v0.2.2

Merge pull request #84 from cybozu-go/bump-0.2.2

Bump version to 0.2.2

v0.2.1

This release is to support Kubernetes 1.16.

v0.2.0

We are very proud to announce the new TopoLVM version 0.2.0!

Our kudos to Matt Martin (@matthias50) who raised many issues in production usage.

Although there are a lot of new features, we tell the most important thing first.

This version breaks backward compatibility completely so existing deployments must be uninstalled.
We are sorry for the inconveniences. After 1.0.0, we will make sure to prepare migration paths.

To uninstall TopoLVM 0.1, do:

1. Delete all PVC (and Pod) using TopoLVM StorageClass.

2. Delete all TopoLVM StorageClass.

3. Delete cluster resources:

   $ kubectl delete mutatingwebhookconfigurations topolvm-hook
   $ kubectl delete ns topolvm-system
   $ kubectl delete clusterrolebindings,clusterroles \
       topolvm-system:csi-topolvm-controller topolvm-system:csi-topolvm-node topolvm-system:topolvm-hook
   $ kubectl delete crds logicalvolumes.topolvm.cybozu.com
   $ kubectl delete csidrivers topolvm.cybozu.com

Now let's see new features:

• Volumes and associated Pods are cleaned up after Node deletion (#53).
• Controller pod is now deployed using Deployment with leader election for better availability (#58).
• kubelet exports filesystem usage stats of TopoLVM volumes as Prometheus metrics (#62).
• Controller and node plugins implement health check (#61).

Programs and source code are heavily re-organized:

• csi-topolvm, a unified CSI plugin, is removed.
• topolvm-controller, a CSI controller plugin as well as custom Kubernetes controller, is added.
• topolvm-hook is merged into topolvm-controller and removed.
• topolvm-node is reconstructed as a CSI node plugin as well as a custom Kubernetes controller.
• lvmetrics is merged into topolvm-node and removed.

and 0.2.0:

Enjoy!

P.S. We expect PVC resizing with Kubernetes 1.16 support for the next release.
