A major vulnerability was discovered in Kubernetes: CVE-2018-1002105

The vulnerability was widely publicized giving credence to its severity.

The remediation is to simply use a patched version:

  • v1.10.11
  • v1.11.5
  • v1.12.3
  • v1.13.0-rc.1

Our Helm chart docs require Kubernetes 1.8+. We should require 1.10+ (or possibly 1.10.11+). Although not technically required (e.g. the chart will run on 1.8) we should require 1.10 since earlier versions are insecure.

Proposal

  1. Update the helm chart docs to say A Kubernetes cluster, version 1.10 or higher. 6vCPU and 16GB of RAM is recommended. under requirements.
  2. Search for additional K8s-related docs that speckfy a version number and make sure the version is 1.10+
