Suite Configuration

The configuration and functionality of a suite will usually be covered by the use of Cylc. In which case, most of the suite configuration will live in the Cylc flow.cylc file. Otherwise, a suite is just a directory of files.

A suite directory may contain the following:

  • A file called rose-suite.conf, a configuration file in the modified INI format described above. It stores the information on how to install the suite. See rose-suite.conf for detail.

  • A file called rose-suite.info, a configuration file in the modified INI format described above. It describes the suite’s purpose and identity, e.g. the title, the description, the owner, the access control list, and other information. Apart from a few standard fields, a suite is free to store any information in this file. See rose-suite.info for detail.

  • An app/ directory of application configurations used by the suite.

  • A bin/ directory of scripts and utilities used by the suite.

  • An etc/ directory of other configurations and resources used the suite. E.g. fcm_make configurations.

  • A meta/ directory containing the suite’s configuration metadata.

  • opt/ directory. For detail, see Optional Configuration.

  • Other items, as long as they do not clash with the scheduler’s working directories. E.g. for a Cylc workflow, log*/, share/, state/ and work/ should be avoided.

Rose Configuration rose-suite.conf

The suite install configuration file rose-suite.conf should contain the information on how to install the suite.

Config opts

Hardcode an optional configuration to be used by the suite. It is generally better to specify optional configurations using the ROSE_SUITE_OPT_CONF_KEYS environment variable or --opt-conf-key argument both of which work with Cylc Rose and cylc install.

Config [env]

Specify the environment variables to export to the workflow scheduler. The usual $NAME or ${NAME} syntax can be used in values to reference environment variables that are already defined before the suite runner is invoked. However, it is unsafe to reference other environment variables defined in this section. If the value of an environment variable setting begins with a tilde ~, all of the characters preceding the first slash / are considered a tilde-prefix. Where possible, a tilde-prefix is replaced with the home directory associated with the specified login name at run time.

Config KEY= VALUE

Define an environment variable KEY with the value VALUE.

Config ROSE_VERSION= ROSE_VERSION_NUMBER

If specified, the version of Rose that starts the suite run must match the specified version.

Config CYLC_VERSION= CYLC_VERSION_NUMBER

If specified for a Cylc workflow, the Rose suite runner will attempt to use this version of Cylc.

Config [template variables]
Config KEY= VALUE

Define a variable KEY with the value VALUE for use in the flow.cylc file.

The assignment will be inserted after the hashbang line of the installed flow.cylc file.

New in version 2.0.0.

Config [jinja2:suite.rc]
Config KEY= VALUE

Define a Jinja2 variable KEY with the value VALUE for use in the flow.cylc file.

The assignment will be inserted after the #!jinja2 line of the installed flow.cylc file.

Changed in version 2.0.0: rose-suite.conf[template variables] are preferred at Rose 2.

Config [empy:suite.rc]
Config KEY= VALUE

Define a EmPy variable KEY with the value VALUE for use in the flow.cylc file.

The assignment will be inserted after the #!empy line of the installed flow.cylc file.

Changed in version 2.0.0: rose-suite.conf[template variables] are preferred at Rose 2.

Config [file:NAME]

Specify a file/directory to be installed. NAME should be a path relative to the run time $PWD.

E.g. file:app/APP=source=LOCATION.

For a list of configuration options and details on each see *[file:TARGET].

Config meta

Specify the configuration metadata for the suite. The section may be used by various Rose utilities, such as the config editor GUI. It can be used to specify the suite type.

Rose Configuration rose-suite.info

The suite information file rose-suite.info should contain the information on the identity and the purpose of the suite. It has no sections, only KEY=VALUE pairs. The owner, project and title settings are compulsory. Otherwise, any KEY=VALUE pairs can appear in this file. If the name of a KEY ends with -list, the value is expected to be a space-delimited list. The following keys are known to have special meanings:

Config owner

Specify the user ID of the owner of the suite. The owner has full commit access to the suite. Only the owner can delete the suite, pass the suite’s ownership to someone else or change the access-list.

Config project

Specify the name of the project associated with the suite.

Config title

Specify a short title of the suite.

Config access-list

Specify a list of users with commit access to trunk of the suite. A * in the list means that anyone can commit to the trunk of the suite. Setting this blank or omitting the setting means that nobody apart from the owner can commit to the trunk. Only the suite owner can change the access list.

Config description

Specify a long description of the suite.

Config sub-project

Specify a sub-division of project, if applicable.
