Posted by jpluimers on 2018/07/23

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!).

Notes

  • 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

    targetDevice="disk9"
    imageName="2017-11-29-raspbian-stretch-lite"
    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}"

jessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”

Posted by jpluimers on 2017/12/31

This is what DevOps is all about: [WayBackjessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”

I had seen the tweet before, but forgot to save it. Jonas Bandi reminded me of it at [WayBackWeekend Reader: End of Year Edition – reality-loop.

Jessie is doing great work. For instance, she developed and published contained.af, and nobody captured the flag yet: [WayBack] jessie frazelle on Twitter: «A year ago I made contained.af and it’s launched over 128,000 containers & no one has retrieved the flag».

The game runs in a container, gives you console access and has a bunch of questions. Still need to dig deeper in it, as it is a fascinating set-up. If you like to try it:

Wishing you a year where nobody captures your flags (:

Must read: [WayBack] Some Thoughts on the Docker-Kubernetes Announcement – Scott’s Weblog – The weblog of an IT pro specializing in cloud computing, virtualization, and networking, all with an open source view
