Usage: beaker-hostgenerator [options] <layout>
where <layout> takes the following form:
<platform>-<arch>[[<arbitrary-roles>,[...]].]<roles>[{<arbitrary-settings>,[...]}][-<arch>[[<arbitrary-roles>,[...]].]<roles>[{<arbitrary-settings>,[...]}]][-<layout>]
examples:
centos6-64mdca-32a
1 CentOS 6 64 bit node with roles = master, database, agent, dashboard
1 CentOS 6 32 bit node with roles = agent
debian8-64m-32ad-32ac-centos6-64a
1 Debian 8 64 bit node with roles = master
1 Debian 8 32 bit node with roles = agent, database
1 Debian 8 32 bit node with roles = agent, dashboard
1 CentOS 6 64 bit node with roles = agent
debian8-64m-windows8-64a
1 Debian 8 64 bit node with roles = master
1 Windows 8 64 bit node with roles = agent
example with arbitrary roles:
centos6-32compile_master,another_role.ma
1 CentOS 6 32 bit node with roles = master, agent, compile_master, another_role
example with arbitrary host settings:
centos6-64m{hypervisor=none\\,hostname=static1\\,my-key=my-value}-32a
1 CentOS 6 64 bit node with roles = master, hypervisor = none, node name = static1, and my-key = my-value
1 CentOS 6 32 bit node with roles = agent and the default hypervisor
example of a list within arbitrary host settings:
centos6-64m{hostname=static1\\,disks=[8,16],my-list=[my-value1]}-32a
1 CentOS 6 64 bit node with roles = master, node name = static1 and lists:
disks:
- 8
- 16
my-list:
- my-value1
1 CentOS 6 32 bit node with roles = agent and the default hypervisor
Generally, it is expected that beaker-hostgenerator output will be redirected to a file, for example:
beaker-hostgenerator centos6-64ma > host.cfg
This can then be used in a Beaker call instead of a static Beaker config.
