Deploy Temporal Web UI

This is part of the Charmed Temporal Tutorial. Please refer to this page for more information and the overview of the content.

The Temporal Web UI is a user interface used to interact with and monitor Temporal workflows and activities.

Deploy and integrate

1. Deploy the Temporal User Interface (UI):

juju deploy temporal-ui-k8s --channel 1.23/stable --base ubuntu@24.04

1. Wait for the application to require its mandatory relations. The unit will report blocked with a message such as:

Unit                Workload  Agent  Address     Ports  Message
temporal-ui-k8s/0*  blocked   idle   10.1.0.111         temporal-host-info relation not established

1. Integrate with Temporal Server. The UI charm in 1.23/stable requires two relations to reach active:

juju integrate temporal-k8s:ui              temporal-ui-k8s:ui
juju integrate temporal-k8s:temporal-host-info  temporal-ui-k8s:temporal-host-info

The ui relation provides the routing and rendering bridge to the Temporal frontend. The temporal-host-info relation provides the frontend’s gRPC host and port. It is mandatory in 1.23/stable and the UI will remain blocked until it is integrated.

1. Wait for both charms to be active and idle. After integration, juju status --relations should list both relations:

Relation provider                 Requirer                          Interface
temporal-k8s:temporal-host-info   temporal-ui-k8s:temporal-host-info  temporal-host-info
temporal-k8s:ui                   temporal-ui-k8s:ui                  temporal

Access the UI on a web browser

Depending on the local configuration, the Temporal Web UI can be accessed using:

• The unit IP directly:

TEMPORAL_UI_IP=$(juju show-unit temporal-ui-k8s/0 | yq '.temporal-ui-k8s/0.address')

# In the browser
http://{TEMPORAL_UI_IP}:8080

• The ingress IP or DNS name: This requires extra configuration, see Configure Ingress with Nginx Ingress Integrator for more details.
