Short for “acknowledgment”. When reviewing Beaker job results, this
means that a result has been reviewed and is valid. See also
nak.
Beaker server
Comprised of two main parts, the web UI and the scheduler. The web
UI is the main interface for Beaker users. The scheduler is
responsible for processing job workflows and assigning to recipes,
eventually culminating in the provisioning of systems via the lab
controller.
distro
In Beaker, a distro represents an OS major + minor version. Unlike a
distro tree, it says nothing about the arch or variant e.g.
RHEL-6.2.
distro tree
A distro tree is what is installed onto a system. It is a
combination of distro, variant and arch e.g. RHEL-6.2 Server
x86_64.
FQDN
Fully qualified domain name.
group
A group of one or more Beaker users.
group job
A job associated with a group. All group members are permitted
to cancel or modify the job. Refer to Access control for jobs.
group owner
The Beaker user who is responsible for a group. Group owners have
control over the group, including adding and removing members.
guest recipe
Guest recipes are used to run one or more recipe tasks in one
or more virtual machines as part of a larger host
recipe.
host recipe
A host recipe is a recipe which runs one or more guest
recipes in virtual machines.
job
The highest unit of work in Beaker, it is a container for one or
more recipe sets that are run independently of each other.
job owner
The Beaker user responsible for a job. By default this is the user who
submitted the job, unless it was submitted by a submission
delegate on behalf of the job owner instead.
lab controller
Main conduit of communication between systems and the beaker server.
Main responsibilities include provisioning of systems, monitoring of
systems via the external watchdog, transfer of system logs,
reporting of recipe task results, and importing distros.
loan recipient
The Beaker user to whom a system has been loaned. A loan grants
exclusive use of a system. Refer to Loans.
nak
Short for “negative acknowledgment”. When reviewing Beaker job results,
this means that a result has been reviewed but is waived. See also
ack, waiver.
pool access policy
The system access policy which is defined for a system
pool so that systems in the pool can share a common access
policy. This does not regulate access to the system pool
itself.
quiescent period
The ‘quiescent period’ is the minimum amount of time (in seconds)
between power operations.
A recipe set is contained within a job and can contain one or more
recipes. Any recipes within the same recipe set are run in parallel
with each other. This is needed for multihost recipes.
recipe
A recipe is contained within a recipe set. A recipe is a unit of
work, comprising an ordered sequence of recipe tasks that are run on
a system.
recipe task
A recipe task is contained within a recipe and is the smallest unit
of work in Beaker. A recipe task runs a specific task, the results
of which are reported to the beaker server.
submission delegate
A Beaker user (often an automated service) which is permitted to submit
jobs on behalf of other users. Refer to Submission delegates.
system
These make up Beaker’s inventory, and are the systems on which
recipes are run. They may not necesarily be a bare metal machine,
but could be a guest on a hypervisor.
system access policy
A set of rules which grant permissions on the system to other users and
groups in Beaker. Refer to Access policies.
system owner
The Beaker user responsible for maintaining a system. The system owner
has complete control over their system. When someone reports a problem
or requests a loan for the system, Beaker emails the request to the
system owner (and the rest of the notify CC list) for their attention.
system pool
A collection of systems form a system pool. A system pool can
be created by any Beaker user and the owner can changed to
either another user or another group. A system pool has
an pool access policy associated with it. Refer to
System pools and Shared access policies.
system user
The Beaker user who currently holds a reservation on a system (they are
using it, hence the term).
task
A task is designed to be run on a system, for the purposes of
running some arbitrary code written by the task’s author. A task is
uploaded to Beaker as an RPM and is run as a recipe task (that is to
say, a recipe task is an instance of a task).
test harness
The test harness is the software that manages the running of recipe
tasks on the system. It installs the tasks, creates the environment
in which they need to run, executes them in order, reports the
results backs to the server and uploads the logs to the lab
controller.
waiver
An acknowledgment that a result is invalid and should be disregarded.
Results can be waived by setting the response on the recipe set to
nak.
workflow
A workflow is used to describe job templates for running jobs of a
particular nature.
