Thinkfan Configuration Notes

This are notes for configuration thinkfan for Fedora. This configuration procedure was followed on a Lenovo Thinkpad X1 Carbon (5th Gen) running Fedora 25.

Non standard (default) configuration was required for this machine as the default sensors are not available. Eg: /proc/acpi/ibm/thermal does not exist for this model.

An annoted configuration file has been included below. However, there is no guarentee that this will work as-is on every machine.

Installation

dnf -y install thinkfan

jq '.spec.triggers |= map(select(contains({"type": "ImageChange"}) | not))'

OpenShift Debugging: S2I Build Failures

Notes for debugging s2i build issues locally without having to run through the change-push-build model and to allow for some flexibility when debugging. This helps in identifying any issues in the application build process or incompatibilities with any of the s2i stages.

Requirements

1. You have docker, s2i and openshift-cli installed locally.
2. openshift-cli is logged in to the correct cluster.

Prepare Docker Repository Access

OpenShift Developer Cluster on OSX

This document details how to bring up an OpenShift local cluster on Mac OSX. We also detail how to do the same under a proxied environment.

System Requirements

1. Docker for Mac (stable). Note that this will also work with Docker Toolbox for Mac, however this is untested and could have issues with networking.
2. Homebrew package manager for macOS. If you are installing from behind a proxy, use the script available at this gist.

Install OpenShift CLI

The openshift-cli can be installed via homebrew. This package provides us with the oc binary.

#!/usr/bin/env bash
# Based on: http://godlessheathenmemoirs.blogspot.com.au/2015/03/homebrew-aka-brew-on-mac-os-x-behind.html

function usage() {
  echo 2>&1 ""
  echo 2>&1 "usage: $(basename $0) PROXY_HOST PROXY_PORT"
  exit 1
}

PROXY_HOST=${PROXY_HOST:-$1}

RPM Build Flow

This document details a simple RPM build flow pattern used to build and host RPM artifacts for open source projects. The below is a visual summary of this flow.

In order to achieve this multiple tools and services are used. The services and their purpose in the flow is as listed below.

Service	Purpose
GitHub	As is the most common use for GitHub, it holds the build source code. In this case we hold only the spec files and related source files. All other sources, including project binaries/sources are retrieved at build time.
