Introducing Charmed Temporal 1.23

The Workflows team is proud to announce the release of the first supported version of Charmed Temporal, now available to deploy from 1.23/stable.

What’s new

Highlights

• 1.23 is the first supported version of the Charmed Temporal solution.
• Documentation improvements
  • Revamped Charmed Temporal Tutorial: updated for 1.23/stable on ubuntu@24.04, with the new temporal-host-info relation, the renamed cli action on the admin charm, deprecation notes for server-name and host configs, and a worker page that covers both same-model and cross-model deployment paths.
  • New How to Configure the Temporal Worker: covers the full worker config surface (server connection, environment variables, authentication, Vault, TLS, Sentry, PostgreSQL).
  • New latest/stable → 1.23/stable upgrade guide.
• New temporal-host-info relation between temporal-k8s and the admin / UI / worker charms to discover the Temporal frontend.

Upgrades

• All Temporal charms run on Ubuntu 24.04 LTS:
  • temporal-k8s #122 - Migrate to Ubuntu 24.04
  • temporal-admin-k8s #49 - Migrate to Ubuntu 24.04
  • temporal-ui-k8s #45 - Migrate to Ubuntu 24.04
  • temporal-worker-k8s #94 - Migrate to Ubuntu 24.04 (track 1.0)

Features

• Enhanced security by integrating the following rocks:

  • temporal-server - temporal-k8s #82 - Update charm to use temporal-server rock
  • temporal-admin - temporal-admin-k8s #35 - Update to 1.23 server rock
  • temporal-ui - temporal-ui-k8s #29 - Integrate with the newly published temporal ui rock

• New cli action on temporal-admin-k8s, replacing the deprecated tctl action.

  • Shipped as part of temporal-admin-k8s #35 - Update to 1.23 server rock

• New temporal-host-info relation between temporal-k8s and the admin / UI / worker charms. The relation is the supported way for those charms to discover the Temporal server frontend service; it is mandatory for temporal-ui-k8s and the supported mechanism for temporal-admin-k8s and temporal-worker-k8s. The pre-existing server-name config on temporal-admin-k8s (and the host config on temporal-worker-k8s) is deprecated and only used as a fallback when the relation is absent.

  • temporal-k8s #114 - feat: add temporal-host-info relation and charm library
  • temporal-admin-k8s #43 - temporal-host-info requirer
  • temporal-ui-k8s #39 - temporal-host-info requirer
  • temporal-worker-k8s #86 - Add temporal-worker-consumer and temporal-host-info relations (track 1.0)

• Traefik ingress for the UI - temporal-ui-k8s #43
