From 159c5d177bf6f0caf1efb85b850b200ac7043c49 Mon Sep 17 00:00:00 2001 From: Cleber Rosa Date: Fri, 9 Jul 2021 15:29:27 +0100 Subject: Jobs based on custom runners: build environment docs and playbook To run basic jobs on custom runners, the environment needs to be properly set up. The most common requirement is having the right packages installed. The playbook introduced here covers the QEMU's project s390x and aarch64 machines. At the time this is being proposed, those machines have already had this playbook applied to them.

Create an ``inventory`` file +under ``scripts/ci/setup``, such as this:: + + fully.qualified.domain + other.machine.hostname + +You may need to set some variables in the inventory file itself. One +very common need is to tell Ansible to use a Python 3 interpreter on +those hosts. This would look like:: + + fully.qualified.domain ansible_python_interpreter=/usr/bin/python3 + other.machine.hostname ansible_python_interpreter=/usr/bin/python3 + +Build environment +~~~~~~~~~~~~~~~~~ + +The ``scripts/ci/setup/build-environment.yml`` Ansible playbook will +set up machines with the environment needed to perform builds and run +QEMU tests. This playbook consists on the installation of various +required packages (and a general package update while at it). It +currently covers a number of different Linux distributions, but it can +be expanded to cover other systems. + +The minimum required version of Ansible successfully tested in this +playbook is 2.8.0 (a version check is embedded within the playbook +itself). To run the playbook, execute:: + + cd scripts/ci/setup + ansible-playbook -i inventory build-environment.yml + +Please note that most of the tasks in the playbook require superuser +privileges, such as those from the ``root`` account or those obtained +by ``sudo``. If necessary, please refer to ``ansible-playbook`` +options such as ``--become``, ``--become-method``, ``--become-user`` +and ``--ask-become-pass``. -- cgit v1.2.3-55-g7522
