Liqo Dashboard

LiqoDash is a web-based UI for Liqo. It allows you to visualize and control all the Liqo components, as well as manage the status of the Liqo system itself. You can use LiqoDash to get a general overview of your Liqo resources (both local and remote), see the connected and available peers and start new peerings. Finally, it allows also to create and modify CRDs using either a built-in YAML/JSON editor or a dynamically generated CRD wizard.

LiqoDash also provides information about the state of your cluster and all other clusters you are connected to.

Dashboard-UI example

Installing LiqoDash

LiqoDash is installed by default during the installation of Liqo and it is bound to the API server of the cluster where Liqo has been installed.

Accessing LiqoDash


In order to access the dashboard you need to first get the port on which LiqoDash is exposed, which can be done with the following command:

kubectl -n liqo describe service liqo-dashboard | grep NodePort

Which will output:

Type:          NodePort
NodePort:      https  32421/TCP

In this case, the dashboard has been exposed to the port 32421 Now, you can access LiqoDash using your master node IP and the service port you just found: https://<MASTER_IP>:<LIQODASH_PORT>

NOTE: to get your master node IP, you can run kubectl get nodes -o wide | grep master, and take the INTERNAL-IP


A simple way to access the dashboard with a simpler URL than the one specified above is to use kubectl port-forward.

kubectl port-forward -n liqo service/liqo-dashboard 6443:443

To access LiqoDash you can go to:


NOTE: The PORT exposed with the port forward, that in the example is 6443, can be any PORT that is not already used.


LiqoDash can also be exposed using an Ingress. You must have an Ingress controller for an Ingress resource to work. If you have one, you can specify the desired host name exporting the variable DASHBOARD_INGRESS before installing Liqo, for example:


Once installed, you can see that an Ingress resource is created:

kubectl get -n liqo ingress

You can access the dashboard through the provided host name.

Security certificates

For security reasons, LiqoDash runs over HTTPS, which means that a Certificate is needed to establish the TLS connection. An x509 self-signed Certificate is generated when the dashboard is deployed, and must be accepted by your browser in order to establish the TLS connection.

The first time you access LiqoDash, it is likely that your browser will show you a warning that you are trying to access a website that uses a self-signed certificate, and thus it is not trusted by default. Simply accept the risk and continue to access the dashboard.

If you are exposing LiqoDash through an Ingress, you can either use a certificate provided by a public trusted Certificate Authority (like Let’s encrypt) or a self-signed one.

Differences between access methods

When to use Port-Forward

Using kubectl port-forward to access the dashboard service is usually meant for testing/debugging purposes. It is not a long term solution, as it require to always run the port-forward and keep it active. However, if you just want to access the dashboard via localhost, this is the easiest method.

When to use NodePort

Using a NodePort means that a specific port is opened on all the Nodes, and traffic sent to this port is forwarded to a service (in this case the dashboard). It is not recommended to use this method to directly expose a service on the internet, but if you are going to use the dashboard on the same machine your cluster is, that is a simple and valid solution.

When to use Ingress

Using Ingress is probably the best way to expose LiqoDash, especially if you want to access it through the internet. It can provide load balancing, SSL termination and name-based hosting, letting you access the dashboard using a host name instead of just its IP. Because there many types of Ingress controllers, each one with different capabilities, it may require some work to properly set up.


Login with Bearer Token

For security, LiqoDash requires a Bearer Token to log in. This token is stored within a secret, which is created by default during the installation, along with a service account and a cluster role binding.

To find the token to use to log in, run the following:

kubectl -n liqo describe secret $(kubectl -n liqo get secret | grep liqodash | awk '{print $1}')

which should print something like this:

Name:         liqodash-admin-sa-token-94v8x
Namespace:    liqo
Labels:       <none>
Annotations: liqodash-admin-sa


ca.crt:     1025 bytes
namespace:  4 bytes
token:      eyJhbGciOiJSUzI1NiIsImtpZCI6Img0d3lBRjRGWTlYbndfcnZFeWNQR2VQX3dRVjhfXzBVLTdlTG95Tm9QMW8ifQ.eyJpc3MiOiJrdWJlcm5ldGVzL3NlcnZpY2VhY2NvdW50Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9uYW1lc3BhY2UiOiJsaXFvIiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZWNyZXQubmFtZSI6ImxpcW9kYXNoLWFkbWluLXNhLXRva2VuLTk0djh4Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZXJ2aWNlLWFjY291bnQubmFtZSI6ImxpcW9kYXNoLWFkbWluLXNhIiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZXJ2aWNlLWFjY291bnQudWlkIjoiYWQ0MjFiNjgtN2NhNS00ZjJiLTkwMjItNDU0ZWI0MmY4ODBkIiwic3ViIjoic3lzdGVtOnNlcnZpY2VhY2NvdW50OmxpcW86bGlxb2Rhc2gtYWRtaW4tc2EifQ.ZX4SgxepLjDWMYtvlWUfR3Qjzhf80Jq-17JzF7DSZVMJKvqgah0JIG9Ieqj6DBQr-0xxWnTW6hosNjcdf6pm62SbuiSMwyE3xS_j3dAmCQHx5umGbnTjp6GUaMu8JiFtajOpU7-9f06W5g4I44LF1-3FwgG3OY6vVdL6CypWfjumwgh_yLKE9h7tjKl8CiSfNuLVDWHL4l07W9fEeed8lNmFg4FlvOVHmFglTjz20VKEeu964pNlgK0MRGo_cVnDJyWl7cdeEmR0qfiPup5AMQLWUvlX9RTB7UTiRyw9YYZXPrsX5sdUMVuWb-G9ZQ8eABQI7BAs4uCouuoWmIDzag

Now, (1) copy the token, (2) paste it in the login screen, and (3) sign in.

NOTE: the LiqoDash Service Account has admin privileges. To find out more about permissions in Kubernetes read the official authentication and authorization documentation.

Login with OIDC

If you have an OIDC provider available in your cluster (such as Keycloak), you can use it to access the dashboard and bypass the standard login with the token. In order to bind the dashboard with you OIDC provider, you have to edit the dashboard configmap, which represents the structure that contains the Dashboard configuration. To do so, run the following command:

kubectl edit -n liqo configmap liqo-dashboard-configmap

You should see a YAML representation of the configmap, such as the following:

# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
apiVersion: v1
  name: liqo-dashboard-configmap
  namespace: liqo
  resourceVersion: "012345"
  selfLink: /api/v1/namespaces/liqo/configmaps/liqo-dashboard-configmap
  uid: 8e48f478-993d-11e7-87e0-901b0e532516
  oidc_client_id: ""
  oidc_client_secret: ""
  oidc_provider_url: ""
  oidc_redirect_uri: ""
kind: ConfigMap

Change the values under data and save the file. Then, restart the dashboard:

kubectl rollout restart deployment liqo-dashboard -n liqo

From now on, any attempt to login will be redirected to your OIDC provider for the authentication.

NOTE: you can always revert to the token login authentication by editing the configmap.

Metrics Integration

One of the key feature of LiqoDash is to show the real time status of your cluster (in terms of cpu and memory), as well as the other clusters you are connected to. In order to show the actual consumption of resources you need to have a metrics server running in your cluster. Otherwise, LiqoDash will consider every resource consuming so much cpu and memory as specified in the request parameter of that resource (if specified).

You can install a metrics server following the official documentation. The easiest way to check if metrics-server is installed and working properly is to run kubectl top pod or kubectl top node.
