We’re updating our Kubernetes staging clusters with CoreDNS, the new dns server that replaces KubeDNS. After an in-depth analysis and tests we’ve verified that the performance and the stability between the two solutions are almost identical. Here you can find more details on why we decided to move to CoreDNS.
We’re also taking the opportunity to add a new
StorageClass for our clusters called gp2-encrypted which allows you to create kms-encrypted volumes. The kms key used can be either the default one generated by AWS or a custom one specified with an ARN.
apiVersion: v1 kind: PersistentVolume metadata: name: pv0001 spec: capacity: storage: 5Gi volumeMode: Filesystem accessModes: - ReadWriteOnce persistentVolumeReclaimPolicy: Recycle storageClassName: gp2-encrypted
If we don’t uncover any issues in the staging clusters during the next few days, we’ll rollout the upgrade to all the production clusters next week.
