value": false}]'

Log in to the UI

By default, you can log in to the UI in Kommander with the credentials given using this command:

CODE

dkp open dashboard --kubeconfig=${CLUSTER_NAME}.conf

You can also retrieve your credentials at any time using the following command:

CODE

kubectl -n kommander get secret dkp-credentials -o go-template='Username: {{.data.username|base64decode}}{{ "\n"}}Password: {{.data.password|base64decode}}{{ "\n"}}'

You can also retrieve the URL used for accessing the UI using the following command:

CODE

kubectl -n kommander get svc kommander-traefik -o go-template='https://{{with index .status.loadBalancer.ingress 0}}{{or .hostname .ip}}{{end}}/dkp/kommander/dashboard{{ "\n"}}'

You should only use these static credentials to access the UI for configuring an external identity provider. Treat them as back up credentials rather than use them for normal access.

You rotate the password using the following command:

CODE

dkp experimental rotate dashboard-password
Password: kqZ31lMBSCLcBjUKVwLJMQL2PxalipIzZw5Pjyw09wDqjWV3dz2wPSSBYi09JGJp

You can perform the following operations on Identity Providers:

Create an Identity Provider
Temporarily Disable an Identity Provider
Create Groups

Dashboard UI Functions

After installing Konvoy component and building a cluster as well as successfully installing Kommander and logging into the UI, you are now ready to customize configurations using the Day 2 Cluster Operations Management section of the documentation. The majority of this customization such as attaching clusters and deploying applications will take place in the dashboard or UI of DKP. The Day 2 section allows you to manage cluster operations and their application workloads to optimize your organization’s productivity.

For more GPU information, see the section for GPU under Day 2 - Cluster Operations Management.
