Mirroring images

This follows the documentation for mirroring images.

1. Download the images

   • Use dryrun.sh to get the `ImageContentSourcePolicy`` needed for the disconnected cluster.

The values used for the destination registry, which are used for the ICSP, can be arbitrary and changed on the disconnected network to represent your scenario. This is useful if the hostnames / IPs are sensitive.

ETHERNET ADAPTOR HARDWARE ADDRESS REQUIREMENTS
When provisioning VMs for the cluster, the ethernet interfaces configured for each VM must use a MAC address from the VMware Organizationally Unique Identifier (OUI) allocation ranges:

00:05:69:00:00:00 to 00:05:69:FF:FF:FF

00:0c:29:00:00:00 to 00:0c:29:FF:FF:FF

Overview: running crc on a remote server

This document shows how to deploy an OpenShift instance on a server using CodeReady Containers (crc) that can be accessed remotely from one or more client machines (sometimes called a "headless" instance). This provides a low-cost test and development platform that can be shared by developers. Deploying this way also allows a user to create an instance that uses more cpu and memory resources than may be available on his or her laptop.

While there are benefits to this type of deployment, please note that the primary use case for crc is to deploy a local OpenShift instance on a workstation or laptop and access it directly from the same machine. The headless setup is configured completely outside of crc itself, and supporting a headless setup is beyond the mission of the crc development team. Please do not ask for changes to crc to support this type of deployment, it will only cost the team time as they politely decline :)

The instructions here were tested with F

walkthrough: buildah on knative

The buildah utility is a versitile container build tool that does not require a daemon (everything is direct invocation). See my "deep dive" for a few hands on use-cases.

Recently knative was announced. It is a project to enable the kubernetes primitives needed to build a functions-as-a-service. There are a plumbing services needed around this use-case, "build" is one of them. Building containers is largely an indepenent goal and story of "serverless" or "FaaS", but I get why they are grouped together.

Kubernetes on DigitalOcean with CoreOS

Let's look at an example of how to launch a Kubernetes cluster from scratch on DigitalOcean, including kubeadm, an Nginx Ingress controller, and Letsencrypt certificates.

Overview

Environment

We'll be creating a four-node cluster (k8s-master, k8s-000...k8s-002), load balancer, and ssl certificates.
