Two bootstrap issues are fix: one on k8s and the other on arm64, plus an intermittent situation where container creation can fail. There’s also a dashboard fix. 🛠️ Fixes (more on the milestone): - Provisioner worker pool errors cause on-machine provisioning to cease ([LP#1994488](https://bugs.launchpad.net/bugs/1994488)) - charm container crashes resulting in storage-attach hook error ([LP#1993309](https://bugs.launchpad.net/bugs/1993309)) - not able to bootstrap juju on arm64 with juju 3.0 ([LP#1994173](https://bugs.launchpad.net/bugs/1994173)) See the full list in the [milestone page](https://launchpad.net/juju/+milestone/3.0.2). ### 🔸 **Juju 3.0.0** - 22 Oct 2022 #### What’s Changed ##### CLI Changes **Commands that have been added:** ```text juju list-operations juju list-secrets juju operations juju secrets juju show-operation juju show-secret juju show-task juju wait-for ``` **Commands that have been renamed:** ```text juju constraints (replaces get-constraints) juju integrate (replaces add-relation, relate) juju model-constraints (replaces get-model-constraints) juju set-application-base (replaces set-series) juju upgrade-machine (replaces upgrade-series) juju sync-agent-binary (replaces sync-tools) juju refresh (replaces upgrade-charm) juju exec (replaces juju run) juju run (replaces juju run-action) ``` **Commands that have been dropped:** ```text juju add-subnet juju attach juju budget juju cached-images juju cancel-action juju charm juju create-wallet juju gui juju hook-tool juju hook-tools juju list-cached-images juju list-plans juju list-wallets juju plans juju remove-cached-images juju run-action juju set-plan juju set-wallet juju show-action-output juju show-action-status juju show-status juju show-wallet juju sla juju upgrade-dashboard juju upgrade-gui juju wallets ``` ##### Removal of Juju GUI Juju GUI is no longer deployed and the –no-gui flag was dropped from juju bootstrap. The Juju Dashboard replaces the GUI and is deployed using the juju-dashboard charm. ##### Windows charms no longer supported Windows charms are no longer supported. ##### Bionic and earlier workloads no longer supported Only workloads on focal and later are supported. ##### No longer create default model on bootstrap Running juju bootstrap no longer creates a default model. After bootstrap you can use add-model to create a new model to host your workloads. ##### add-k8s helpers for aks, gke, eks The Juju add-k8s command no longer supports the options “–aks”, “–eks”, “–gke” for interactive k8s cloud registration. The strict snap cannot execute the external binaries needed to enable this functionality. The options may be added back in a future update. Note: it’s still possible to register AKS, GKE, or EKS clusters by passing the relevant kube config to add-k8s directly. ##### Deprecated traditional kubernetes charms Traditional kubernetes charms using the pod-spec charm style are deprecated in favor of newer sidecar kubernetes charms. From juju 3.0, pod-spec charms are pinned to Ubuntu 20.04 (focal) as the base until their removal in a future major version of juju. ##### Rackspace and Cloudsigma providers no longer supported Rackspace and Cloudsigma providers are no longer supported #### What’s New ##### Juju Dashboard replaces Juju GUI The Juju Dashboard replaces the GUI; it is deployed via the juju-dashboard charm, which needs to be integrated with the controller application in the controller model. ```default juju bootstrap juju switch controller juju deploy juju-dashboard juju integrate controller juju-dashboard juju expose juju-dashboard ``` After the juju-dashboard application shows as active, run the dashboard command: `juju dashboard` **Note:** the error message which appears if the dashboard is not yet ready needs to be fixed. ([https://bugs.launchpad.net/juju/+bug/1994953](https://bugs.launchpad.net/juju/+bug/1994953)) ##### Actions The client side actions UX has been significantly revamped. See the doc here: [https://juju.is/docs/olm/manage-actions](https://juju.is/docs/olm/manage-actions) To understand the changes coming from 2.9 or earlier, see the post here: [https://discourse.charmhub.io/t/juju-actions-opt-in-to-new-behaviour-from-juju-2-8/2255](https://discourse.charmhub.io/t/juju-actions-opt-in-to-new-behaviour-from-juju-2-8/2255) ##### Secrets It is now possible for charms to create and share secrets across relation data. This avoids the need for sensitive content to be exposed in plain text. The feature is most relevant to charm authors rather than end users, since how charms use secrets is an internal implementation detail for how workloads are configured and managed. Nonetheless, end users can inspect secrets created by deployed charms: [https://juju.is/docs/olm/secret](https://juju.is/docs/olm/secret) [https://juju.is/docs/olm/manage-secrets](https://juju.is/docs/olm/manage-secrets) Charm authors can learn how to use secrets in their charms: [https://juju.is/docs/sdk/add-a-secret-to-a-charm](https://juju.is/docs/sdk/add-a-secret-to-a-charm) [https://juju.is/docs/sdk/secret-events](https://juju.is/docs/sdk/secret-events) ##### Juju controller application The controller model has a Juju controller application deployed at bootstrap. This application currently provides integration endpoints for the Juju dashboard charm. Future work will support integration with the COS stack and others. ##### MongoDB server-side transactions now default Since the move to mongo 4.4 in juju 2.9, juju now uses server-side transactions. #### Fixes 🛠️ - deploy k8s charms to juju 3.0 beta is broken ([LP1947105](https://bugs.launchpad.net/bugs/1947105)) - Juju bootstrap failing with various Kubernetes ([LP1905320](https://bugs.launchpad.net/bugs/1905320)) - bootstrapping juju installs ‘core’ but ‘juju-db’ depends on ‘core18’ ([LP1920033](https://bugs.launchpad.net/bugs/1920033)) - bootstrap OCI cloud fails, cannot find image.
