Default variable details

Some of the debops.journald default variables have more extensive configuration than simple strings or lists, here you can find documentation and examples for them.

journald__configuration

The journald__*_configuration default variables define the contents of the /etc/systemd/journald.conf.d/ansible.conf configuration file. This file will be automatically parsed by the systemd-journald service and any active options will override the defaults defined in the /etc/systemd/journald.conf configuration file. You can read the journald.conf(5) manual page for more details about supported options.

Examples

Configure disable persistent storage for the journal logs, using the simple syntax:

journald__configuration:

  - 'Storage': 'volatile'

You can check the journald__default_configuration variable for the default contents of the configuration file.

Syntax

Each configuration entry in the list is a YAML dictionary. The simple form of the configuration uses the dictionary keys as the parameter names, and dictionary values as the parameter values. Remember that the parameter names need to be specified in the exact case they are used in the documentation (e.g. TTYPath, ReadKMsg), otherwise they will be duplicated in the generated configuration file. It's best to use a single YAML dictionary per configuration option.

If the YAML dictionary contains the name key, the configuration switches to the complex definition mode, with configuration options defined by specific parameters:

name

Required. Specify the name of the Journal configuration file parameter. The case is important and should be the same as specified in the configuration file or the journald.conf(5) manual page, otherwise the configuration entries will be duplicated.

Multiple configuration entries with the same name parameter are merged together in order of appearance. This can be used to modify parameters conditionally.

value

Required. The value of a given configuration option. It can be a string, number, True/False boolean or an empty string.

state

Optional. If not specified or present, a given configuration parameter will be present in the generated configuration file. If absent, a given parameter will be removed from the configuration file. If comment, the parameter will be present but commented out.

If the state is init, the parameter will be "primed" in the configuration pipeline, but it will be commented out in the generated configuration file. Any subsequent configuration entry with the same name will switch the state to present - this is used to define the default parameters in the role which can be changed via the Ansible inventory.

If the state is ignore, a given configuration entry will not be evaluated during role execution. This can be used to activate configuration entries conditionally.
