canonical/microk8s最新发布版本:installer-v2.3.4(2023-10-23 22:28:51)
Featured in this release
cloudinit-like launch configurations
Users can now provide a yaml manifest describing how MicroK8s should be setup. Manifests may specify things like:
- which addons to be enabled,
- what cluster the node should join,
- what image and addon repositories should be used,
- what arguments should be used in bringing up the K8s services
MicroK8s consumes configuration manifests found in /root/snap/microk8s/common/ or passed as snap configuration argument via snap set microk8s config=”$(cat microk8s-config.yaml)”
as well as through a content interface.
Datastore - dqlite improvements
Optimizations in the queries that hit the datastore. This yields a sizable benefit in both latency and CPU utilization. Work on this area is still on-going so expect more improvements in the near future.
New partner and community addons
The following addons are new in the 1.27 release under the community repo:
- Shifu is a Kubernetes native, production-grade, protocol & vendor agnostic IoT development framework. The partnership with Shifu takes IoT and Edge devices with MicroK8s to the next level.
- EasyHAProxy automatically configures HA proxy as ingress based on the labels defined in deployed containers. An advantage of HA proxy is that it provides TCP endpoints and it works in tandem with the next addon.
- Parking deploys a static webserver to park a domain this involves setting up all necessary ingress, service and pods.
