Example Playbook

This example is taken from molecule/default/converge.yml and is tested on each push, pull request and release.

---
- name: Converge
  hosts: all
  become: true
  gather_facts: true

  roles:
    - role: buluma.rsyslog
      vars:
        rsyslog_traditional_file_format: false
        rsyslog_omit_local_logging: false

The machine needs to be prepared. In CI this is done using molecule/default/prepare.yml:

---
- name: Prepare
  hosts: all
  become: true
  gather_facts: false

  roles:
    - role: buluma.bootstrap

Also see a full explanation and example on how to use these roles.

Role Variables

The default values for the variables are set in defaults/main.yml:

---
# defaults file for rsyslog

# To configure a server to receive logs, set rsyslog_receiver to true.
rsyslog_receiver: false

# To forward logs to another server, set rsyslog_remote to the hostname or
# the ipaddress of the receiving rsyslog server.
# Not setting this variable will not forward logs.
# rsyslog_remote: server1.example.com

# If rsylog_remote is set, sets the "selector" pattern for determining which
# messages to send to the remote server.  Default "*.*" sends everything.
# See `man rsyslog.conf`.
rsyslog_remote_selector: "*.*"

# If rsylog_remote is set, use TCP if true. UDP if false.
rsyslog_remote_tcp: true

# If rsylog_remote is set, destination port to use.
rsyslog_remote_port: 514

# Set the mode for new directories; only available in legacy template.
rsyslog_dircreatemode: "0700"

# Set the mode for new files; only available in legacy template.
rsyslog_filecreatemode: "0644"

# Set the mods enabled
rsyslog_mods:
  - imuxsock
  - imjournal

# Configure rsyslog minimally (may be in conflict with custom configuration files)
rsyslog_deploy_default_config: true

# Default rsyslogd rules
rsyslog_default_rules:
  - { rule: '*.info;mail.none;authpriv.none;cron.none', logpath: '/var/log/messages' }
  - { rule: 'authpriv.*', logpath: '/var/log/secure' }
  - { rule: 'mail.*', logpath: '-/var/log/maillog' }
  - { rule: 'cron.*', logpath: '/var/log/cron' }
  - { rule: '*.emerg', logpath: ':omusrmsg:*' }
  - { rule: 'uucp,news.crit', logpath: '/var/log/spooler' }
  - { rule: 'local7.*', logpath: '/var/log/boot.log' }

# Use the (obsolete) legacy, pre-v6 configuration file format, or the more
# modern # 'advanced' configuration file format available in v6 and up. The
# default is to use the 'legacy' format to not change config files for
# existing users of this role out of the blue.
# More information on the different formats on the rsyslog website:
# https://www.rsyslog.com/doc/v8-stable/configuration/conf_formats.html
rsyslog_config_file_format: legacy

# The rule conf to name to add to /etc/rsyslog.d/
# rsyslog_forward_rule_name: <to fill>

# Configure the rsyslog package to be `present`, or set to `latest` to install
# the latest available version.
rsyslog_package_state: present

# if set to false (legacy default to remain compatible to sysklogd), the domain
# part from a name that is within the same domain as the receiving system is
# stripped. If set to on, full names are always used.
rsyslog_preservefqdn: false

# Configure additional config files in /etc/rsyslog.d
# Example:
# rsyslog_rsyslog_d_files:
#   000-splunk:
#     content: |
#       auth,authpriv.* action(type="omfwd"
#                              target="splunk"
#                              port="514"
#                              protocol="tcp")
rsyslog_rsyslog_d_files: []

# Avoid sd_journal_get_cursor() failed: Cannot assign requested address messages
# due to logrotate
rsyslog_workaroundjournalbug: false

# Turns off message reception via local log socket
rsyslog_imuxsock_syssock: false

# Install additional rsyslog packages
# Example for installing rsyslog-elastisearch:
# rsyslog_features:
#   - gnutls
#   - elastisearch
rsyslog_features: []

# Default destination of rsyslog config file
rsyslog_dest_conf_file: "/etc/rsyslog.conf"

# Enable / Disable option OmitLocalLogging
rsyslog_omit_local_logging: true

# Allow using the traditional file format.
rsyslog_traditional_file_format: true
