Example Nginx (> 1.9) configuration for adding cross-origin resource sharing (CORS) support to reverse proxied APIs. Handle error status (4xx, 5xx) and expose headers.
#
# CORS header support
#
# One way to use this is by placing it into a file called "cors_support.conf"
# under your Nginx configuration directory and placing the following
# statement inside your location block(s):
#
# include cors_support.conf;
#
# A limitation to this method is that Nginx doesn't currently send headers

Install a Server Certificate For oVirt Manager UI

openssl req -new -sha256 -key /etc/pki/ovirt-engine/keys/apache.key.nopass -out /tmp/engine.csr
  • Submit the CSR to the issuer and wait. Or, if you are the issuer and you happen to be using FreeIPA/IdM, you may issue the certificate with ipa-admintools. For example,

RPM build and hosting workflow using github, travis-ci and copr

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.
