Description

Implements a Beaker hypervisor that makes hosts provisioned by the AlwaysBeScheduling service available to a Beaker run.

Installation

Beaker will automatically load the appropriate hypervisors for any given hosts file, so as long as your project dependencies are satisfied there's nothing else to do. No need to require this library in your tests.

As of Beaker 4.0, all hypervisor and DSL extension libraries have been removed and are no longer dependencies. In order to use a specific hypervisor or DSL extension library in your project, you will need to include them alongside Beaker in your Gemfile or project.gemspec. E.g.

# Gemfile
gem 'beaker', '~>4.0'
gem 'beaker-abs'
# project.gemspec
s.add_runtime_dependency 'beaker', '~>4.0'
s.add_runtime_dependency 'beaker-abs'

Beaker-abs changes the default beaker (core) behavior of settings the NET::SSH ssh config to 'false' which means do not respect any of the client's ssh_config. If beaker-abs detects that the ssh config will be false (it was not replaced in the option files, in the HOST config etc) it sets it to the value of SSH_CONFIG_FILE or default to 'true'. True means it will automatically check the typical locations (~/.ssh/config, /etc/ssh_config). Respecting the ssh_config is useful to specify things like no strict hostkley checking, and also to support the smallstep 'step' command in CI.

Usage

Create a beaker host config with hypervisor: abs, and pass the data from the AlwaysBeScheduling service in the ABS_RESOURCE_HOSTS environment variable to the beaker ABS hypervisor. For example, given a host config:

---
HOSTS:
  redhat7-64-1:
    hypervisor: abs
    platform: el-7-x86_64
    template: redhat-7-x86_64
    roles:
      - agent

Run beaker as:

env ABS_RESOURCE_HOSTS=<data> beaker --hosts hosts.yaml

Beaker will populate the vmhostname property for each host using information provided by the AlwaysBeScheduling service. This is typically used in a CI scenario, where the jenkins run-me-maybe plugin is populating the ABS_RESOURCE_HOSTS variable.

Using vmfloaty

If you do not specify a ABS_RESOURCE_HOSTS and request to provision via the beaker options, beaker-abs will fallback to using your vmfloaty configuration. By default it will look for the service named 'abs'. The name can also be configured via the environment variable ABS_SERVICE_NAME or the top level option in the hosts file abs_service_name. Similarly, the priority defaults to "1" which means it will take precedence over CI tests. Be careful not to run a CI test with this option. The priority can be configured via the environment variable ABS_SERVICE_PRIORITY or the top level option in the hosts file abs_service_priority.

Examples

Changing from default priority 1 to 3 via env var

ABS_SERVICE_PRIORITY=3 bundle exec beaker --provision --hosts=hosts.cfg --tests acceptance/tests

Changing the service name to look for in ~/.vmfloaty.yml via a beaker option file

$ cat options.rb
{
  provision: 'true',
  abs_service_name: "FOOBAR"
}
$ bundle exec beaker --hosts=hosts.cfg --tests acceptance/tests --options options.rb

Environment vars

Var Description Default
ABS_SERVICE_NAME When using locally via vmfloaty, the --service to use abs
ABS_SERVICE_PRIORITY When using locally via vmfloaty, the priority to use 1
SSH_CONFIG_FILE If beaker-abs detects the beaker default of 'false', you can specify a file location for the ssh_config. True means it will automatically check the typical locations (~/.ssh/config, /etc/ssh_config). true

Releasing

Open a release prep PR and run the release action:

  1. Bump the "version" parameter in lib/beaker-abs/version.rb appropriately based merged pull requests since the last release.
  2. Run ./release-prep to update Gemfile.lock and CHANGELOG.md.
  3. Commit and push changes to a new branch, then open a pull request against main and be sure to add the "maintenance" label.
  4. After the pull request is approved and merged, then navigate to Actions --> Release Action --> run workflow --> Branch: main --> Run workflow.
