Update NOW! CVE-2018-1002105, with root access. ​Kubernetes’ first major security hole discovered | ZDNet

Posted by jpluimers on 2018/12/04

From [WayBack] ​Kubernetes’ first major security hole discovered | ZDNet in reverse order:

Fortunately, there is a fix, but some of you aren’t going to like it. You must upgrade Kubernetes. Now. Specifically, there are patched version of Kubernetes [WayBackv1.10.11,  [WayBack] v1.11.5, [WayBackv1.12.3, and [WayBackv1.13.0-rc.1.

[WayBack] Red Hat said, “The privilege escalation flaw makes it possible for any user to gain full administrator privileges on any compute node being run in a Kubernetes pod. [WayBackThis is a big deal. Not only can this actor steal sensitive data or inject malicious code, but they can also bring down production applications and services from within an organization’s firewall.”

And the bug, [WayBackCVE-2018-1002105, aka the Kubernetes privilege escalation flaw, is a doozy. It’s a [WayBackCVSS 9.8 critical security hole.

The Ridiculous Bandwidth Costs of Amazon, Google and Microsoft Cloud Computing – Arador

Posted by jpluimers on 2018/10/26

In this article I compare the costs of network bandwidth transferred out of Amazon EC2, Google Cloud Platform, Microsoft Azure and Amazon Lightsail.

Bandwidth costs are one of the most ridiculously expensive components of cloud computing, and there are some serious inconsistencies in the industry, especially with Amazon.


If you move a significant amount of data you should think twice before moving to the cloud, these bandwidth prices are truly ridiculous and there’s no way they can be justified when compared to colocation facilities.

One day you will do containers.

If you want to know how k8n (Kubernetes) can help you with Docker containers, then read [WayBackThe Illustrated Guide to Kubernetes – The Isoblog. and watch the video below.

Very well explained!

Sometimes clouds vaporise: the Docker Cloud shuts down in ~8 weeks.

Posted by jpluimers on 2018/03/26

From [WayBackDocker – Docker Cloud Migration Notification and FAQs:

The services on Docker Cloud that provide application, node, and swarm cluster management will be shutting down on May 21.

If you do not migrate by May 21, your applications running on the Docker node cluster management service will cease to operate.

Swarms will continue to function; however, if you do not retrieve your SSH keys for the Swarms being managed by our swarm cluster management service, you will be unable to access your swarms using your Docker ID. For instructions on how to retrieve and access your Swarms with SSH keys, please refer to the Docker docs.

So soon, no more [WayBack] Docker Cloud – Build, Ship and Run any App, Anywhere.

Remember: still the cloud is other peoples computers, so be sure you can move when needed.

Scott Hanselman on Witter: “Why should I care about Kubernetes, Docker, and Container Orchestration?”

Posted by jpluimers on 2018/02/08

An important question for many people, so if you want to know more or get started: [WayBack] Scott Hanselman on Twitter: “Why should I care about Kubernetes, Docker, and Container Orchestration?” followed by:

Yes, AKS is Azure Container Services (go figure!).


  • For burning, Scott recommends [WayBack] Etcher: Burn images to SD cards & USB drives, safely and easily (which is now also available as experimental [WayBackEtcher CLI), I tended to use a script like below since I’m a command-line person, but since Etcher does write and verify in one run, I’m considering switching:
    1. find where the SD card is mounted on your Mac: diskutil list
    2. sudo su -
    3. execute this from the directory where you downloaded filling in targetDevice with the value from diskutil list

    unzip -o ${imageName}.zip
    diskutil umount "/dev/${targetDevice}s1"; \
    dd bs=1m of="/dev/r${targetDevice}" if=${imageName}; \
    sync; \
    diskutil list; \
    diskutil eject "/dev/${targetDevice}"
