Been getting lots of 503 errors (in CI) for https://github.com/k3d-io/k3d/releases/latest for about 30 minutes. When I checked Github status there was nothing there. The incident was only declared 7min ago - and only for issues. Late and not broad enough. Update: Now everything is yellow https://www.githubstatus.com/incidents/xntfc1fz5rfb

Only on mac though, because docker has extra overhead due to running on a vm there. I run kubernetes all the time in my linux desktop and it consume <5% cpu on idle, and that's with more than a dozen pods running in the background (postgres, postgis, mysql, redis, memcached, a bunch of django webapps, some test wordpress instances, multiple sftp instances, and a pihole instance). I got fed up with the performance on mac and tried using https://github.com/rancher/k3d instead, which seems to cut the idle cpu usage by half.

In Kubernetes at Home with K3s

There are a number of resources that may be useful for your curriculum for this project listed in "Is there a program like codeacademy but for learning sysadmin?" https://news.ycombinator.com/item?id=19469266 : > [ http://www.opsschool.org/ , https://github.com/kahun/awesome-sysadmin/blob/master/README... , https://github.com/stack72/ops-books , https://landing.google.com/sre/books/ , https://response.pagerduty.com/ (Incident Response training)] To that I'd add that K3D (based on K3S, which is now a CNCF project) runs Kubernetes (k8s) in Docker containers. https://github.com/rancher/k3d For zero-downtime (HA: High availability) deployments, "Zero-Downtime Deployments To a Docker Swarm Cluster" describes Rolling Updates and Blue-Green Deployments; with illustrations: https://github.com/vfarcic/vfarcic.github.io/blob/master/doc...

-push style deployment with more of a least privileges approach (which also has more moving parts) you could take a look at: https://github.com/dokku/dokku-scheduler-kubernetes#function... And also reference ansible molecule and testinfra for writing sysadmin tests and the molecule vagrant driver for testing docker configurations. https://www.jeffgeerling.com/blog/2018/testing-your-ansible-... https://molecule.readthedocs.io/en/latest/ https://testinfra.readthedocs.io/en/latest/ : > With Testinfra you can write unit tests in Python to test actual state of your servers configured by management tools like Salt, Ansible, Puppet, Chef and so on. > Testinfra aims to be a Serverspec equivalent in python and is written as a plugin to the powerful Pytest test engine.

In Show HN: Linux sysadmin course, eight years on

abatilo·Aug 16, 2020

There are a lot of projects these days that aim to use Kubernetes as a docker-compose environment. I personally use http://skaffold.dev/ with either a local Kubernetes cluster built with https://github.com/rancher/k3d or https://github.com/kubernetes-sigs/kind. I think there's a very easy argument to be made that says that running K8s locally is overkill, but what I will say is that if you run your applications locally in K8s, that's one step closer to having your local environment mirror the production environment. Couple that with things like running https://github.com/localstack/localstack locally and you get even closer.

[k3d](https://github.com/rancher/k3d) runs k3s in docker. k3d is more lightweight than kind.

In Kind - run local Kubernetes clusters using Docker

darren0·Nov 27, 2019

Disclaimer: k3s creator Kind is intended to be a development tool to run fully upstream clusters using kubeadm in Docker containers. k3s is a custom distro that is oriented towards lightweight environments. The scope of k3s and kind are different (distro vs tool to run k8s in docker). There is another project called k3d (https://github.com/rancher/k3d) that more directly compares to kind. k3d will run k3s clusters in Docker. k3d creates clusters significantly faster and uses less mem/cpu resources than kind.
