Kubernetes (Jun 2014, Google trends) is an open-source Container-Orchestration system for automating deployment, autoscaling (based on CPU, memory[1] or custom metrics[2]) and management of containerized applications.[4] Kubernetes works with Docker, containerd, and CRI-O.

Kubernetes objects, concepts or subsystems:

Installation

See: Kubernetes installation and Kubernetes changelog/releases.

Tools

Information

Microk8s

MicroK8s single node Kubernetes solution available since December 2018[3]

  • Installation:

Kubernetes log files [4]

Kubernetes Ports

See also OpenShift port requeriments: https://docs.openshift.com/container-platform/4.2/installing/installing_bare_metal/installing-bare-metal.html

Products

Activities

Kubernetes Cloud Service Providers

Kubernetes is offered as a service on multiple public clouds, including Amazon Web Services (EKS)[6] (since June 2018 in the US East (N. Virginia) and US West (Oregon) Regions), Microsoft Azure (AKS) since october 2017,[7] DigitalOcean[8] (since May 2018),[9][10] Google Kubernetes Engine (GKE) in Google Cloud Platform[11] (at least since November 2014),[12] IBM Cloud [13], Alibaba Cloud [14], Mail.Ru Cloud Solutions (since May 2018)[15] and Oracle Kubernetes Service. For a more comprehensive list you can check https://kubernetes.io/docs/setup/pick-right-solution/#hosted-solutions. Most of them if not all requires a valid credit card.

Kubernetes Timeline

Kubernetes adoption

  • August 16 2017: Github runs on Kubernetes: all web and API requests are served by containers running in Kubernetes clusters deployed on metal cloud.
